Abstract

OBJECTIVE
We present a clinical analysis to envision the difficulties in supraclinoid internal carotid artery(ICA) aneurysmal neck clippings to improve the postoperative outcome.
METHODS
Two hundred and fifty aneurysm surgeries were undertaken at our hospital from 1997 to 1998. There were 52 patients(20.4% of the total) of supraclinoid ICA saccular aneurysmal patients. Eighteen cases(34.6%) were found with diverse difficulties in direct neck clippings. The authors analyzed the causes of surgical difficulties in the clipping on supraclinoid ICA aneurysms, in a clinical perspective.
RESULTS
Perfect aneurysmal clippings were performed in 45 patients(86.5%) of the total 52 cases of supraclinoid ICA aneurysms. The clipping and wrapping were needed in five cases(9.6%), trapping in one(1.9%) with one case(1.9%) needed only for wrapping. The causes of difficulties in direct neck clipings were : aneurysm sac involving perforator in six cases(11.5%), too short an ICA proximal to posterior communicating artery for temporary clipping in 5(9.6%), posterior communicating artery aneurysm directed to the ventral side in three(5.8%), dorsal wall aneurysm in one, severe atheromatous ICA in one, a larger sac than in angiographic finding with partial thrombosis in one, severe adhesion of aneurysm to 3rd cranial nerve in one patient.
CONCLUSION
For supraclinoid ICA aneurysm surgery, sufficient preoperative plans and careful inspection including angiographic findings to foresee the various difficulties of neck clippings are needed.
