(2017) Duman, Enes; Coven, Ilker; Yildirim, Erkan; Yilmaz, Cem; Pinar, H.Ulas; Ozdemir, Ozgur; 0000-0003-0473-6763; 0000-0002-9057-722X; 0000-0002-2353-8044; 27593813; Q-2420-2015; ABI-3856-2020; AAK-2948-2021
AIM: The brain venous drainage dominance is generally divided into three groups; right or left dominance and co-dominance. There is no study in the literature examining the link between brain venous drainage and aneurysm formation or rupture. Our aim was to evaluate the association between venous dominancy, aneurysm formation and rupture. MATERIAL and METHODS: Eighty-six patients, who underwent cerebral digital subtraction angiography and who had cerebral aneurysms, were included in the study. The angiographic images, patient charts, and tomography images were scanned retrospectively. We recorded the aneurysm's location, size, dome to neck ratio (D/N); the patient's gender, age, whether there was a ruptured aneurysm, smoking history, and/or hypertension; dominance of venous drainage, aneurysm side, Fisher scores and the World Federation of Neurosurgical Societies (WFNS) Grading System for Subarachnoid Hemorrhage scores for patients who had a ruptured aneurysm. We assessed whether or not venous drainage was associated with rupture of the aneurysm and if venous dominance was a predisposing factor for aneurysm formation like location, size, and hypertension. RESULTS: There was a statistically significant association between venous dominance and side of aneurysm; and also a statistically significant association between venous dominance and rupture. There was a positive correlation between hypertension and rupture. The most common aneurysm location was the anterior communicating artery, followed by the middle cerebral artery. CONCLUSION: Brain venous drainage dominance may be a predisposing factor for aneurysm formation and it can be predictive for rupture.
Association between treatment with coil embolization of renal artery aneurysm and resistant hypertension
(2016) Duman, Enes; Yildirim, Erkan; Ciftci, Ozgur; Cifci, Egemen
Hypertension is the number one risk factor in preventable causes of death in the world. Resistant hypertension is defined as blood pressure that remains uncontrolled despite at least three antihypertensive medications including a diuretic. Treatment of hypertension includes many modalities from lifestyle changing to multiple drug using, angioplasty. In this case report, we aim to emphasize the effects of renal artery aneurysm treatment on resistant hypertension.
Balloon Dilatation of Iatrogenic Ureteral Strictures after Upper Urinary Tract Reconstruction
(2015) Duman, Enes; Yildirim, Erkan; Akillioglu, Ishak; Yucesan, Selcuk
Purpose: Open pyeloplasty is the gold standard treatment of uretero-pelvic junction (UPJ) stenosis. Although failure after open pyeloplasty or uretero-neosistosmy is not common, percutaneous or endoscopic interventions must be necessary in some cases. We present treatment of 6 pediatric patients by balloon dilatation after failed surgery. Material and Methods: Between 2008 and 2013 6 children were treated. Five patients had undergone open pyeloplasty for UP stenosis and, one has uretero-vesical anastomosis stricture after ureteroneosistostomy. Percutaneous antegrade balloon dilatation and double J stent placement were performed in three of six patients. In the other three patients retrograde endoscopic balloon dilatation and double J stent placement were performed. Results: Primary technical success was %50 and %100 for antegrade and retrograde approach respectively. Antegrade approach has failed in 3 patients (%50) and, retrograde approach and treatment were successful in all of these patients. Secondary and tertiary balloon dilatations were done through antegrade approach in 3 patients. Mean duration of double J stent was 114 days. As of today, five patients are followed smoothly. One patient who has UP stenosis underwent secondary open surgery. Conclusion: Balloon dilatation can be used safely in both antegrade and retrograde approaches because of lower profile of balloon catheters, so it could be considered as a first line treatment option after failed surgical treatment of upper urinary tract stenosis in children.

(2016) Ozden, Hale Turan; Coban, Gokcen; Duman, Enes; Togan, Turhan; https://orcid.org/0000-0002-4010-2883; P-7533-2014
Primary pyomyositis, a pyogenic infection of the skeletal muscle, is often seen in tropical and subtropical regions. In this article, we present a 16 years-old male patient, who applied to the emergency department with fever, hip pain, and inability to walk without history of trauma. The Multifocal pyomyositis diagnosis was made on the basis of clinical, laboratory and radiologic evaluation of gluteus maximus, medius and minimus, priformis and ilipsoas muscles. Meticilin sensitive Staphylococcus aureus was grown in patient's blood cultures. The patient was successfully treated with intravenous antibiotics (Sulbactam-ampicillin and ciprofloxacin) and ultrasonography guided drainage of abscesses. Although this infectious disease is rare, primary pyomyositis should be considered in the differential diagnosis of patients with fever, hip pain and claudication.

(2016) Pinar, Huseyin Ulas; Dogan, Rafi; Konuk, Ummu Mine; Cifci, Egemen; Duman, Enes; Karagulle, Erdal; Turk, Emin; Karaca, Omer; 27515323
Background: Increased central venous pressure secondary to an increase in intraabdominal pressure has been reported during laparoscopic surgery. However, no study has yet determined the effect of pneumoperitoneum on cross-sectional area (CSA) of central veins by ultrasonography during laparoscopic cholecystectomy. Herein, we aimed to quantify changes in CSAs of internal jugular (IJV) and subclavian veins (SCV) by ultrasonography during this surgery. Methods: This study included 60 ASA I-II patients scheduled for laparoscopic cholecystectomy surgery under general anesthesia. Pneumoperitoneum was performed with CO2 at 12 mmHg. The CSAs of right IJV and right SCV were measured using a 6 Mhz ultrasonography transducer in supine and neutral positions before anesthesia induction (T1), 5 min after connecting to mechanical ventilator (T2), 5 min after creation of pneumoperitoneum (T3), at the end of pneumoperitoneum (T4), and 5 min after desufflation and before extubation (T5) both at end-expiration and end-inspiration. Results: The comparison of IJV CSA at inspiration showed significant increase in T3 value compared to T2 value (p < 0.001). Similarly the expiratory measurements of IJV CSA demonstrated significant increase in T3 value compared to T2 value (p < 0.001). The comparison of inspiratory CSA measurements of SCV showed significantly increased in T3 (p = 0.009) than T2 value. In expiratory measurements there was a significant increase in T3 (p = 0.032) value compared to T2. All measurements of IJV and SCV SCAs both end-inspiration and end-expiration T5 values significantly decreased compared to T4 values (p < 0.001). Conclusions: Pneumoperitoneum with an intraabdominal pressure of 12 mmHg produces significant increases in IJV and SCV CSAs during laparoscopic cholecystectomy procedure. We believe that this finding may enhance our understanding of pneumoperitoneum-induced hemodynamic changes and facilitate catheterization attempts.
The Effectiveness of Computed Tomography-Guided Lumbar Epidural Steroid Injections for Spinal Pain Management: A Single Center Experience with 2-Year Follow-Up
(2017) Harman, Ali; Duman, Enes; Ozdemir, Adnan; 0000-0002-7386-7110; 0000-0001-5221-1879; K-9824-2013; K-4333-2018
Purpose: To determine the therapeutic value and long-term effects of Computed Tomography (CT)-guided translaminar and transforaminal lumbar epidural steroid injections for spinal pain management. Materials and methods: Between December 2011 and June 2013, 428 CT-guided epidural steroid injections of the lumbar spine for 310 patients were assessed retrospectively. There were 325 Translaminar (TL) (in 225 patients) and 103 Transforaminal (TF) (in 85 patients) injections performed. The clinical effectiveness of the injection after the therapy was assessed using Visual Analog Scale (VAS). The patients were classified into three groups (A-C) after injections according to the reduction in the VAS's. Results: Technical success rate of 100% without any major complication related to needle placement or drug administration. There were 27 (6.3%) reported minor complications (n: 3 orthostatic hypotension (0.7%) and n: 24 transient motor weaknesses of lower extremities (5.6%). The mean visual analog scores before and after the injections were recorded as 8.9 +/- 1.1 and 4.8 +/- 2.5 retrospectively (p 0.001). In 23 of 310 patients epidural injections were repeated in different times during study and 73 epidural injections (n: 61 TL and n: 12 TF) were performed. Conclusion: CT guided epidural injection in the lumbar spine is safe, repeatable and efficacious pain management technique. Both translaminar and transforaminal epidural steroid injections can provide reliable pain relief for up to average 5.5 and 5.6 months respectively.

(2017) Duman, Enes; Yildirim, Erkan; Ozdemir, Adnan; Arslan, Serdar; Aytekin, Cuneyt; Bovyat, Fatih; 0000-0002-9057-722X; F-4230-2011; ABI-3856-2020
Background: To present our findings obtained from the treatment of wide-necked intracranial neurysms with flow diverter stents. Patients and Methods: Intracranial aneurysms were determined in 19 patients (14 females, 5 males; mean age, 56.6 years) between May 2011 and June 2014, and the patients were treated using flow diverter stents. A total of 28 flow diverter stents, including 9 Silk and 19 Pipeline stents were used. Occlusion rates evaluated with computed tomography at the end of month 6 and digital subtraction angiography after one year, intraoperative success, morbidity and mortality rates were determined. Results: A total of 20 endovascular interventions, including two interventions in two different aneurysms in one patient were performed in 19 patients. Flow diverter stents were successfully implemented for wide-necked aneurysms at a success rate of 100%. Coil treatment had previously been performed in four patients. Aneurysm occlusion rates were 77.2% at month 6 and 90.9% at the end of month 12. Conclusion: The use of flow diverter stents is a reliable and effective method in the treatment of wide-necked intracranial aneurysms with high aneurysm occlusion, and low morbidity and mortality rates.
Endovascular Treatment of Acute Stroke due to the Floating Carotid Thrombus with Intra-Arterial Tissue Plasminogen Activator and Stenting
(2015) Duman, Enes
54-year-old male patient was admitted to emergency service with bilateral loss of sight, consciousness and a Glasgow Coma Scale score of 15. His neurologic examination revealed no lateralized deficit but left homonymous hemianopia. Brain CT and diffusion MRI showed acute infarction in the right parietal and occipital lobes. There was a wide penumbra region on brain perfusion CT. The selective angiography showed preocclusive stenosis at the origin of right internal carotid artery (ICA) and massive floating thrombus (FT) in the cervical ICA segment. We report successful endovascular treatment of FT in the ICA using intra-arterial tissue plasminogen activator and stenting.

(2017) Duman, Enes; Coven, Ilker; Yildirim, Erkan; Yilmaz, Cem; Pinar, H.Ulas; 0000-0002-2353-8044; 0000-0003-0473-6763; 0000-0002-9057-722X; 27593785; AAK-2948-2021; Q-2420-2015; ABI-3856-2020
AIM: Flow diverter (FD) stents have been used in the treatment of unruptured intracranial aneurysms. There are a few studies that report the use of these devices in ruptured blister-like aneurysms. We present 5 consecutive patients, who had ruptured intracranial wide necked or side branch close to the neck of saccular aneurysms, with no other treatment options, treated with FD stents and coil embolization. MATERIAL and METHODS: Between September 2012 and April 2015, 139 ruptured aneurysms of 133 consequent patients were treated. Of these, 48 were surgically treated aneurysms. Five of the remaining 85 aneurysms treated with FD stents. Three aneurysms were in the posterior communicating artery, and 2 were in the supraclinoid internal carotid artery (ICA). Partial coil embolization was performed in addition to FD stents in three patients. All patients were treated in the first 3 days after bleeding. RESULTS: Technical success was 100%. Inappropriate deployment of silk stent and partial thrombus formation occurred in one patient due to the jailed micro-catheter. Inappropriate apposition of stent was corrected with a balloon, and the thrombus resolved with tirofiban, tissue plasminogen activator (t-PA) injections. No other complication or death occurred related to the procedure. One patient who had a giant ICA aneurysm and Fisher grade 4 bleeding died due to vasospasm, cerebral edema and sepsis on the postoperative 13th day. The other patients were followed-up uneventfully with computed tomography angiography (CTA) at 6th month and digital subtraction angiography (DSA) at 12th month. CONCLUSION: FD stents can be used in the treatment of ruptured large wide necked or side branch close to the neck of saccular aneurysms when other treatment options can not be used.

(2018) Duman, Enes; Yildirim, Ismail Okan; Firat, Ali; Celik, Huseyin; Sarac, Kaya
Objective: The purpose of this study was to evaluate efficacy outcomes following prostate artery embolization (PAE) for the treatment of benign prostatic hyperplasia (BPH) patients with high comorbidity. Materials and Methods: This retrospective study included 22 patients treated with PAE from May 2015 to June 2017. Patients with Charlson comorbidity index >= 2, International Prostate Symptom Score (IPSS) >12, prostate specific antigen (PSA) levels <4 ng/mL or between 4 and 10 ng/mL with negative prostate biopsy and total prostate volume (TPV) >90 cm(3) were included. Total PSA, maximum flow rate (Q(max)), TPV, IPSS, post-voiding residual (PVR) values were recorded in all patients in the urology clinic before PAE and at 3 and 6 months after PAE. Results: The average patient age was 73.86 +/- 6.25 years and operative time was 80 minutes (range, 60-120 min). Pre-PAE and 6-month post-PAE values were: IPSS: 25.18 +/- 6.75 an d 11.27 +/- 3.29 (p<0.05), Q(max): 8.31 +/- 3.12 and 17.22 +/- 3.23 (p<0.05), PVR: 87.9 +/- 19.25 and 25.86 +/- 7.72 (p<0.05), TPV: 134.45 +/- 57.56 and 86 +/- 15.4 (p<0.05), and PSA: 3.89 +/- 1.26 and 2.11 +/- 1.06 (p<0.05). Embolization was performed unilaterally due to atherosclerosis and strictures in the internal iliac artery branches in 2 patients. After the procedure, 2 patients experienced transient hematuria which did not require bladder irrigation, 1 patient had acute urinary retention due to dysuria, and 1 patient had transient hematospermia. Conclusion: PAE may be an alternative treatment method in BPH patients with high comorbidity.

(2018) Kal, Ali; Duman, Enes; Sezenoz, Almila Sariguel; Ulusoy, Mahmut Oguz; Kal, Oznur; https://orcid.org/0000-0001-7544-5790; https://orcid.org/0000-0002-7030-5454; https://orcid.org/0000-0002-7751-4961; 28730400; AAJ-4936-2021; AAJ-4860-2021; AAJ-7586-2021
PurposeTo evaluate whether retrobulbar blood flow and choroidal thickness (CT) are affected in patients with rheumatoid arthritis (RA), and the relationship between these values.MethodsWe evaluated 40 eyes of 20 RA patients and 40 eyes of 20 healthy controls. The enhanced depth imaging optical coherence tomography, color Doppler imaging, was held. Statistical analysis was performed.ResultsPeak systolic velocity (PSV) of ophthalmic (OA) and central retinal artery (CRA) were significantly higher in RA. No significant difference was observed when end-diastolic velocity (EDV) of OA and CRA was compared between the groups. The resistivity index (RI) of OA and CRA was higher in RA. Perifoveal/subfoveal CT was lower in RA. Negative correlation was detected between the RI of OA and the perifoveal CT, and a positive correlation was detected between RI of CRA and CT.ConclusionsOcular hemodynamics is effected by RA and can exaggerate ocular complications of various vascular diseases such as diabetes mellitus, hypertension, retinal vascular occlusions.

(2017) Kircelli, Atilla; Coven, Ilker; Duman, Enes; Pinar, Huseyin Ulas; Basaran, Betul; 0000-0003-0473-6763; 0000-0003-2109-1274; 28784938; Q-2420-2015; AAK-5299-2021
Background: Aneurysmal subarachnoid hemorrhage (aSAH) is a destructive syndrome with a mortality rate of 50%. Recent studies have also suggested a high pervasiveness of hypothalamic-pituitary insufficiency in up to 45% of patients after aSAH. Prolactin has been associated with the pathogenesis of hypertensive irregularities that are linked to pregnancy. Material/Methods: We identified a group of 141 patients with spontaneous SAH due to a ruptured cerebral aneurysm; these patients were operated on at our institution's Neurosurgery and Interventional Radiology Department between 2011 and June 2015. All of the data were obtained retrospectively from medical records. Results: The hormonal abnormalities observed in the initial 24 h after ictus in subjects with subarachnoid SAH were caused by stressful stimulation aggravated by intracranial bleeding. Conclusions: The elevated prolactin levels that occur in patients with aSAH can be used in conjunction with other auxiliary factors that we believe may be beneficial to vasospasm.
IS THERE A REAL CORRELATION BETWEEN RED CELL DISTRIBUTION WIDTH AND PERIPHERAL ARTERIAL DISEASE?
(2017) Duman, Enes; Kulaksizoglu, Sevsen; Cifci, Egemen; Ozulku, Mehmet; 0000-0002-7613-2240; 30581327; AAI-8932-2021
Background: Few data is available concerning the association between peripheral arterial disease (PAD) and red cell distribution width (RDW). In this study, we analyzed the relationship between RDW and atherosclerosis of the vessels other than coronary arteries in patients who had undergone digital substraction angiography (DSA). Methods: This study included 730 patients who had undergone DSA. Patients were divided into two groups according to their angiographic images. The association between RDW and atherosclerosis of peripheral arteries was analyzed. The relationship between atherosclerosis and smoking, hypertension (HT), diabetes mellitus (DM), hs-CRP, hemoglobin, white blood cell (WBC), triglyceride, total cholesterol, HDL and LDL cholesterol levels was assessed. Results: Atherosclerosis was observed more common in male and patients with older age, HT, DM and smoking (p< 0.001). hs-CRP and WBC levels were both in significantly positive association with atherosclerosis (p< 0.05). However, there were no significant differences in the RDW levels, hemoglobin, triglyceride, total cholesterol, LDL and HDL cholesterol levels in the groups (p> 0.05). Conclusions: Our results seem to demonstrate that older age, male gender, HT, DM and smoking are powerful risk factors for PAD. In contrast to the previous reports, RDW levels are found not to be associated with atherosclerosis of peripheral arteries.
Laparoscopic gastrostomy under awake thoracic epidural anesthesia: A successful experience
(2018) Pinar, Huseyin Ulas; Karaca, Omer; Duman, Enes; Dogan, Rafi; 30028480
General anesthesia is the first choice as an anesthesia method particularly for abdominal operations. However, because neuromuscular blockade induced during general anesthesia will increase atelectasis in a patient with pulmonary disease, it will also increase postoperative ventilator dependence, which will be even more apparent in cases of chronic obstructive pulmonary disease (COPD) that pose a risk, particularly for postoperative complications. Herein, thoracic epidural anesthesia (TEA) was found to be a better option for our patient with severe COPD and stage IV lung cancer, as it provided sufficient anesthesia and better postoperative care for laparoscopic gastrostomy.
Percutaneous Placement of Pancreatico-biliary Drainage Catheter for the Treatment of Complicated Pancreatic Anastomotic Leakage: an Alternative Treatment Option
(2016) Duman, Enes; Yildirim, Erkan; 0000-0002-9057-722X; 27994344; ABI-3856-2020
A 58-year-old female patient who had anastomotic leakage after a Whipple operation was treated with a percutaneously placed pancreatico-biliary drainage catheter. Complete secondary healing of the anastomotic defect and leakage was seen on control cholangiography examination on the 35th postoperative day, and the pancreatico-biliary drainage catheter was removed. She was discharged on the 39th postoperative day uneventfully. Percutaneous pancreatico-biliary drainage should be kept in mind as an alternative treatment option of complicated pancreatic anastomotic leakage after a Whipple operation.

(2018) Silahli, Musa; Duman, Enes; Gokmen, Zeynel; Toprak, Erzat; Gokdemir, Mahmut; Ecevit, Ayse; 0000-0002-2746-0547; 0000-0002-2877-1232; 0000-0002-5676-2747; 0000-0002-2232-8117; 30410129; AAX-9343-2021; AAJ-8069-2021; ABI-5902-2020; N-4174-2014; AAJ-4616-2021
Objectives: To compare the effect of umbilical cord milking and early cord clamping on thymic size, and neonatal mortality and morbidity in preterm infants. Methods: This single-center, prospective, double-blind, randomised controlled study was conducted at Baskent University, Konya Education and Research Centre, Konya, Turkey, between October 2015 and April 2016. Pregnant women who delivered before 32 weeks of gestation were randomised to receive umbilical cord milking (group 1) or early cord clamping (group 2). Ultrasonographic evaluation was performed in each newborn by an experienced radiologist within the first 24 hours of life. Thymic size was estimated in line with literature. SPSS 15 was used for all data analyses. Results: There were 38 subjects in group 1 and 37 in group 2. There were as many infants in the two groups (p>0.05) The haemoglobin levels was higher in group 1, but not significantly (p=0.213). The absolute neutrophil count in group 1 was significantly lower (p=0.017) than group 2. In terms of neonatal mortaility and morbidity, there were no significant differences between the groups (p>0.05). Conclusion: Umbilical cord milking was not associated with thymic size during the the first 24h of life.
Safen ven yetmezliği tedavisinde endovenöz lazer ile ablasyon: 980 Nm ile 1470 Nm dalga boyundaki lazer enerjisinin tedavideki etkinliğinin karşılaştırılması
(Başkent Üniversitesi Tıp Fakültesi, 2011) Duman, Enes; Yıldırım, Erkan
Alt ekstremite venöz yetmezliği ve buna bağlı oluşan varisler, toplumda oldukça sık rastlanan (%20-40), yaşam kalitesini bozan ve bazı durumlarda ciddi komplikasyonlara da yol açabilen önemli bir sağlık problemidir. Yüzeyel venöz yetmezlik ve varislerin tedavisinde uzun süredir cerrahi yöntemler kullanılmaktadır. Bu yöntemlerin genel veya spinal anestezi, hastanede kalış süresinin daha fazla olması, artmış komplikasyonlar gibi dezavantajları vardır. Bu dezavantajları ortadan kaldırabilmek için yeni tedavi yöntemlerine ihtiyaç duyulmuştur. Yüzeyel venöz yetmezlik ve varis tedavisinde son yıllarda Endovenöz Lazer Ablasyon (EVLA) ve köpük skleroterapi yöntemleri cerrahiye alternatif en güncel tedavi yöntemleridir. EVLA‘ nın en önemli avantajları, lokal anestezi altında yapılması, ağrısız olması, yara-kesi izi olmaması ve işlemden hemen sonra hastanın ayağa kalkıp yürüyebilmesidir. Bu avantajları nedeniyle EVLA yöntemi kısa sürede tüm dünyada venöz yetmezliğin giderilmesinde ilk seçilecek tedavi yöntemi durumuna gelmiştir. Endovenöz tedavi için kullanılan çeşitli dalga boylarında lazer sistemleri vardır. 810nm, 940nm, 980nm, 1064nm dalga boylarındaki lazer sistemleri hemoglobin spesifik, 1320nm, 1470nm dalga boylarındaki lazer sistemleri ise damar duvarındaki intertisyel suya spesifiktir. Bizim çalışmamızda 980 nm dalga boyunda lazer enerjisi ve 1470 nm dalga boyunda lazer enerjisi ile yapılan ablasyon tedavilerinde teknik başarı, postoperatif ağrı skorları ve komplikasyon oranlarının karşılaştırılması amaçlanmıştır. Semptomatik safen ven yetmezliği olan, derin ven trombozu, belirgin sistemik hastalığı, ciddi alt ekstremite arteriel hastalığı, karaciğer yetmezliği, lokal anesteziklere belirgin ilaç alerjisi, koagülasyon bozukluğu olmayan, işlem yapılacak bölgede aktif cilt enfeksiyonu bulunmayan ve gebe olmayan toplam 73 hastaya (84 ekstremite) EVLA tedavisi uygulandı. İşlem öncesi hastaların CEAP skorları kaydedildi. Bu hastalar 980 nm ve 1470 nm dalga boyuna sahip lazer sistemleri ile tedavi edilen olmak üzere iki gruba iii ayrıldı. 980 nm dalga boyuna sahip lazer ile tedavi edilen hasta sayısı 47 (54 ekstremite), 1470 nm dalga boyuna sahip lazer ile tedavi edilen hasta sayısı 26‘dır (30 ekstremite). Hastalar tedavi sonrası orta basınçlı (class II) varis çorabı giydirilerek mobilize edildi. Hastalara 10 gün süre ile analjezik/antienflamatuar tedavi verildi. Hastaların 1.hafta ve 1.ay ultrasonografi kontrolleri yapılarak şemaya göre ağrı skorları, işlem başarısı ve erken dönem komplikasyonları kaydedildi. Çalışmamızda EVLA tedavisi sonrasında erken dönem minör komplikasyonlar ve ağrı skorları ile tedavide kullanılan lazer dalga boyu ve santimetreye verilen enerji miktarının ilişkisinin olmadığı anlaşılmıştır. 980 nm dalga boyunda lazer kullanıldığında santimetreye ortalama 100 J, 1470 nm dalga boyunda lazer kullanıldığında santimetreye ortalama 50 J enerji verilmesi durumunda tüm hastalarda tam oklüzyon sağlanabilmektedir. Yapılan tümesan anestezi kalitesi ve lazer fiberinin geri çekim hızı tedavi etkinliğini belirleyen diğer önemli parametrelerdir. EVLA tedavisini yapan hekimin mutlaka Doppler USG deneyiminin olması gerekmektedir. Dolayısı ile bu tedavi Doppler USG deneyimi en fazla olan girişimsel radyologlar tarafından yapılmalıdır.
Severe Hypernatremia Associated Catheter Malposition in An Intensive Care Patient
(2016) Silahli, Musa; Gokdemir, Mahmut; Duman, Enes; Gokmen, Zeynel; 0000-0003-0944-7178; 0000-0002-2746-0547; 0000-0002-5676-2747; 27555161; AAB-5059-2022; AAX-9343-2021; AAJ-8069-2021; N-4174-2014
We present a catheter related severe hypernatremia in a 2-month-old baby who was admitted to the pediatric intensive care. Imbalance of plasma sodium is commonly seen in pediatric intensive care patients. The water and sodium balance is a complex process. Especially, brain and kidneys are the most important organs that affect the water and sodium balance. Other mechanisms of the cellular structure include osmoreceptors, Na-K ATPase systems, and vasopressin. Hypernatremia is usually an iatrogenic condition in hospitalized patients due to mismanagement of water electrolyte imbalance. Central venous catheterization is frequently used in pediatric intensive care patients. Complications of central venous catheter placement still continue despite the usage of ultrasound guidance. Malposition of central venous catheter in the brain veins should be kept in mind as a rare cause of iatrogenic hypernatremia. (C) 2016 Elsevier Inc. All rights reserved.
Traumatic craniocervical junction ligamentous and brain stem injuries and retroclival hematoma: unusual combination of craniocervical junction injuries
(2017) Gokdemir, Mahmut; Cifci, Bilal Egemen; Cifci, Gokcen Coban; Duman, Enes; 0000-0002-5676-2747; N-4174-2014
Cervical spine injuries are common in pediatric population and usually seen in craniocervical junction due to the anatomical and physiological differences. Combination of rapid hyperextension/hyperflexion traumas due to highspeed motor vehicle accident are known to be the reason of ligamentous injury and retroclival epidural hematoma. Our aim is to describe a rare combination injury of the the apical ligament, retroclival epidural hematoma and the suspicion of brain stem slits, due to rapid hyperextension/hyperflexion and rotational trauma with high-speed motor vehicle accident in a 3 year 8 month old girl. The cervical spine was immobilized with a Philadelphia collar. She is still under treatment in the pediatric intensive care unit with a Glascow Coma Scale of 8 for six months.
