目的分析总结自发性蛛网膜下腔出血致脑积水的诊治经验。方法对急性脑积水行侧脑室额角穿刺外引流术,术后复查头颅CT,5～7d后闭关观察1～3d;对术后慢性脑积水,临床症状和头颅CT无改善表现,3周至半年行脑室-腹腔分流术治疗。结果 2周时复查头颅CT,脑室双侧额角最大宽度与该层面颅内最大横径之比均<0.3。随访6个月～5年,均恢复良好。结论自发性蛛网膜下腔出血致脑积水是临床上预后不佳的危险因素,如能积极治疗预后佳。 Objective To summarize the diagnosis and treatment of hydrocephalus caused by spontaneous subarachnoid hemorrhage. Methods Acute hydrocephalus was performed lateral ventricle forehead puncture. The head CT was performed after the operation. After 1 to 3 days after 5 to 7 days, there was no improvement on postoperative chronic hydrocephalus, clinical symptoms and head CT. Six months line of ventricle - peritoneal shunt treatment. Results At 2 weeks, the head CT scan showed that the ratio of the maximal width of bilateral forehead to the maximal transverse diameter of the cranial plane was <0.3. All cases were followed up for 6 months to 5 years and recovered well. Conclusions Hydrocephalus caused by spontaneous subarachnoid hemorrhage is a risk factor for poor prognosis in clinical practice, such as positive treatment of prognosis.
