Intracranial traumatic aneurysms are one of the importment post-traumatic sequelaes. In our department we have had ten cases of intracranial traumatic aneurysm and seven cases were operated upon. The location of the aneurysms were anterior cerebral artery in four cases, middle cerebral artery in two cases and supraclinoid internal carotid artery in one case. The operative methods were trapping in five cases, neck ligation in one case, resection and neck suture in one case. Three cases had severe intraoperative rupture of the aneurysm. In all cases temporary occlusion of the parent artery and administration of mannitol were used. Operative methods and approach of these cases are discussed in this paper. Results of the seven cases were good in five and fair in two. Histological findings of aneurysmal wall were pseudoaneurysm in six cases.
Since the wall and neck of traumatic aneurysms are fragile and the danger of intraoperative rupture is very high, it is considered to be safer to occlude the parent artery temporally. Trapping and revascularization surgery before disclosing the aneurysm neck are often needed.
