Application of 3D–DSA simulated surgical path in intracranial aneurysm clipping surgery

Background: Intracranial aneurysm is a common cerebrovascular disease, which cause wide concern by neurosurgeons. The 3D–DSA images simulated surgical path may improve the success rate of operation in bridging surgery of emergency ruptured intracranial aneurysms. Methods: Eighteen patients with intracranial ruptured aneurysms that underwent craniotomy clipping surgery from January 2015 to January 2016 were included in this study. All patients were diagnosed with ruptured aneurysm and SAH, and 3 of them had concomitant hematoma. All patients were clipped in 3 days after diagnosis. Before clipping, the relevant information and data of the 3D–DSA images simulated surgical path were observed to guide intracranial aneurysm clipping surgery. Results: According to the information of the 3D–DSA images simulated surgical path, all aneurysms were clipped successfully. 1 patient died of vessel spasm, and the remaining patients recovered well. Conclusions: The 3D–DSA images simulated surgical path could provide surgeons with a lot of information in bridging surgery of emergency ruptured intracranial aneurysms,and is significant to improve the success rate of operation.
