Rupture of a Left Posterior Inferior Cerebellar Artery Aneurysm with a Vertebral Artery Originating from the Aorta.

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.

[Significance of susceptibility-weighted angiography for endovascular thrombectomy of acute ischemic stroke].

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.
