Comparison of clinical results between GDC treatment and direct surgery for ruptured cerebral aneurysms

We present a comparison of clinical results between GDC treatment and direct surgery for ruptured cerebral aneurysms. From May 97 to April 98, 32 aneurysms were treated by direct surgery (DS) or GDC treatment. Treatments were selected depending on the clinical grade, degree of hematoma and anatomical aspect of the aneurysms. There were 13 GDC treated cases and 19 direct surgery cases. In GDC cases, there were acute stage embolization for ruptured basilar aneurysm, recurrence of case after clipping for BA-SCA aneurysm, advanced age cases, and systemic complication cases. Glasgow outcome scale (GOS) in GDC cases were 8 GR, 2 MD and 3 SD. GOS in direct surgery cases were 7 GR, 4 MD, 4 SD and 4 deaths. Cases of severe subarachnoid hemorrhage with hematoma influenced the high death rate in direct surgery group. There were three complications associated with the procedure in the GDC group, however, the rate improved after advancement of the procedure. In conclusion, GDC treatment for ruptured cerebral aneurysm was satisfactorily acceptable compared to the results of direct surgery, however, more cases will be needed for precise comparison.
