目的探讨三维血管成像在老年脑膜瘤手术切除计划中的应用价值。资料与方法对实施次全切手术的12例老年性脑膜瘤血管成像特点进行回顾性分析。结果 12例患者通过三维血管成像模拟操作早期制定次全切手术方案,其中3例瘤体基底较宽,单纯入路难以顾及入路远侧结构,2例瘤体深度包裹颅内重要动脉,3例侵及脑干或脑实质(功能区),2例瘤体位置较深,颅内重要血管阻碍手术操作窗,2例窦旁脑膜瘤静脉窦部分被侵犯,侧支循环通路建立不完善,术中所见与三维血管成像图像高度一致,术后一致认为手术计划合理。结论应用三维血管成像技术对老年脑膜瘤患者进行术前风险度评估,能帮助临床制定合理的手术方案,从而降低手术创伤及并发症,改善患者预后。
Objective To investigate the value of three-dimensional angiography in the surgical resection of meningioma in the elderly. Materials and Methods Retrospective analysis of angiographic features of 12 cases of senile meningioma underwent subtotal resection. Results In the 12 patients, subtotal surgical resection was made by three-dimensional angiography. Three of the tumors had a wide basement, difficult access to the distal structure, two deep intracranial aneurysms, and 3 Cases of invasion and brainstem or brain parenchyma (functional area), 2 cases of deep tumor location, intracranial important blood vessels hinder the operation of the window, 2 cases of sinus venous sinus were partially infracted, the establishment of collateral circulation imperfect, Intraoperative findings and three-dimensional angiography images are highly consistent, after surgery agreed that the surgical plan is reasonable. Conclusion The application of 3-D angiography in the evaluation of preoperative risk of elderly patients with meningioma can help to make a reasonable surgical plan to reduce the surgical trauma and complications and improve the prognosis of patients.
