Data from 1986 through 2008 were extensively reviewed on a consecutive series of 3,770 patientswho referred for ruptured/unruptured cerebral aneurysms. Forty-seven patients in the S group and 48 in the T group who met inclusion criteria, were selected for this study.
RESULTS:
The incidence of regrowth were noted that two out of total 47 patients (4.3%) in the S group, and none in the T group. The clip slippage was not observed in both groups. And there was no statistical difference (p = 0.242) in terms of regrowth between two groups. Seven out of 47 cases (14.9%) developed post-clipping seizure in the S group. On the other hand, two (4.2%) of 48 patients presented the symptom in the T group. Also, there was no significant difference (p = 0.091) between two groups.
CONCLUSIONS:
The metallic types of clip employed for the microsurgical cerebral aneurysm clipping does not have any significant clinical outcome differences in this study.
