Long-Term Follow-Up for a Giant Basilar Trunk Aneurysm Surgically Treated by Proximal Occlusion and External Carotid Artery to Posterior Cerebral Artery Bypass Using a Saphenous Vein Graft

The authors describe a case of a basilar trunk aneurysm with long-term follow-up after successful bypass and proximal occlusion. A 64-year-old woman had a giant aneurysm of the basilar trunk and underwent external carotid artery-to-posterior cerebral artery vein graft bypass surgery and proximal cli...

Description
Summary:The authors describe a case of a basilar trunk aneurysm with long-term follow-up after successful bypass and proximal occlusion. A 64-year-old woman had a giant aneurysm of the basilar trunk and underwent external carotid artery-to-posterior cerebral artery vein graft bypass surgery and proximal clipping of the basilar artery, which was followed by low-dose aspirin (100 mg/d) treatment. No ischemic symptoms and lesions developed and the thrombosed aneurysm was stable during 11 years of follow-up. An extracranial–intracranial high flow bypass combined with immediate proximal occlusion and aspirin administration may be an acceptable treatment option for patients with giant posterior circulation aneurysms.
