Ruptured distal anterior choroidal artery aneurysm presenting with right intracerebral haematoma: clipping aided by subpial uncal resection.

Abstract

This report describes a rare case of a distal right anterior choroidal artery aneurysm which developed a right intracerebral haematoma and intraventricular haemorrhage and was treated by surgical exploration and clipping with the aid of a limited subpial resection of the uncus and ambient gyrus. The technique of limited subpial uncal resection allows the surgeon to follow the anterior choroidal artery without much difficulty, achieves proximal control early and aids in the eventual clipping procedure.
