| ABSTRACT |
|
The authors report two cases of intracranial aneurysm associated with aplasia of internal carotid artery. The one case showed complete occlusion of left internal carotid artery just above the origin of ophthalmic artery and aneurysm which located at the junction of basilar-superior cerebellar artery. The blood supply of the left side of anterior cerebral came from the right carotid artery through the anterior communicating artery and the left middle cerebral artery came from basilar artery through the enlarged posterior communicating artery. The another case showed marked narrow cervical portion of right internal carotid artery which terminated as a posterior communicating artery just above the origin of ophthalmic artery and large aneurysm which located at the anterior communicating artery.
The blood supply of the right side of anterior cerebral and middle cerebral artery came from the left internal carotid artery through the anterior communicating artery. We tried to surgical management of these two aneurysms. We reviewed the literature and discussed the related collateral circulation of this anomaly. |
