摘要: ✓ Between 1980 and 1987, 1622 patients with angiographically verified ruptured cerebral aneurysms were admitted within 7 days after subarachnoid hemorrhage. A retrospective analysis evaluated both the timing of surgery in operative status nonsurgical patients. The patients' clinical grade according to Hunt Hess classification was assessed at admission, a comparative outcome carried out for each relation time surgery: those operated on from Day 0 3 undergoing 4 or later. Among cases, fatal rebleeding occurred 105 cases vasospasm 69 cases. These divided into one two groups, either an early- late-management group, group analyzed by grade. mortality rates early-surgery groups higher than late-surgery especially Grade V, which rate significantly different. However, 174 nons...
