Mortality and Morbidity of Surgery for Unruptured Inracranial Aneurysms Stroke 29:1531-1538, Raaymakers,T.W.M.,et al, 1998 See this aricle in Pubmed Article Abstract We included 61 studies that involved 2460 patients(57%female;mean age 50 years)and at least 2568 unruptured aneurysms(27%>25 mm,30%located in the posterior circulation).Mortality was 2.6%(95%confidence interval[CI],2.0% to 3.3%).Permanent morbidity occurred in 10.9%(95%,CI,9.6%to 12.2%)of patients.Postoperative mortality was significantly lower in more recent years for nongiant aneurysms and aneurysms with an anterior location;the last 2 characteristics were also associated with a significantly lower morbidity.In studies published between 1966 and 1996 on clipping of unruptured aneurysms,mortality was 2.6%and morbidity was 10.9%.In calculating the pros and cons of preventive surgery,these proportions should be taken into account.
