Microsurgery for Complex Intracranial Aneurysms

Objective To analyse the experience and lesson of microsurgery for the complex intracranial aneurysms in rent five years. Methods Of 47 patients with complex intracranial aneurysms, 37 were treated by microsurgically clipping the aneurysmal necks, 5 by aneurysms trapping followed extracranial and intracranial arteries bypass, 4 by reconstructing the parent arteries followed resection of the aneurysms and 1 by coating the aneurysm. Results The prognoses of all the patients were evaluated by Glasgow outcome scale (GOS). Of 47 patients, 35 were recovered well, 6 moderately disabled, 2 several disabled and 4 died. Conclusions The treatment of complex aneurysms is still a challenge to microneurosurgery. The proper method should be selected for individual case.
