ABSTRACT
Objective: Cerebral aneurysms (ANs) in the cortical segment (CS) of the distal posterior inferior cerebellar artery (PICA) with a vertebral artery (VA) of aortic origin are markedly rare. Endovascular therapy was performed to treat subarachnoid hemorrhage caused by a ruptured cerebral AN. Case Presentation: The patient was a 68-year-old female who was transported to emergency care for headache. Detailed examination revealed an AN in the CS of the PICA with a left VA of distal aortic origin from the left subclavian artery (LT. SA). Endovascular therapy using n-butyl-2-cyanoacrylate (NBCA) was performed to treat the cerebral AN, resulting in a favorable outcome. Conclusion: Endovascular therapy for cerebral ANs is an effective treatment method.
ABSTRACT
Efficacy 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.
