Background and purpose: The purpose of this study was to compare clinical outcomes and treatment-related complications between coiling and clipping for ruptured distal anterior cerebral artery (DACA) aneurysms.
Methods: Eighty-four consecutive patients (M:F = 36:48; mean 53.8 years) with ruptured DACA aneurysms were treated by either clipping (n = 46, 54.8%) or coiling (n = 38, 45.2%). The clinical outcomes and procedure-related complications were evaluated and compared between the two groups.
Results: Procedure-related complications tend to occur more frequently in the clipping (n = 6, 13.0%) than coiling group (n = 1, 2.6%) (P = .121). At discharge, 51 patients (60.7%) had favorable outcomes (Glasgow outcome scale [GOS], 4 or 5). There was no significant difference between the two groups in favorable outcome (63.2% vs. 58.7%; P = .677). Hunt and Hess (HH) grade (P < .001; 95% CI, 3.354-29.609) and treatment modality (P = .044; 95% CI, 1.039-16.325) were independent risk factors for poor outcome (GOS, 1-3).
Conclusions: Coiling was more favorable to clipping in clinical outcomes and incidence of treatment-related complications for ruptured DACA aneurysms.
