Abstract
✓ The author presents the case of a patient with a ruptured vertebral artery dissecting aneurysm in which the posterior inferior cerebellar artery (PICA) arose from the wall of the aneurysm. The aneurysm was treated by trapping and the PICA was anastomosed to the vertebral artery proximal to the dissection. This technique allows intraoperative obliteration of the aneurysm while maintaining normal blood flow to the PICA.
