Acute ischemic stroke patients without angiographically revealed arterial occlusion / 介入放射学杂志

ABSTRACT

Approximately 20%-30% of the patients with acute ischemic stroke do not have an angiographically demonstrable arterial occlusion. This article reviews the possible explanations for the absence of angiographically documented occlusion, the risk and the occurrence rate of cerebral infarction, the prognosis, and the effectiveness as well as the safety of thrombolytic therapy.
