Case of Subarachnoid Hemorrhage from Ruptured Oncotic Fusiform Aneurysms from Choriocarcinoma Metastasis Treated with Aneurysmectomy and Vessel Reconstruction

Aneurysmectomy, resection of the parent artery with irregular walls and reconstruction to the distal recipient artery with normal intima should be considered to secure patency of the anastomosis and prevent the recurrence of oncotic aneurysm. Subsequent chemotherapy is essential to prevent carcinomatous meningitis and disease progression.
