Persistent primitive trigeminal artery is relatively rare cerebrovascular anomaly, usually observed on angiography or at autopsy. We reported two cases of persistent primitive trigeminal artery. One is associated with spontaneous subarachnoid hemorrhage and the other intraventricular hemorrhage with scanty subarachnoid hemorrhage after minor head trauma. We reviewed the persistent primitive trigeminal artery and it's clinical significance. It's clinical significance seemed to be followed; 1) Formation of intracranial aneurysm due to increased arterial blood flow. 2) pathway for microemboli from carotid system to basilar system. 3) probable cause hemodynamic cerebral ischemia. 4) unexpected finding during surgical procedure.
Key Words: Persistent primitive trigeminal artery; Gasserian ganglion; Subarachnoid hemorrhage; Aneurysm
