目的 探讨中、后部矢状窦旁脑膜瘤导致静脉窦闭塞后静脉代偿特点以及全切除肿瘤的手术要点。方法 分析 15例中、后部上矢状窦完全闭塞的窦旁脑膜瘤的脑血管造影表现 ,探讨其静脉回流代偿的形式对手术疗效的影响。结果 静脉回流代偿的形式有三种 :( 1)皮层浅静脉端 端吻合 ,主要流向侧裂、Labbe静脉 ;( 2 )脑膜静脉流向蝶顶窦、海绵窦 ;( 3)板障静脉流向头皮。本组肿瘤全切除 12例 ,无手术死亡 ,术后发生三肢瘫 1例 ,双下肢瘫 1例 ,高颅压、失明 1例。结论 术前仔细研究血管造影上静脉回流代偿的形式 ,有助于术中加强对其保护 ,减少全切除肿瘤手术后的严重并发症的发生。
Objective To investigate the characteristics of venous compensations caused by sinotial sinus meningioma in the posterior sagittal sinus and the main points of surgical resection of the tumor. Methods The cerebral angiography of 15 cases with complete occlusion of the superior sagittal sinus in the middle and posterior part of the sinus were studied. The effects of venous return compensated form on the curative effect were analyzed. Results There were three forms of compensatory venous return: (1) anastomosis of the superficial cortical veins, mainly to the lateral fissure, Labbe vein; (2) the meningeal vein to the apical sinus and cavernous sinus; (3) the baffle vein to the scalp. The group of tumor resection in 12 cases, no operative death, postoperative paralysis of three cases occurred in one case, double lower limb paralysis in 1 case, high intracranial pressure, blindness in 1 case. Conclusions Careful study of the venous return compensatory form before angiography helps to strengthen its protection during operation and reduce the incidence of serious complications after total resection of the tumor.
