To evaluate the risk of definitive intracranial microsurgical aneurysm obliteration as a function of the timing of the operative intervention, we retrospectively reviewed 106 consecutive patients in good clinical condition who underwent such surgery. The patients who were operated upon within the first 8 days of their most recent subarachnoid hemorrhage formed the 'early' group; the patients operated upon between the 9th and 31st day were considered to have undergone 'late' surgery. On the basis of their clinical outcome the patients were allocated to one of four outcome categories ('good', 'fair', 'poor', 'death') both at the time of their hospital discharge and at their most recent clinical re-evalation, a minimum of 6 months after discharge from the hospital. There was no significant difference in the operative mortality in each group (early surgery, 5%; late surgery, 4%); additionally, no significant difference was noted in the incidence of either intraoperative complications or postoperative morbidity. A suggestive but statistically insignificant increase in the incidence of postoperative cerebral ischemic events was seen in the 'early' surgery group (8% vs. 4% for the 'late' surgery group). The potential significance of these findings for the timing of intracranial aneurysm surgery is discussed.
