title: [Two cases of persistent primitive artery associated with anterior communicating aneurysm].
abstract: Two aneurysm patients who have persistent primitive artery are reported. Both patients were admitted to our hospital under the diagnosis of subarachnoid hemorrhage. Carotid angiograms revealed saccular aneurysms in the anterior communicating artery. One case had the right persistent trigeminal and the other had the right persistent hypoglossal artery. Both patients were treated by aneurysmal neck clipping successfully. The incidence of association of persistent primitive trigeminal artery with intracranial vascular disease is 25%, in which 14% of cases have the intracranial aneurysms. Other congenital anomalies of the intracranial artery co-existent with intracranial aneurysm have been considerably reported so far. Our cases might suggest that congenital factors have taken part in the formation of the intracranial aneurysm.
