Abstract

CT has become the most useful, non-invasive diagnostic method as the initial exmination in the diagnosis ofruptured intracranial aneurysm with intracranial hemorrhage(subarachnoid, intracerebral and intraventricularhemorrhage), hydrocephalus and infarction. Furthermore, high resolution CT can demonstrate aneurysm itself. Butangiography is the last and conclusive method as yet, for better evaluation of vascular anatomic structure ofaneurysm for surgery. Authors analyzed 40 cases of ruptured intracranial aneurysm confirmed by CT, angiographyand/or surgery at Chonnam National University Hospital from July, 83' to July, 85'. The results were as follows:1. The most prevalent age group was the 5th decade(35%), and female patient(57.5%) was more comon than male. 2.Angiographic findings were as follows: 1) Multiple aneurysm was found in 8 patients (20%): the one of thesepatients is tripple, the others are double. 2) The location of aneurysm, in order ot frequency, were : ACA andA-com aneurysm in 23 cases(47%). ICA and P-com aneurysm in 17 cases(35%), basilar tip aneurysm in 4 cases(8%), MCAaneurysm in 3 cases(6%) and PCA aneurysm in 1 case(2%). 3) Hydrocephalus was detected in 22 cases (55%): 21 cases(95%) of these cases were demonstarated within the first 3 weeks after attack. 4) Detection of aneurysm itseslfwas 20 cases(50%). 5) Cerebral infarction was 5 cases(12.5%). 6) Subarachnoid enhancement on post-contrast scanwas 8 cases(20%).
