    AbstractEfficacy of intravenous systemic thrombolysis is limited in patients with large-vessel occlusion and for whom more than 4.5 hours have passed since onset. As such, mechanical thrombectomy has been the mainstay therapy for these patients. Localization of the intra-arterial clot prior to thrombectomy can be beneficial in cases of acute ischemic stroke. Here, we present 3 cases of acute ischemic stroke that were initially imaged with susceptibility-weighted angiography(SWAN)before endovascular thrombectomy(middle cerebral artery occlusion, internal carotid artery occlusion, basilar artery occlusion)was attempted. In all 3 cases, clot localization by SWAN was consistent with that by angiography, and recanalization was successful. Identifying clot location and composition may help determine the optimal treatment and predict successful recanalization.
