The patient was therefore diagnosed with a WFNS grade V, Fischer grade 4 subarachnoid hemorrhage, secondary to a ruptured right anterior choroidal artery aneurysm and multiple cerebral blood vessel abnormalities consistent with Moya Moya disease. After discussion with neurosurgery, it was decided that given the inaccessibility of the aneurysm by surgery, it was not unreasonable to perform right anterior choroidal artery occlusion by coiling. Multiple attempts were made at coiling of the right anterior choroidal artery distal aneurysm (supplied by the inferior branch of the anterior choroidal artery). However, due to technical difficulties, the procedure was subsequently aborted. The patient failed to make any significant functional nor neurological recovery, and was palliated in due course.
