Subarachnoid hemorrhage constitutes approximately 10% of cases of cerebrovascular disease and its incidence ranges between 11 and 28 cases/100,000/year. More than 80% of cases are secondary to rupture of cerebral aneurysm; however, in 5 to 16% of patients with subarachnoid hemorrhage it is not possible to find a cause (subarachnoid hemorrhage with negative angiography). This group of patients represents a dilemma for the correct diagnosis, treatment and prognosis; there is no consensus on the criteria to repeat the angiography after the first negative study. The results of our study includes 14 patients with subarachnoid hemorrhage and negative angiography. The angiographic study was repeated two or more times. Our observations suggest that the overall prognosis for these patients is very good (86%). The risk of another hemorrhage after discharge from the hospital is small. Our results are compared with those in other published series.
蛛网膜下腔出血约占脑血管疾病病例的10%，其发病率为每年11至28例/10万。超过80%的病例继发于脑动脉瘤破裂；然而，在5%至16%的蛛网膜下腔出血患者中，无法找到病因（血管造影阴性的蛛网膜下腔出血）。这群患者在正确诊断、治疗和预后方面存在两难境地；对于首次血管造影阴性后重复血管造影的标准尚无共识。我们的研究结果包括14例血管造影阴性的蛛网膜下腔出血患者。血管造影检查重复了两次或更多次。我们的观察结果表明，这些患者的总体预后非常好（86%）。出院后再次出血的风险很小。我们的结果与其他已发表系列的结果进行了比较。
