ABSTRACT

Objective To summarize the clinical and imaging features of subarachnoid hemorrhage(SAH) and its complications and prognosis. Methods The clinical data of 502 cases of SAH were retrospectively analyzed and summarized. Results There were 84.3 % (423/496) patients sufferring from intense headache, dizziness or vertigo (13. 1%, 66/496 ), disturbance of consciousness ( 27. 5%, 138/496 ), partial neurologic impairment (58.2% ,292/496) ,meningeal irritation sign(72.5% ,364/496). The positive rate of digital subtraction angiogra-phy was 54.1% (93/172). Aneurysm was the common reason of SAH (20. 1%, 101/496). Prognosis in most pa-tients was better,but the old patients suffered from high mortality. Conclusions The cause and clinical manifesta-tion of SAH varies,cerebral angiography often could help find the cause of SAH. Most SAH patients recover well.
