Abstract

OBJECTIVE: We compare the frameless stereotactic hematoma aspiration (FSA) with frame-based stereotactic hematoma aspiration (FBSA) in intracerebral hemorrhage (ICH) about operative advantage and result. MATERIAL AND METHODS: Between January 2002 and December 2002, we surgically treated 30 patients presenting with spontaneous ICH at our hospital. 15 patients underwent FBSA via Codman-Roberts-Wells system and catheter placement with urokinase infusion and drainage, and 15 patients underwent FSA and catheter placement via neuronavigator with urokinase infusion and drainage.
RESULTS
The amount of remaining hematoma and removal rate were from 1 to 26 and 76% in FSA and from 2 to 55 and 60.4% in FBSA. The entry point was selected within 2.03+/-0.85 cm in a frontal direction from Kocher's point and 2.86+/-0.57 cm in lateral direction from Kocher's point and the trajectory was selected toward the distal margin of hematoma along the long axis of hematoma in FSA but the entry point was restricted within Kocher's point and the trajectory was selected toward the center of the maximum axial section of hematoma in FBSA. The mean time of operative preparation was mean 61 minutes in FSA and 78 minutes in FBSA. The number of patients not required with infusion of urokinase was 10 in FSA and 7 in FBSA. The mean duration of urokinase infusion was 3.6 day in FSA and 4.1 day in FBSA.
CONCLUSION
FSA is fast, simple and effective procedure. In comparison with FBSA, FSA has advantage in selecting the entry point and the trajectory for hematoma aspiration and catheter placement, and in a less time-consuming procedure.
