Subarachnoid hemorrhage of unknown origin. A 44 cases study.
44 cases (20 men and 24 women) of subarachnoid hemorrhage (SAH) of unknown origin were studied: the mean age was 54.1 yrs. Highest frequency of the disease was observed in 51-70 years old patients. There was only a slight involvement of consciousness (I-II grade of HESS and HUNT). Vascular hypertension was noticed in 45.5% of patients, but outcome did not differ in hypertensive and normotensive subjects. The CT findings showed a typical picture of SAH. 4 cases of perimesencephalic and peripontine hemorrhage were noticed. 24 patients underwent lumbar puncture. The angiographic study was normal in all patients. 14 subjects repeated four-vessel angiography. Transient hydrocephalus was found in 22.7% of patients. Approximately 70% of patients received antifibrinolytic therapy, either with or without calcium entry-blockers (nimodipine). Neither ischemic complications nor rebleeding were observed. Follow-up showed that all patients had survived 7-88 months after SAH. All subjects made a complete recovery and have since been able to resume work.
