| ABSTRACT |
|
Much controversies still exist with respect to the risk factors influencing symptomatic cerebral vasospasm. In our study, the patient group had some unique characteristics, ie.:42.5%(65) of the 153 patients were aged 60 years or older(mean;55.6 years) and consequently the proportion of Hunt-Hess grade 3-5 was higher than grade 1-2(57.5% vs 42.5%). The authors analyzed the relationship between vasospasm and Hunt & Hess grade, Fisher grade, hydrocehalus, age & hypertension among these 153 early operative cases after a 3 year follow up study. The incidence of vasospasm was significantly higher in the Hunt-Hess grade III, IV, V and the Fisher grade III, IV, compared to grade I & II, and also in preoperative hydrocehalus but it was insignificant in old and hypertensive patients. These results suggest initial severe direct insults and complicating preoperative hydrocephalus increase the chance of postoperative symptomatic vasospasm in this older aged, poorer grade study group. |
