title: Parent artery occlusion for posterior cerebral artery aneurysms.
abstract: We review four cases of posterior cerebral artery (PCA) aneurysm, of which three showed intolerance of parent artery occlusion. In two, balloon test occlusion (BTO) indicated poor opacification of the PCA branches from the anastomoses, and therefore, permanent occlusion was not attempted.
