OUTCOME AND SAFETY OF RECANALIZATION TREATMENTS IN ISCHEMIC STROKE DUE TO ACUTE BASILAR ARTERY OCCLUSION

Study Overview
=================
Brief Summary
-----------------
Rationale: Recently, two prospective multicenter RCT reported a potential beneficial effect of endovascular thrombectomy (EVT) in patients with an acute symptomatic basilar artery occlusion (BAO). However, the high rate of crossover in BEST study and the long-term of recruitment in BASICS study influenced the validity of the results. Objective: To assess the outcomes and prognostic factors of recanalization therapy in patients with BAO, caused by a CTA/MRA/DSA confirmed occlusion of the basilar artery. Study design: This is a prospective observational study. Study population: Patients with acute ischemic stroke and a confirmed basilar artery occlusion by CTA/MRA/DSA. Main study parameters/outcomes: Favorable outcome at day 90 defined as a modified Rankin Score (mRS - functional scale) of 0-3. The estimate will be adjusted for the known prognostic variables age, time from onset to treatment, stroke severity (NIHSS), PC ASPECT and collateral flow and adjusted and unadjusted estimates with corresponding 95% confidence intervals will be reported.

Detailed Description
-----------------
Acute basilar artery thrombosis is associated with a poor prognosis. Prevalence of basilar artery occlusion are not known in Vietnam.Various treatments were tried in groups of patients with acute ischemic stroke due to basilar artery occlusion, but evidence based was not cleared previous studies. Therefore, we conduct this study to evaluate the efficacy and safety of recanalization therapies, which included intravenous thrombosis alone, endovascular alone, or bridging IVT and endovascular, in basilar artery occlusion stroke patients.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| favourable outcome | a modified Rankin Score of 0-3 | 90 (± 14 days) after procedure | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| good outcome | a modified Rankin Score of 0-2 | 90 (± 14 days) after procedure | 
| mortality | Number of subjects who died at 90-day follow-up/total number of subjects who participated in 90-day follow-up) x100%. | 90 (± 14 days) after procedure | 
| Dichotomized mRS score | mRS (0-2 versus 3-6 and 0-4 versus 5-6 ) | 90 (± 14 days) after procedure | 
| Symptomatic intracerebral hemorrhage (sICH) | SICH means any hemorrhage with neurological deterioration, as indicated by an NIHSS score that was higher by ≥4 points than the value at baseline or the lowest value in the first 72 hours or any hemorrhage leading to death. | within 72 hours after procedure | 
| Any intracerebral hemorrhage | intracerebral hemorrhage was defined according ECASS definition. | within 72 hours after procedure | 
| Procedural related complications | arterial perforation, arterial dissection, embolization in a previously uninvolved vascular territory and so on | Perioperative period |
