Item Vesicouterina fistula: Youssef's syndrome(2015) Cicek, Tufan; Duman, Enes; Toprak, Erzat; Kosan, MuratVesico-uterin fistula is a rare type of fistulas and can be diagnosed frequently after surgery. First described by Youssef in 1957. Clasically findings are; cyclic haematuria without urinary incontinence and secondary amenorrhea. The patient was referred to our clinic for cyclic hematuria and she was diagnosed with vesicouterine fistula by radiological imaging methods and a cystoscopy procedure. Being a rare occurrence, this case was reported with a discussion of the relevant literature.Item Endovascular Treatment of Acute Stroke due to the Floating Carotid Thrombus with Intra-Arterial Tissue Plasminogen Activator and Stenting(2015) Duman, Enes54-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.Item The effect of pneumoperitoneum on the cross-sectional areas of internal jugular vein and subclavian vein in laparoscopic cholecystectomy operation(2016) Pinar, Huseyin Ulas; Dogan, Rafi; Konuk, Ummu Mine; Cifci, Egemen; Duman, Enes; Karagulle, Erdal; Turk, Emin; Karaca, Omer; 27515323Background: 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.Item Endovascular Treatment of Wide Necked Ruptured Saccular Aneurysms with Flow-Diverter Stent(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-3856-2020AIM: 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.Item 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-8932-2021Background: 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.Item Association Between Brain Venous Drainage, Cerebral Aneurysm Formation and Aneurysm Rupture(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-2948-2021AIM: 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.Item High Prolactin Level as a Predictor of Vasospasm in Aneurysmal Subarachnoidal Hemorrhage(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-5299-2021Background: 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.Item 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-4174-2014Cervical 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.Item Laparoscopic gastrostomy under awake thoracic epidural anesthesia: A successful experience(2018) Pinar, Huseyin Ulas; Karaca, Omer; Duman, Enes; Dogan, Rafi; 30028480General 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.Item 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, ErkanAlt 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.
