Group 1 (52 patients) underwent angiogram followed by emergency surgery. If the patient was admitted during routine working hours, angiogram was performed the same day followed by immediate surgery. Patients who were admitted after working hours, underwent angiography the next morning followed by immediate surgery. The only factor that decided how soon the patient was operated after admission was the availability of cerebral angiogram laboratory. Only in patients admitted in grade IV, the anglogram was deferred till their clinical grade improved. But they were immediately taken up for surgery, once the angiogram was performed. Group 2 (57 patients) patients underwent angiography on the next working day after admission and surgical clipping in next available routine operation theatre time. The preoperative management , anaesthesia and post operative management protocols were the same for the two groups. Briefly each patient, after admission was clinically categorized according to Hunt and Hess grading.[11] Before surgery, all patients were started on steroids, anti convulsants, a benzodiazepine tranquilizer, opiold analgesics, a laxative, and nimodipine. Post operatively steroids, anticonvulsants and nimodipine were continued. Patients in grade II, III and IV were also vigorously treated with triple - H (hypertension, hypervolemia and haemodilution) therapy.[12],[13]
