Abstract

Background: Severely impaired patients with persisting intracranial occlusion despite standard treatment with intravenous (IV) administration of recombinant tissue plasminogen activator (rtPA) or presenting beyond the therapeutic window for IV rtPA may be candidates for interventional neurothrombectomy (NT). The safety and efficacy of NT by the Penumbra System (PS) were compared with standard IV rtPA treatment in patients with severe acute ischemic stroke (AIS) caused by large intracranial vessel occlusion in the anterior circulation. Methods: Consecutive AIS patients underwent a predefined treatment algorithm based on arrival time, stroke severity as measured by the National Institutes of Health Stroke Scale (NIHSS) score, and site of arterial occlusion on computed tomographic angiography (CTA). NT was performed either after a standard dose of IV rtPA (bridging therapy [BT]) or as single treatment (stand-alone NT [SAT]). Rates of recanalization, symptomatic intracranial bleeding (SIB), mortality, and functional outcome in NT patients were compared with a historical cohort of IV rtPA treated patients (i.e., controls). Three-month favourable outcome was defined as a modified Rankin Scale (mRS) score ≤2. Results: Forty-six AIS patients were treated with NT and 51 with IV rtPA. The 2 groups did not differ with regard to demographics, onset NIHSS score (18.5 ± 4 v 17 ± 5; P =.06), or site of intracranial occlusion. Onset-to-treatment time in the NT and IV rtPA groups was 230 minutes (±78) and 176.5 (±44) minutes, respectively (P =.001). NT patients had significantly higher percentages of major improvement (≥8 points NIHSS score change at 24 hours; 26% v 10%; P =.03) and partial/complete recanalization (93.5% v 45%; P
