title: Causes of morbidity and mortality, with special reference to surgical complications, after early aneurysm operation: a prospective, one-year study from neurosurgical units in Sweden.
abstract: In the present prospective study, 6.93 of Sweden's 8.59 million inhabitants (81%) were covered by the five participating centres. All patients with verified aneurysmal SAH admitted between June 1, 1989 and May 31, 1990, were enrolled. Basically, all participating centres have the same management protocol for SAH victims, including ultra-early referral to a neurosurgical unit, followed by pan-angiography and surgery as early as logistically possible. In this presentation, 145 patients who preoperatively were in Hunt & Hess Grades I-III and who underwent surgery for a supratentorial aneurysm within 72 h after the bleed, are evaluated. Eighty-one % (117 patients) made a good recovery. The morbidity was 12% (17 patients) and the mortality 7% (11 patients). The most common cause of unfavorable outcome was surgical complications, which accounted for 8% of the total series (12 patients). A subanalysis of these cases did reveal a positive correlation to higher age and more severe SAH on CAT scan.
