作者对1622例蛛网膜下腔出血(SAH)后脑血管造影证实的脑动脉瘤进行了研究。1287例(79％)接受了手术治疗。SAH 3天内进行手术的有4例(早期手术组),4～15天或超过15天手术者823例(后期手术组)。早期手术率36％占全部病人的29％,95％的病人行动脉瘤颈夹闭术。采用Hunt和Hess分级方法、SAH严重性根据基底池内血凝块厚度分为:未见、薄层和厚层。根据格拉斯哥预后计分(GOS)判断结果。早期手术组倾向于厚层SAH的Ⅳ、Ⅴ级病人,晚期手术组多为未见SAH的Ⅰ级病人。脑血管痉挛率为25％～46％。早期和晚期手病人各级恢复良好无差异,早期手术组死亡率高,在Ⅴ级明显。335例未手术病人中105例发生致命性
The authors studied cerebral aneurysms confirmed by cerebral angiography after 1622 patients with subarachnoid hemorrhage (SAH). 1287 patients (79%) underwent surgery. There were 4 cases (early surgery group) undergoing SAH within 3 days, and 823 cases (late surgery group) undergoing 4 to 15 days or over 15 days. Early surgery rate of 36% of all patients accounted for 29%, 95% of patients with aneurysm neck clipping. Using the Hunt and Hess grading methods, the severity of SAH was classified according to the thickness of the clot within the basilar pool: no, thin and thick layers. According to Glasgow prognostic score (GOS) to determine the results. The early operation group tend to thick SAH Ⅳ, Ⅴ level patients, late surgery group mostly without grade SAH patients. Cerebral vasospasm rate of 25% to 46%. Patients with early and late recovery at all levels with no difference in good, early surgical mortality was high, in grade Ⅴ significantly. In 335 cases of non-surgical patients 105 cases of fatal
