增强磁共振引导下脑脓肿的立体定向穿刺手术治疗

Enhanced MR-guided stereotactic aspiration of brain abscess

目的探讨增强磁共振引导下立体定向穿刺手术治疗脑脓肿的临床疗效。方法回顾性分析18例增强磁共振引导下立体定向穿刺手术治疗的脑脓肿临床资料,包括年龄、性别、临床表现、病程、脓肿数量及部位、感染诱因及预后。结果 18例脑脓肿均穿刺成功,其中单发15例,多发3例。血源性4例,医源性5例,隐源性7例,耳源性及鼻源性各1例。治愈16例,死亡2例。结论在现代神经影像学的辅助下,立体定向穿刺抽吸治疗脑脓肿是一种安全、微创、可靠的治疗方法。

Objective To investigate outcome of enhanced MR--guided stereotactic aspiration of brain abscesses. Methods A retrospective analysis of the clinical data of 18 cases with brain abscesses treated with stereotactic aspiration was performed, including age, sex, clinical manifestation, course of disease, the number and location of brain abscesses, infection causes, and outcome. Results 18 cases of brain abscesses were aspirated successfully. There were 15 cases with solitary abscess and 3 cases with multiple abscesses. The predisposing factors were hematogenous （n=4）, iatrogenic （n = 5）, cryptogenic （n = 7）, otogenic （n = 1 ）, and rhinogenic （n = 1 ）. As a result,16 cases were cured and 2 died. Conclusion With the help of modern neuroimaging,enhanced MR--guided stereotactic aspiration for brain abscesses is a safe, minimally invasive and effective treatment.
