Comparison of endovascular and surgical treatment for ruptured cerebral aneurysms with respect to short and long-term outcome

We compared the treatment for ruptured aneurysms from the clinical and radiological follow-ups after endovascular (GDC) or surgical treatment. There were 142 surgically treated cases and 38 endovascular treated cases from. May 1997 to December 2001. In. endovascular cases there were four A-com,four MCA, 12 ICA and 18 posterior circulation aneurysms. In. surgical cases, there were 53 A-com ACA, 51 MCA, 36 ICA and two posterior circulation aneurysms. The clinical outcomes of endovascular and surgical treatments were correlated with the H & H grades before treatments. At short stage, 71% of endovascular and 78.2% of surgical cases showed a favorable outcome (GOS GR or MD) (p = 0.3). Long-term clinical follow lips (14.5 to 58 months) showed 77.7% of endovascular and 87.7% of surgical cases resulted in GR or MD (p = 0.17). In endovascular cases, 22.2% showed recurrence during the follow-up period and five of them needed re-treatment. We experienced failed endovascular approach at acute stage in seven cases which changed to surgery. In conclusion, the short and long term clinical results of endovascular treatment were acceptable comparing surgical clipping. High recurrence rate after GDC treatment did not permit future completeness of the treatment. Still the treatment alternative between endovascular or surgical treatment may change depending on the criteria of each institution, attention should be paid to the disadvantages of endovascular treatment as the first choice for ruptured aneurysms.
