    Does Stroke Etiology Play A Role in Predicting Outcome of Acute Stroke Patients Who Underwent Endovascular Treatment With Stent Retrievers?
    (2017) Giray, Semih; Ozdemir, Ozcan; Bas, Demet F.; Inanc, Yusuf; Arlier, Zulfikar; Kocaturk, Ozcan; 28017193
    Aims: The goal of the study was to identify whether the stroke etiology play a role in the recanalization and outcome of patients who underwent mechanical thrombectomy with stent retrievers. Methods and results: A retrospective analysis of a prospectively collected database included consecutive patients treated with stent retrievers. We included patients with cardioembolic stroke and large vessel atherosclerotic disease and compared risk factors for stroke, baseline NIHSS and Alberta Stroke Program Early CT scores (ASPECTS), stroke outcome, recanalization rate, onset-to-recanalization, onset-to-groin puncture time and the procedural time between two groups. Male sex was statistically more common in patients with large vessel atherosclerotic disease. Mean time from symptom onset- to the achievement of recanalization in patients with LVAD was 242 +/- 72.4 compared with cardioembolic stroke patients (301 +/- 70.7; p = 0.014). Time for groin puncture to recanalization was longer in patients with cardioembolic stroke compared to LVAD group (97.5 +/- 44.3 vs 58.2 +/- 21.8; p = 0.002). Time for microcatheter to successful recanalization or procedural termination was longer in patients with cardioembolic stroke compared to LVAD group (63.6 +/- 30.2 vs 34.2 +/- 19.4; p < 0.001) with cardioembolic stroke had significantly worse long-term outcome (mRS 3-6) compared to those with LVAD (60.6% vs 26.3%; p = 0.036). Conclusion: Stroke etiology may play a role in the outcome of acute stroke patients who underwent endovascular stroke therapy. Cardioembolic strokes may be more resistant to endovascular acute stroke treatment. (C) 2016 Elsevier B.V. All rights reserved.

    Endovascular Recanalization of Thromboangiitis Obliterans (Buerger's Disease) in Twenty-Eight Consecutive Patients and Combined Antegrade-Retrograde Intervention in Eight Patients
    (2019) Firat, Ali; Igus, Behlul; 0000-0003-3296-7227; 30834476
    PurposeThe aim of the study was to evaluate the technical success of the procedure and the clinical efficacy of treatment in patients with thromboangiitis obliterans (TAO) (Buerger's disease) based on a change in the Rutherford classification.Materials and MethodsA total of 28 consecutive patients (26 males, 2 females, mean age 43.35.32years) underwent endovascular recanalization with a diagnosis of TAO, between April 2015 and July 2018. After unsuccessful attempts using the antegrade approach, retrograde approaches were used in 8 patients under ultrasound guidance. Clinical follow-up was routinely performed at 1-month, 3-month, 6-month, and 1-year intervals.ResultsA total of 28 TAO patients underwent 40 procedures in 32 limbs. Technical success was achieved in 28 of the 32 limbs (87.5%). In total, 45 of 59 (76.2%) below the knee arteries were treated successfully. One major amputation was performed, providing a 96.8% rate for limb salvage both at 12 and 24months. Amputation-free survival estimated by Kaplan-Meier analysis was 84% at 12 and 24months. Primary patency rates at 12, 24, and 36months were 84%, 78%, and 75%, respectively. Secondary patency rates were 87.5% both at 12 and 24months.Conclusionp id=ParEndovascular treatment is a technically feasible and potentially effective treatment modality for Buerger's disease. Combined antegrade and retrograde interventions in TAO patients may improve technical success and clinical recovery, especially in cases where the antegrade approach has failed.

    The Efficacy of Flow Diverter Stents in the Treatment of Wide-Necked Intracranial Aneurysms
    (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.
