Abstract:
Objective: To investigate the feasibility of microsurgery in hybrid operation room combined with 3D-DSA in treatment of cerebral aneurysms.
Methods: Fifty-six patients with cerebral aneurysms from February 2015 to December 2016 were retrospectively analyzed. Microsurgery and intra-operation 3D-DSA were carried out in this study.
Results: Among the 56 patients, 3D-DSA showed aneurysm neck clipping and patency of the aneurysm artery in 43 cases (77%) . The residual neck of aneurysm was seen in 9 cases (16%) . After adjusting the clip, 8 cases were successfully clamped, one showed slight residual and no further adjustment was made. Four cases (7%) showed parent artery stenosis. After aneurysm clip adjustment, 2 cases had mild stenosis (lower than 20%) , not adjusted. During the operation, 13 patients (23%) were adjusted by 3D-DSA. One case bled again shortly after the operation and family members gave up. Postoperative intracranial infection occurred in 1 case. During the following 6~12 months, 1 patients died. Cerebral angiography showed no aneurysm recurrence and patency of the aneurysm artery in 55 cases.
Conclusion: The 3D-DSA technique in hybrid operation room can accurately evaluate the morphology and microsurgical clipping effect of the cerebral aneurysm in three-dimensional space, and plays great guidance role in the clipping of cerebral aneurysm.
