目的 :探讨蛛网膜下腔出血 (SAH)导致症状性脑血管痉挛的原因、发病机制及治疗原则。方法 :对 2 6例因SAH出现症状性脑血管痉挛 (DIND)的病人进行头颅CT检查、血中凝血因子以及颅内MRA检查 ,对病人应用扩血管药物的同时加以稀释血液的扩容疗法。结果 :2 6例病人中 18例综合治疗后脑缺血症状完全消失。结论 :症状性脑血管痉挛的发生不仅仅是脑血管痉挛加重的结果 ,而病人凝血机制异常即处于高凝状态是发病的重要原因
Objective: To investigate the causes, pathogenesis and treatment of symptomatic cerebral vasospasm caused by subarachnoid hemorrhage (SAH). Methods: Twenty - six patients with symptomatic cerebral vasospasm (SAH) who had symptomatic cerebral vasospasm (SAH) underwent head CT examination, blood coagulation factors and intracranial MRA examination. The patients were treated with vasodilator drugs while diluted blood was dilated. Results: The symptoms of cerebral ischemia completely disappeared in 18 of 26 patients after comprehensive treatment. Conclusion: The occurrence of symptomatic cerebral vasospasm is not only the result of aggravation of cerebral vasospasm, but also the abnormal coagulation mechanism in patients with hypercoagulable state is the important cause of the disease
