High field MR-guided precise puncture aspiration for treatment of multilocular brain abscess / 中国介入影像与治疗学

ABSTRACT

Objective: To evaluate the efficacy and safety of high field MR-guided percutaneous precise puncture aspiration in treatment of multilocular brain abscess. Methods: Clinical data of 9 patients with multilocular brain abscess treated with high field 1.0T MR-guided percutaneous precise puncture aspiration were retrospectively analyzed. The operation time, complication and follow-up results were recorded. Results: Nine patients with multilocular brain abscess underwent 25 times of high field MR-guided puncture and aspiration therapy, among them 2 patients underwent 2 times and 7 cases underwent 3 times aspiration, and the technique success rate 100% (25/25). The operation time was 40-100 min, with an average of 75 min. All sucked pus was cultured with bacteria, and positive results were obtained in 8 patients. A small amount of subdural hemorrhage occurred in 1 patient, but no serious complication occurred. The symptoms were significantly improved in 9 patients during 6 months' postoperative follow-up, while imaging follow-up results showed subsided or granuloma formed in abscess cavities of all 9 cases, with an effective rate of 100% (25/25). Conclusion: High field open MR-guided percutaneous precise puncture aspiration is safe and effective for treatment of multilocular brain abscess.
