Microneurosurgical management of the clinoid and paraclinoid aneurysms
1Department of Neurosurgery, West China Hospital of Sichuan University, Chengdu 610041, China.
Objective:
To evaluate the management of clinoid and paraclinoid aneurysms with modern microneurosurgical techniques and instruments.
Methods:
The data of 38 patients with clinoid and paraclinoid aneurysms who underwent microsurgical clipping in the Department of Neurosurgery, West China Hospital of Sichuan University, Chengdu, China, from 2000 to 2005, were analysed retrospectively.
Results:
All 40 aneurysms were treated microneurosurgically, among which 97.5% were completely obliterated. The overall mortality is 5.2% and 76.3% patients had a good recovery (GOS 4-5) at discharge.
Conclusion:
For patients with clinoid and paraclinoid aneurysms, satisfying outcomes can be achieved by microneurosurgical management, using particular preoperative assessment and planning and careful maneuvering with refined microsurgical instruments. Microneurosurgical techniques are optimal for the management of clinoid and paralinoid aneurysms.
