Objective:
To summarize the experience of surgical therapy in a series of 438 patients with intracranial aneurysms.
Methods:
A retrospective analysis was made on the clinical data of 438 patients, in terms of the perioperative management, timing of surgery, surgical skills, and The HUNT-HESS grade.
Results:
438 patients with 476 aneurysms underwent microsurgery, in which 450 aneurysms were clipped, 14 were wrapped, 8 were isolated,4 were cut. 32 aneurysms were ruptured (6.72%) during the operation. The relation between Hunt-Hess scale and mortality is significant postpone operation (> or =7 d) has got a better curative effect than the early.
Conclusions:
Microsurgical treatment is a confirmed effective method with intracranial aneurysms. The higher of HUNT-HESS grade will result to the worse clinical outcome.
