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.
Real World Data Estimation: Management and Cost-analysis of Stroke in Tertiary Hospitals in Turkey and the Impact of Co-morbid Malnutrition

Objective: To evaluate the management and cost analysis of first-ever stroke patients in Turkey and determine the impact of comorbid malnutrition. Methods: This study was based on expert's view on the management and cost analysis of stroke patients with or without malnutrition via standardized questionnaire forms filled by experts according to their daily clinical practice. Cost items were related to medical treatment, healthcare resources utilization, tests, consultations and complications. Per admission and total annual direct medical costs were calculated with respect to co-morbid malnutrition. Results: Malnutrition was evident in 7.8(3.6)% [mean(standard error of mean; SEM)] of patients at admission; an additional 7.1(4.8)% and 0.9(0.6)% patients developed malnutrition during Neuro-ICU and stroke unit hospitalization, respectively. Length of hospital stay (LOS) was almost 2-fold in patients with malnutrition (P<0.01 for all hospital units). During the 1-year follow-up period a mean(SEM) of 93.8(15.4)% with and 43.3(3.7)% without malnutrition were expected to experience at least 1 complication. The mean (SEM) per patient annual cost of stroke was US$5201(740) in patients with malnutrition and US$3619(614) in patients without malnutrition, while the corresponding figures for per admission were US$3061(513) and US$1958(372), respectively. Conclusions: In conclusion, our findings revealed that management of stroke and its complications have a relatively high burden on the Turkish health reimbursement system. Furthermore, co-morbid malnutrition, being not uncommonly encountered, increased the overall costs and was associated with longer LOS and higher rate of expected complications during 1-year follow up.
