作者对225例脑外基底中部肿瘤手术患者研究其术后早期大脑前动脉(ПМА)区血循环障碍的主要临床表现。男104例、女151例,年龄16～74岁,并对其中24例死亡者进行了形态学研究。根据术后临床过程、电子计算机X 线断层扫描(KT)和形态学,将其术后早期ПМА区血循环障碍分为3型:皮质下一间脑型,皮质下—内囊型和额—胼胝体型。1.皮质下—脑型(16例):结果均死亡。由ПМА起始部(A_1)与前交通动脉区缺血性障碍所致。该综合征是因肿瘤(蝶鞍旁脑膜瘤4例,垂体腺瘤5例,颅咽管瘤7例)向蝶鞍前扩展而致手术损害了丘脑下部结构和皮质下结节前内侧部所造成。通常在手术分离动脉环前部肿瘤时伴随出血发生
The authors studied the main clinical manifestations of 225 cases of patients with central extracranial basilar tumors who had circulatory disturbances in the early postoperative anterior cerebral artery (PLМА) region. There were 104 males and 151 females, aged 16 to 74 years, and 24 of them were morphologically studied. According to the postoperative clinical course, computerized tomography (KT) and morphology, the circulatory disorders in the early postoperative period in the ПМА area were divided into 3 types: a subcortical brain type, subcortical-inner sac type, and fronto-temporal body. type. 1. Subcortical-brain type (16 cases): All died. It is caused by an ischemic disorder in the anterior communicating artery region of the primo section (A_1) of ПМА. The syndrome was caused by a tumor (parasellar meningioma 4 cases, pituitary adenoma 5 cases, craniopharyngiomas 7 cases) extended to the front of the sella resulting in damage to the hypothalamic structure and the anterior medial side of the subcortical nodule. Caused. It usually occurs with hemorrhage when surgically separating the anterior ring of the annulus
