Suzuki et al.119 reported on the post-surgical overall clinical outcome in 603 patients with an ACoA aneurysm. Of these patients, 367 (61%) had an excellent outcome, 107 (18%) had a good outcome, 99 (16%) had a fair/poor outcome, and 30 (5%) died. Of the 264 patients who presented in Hunt and Hess Grades 0–III, 86% had an excellent or good outcome.
Fukushima et al.37 reported on the overall clinical outcome post-surgery in 138 patients with an ACoA aneurysm. In 119 cases (86%) the outcome was excellent or good, and 8 (6%) died. Of the 83 patients presenting in Hunt and Hess Grades I–III, 92% had an excellent or good outcome.
In our study, 15 cases underwent microsurgical clipping with Hunt and Hess grade I- III , 40% grade III, 40% grade II …show more content…

In 7 of these cases (20%) the treatment failed. This high rate of failure can be explained because the technical armamentarium in the mid-1990s was not as advanced and sophisticated as it is today. Of the 29 treated aneurysms, it was possible to achieve a complete occlusion in 23 (79%), whereas the occlusion was only partial (neck remnant) in the remaining 6 cases (21%). These investigators observed a post- procedural temporary neurological deficit in 2 cases, and the procedure-related permanent morbidity was 3.5% (1 case). No procedure-related death was reported.
Tsutsumi et al.128 reported on the overall results in 19 ruptured tiny (diameter ≤ 3 mm) ACoA aneurysms. Six- teen patients presented in Grades I–III, and 3 cases were categorized in Grade IV. Complete aneurysm occlusion was obtained in 84% of cases, whereas near-complete occlusion was obtained in 16% of cases. In 15 patients (79%) the outcome was good, whereas in 3 cases (16%) the clinical follow-up showed severe disability, and 1 patient (5%) died of severe vasospasm. None of the 18 patients who were followed clinically for a median period of 39.5 months showed
