There is little information on outcomes of surgical clipping for elderly patients with unruptured intracranial aneurysm unfavorable for coil embolization. The purpose of this study was to evaluate the angiographic and clinical outcomes in elderly patients with unruptured intracranial aneurysms treated with surgical clipping in a single center.
Between October 2003 and October 2013, 37 patients older than 70 years (range, 70-79) with 48 saccular unruptured intracranial aneurysms which were treated with surgical clipping were enrolled. The angiographic follow-up, clinical outcomes, and complications were evaluated.
Complete obliteration was achieved by clipping in 46 (95.8%) aneurysms and residual neck was observed in 2 (4.2%) aneurysms. Angiograph outcomes were maintained on 6-month follow-up CT angiography. Six (13.5%) patients had neurological deficit immediately after surgery, but 4 patients recovered thereafter. At 6-month follow-up, 36 (97.3%) patients had no neurological deficit, but the neurological deficit still remained in 1 (2.7%) patients.
Surgical clipping provided stable occlusion for the unruptured intracranial aneurysms which had unfavorable configuration for coil embolization in patients older than 70 years and morbidity was not found to be frequent in these elderly patients.
