    Abstract:
    OBJECTIVE: To discuss the surgical treatment of the giant aneurysms of middle cerebral artery. METHODS: Clinical data, surgical methods and outcomes were analyzed in 17 giant aneurysms of middle cerebral artery treated from January 2001 to March 2008. CT scan, CTA, MRA, DSA and 3D-DSA were performed before operations so that we could comprehend the location, size, and shape of aneurysms and compensatory circulation of collateral branches to design the individualized treatment options. All patients had been surgically treated mostly by modified pterional approach, of which, direct clipping of the aneurysms was accomplished in 4 patients, aneurysms trapping or removal after trapping in 4, aneurysms excision or trapping combined with vessels reconstruction in 7, and aneurysms wrapping in 2 cases. RESULTS: CT and MRI revealed the shape and size of aneurysms clearly, while DSA and 3D-DSA could demonstrate the aneurysm's neck and relationship with the adjacent structure. Postoperative neurological function was evaluated according to Glasgow Outcome Scale when patients were discharged. Twelve patients had excellent neurological outcomes. However 4 patients were moderately disabled and one were severely disabled. No patient was dead postoperatively. CONCLUSIONS: It is necessary to perform elaborate imaging before operations for individualized surgical planning. The temporary occlusion of the parent artery and elimination of intra-aneurysmal thrombus are helpful to clipping the aneurysmal neck. Vessels reconstruction is a new and effective method of treating the giant aneurysms of middle cerebral artery.
