Abstract:
OBJECTIVE:To determine the role of 3-dimensional computed tomograph angiography (3D-CTA) and neuroendoscope in intracranial aneurysm, and to analyze its benefits.
METHODS:A total of 38 patients with intracranial aneurysm were confirmed by operation. All the patients were examined by 3D-CTA before the operation and surgical simulation was conducted to ensure the location of aneurysm and its relationship with parent aneurysm artery. Endoscopy was used as an adjunct before and after the microsurgical treatment to observe the neck anatomic features and perforating branches and to verify the optimal clipping position.
RESULTS:Pre-operative 3D-CTA clearly displayed the aneurysm and their relation with the parent aneurysm artery, the aneurysm, the periphery vessel, and bony structures, according to demonstration during the operation. Endoscope clearly showed the anatomy around aneurysm, especially the perforating branches. Postoperative 3D-CTA showed satisfactory aneurysm clipping.
CONCLUSION:Simulation surgery of 3D-CTA is helpful in finding and exposing aneurysm. Neuroendoscope is very useful for protecting deep blood vessels. Combination of the two can increase the operation success ratio and reduce postoperative complications.
