Recanalization of Cerebral Arterial Occlusion Just Before Emergent Angiography

초록

Purpose : After development of stent retrieval system, mechanical thrombectomy is considered to the patients with hyperacute ischemic stroke caused by major cerebral artery occlusion with DWIPWI mismatch, which is usually identified on MR or CT scans. Sometimes, spontaneous recanalization is observed on emergent conventional angiography, which did not need further intervention. However, characteristics of recanalization in hyperacute period remained unknown. Here, we investigated the predictors for recanalization of cerebral arterial occlusion just before conventional angiography and outcomes of these cases.
