Aims: To evaluate the feasibility of quantitative analysis of muscle stiffness by Acoustic Radiation Forced Impulse (ARFI) elastography over a course of graduate isometric voluntary contractions. Material and methods: The stiffness of the bilateral biceps muscle of 13 healthy volunteers was measured in real time by ARFI elastography, while the forearm was in neutral-extended position, 90 degree self-flexed positions and 90 degree self-flexed position, with altered weights ranging from 1 to 8 kg placed on flattened palmar surfaces consecutively. The determined increases in biceps muscle stiffness were measured for both arms and correlated with the loadings weights adopted at progressive trial stages. Results: The mean shear wave velocity (SWV) values of biceps muscles in a neutral position, in 90 degree flex position and 90 degree flex position with 1 to 8 kg weights on palmar surfaces were 2.162 +/- 0.302 m/sec, 3.382 +/- 0.581 m/sec, and 3.897 +/- 0.585 to 5.562 +/- 0.587 m/sec, respectively. Significant correlations between the muscle SWV values and related palmar weights and between the SWV values of right and left sides at different trial stages were identified (r=0.951 and r=0.954, respectively). A mutual propagation path of deep regions to entire areas was described to account for the distribution of increase in stiffness with increases in palmar weights. The confidence of method regarding inter-observer difference was confirmed by the correlation analyses of the results (r=0.998). Conclusions: ARFI elastography is a feasible imaging modality for quantifying the stiffness of isometrically voluntarily contracting muscles.

(2015) Yavuz, Alpaslan; Batur, Abdussamet; Bulut, Mehmet Deniz; Bora, Aydin; Goya, Cemil; Andic, Cagatay; Beyazal, Mehmet; Olmez, Sehmus; 0000-0003-2865-9379; 0000-0002-7288-3936; 0000-0001-8581-8685; 0000-0001-8581-8685; 0000-0002-8796-988X; 25672511; JPK-9408-2023; ABG-1212-2020; AAC-1482-2020; AAM-3180-2021; AAM-1671-2021; H-3947-2014
To evaluate anterior hepatic grooves (AHGs) associated with hepato-diaphragmatic mesocolic indentations (Chilaiditi sign) and to delineate the incidence and potential clinical significance of this association. Between November 2011 and June 2014, abdominal computed tomography examinations of 2,314 patients with varied indications were retrospectively reviewed. Patients were surveyed consecutively for the Chilaiditi sign and syndrome, and cases with grooves at the antero-inferior hepatic surface enclosing the adjacent mesocolic indents were determined. The incidence of AHGs and their predominance by gender and age were determined. The potential clinical significance of AHGs associated with Chilaiditi syndrome and their possible effect on liver volume were assessed. The incidences of AHGs were similar between genders (p = .461 and p = .646) and age (p = .113 and .621, respectively) among total cohort and patients with Chilaiditi sign, respectively. There was no significant correlation between AHGs and Chilaiditi syndrome (p = .506); no efficacies of AHGs to liver volume were assessed (p = .413). The AHGs are rare adaptive changes in shape of the liver without a significant effect on liver volume. This overlooked phenomenon is likely derived from the Chilaiditi sign, but has no significant correlation with Chilaiditi syndrome. Future studies with extended series are encouraged to reveal the possible significance of this phenomenon based on concerned surgical interventions.
Comparison of Sedoanalgesia Versus Ultrasound-Guided Supraclavicular Brachial Plexus Block for the Prevention of the Pain During Endovascular Treatment of Dysfunctional Hemodialysis Fistulas
(2019) Gedikoglu, Murat; Andic, Cagatay; Guzelmansur, Ismail; Eker, Hatice Evren; Bolgen, Cagatay; 31342099
Purpose Although intravenous sedation and analgesia have been widely used as a first choice to relieve pain during treatment of dysfunctional hemodialysis fistulas by interventional radiology, the sedoanalgesic drugs have a considerable risk of respiratory depression, especially in hemodialysis patients. In this study, we compared the utility and efficiency of ultrasound-guided supraclavicular brachial plexus block versus sedoanalgesia for the prevention of pain during endovascular treatment of dysfunctional hemodialysis fistulas Materials and Methods Patients were randomized into two groups: ultrasound-guided supraclavicular brachial plexus block (n = 34) or sedoanalgesia group (n = 34). A visual analogue scale from no pain (= 0) to worst pain possible (= 10) was used to assess the pain intensity. Patient and operator satisfaction were graded from 0 to 2: 0, not satisfied at all; 1, partially satisfied; 2, satisfied (very well or complete satisfaction). Both groups were compared in terms of pain scores, patient and operator satisfaction as well as complications. Results The median pain score was significantly lower in the block group compared to the sedoanalgesia group, 0 (0-4) versus 6 (2-10), p = 0.0001. Patient satisfaction and operator satisfaction were significantly higher in the block group than in the sedoanalgesia group (p = 0.0001). Severe oxygen desaturation occurred in five (14.7%) patients following the administration of sedoanalgesia. No side effects or complications related to block procedure occurred in any patient. Conclusion Ultrasound-guided supraclavicular brachial plexus block has advantages over the sedoanalgesia during endovascular treatment of dysfunctional hemodialysis fistulas. It can provide safe and efficient analgesia with excellent procedural satisfaction in adult hemodialysis patients.

Early Treatment of Ruptured Blood Blister-Like Aneurysms of the Internal Carotid Artery With Flow Diverters Using Single Antiplatelet Therapy: A Single-Center Experience With Long-Term Follow-Up
(2021) Tanburoglu, Anil; Andic, Cagatay; 0000-0001-9627-3502; 0000-0001-8581-8685; 34630284; AAK-1876-2021; AAM-1671-2021
Background and Purpose: Blood Blister-like aneurysms (BBAs) of the internal carotid artery (ICA) are rare entities of cerebral aneurysms. FD use in acutely ruptured aneurysms, timing of treatment and antiplatelet regimen are main debate topics in clinical practice when the treatment decision is flow diversion. The aim of this study is to report the safety and efficacy of a single-center FD treatment for ruptured BBAs in the early phase of SAH using the SAPT regimen. Material and Method: This study involved a retrospective analysis of a prospectively collected database. Records of patients admitted to our clinic and treated by endovascular route on ruptured BBA between January 2013 and December 2020 were reviewed. Ruptured supraclinoid ICA BBAs treated with FD devices with SAPT within 48 h from ictus of SAH are included. BBA of atypical anatomic locations, other endovascular techniques performed, and delayed admissions (> 48 h) were excluded from the study. Demographic, clinical and angiographic features of patients and aneurysms, FD types and numbers, periprocedural complications, immediate and follow-up angiographic and clinical outcomes were recorded. Results: A total of six patients with ruptured BBAs treated via FDs within 48 h and used SAPT were included in the study. The mean age was 41.6 years (range from 34 to 45 years), and four of six patients were female. All patients were treated within 48 h after ictus, and the mean treatment day was 1.33 days. One patient received ticagrelor, and five patients received prasugrel as SAPT for one year after treatment. No procedure-related death and rebleeding were recorded. One (16.7 %) treatment responsive procedure-related complication occurred (transient ischemia). Overall good outcome rate was 83.3%. One patient died due to pneumonia. The immediate control angiograms showed complete occlusions of BBAs in one patient (16.6%). The complete occlusion rate was 100 % for five survivors at the control angiogram. The median follow-up was 49.5 months. Conclusion: This single-center experience suggests that early treatment (< 2 days) within SAH of ruptured BBAs with FDs using SAPT is safe and effective in terms of clinical and radiological long-term outcomes.

(2021) Suner, Halil İbrahim; Tanburoglu, Anil; Durdag, Emre; Civi, Soner; Gunesli Yetisken, Aylin; Kardes, Ozgur; Andic, Cagatay; Tufan, Kadir; 0000-0002-5957-8611; 0000-0003-2854-941X; 0000-0001-9627-3502; 0000-0001-8581-8685; 33890450; AAJ-5381-2021; P-5895-2018; AAK-1876-2021; AAM-1671-2021
Background/aim: We aimed to determine in which cases this procedure may be more effective based on the data of patients who underwent decompressive hemicraniectomy (DHC). Material and methods: Overall, 47 patients who underwent DHC due to acute middle cerebral artery (MCA) infarction between January 2014 and january 2019 were retrospectively investigated. These patients were divided into two groups: those who died after DHC (Group A) and those who survived DHC (Group B). The groups were compared in terms of various parameters. We investigated whether the patient's modified Rankin scale (mRS) status changed depending on age (> 60 and < 60 years). Results: The median age of all patients was 65 (37-80) years; groups A and B had median ages of 66.5 (37-80) and 61 (44-79) years (p = 0.111), respectively; 55.3% patients were male. The elapsed times until hospitalization after the onset of symptoms were 4.5 and 3 h in groups A and B, respectively (p = 0.014). The median GCS score at the time of admission was 7 (5-12) and 10 (8-14) in groups A and B, respectively (p = 0.0001). At the time of admission, 63.3% patients in group A had anisocoria, whereas no patient in group B had anisocoria (p = 0.0001). In postoperative period, 40% patients in group A and all patients in group B received AC/AA treatment. The survival of patients aged < 60 and > 60 years who underwent DHC for MCA infraction was 61.5% and 26.5%, respectively (p = 0,041). The median mRS of patients < 60 and > 60 years were 4 (1-6) and 6 (1-6), respectively (p = 0.018). Conclusion: Age, DHC timing, and elapsed time until hospitalization or access to treatment directly affect the functional outcome and survival in MCA-infarcted patients who underwent DHC. In patients in whom the medical treatment fails, early DHC administration will increase survival without waiting for neurological worsening once herniation is detected radiologically.

(2017) Andic, Cagatay; Kardes, Ozgur; Durdag, Emre; Gedikoglu, Murat; Akin, Sule; 0000-0001-8581-8685; 0000-0003-2854-941X; 0000-0001-6939-5491; 0000-0001-6423-1076; 27811177; AAM-3180-2021; P-5895-2018; AAK-1734-2021; AAJ-2094-2021
Background and purpose In patients with aneurysmal subarachnoid hemorrhage, deciding the optimal treatment strategy is challenging in the presence of severe and symptomatic vasospasm and the existing literature is limited. The purpose of this study was to evaluate the safety and effectiveness of endovascular treatment of intracranial aneurysms and the feasibility of stent-assisted coiling during severe and symptomatic vasospasm. Materials and methods Fifteen consecutive patients with 18 aneurysms who underwent endovascular treatment during severe and symptomatic vasospasm were included in the study. Patient and aneurysm characteristics, treatment technique, and clinical and angiographic outcomes were retrospectively evaluated. Results Aneurysms were treated by the following techniques: single catheter coiling in 9, stent-assisted coiling in 8 (3 aneurysms with Y-configuration double stents), and balloon-assisted coiling in 1. All patients showed angiographic improvement of vasospasm after treatment including a noticeable dilation of the spastic parent arteries following deployment of the stents. According to the immediate post-treatment angiography results, 14 aneurysms (77.8%) had class I occlusion and 4 (22.2%) had class II occlusion. Three patients died during the course of subarachnoid hemorrhage. Mortality was related to the poor grade (Hunt and Hess grade V) and cardiovascular complications in two and refractory vasospasm one patient. The remaining patients had favorable clinical outcomes at follow-up (modified Rankin Scale 0-2). Conclusions Endovascular treatment of intracranial aneurysms during severe and symptomatic vasospasm is safe and effective. Stent-assisted coiling in the presence of severe vasospasm is also feasible in wide-necked aneurysms with the additional benefits of mechanical vasodilation.

(2018) Andic, Cagatay; Gunesli, Aylin; Alkan, Ozlem; Erol, Ilknur; Suner, Halil Ibrahim; 30090148
Seckel syndrome and Moyamoya diseases are different entities that rarely associated with each other. Several cases presenting with both these diseases were reported. Intracerebral artery aneurysms and collateral vessels can be seen with Moyamoya. They are commonly treated with medical treatment. We present a 12-years old patient with both Seckel syndrome and Moyamoya disease presented with middle cerebral artery aneurysm which was treated with endovascular modalities.
Endovascular Treatment of Vascular Injuries in the Craniocervical Region With a Graft Stent: A Single-Center Experience
(2023) Tanburoglu, Anil; Andic, Cagatay; 37869052
Aim: We aimed to evaluate the efficacy and safety of graft stent implantation in the endovascular treatment of vascular injuries in the craniocervical area.Materials and methods: This study was carried out through the retrospective screening of eight (two females and six males) patients' records. Patients who used graft stents as an endovascular method were included in the study. The mean age of the patients was 43.6 years (with a range of 15-69 years). Due to different mechanisms, the patients had vascular injuries in the craniocervical region, and graft stent implantation was performed between 2010 and 2022. We evaluated patient demographics, admission symptoms, trauma mechanisms, angiographic findings, treatment modalities and materials, patient outcomes, and follow-up periods.Results: Due to iatrogenesis for four patients, penetrating trauma for three patients, and blunt trauma for one patient, injuries were present in the right internal carotid artery {ICA} (n=1), left ICA (n=1), left common carotid artery {CCA} (n=3), right CCA (n=1), right vertebral artery (n=1), and left vertebral artery (n=1). Angiographically, pseudoaneurysm was detected in seven patients, and vascular rupture was detected in one patient using contrast agent extravasation. All patients who underwent the endovascular method had technical success. Since bleeding from the external carotid artery branches was seen in two patients, these branches were embolized with coils. No radiologically or neurologically pathological findings were recorded during the follow-up period (with a range of one week to 12 years).Conclusion: Graft stent use in the endovascular treatment of craniocervical vascular injuries is an operable, safe, and promising option, especially in patients with pseudoaneurysms and active bleeding.

(2014) Guzelmansur, Ismail; Oguzkurt, Levent; Koca, Nihal; Andic, Cagatay; Gedikoglu, Murat; Ozkan, Ugur; https://orcid.org/0000-0001-8581-8685; 23846579; AAM-1671-2021
Purpose: To retrospectively evaluate the feasibility and effectiveness of endovenous laser ablation or ultrasound-guided foam sclerotherapy for Giacomini vein insufficiency. This is the largest cohort of patients treated for Giacomini vein insufficiency with endovenous laser ablation or ultrasound-guided foam sclerotherapy. Material and methods: Over a three-year period, 23 females and nine males (age range, 19-67 years) treated for Giacomini vein insufficiency with or without saphenous vein insufficiency were retrospectively reviewed. Diagnosis of venous insufficiency was made by color Doppler ultrasonography. Symptomatic insufficiency of the Giacomini vein or the saphenous veins was treated with endovenous laser ablation. Ultrasound-guided foam sclerotherapy was used for tortuous incompetent Giacomini veins. The venous disease was categorized according to the clinical, etiological, anatomical, and pathological classification, and clinical severity was graded with the venous clinical severity score. Follow-up included clinical examination and color Doppler ultrasonography. Results: Thirty-nine limbs in 32 patients were treated (25 endovenous laser ablation and seven ultrasound-guided foam sclerotherapy). All procedures were technically successful. One patient in the ultrasound-guided foam sclerotherapy group had a recurrence with successful repeated treatment. Recurrence was not seen in the endovenous laser ablation group. No complications were observed. All patients had resolution and improvement in 100% of their symptoms at 12 months of follow-up. Conclusion: Giacomini vein insufficiency is mostly seen with insufficiency of the great saphenous vein and can be effectively treated with endovenous laser ablation or ultrasound-guided foam sclerotherapy.

(2021) Dinc, Hasan; Saatci, Isil; Oguz, Sukru; Baltacioglu, Feyyaz; Yildiz, Altan; Donmez, Halil; Belet, Umit; Onal, Baran; Andic, Cagatay; Koc, Osman; Kocak, Omer; Koroglu, Mert; Cetin, Mustafa; Cekirge, H. Saruhan; https://orcid.org/0000-0001-8581-8685; 33392735; AAM-3180-2021
Purpose Our aim was to determine the long-term safety and efficacy of the Flow Re-Direction Endoluminal Device (FRED) in this multicenter study with prospective design. Materials-method This study included 136 consecutive patients with 155 aneurysms treated between March 2013 and June 2016 in 10 centers. Twenty-two (16.2%) patients presented with rupture of the index aneurysm. Large/giant aneurysms comprised 1/3 of the cohort. Adjuvant coil use during the treatment was 15.5%. The effectiveness measure in the study was the percentage of aneurysms with stable occlusion at follow-up. Results Vascular imaging follow-up was performed at least once in 131/136 (96.3%) patients with 148/155 (95.5%) aneurysms up to 75 months (mean: 37.3 months; median: 36 months according to latest follow-up), and 102/155(65.8%) aneurysms in 90/136 (66.2%) patients had >= 24-month control. According to the latest controls, the overall stable occlusion rate was 91.9% (95% CI, 87.5 to 96.3%). Three out of 148 aneurysms with follow-up were retreated (2%, 95% CI 0.0 to 4.3%). Adverse events were noted in 19/136 (14%, 95% CI, 9 to 21%) patients with a morbidity of 1.5% (95% CI, 0.0 to 3.5%). Mortality was 1/136 (0.7%, 95% CI, 0.02 to 2.2%) and was unrelated to aneurysm treatment. In-stent stenosis (ISS) was detected in 10/131 of the patients with follow-up (7.6%, 95% CI; 3.1 to 12.2%), only one being symptomatic. No adverse events have occurred in any of the patients with follow-up after 24 months, except the one resulting from ISS. Conclusion In the treatment of cerebral aneurysms which were candidates for flow diversion technique, this study showed long-term efficacy of FRED with good safety and occlusion rates.

(2014) Coskun, Isa; Demirturk, Orhan Saim; Tunel, Huseyin Ali; Andic, Cagatay; Gulcan, Oner; https://orcid.org/0000-0003-1175-1961; https://orcid.org/0000-0001-8581-8685; 24682572; AAD-5531-2021; AAM-3180-2021
Popliteal artery aneurysms (PAAs) can be treated successfully by surgical and endovascular methods; however, the best treatment strategy for a ruptured PAA has yet to be established. We assessed the clinical results of using saphenous vein interposition to treat ruptured PAAs in our hospital. The subjects of this study were seven men (average age 59 years, range 43-71 years), who underwent emergency surgery for a ruptured PAA at our hospital between January 2007 and November 2012. The patients were assessed after 1, 6, and 12 months, postoperatively. All included patients underwent saphenous vein graft interposition via a medial approach. No complications or graft thromboses were encountered in the immediate postoperative period. The patients were discharged after an average of 4 days postoperatively (range 3-5 days). The patients were followed up for an average of 32 months (range 2-60 months). The medium-term graft patency was 100 %. No patients suffered early or medium-term limb loss and there was no mortality. Based on our positive results, saphenous vein graft interposition should be considered as the first choice of surgical treatment for a ruptured PAA.

(2016) Haydardedeoglu, Filiz Eksi; Torun, Ayse Nur Izol; Andic, Cagatay; Bakiner, Okan; Bozkirli, Emre; kayaselcuk, Fazilet; Ertorer, Melek Eda
Insulinoma is the most common type of islet cell tumor of the pancreas and its incidence is estimated at four per one million persons per year. Although fasting hypoglycemia is the typical presentation, cases with postprandial hypoglycemia have rarely been reported. A 48-year-old woman was admitted to our department for evaluation of hypoglycemia. Laboratory data suggested a state of postprandial endogenous hyperinsulinemic hypoglycemia. Abdominal computed tomography revealed a mass lesion measuring 20 mm at the distal pancreas. A decision was made to perform an arterial calcium-stimulated venous sampling for excluding nesidioblastosis coexisting with a pancreatic incidental mass. After that the patient was referred to surgery. Pathological examination revealed a low-grade well-differentiated neuroendocrine tumor with regional lymph node metastasis. Herein, we report a case of malignant insulinoma presenting with postprandial hypoglycemia and discuss the differential diagnosis and possible mechanisms of postprandial hypoglycemia in insulinoma cases.

(2022) Tanburoglu, Anil; Karluka, Ismail; Mazican, Mustafa; Andic, Cagatay
Purpose: This study aims to evaluate the efficacy and safety of closure of the femoral artery access site using the Angio-Seal Vascular Closure Device in patients who underwent bridging intravenous thrombolytic therapy and subsequent mechanical thrombectomy (MT). Materials and Methods: The retrospective, observational study was performed in patients who were diagnosed with acute ischemic stroke and treated with MT after bridging IVT between September 2018 and September 2021. A total of 97 patients whose femoral artery access sites were closed with Angio-Seal after the procedure was performed were included in the study. Primary demographic data, accompanying risk factors, major and minor complication rates, frequency distributions of categorical variables, and descriptive statistics of quantitative data were calculated and recorded. Results: It was found that 96.9% of the patients did not have major complications, where 97.9% did not have minor complications either. Successful hemostasis was achieved in the groin region in all patients. Major complications observed were recorded as follows: 1 (1%) pseudo-aneurysm, 1 (%) inguinal incision site infection, and 1 (1%) Angio-Seal placement failure. No major complications were observed in 98.2% of those using 6 Fr (French) Angio-Seal and 95.1% of those using 8 Fr Angio-Seal. Conclusion: The findings of the study indicate that Angio-Seal is an effective and safe method for providing groin hemostasis in patients with acute ischemic stroke
Safety and Efficacy of Ventriculostomy Procedures under Dual Antiplatelet Therapy in Patients Treated with Stent Assisted Coiling in Subarachnoid Hemorrhage
(2018) Kardes, Ozgur; Civi, Soner; Suner, Halil Ibrahim; Durdag, Emre; Tufan, Kadir; Andic, Cagatay; Ozmete, Ozlem; 28944945
AIM: Stent assisted coiling (SAC) is an alternative in the treatment of ruptured aneurysms. Stenting requires the use of dual antiplatelet agents. Hydrocephalus is a complication of subarachnoid hemorrhage (SAH) and may require ventriculostomy. Antiplatelet treatment carries a risk of hemorrhage in ventriculostomy. The anti-aggregant effect starts at least four hours after the initial doses of treatment. However, in many studies, ventriculostomy was performed before antiplatelet treatment and hemorrhagic complications were related to the procedure. The aim of this study was to determine the risk of ventriculostomy related hemorrhage in patients with impaired thrombocyte function and to contribute to the literature. MATERIAL and METHODS: Between 2011 and 2016, 53 patients treated with SAC due to SAH in our clinic were retrospectively evaluated. Hemorrhagic complication risks due to antiplatelet therapy related to ventriculostomy were also evaluated. RESULTS: All of the ventricular catheter procedures were performed at least 1 day after the dual therapy (in average 4.3 days after SAC). In 5 patients 1 ventriculostomy was performed, in 2 patients 2, and in 1 patient 6 ventriculostomies were performed. Although radiological hemorrhage was present on the catheter tract in 4 patients, no temporary or permanent neurological deficit was observed. CONCLUSION: Impaired thrombocyte functions pose a risk in ventriculostomy. Also, evaluating the risk of hemorrhage before the antiplatelet treatment reaches its full effect may lead to false results. Studies with small patient groups with anti-aggregant therapy and impaired thrombocyte functions also contribute to the literature. Larger studies regarding this subject are needed.
Successful Retrieval of the Detached Porous Metallic Tip of a Mechanical Aspiration Catheter during Thrombectomy in a Case with May-Thurner Syndrome: A Case Report
(2016) Yavuz, Alpaslan; Andic, Cagatay; Gur, Ali Kemal; Goya, Cemil; Bora, Aydin; Beyazal, Mehmet; 0000-0001-8581-8685; 28031648; AAM-1671-2021; AAM-3180-2021
Modern, minimally invasive techniques used to treat deep venous thrombosis, such as percutaneous mechanical thrombectomy (PMT) and catheter-directed thrombolysis, have gained worldwide acceptance. PMT has the advantage of speed and is also associated with improved outcomes, shortened hospital stays, and low complication rates. The main complications associated with PMT have been primarily due to iatrogenic vascular damage resulting in perforation, embolic occlusion, and arteriovenous fistula formation; to date, there has been no publication in the literature describing complications resulting from device failure. We present an unusual complication of PMT resulting from detachment of the catheter tip during thrombectomy and bailout technique employed.

(2015) Coskun, Isa; Andic, Cagatay; Demirturk, Orhan Saim; Gulcan, Oner
Pseudoaneurysm of the superficial femoral artery after a traumatic fracture of the femur is rarely seen. In the present study, we reported treatment with endovascular embolization and surgery in a 9-year-old male patient in whom superficial femoral artery pseudoaneurysm which developed after traumatic, comminuted femoral distal diaphyseal fracture.
