The clinical value of three-dimensional CT angiography(3D-CTA) in the diagnosis and treatment of intracranial the rupture middle cerebral artery aneurysm

Objective To study the clinical value of three-dimensional CT angiography(3D-CTA) in the diagnosis and treatment of intracranial the ruptured middle cerebral artery aneurysm(MCAA).Methods From January 2010 to December 2011,a retrospective study was performed on 122 patients with spontaneous subarachnoid hemorrhage with 18 middle cerebral artery aneurysms.All the patients were examined by 3D-CTA before operation and surgical simulation was conducted.17 middle cerebral artery aneurysms were clipped by pterional approach microsurgical surgery and compared preoperative 3D-CTA imaging data.Results Preoperative diagnosis by 3D-CTA in different location of middle cerebral artery aneurysms had seen exactly the same with intraoperation.In addition to a fusiform aneurysm of M2 middle cerebral artery was wrapped,the remaining 17 aneurysms were successful clipping.16 patients of good recovery after operation.One patient due to preoperative Hunt-Hess scores Ⅴ grade and he died of bilateral hernia after operation.One patient admitted to hospital in preparation to operate before the second hemorrhage,The patients could not be self-reliant life after emergency surgery.Conclusion 3D-CTA can diagnose and simulate surgery to different location ruptured the middle cerebral artery aneurysm.It can provide good value for successful clipping surgery of middle cerebral artery aneurysm.
