CT Fluoroscopy-guided Aspiration of Intracerebral Hematomas: Technique and Outcomes

ABSTRACT

OBJECTIVE: The authors evaluated the feasibility and targeting accuracy of CT fluoroscopy (CTF)-guided catheter placement and aspiration of intracerebral hematoma (ICH)s. MATERIALS AND METHODS: Nine patients (mean age, 63.3 +/- 15.3 years) were treated by CTF-guided hematoma aspiration under local anesthesia. The targeting errors in the lesion center, volume of the aspirated hematoma, accuracy of the final catheter position, procedure time, and clinical outcomes were evaluated. RESULTS: All catheters were successfully placed in the center of the hematoma. The mean volume of the aspirated hematoma was 20.6 +/- 8.8 mL (pre-treatment, 44.7 +/- 20.1 mL; post-treatment, 24.1 +/- 13.8 mL). The average procedure time was 25.1 minutes (range, 18-32 minutes). In one case with a scanty residual hematoma, the catheter was removed at the end of the procedure. In the remaining eight cases, the catheter was left in the residual hematoma for drainage and all catheter tips were accurately located in the final position. There were no procedure-related complications, including rebleeding and infection. CONCLUSION: CTF-guided ICH aspiration is a feasible, quick, and accurate procedure which could substitute for stereotactic methods. The accurate catheter position provided by real-time observation enables an effective aspiration and drainage of hematomas.
