| ABSTRACT |
|
Author reviewed the 31 cases of multiple intracranial aneurysms clinically from January 1981 to July 1987, at Inje College Busan Paik Hospital. The results obtained were as follows: 1) The incidence of multiple intracranial aneurysm was 7.8%. In most cases(94%), the number of aneurysm was two. 2) Approximately over 70% of patients were 6th and 7th decades, male to female ratio was 1:3.4. 3) The location of multiple intracranial aneurysms was in order, on the opposite side(39%), on the same side(26%), one in the midline and one on the side(29%). The location of indivisual aneurysms was in order, P-com. A(36%), MCA(25%), A-com.
A(17%), ICA(13%). 4) The site of the ruptured aneurysm was determined by CT finding(55%), focal mass effect and spasm in angiography(29%), and others. The accurary was 97%. The possibility of rupture at each location was A-com. A(73%), P-com. A(57%), ICA(38%), MCA(31%). 5) 12 cases among them were treated with one-stage operation and 9 cases with two-stage operation. The post-operative favorable outcome was estimated in 13 cases(54%), the surgical mortality was 13%. There was no statistical difference between two groups. |
