We investigated the current status of reperfusion therapies for acute ischemic stroke in the Kyushu and Okinawa districts employing a questionnaire. Among 195 neurological or neurosurgical institutions, 117 (60.0%) submitted replies to the questionnaire. Of these 117 institutions, 109 had conducted some treatments for acute ischemic stroke and were enrolled in the present study. Examinations for site of occlusion in the acute stroke patients without any abnormality on computed tomography (CT) were performed in 67.0% of the institutions. mainly by digital subtraction angiography (DSA) or magnetic resonance angiography (MRA) . The use of ultrasonography (US) and CT angiography (CTA) was less frequent (in only 20-30% of the institutions). Reperfusion therapies were performed in only 58.7% of the institutions. In 53.3% of the neurological and 28.1% of the neurosurgical institutions, no reperfusion therapies were considered at all Among the various reperfusion therapies intravenous urokinase infusion was the most widely employed therapy (51.6%). Intraarterial local and regional thrombolysis was performed in 50.0% and 46.9% of the institutions respectively.
