Endovascular treatment of acute ischemic stroke: an Indian experience from a tertiary care center.

BACKGROUND: In India, late presentation due to poor awareness about stroke precludes intravenous thrombolysis (IVT). Endovascular therapy can be used in these circumstances. We present our experience of endovascular treatment of acute ischemic stroke in a tertiary care center. AIM: Endovascular treatment of acute ischemic stroke in a tertiary care center in India. SETTINGS, DESIGN, MATERIALS, AND METHODS: The study period was from 2009 till 2013. Consecutive patients with acute ischemic stroke, who either had contraindications to IVT or had failed IVT, underwent endovascular treatment. Before the publication of interventional management of stroke 3 results, we took a few patients, with large vessel occlusions, directly for endovascular treatment. After imaging, patients were considered for endovascular treatment, using either intra-arterial thrombolysis or mechanical thrombectomy, if there was a documented large vessel occlusion. Outcome was assessed at 3 months using the modified Rankin Scale. STATISTICAL ANALYSIS: Statistical analysis was done using the Statistical Package for the Social Sciences 17.0 software. RESULTS: A total of 45 patients underwent endovascular treatment. The mean age at presentation was 49 years, median National Institutes of Health Stroke Scale (NIHSS) was 19 and the most common site was the middle cerebral artery (23 patients). Solitaire™ stentriever was used in 33 patients. The median pre-procedure Thrombolysis In Myocardial Infarction (TIMI) score was 0 and the median post-procedure TIMI score was 3. Nine patients underwent decompressive craniectomy. On follow-up at 3 months, the median Modified Rankin Scale (mRS) was 0. Eight patients died during 3 months following stroke. CONCLUSION: Endovascular treatment of acute ischemic stroke is a viable treatment option in patients who either have contraindications to IVT or who fail IVT.

Stent-assisted coiling of wide-necked intracranial aneurysms using the Solitaire AB stent.

CONTEXT: Stent-assisted coiling of wide-necked and complex intracranial aneurysms is an effective and feasible treatment option. The self-expanding, fully retrievable Solitaire AB (eV3, Irvine, CA, USA) stent is the latest neurovascular remodeling device available. To the best of our knowledge, there are no studies of Solitaire AB-assisted coiling of wide-necked intracranial aneurysms from India. AIM: Solitaire AB-assisted coiling of wide-necked intracranial aneurysms. MATERIALS AND METHODS: The study was conducted in a tertiary care center with a dedicated Interventional Neurology division from 2009 to 2013. Consecutive patients with wide-necked aneurysms who underwent coiling assisted by the Solitaire AB stent were enrolled in the study. Axium 3D and Helix (eV3, Irvine, CA, USA) platinum coils were used to densely pack the aneurysm sac after deploying the stent across the neck. All patients were pretreated with antiplatelets according to protocol. Subsequently, dual antiplatelets were given for 6 months followed by continued aspirin. Outcome was assessed at 3 months using the modified Rankin Scale. STATISTICAL ANALYSIS USED: Statistical analysis was done using the SPSS 17.0 software. RESULTS: A total of 16 patients underwent stent-assisted coiling. The most common site was the internal carotid artery (nine patients), median aneurysm size was 7 mm and median neck diameter was 5 mm. Thirteen patients presented with ruptured aneurysms. We achieved complete occlusion in all patients with no major complications. Thirteen patients were followed up, all have an mRS score of zero or one. CONCLUSION: We conclude that for wide-necked aneurysms, stent-assisted coiling using the Solitaire AB is a safe and effective treatment option.
