CT perfusion-guided endovascular treatment of symptomatic cerebral vasospasm in a patient with perimesencephalic non-aneurysmal subarachnoid hemorrhage

Abstract

Symptomatic vasospasm represents an uncommon complication of perimesencephalic nonaneurysmal subarachnoid hemorrhage (SAH) which is a benign form of SAH without any recognizable source of bleeding accounting for about 15% of non-traumatic SAH [1,2].
