Abstract
Background and Purpose— Intraarterial and intravenous thrombolysis are often ineffective for the treatment of acute ischemic stroke and are associated with a significant risk of intracranial hemorrhage (ICH). Multimodal rescue therapy combining mechanical disruption and platelet GPIIb/IIIa receptor antagonists may improve recanalization. Methods— Patients who did not recanalize with thrombolysis were treated with GPIIb/IIIa antagonists, angioplasty, or an embolectomy device. Treatment was individualized based on vascular anatomy, stroke mechanism, patient status, and symptom duration. Results— Twelve patients were treated within 3.8±2.2 hours. The mean National Institutes of Health Stroke Scale (NIHSS) score was 19.4±4.1. Six patients had carotid terminus occlusion, whereas 5 had middle cerebral artery and 1 had basilar artery occlusion. The average doses of intraarterial tPA and reteplase were 17.1±8.6 mg and 2±0.6 units, respectively. All patients received either an intravenous or intraarterial abcixima...
