摘要
目的 探讨全脑血管造影阴性的蛛网膜下腔出血(SAH)的病因学特点及临床处理方法。方法 对1993～1998年50例全脑血管造影阴性患者的诊断、治疗进行回顾性分析。结果 50例患者中8例获明确诊断,通过重复全脑血管造影检查发现1例右颈内动脉C_(1～2)段动脉;MRI检查发现3例隐匿性血管畸形,其中2例经手术证实;手术探查发现2例动脉瘤,1例动脉壶腹,1例中脑静脉畸形。结论 首次脑血管造影检查阴性的SAH患者应重复造影检查,并进一步行MRI检查,对于反复同一部位出血或头颅CT、MBI检查高度怀疑有病灶存在的患者应行手术探查。
Objectives In this article, the etiology of subarachnoid hemorrhage(SAH) of 50 patients with cerebral negative pan-angiography was evaluated and the therapeutic measures were discussed. Method Clinical data from 50 cases, who diagnosed as SAH but their pan-angiography was negative, were analyzed retrospectively. Results Exact causes of SAH were found in 8 cases of these 50 patients. Aneurysm of the right internal carotid artery (C1-2) was discovered in one case after repeated the pan-angiography. Cryptic AVMs were detected by MRI in 3 cases, of whom, 2 were verified during surgery. Exploratory surgery fornd that two patients had intracranial ruptured aneurysms, one had arterial ampulae and one had venous malformation in the midbrain. Conclusions The authors suggested that, for patients of SAH with initial negative cerebral pan-angiography, re-examination might be necessary and MRI was indicated for most of these patients. In patients with signs of rebleeding at the same site or when abnormalities were found during CT or MRI examination, exploratory surgery should be considered.
