椎-基底动脉供血不足70例临床分析

摘要

目的：探讨椎-基底动脉供血不足(VBI)的临床特点。方法：分析70例VBI患者临床表现、重要辅助检查、治疗及转归。结果：VBI多发生于40～60岁的中老年人，起病急，病程1 d～20年，头位或／和体位突然转动是主要诱因，颈椎增生改变是主要发病原因，血液动力学、神经电生理检查能大大提高临床确诊率，血液生化学及影像学检查有助于病因诊断并指导治疗。结论：VBI是多种因素引起的供血代偿不全或完全不能代偿所致，多因头、体位突然改变而诱发，本病治疗效果较好，预防发作是治疗的关键。%Objective:To investigate the clinical features of vertebrobasilar ischemia(VBI). Methods:To analyze the clinical findings, accessory examination, treatment and outcome of 70 patients with VBI. Results: VBI occurred more often in patients aged between 40and 60 with a sudden onset and time course ranging from 1 day to 20 years. Abrupt change ofthe head and/or body position was the main predisposing cause. Cervical hyperplasia was thechief pathogenic factor. Examinations of hemodynamics and neuroelectrophysiology greatly improved the rate of clinical diagnosis. Blood biochemical tests and imaging examination helpedthe pathogenetic diagnosis and guided the treatment. Conclusion :VBI is caused by insufficiency or non-compensation of blood supply caused by various factors, and often induced by abruptchange of the head and body position. It responds well to treatment. Prevention is a key to treat-ment.
