ABSTRACT

The results of analysis were summarized as follows; 1) Mean age of patients was 51 years. ICA aneurysms occurred more frequently in female(47) than male(13). 2) Distribution of ICA aneurysms were ophthalmic aneurysm 8 cases(13.3%), posterior communicating aneurysm 40 cases(66.6%), anterior choroidal aneurysm 7 cases(11.6%), bifurcation aneurysm 5 cases(8.3%). 3) Most common direction of aneurysmal dome in ophthalmic, anterior choroidal and posterior communicating aneurysm was posterior-inferior-lateral and in bifurcation aneurysm was posterior-superior. 4) Multiple aneurysm was 23 cases(38%). 5) Incidence of clinical vasospasm was 48.3% and that of rebleeding was 20%. 6) Clipping was done in all cases, 2 cases combined with wrapping and 2 cases with trapping. 7) Mortality rate was 21.6%.
