Risk of Subarachnoid Hemorrhage After Surgical Treatment of Unruptured Cerebral Aneurysms Stroke 30:1181-1184, Tsutsumi,K.,et al, 1999 See this aricle in Pubmed Article Abstract Four of the 115 patients suffered SAH either from a de novo aneurysm (2) or from regrowth of clipped aneurysm (1), or from regrowth after wrapping (1). Additionally, 1 patient also suffered SAH from an unstudied basilar aneurysm. One pati ent was incidentally found to have de novo aneurysm and underwent reoperation 14 years after the first operation. The cumulative risk for SAH for the 114 cases excluding the basilar aneurysm case was 1.4% in 10 years and 12.4% in 20 years. Although this study confirmed the long-term efficacy of clipping unruptured aneurysms, the risk of SAH was high compared with that in the general population, even after treatment. Considering the high mortality rate of SAH, long-term follow-up by angiography may be w arranted for patients with surgically treated unruptured aneurysms.
