摘要
目的 探讨立体定向脑活检方法的可靠性和安全性,研究手术方法及技术要点。方法 回顾性分析我院1999年6月至2005年11月,CT或MRI引导下立体定向活检47例。其中男32例,女15例。年龄18-83岁,平均年龄36.4±14.8岁。病灶位于:大脑半球25例,基底节及丘脑13例,鞍区6例,多发病变3例。结果 活检病理诊断:星形细胞瘤Ⅰ级22(46.8%),星形细胞瘤Ⅱ级5例(10.6%),星形细胞瘤Ⅲ级1例(2.1%),胶质母细胞瘤(Ⅳ级)3例(6.4%),炎性病变、转移瘤各3例(6.4%),颅咽管瘤、脑囊虫病各2例(4.3%),脑胶质瘤病、假瘤型炎性脱髓鞘病、结核瘤各1例(2.1%),胶质增生或未明确诊断3例(6.4%)。活检确诊率94.6%,无并发症发生。结论 立体定向脑深部病灶活检技术安全、可靠,对临床诊断、鉴别诊断、治疗的选择及手术有重要的意义。
Objective To explore the operation technical note and accuracy of CT. MRI- guide stereotactic biopsy in brain lesion. Methods Retrospectively reviewed a consecutive series of 47 cases with brain lesion, underwent stereotactic biopsy with ASA-602S stereotactic frame. All cases presented with supratentoreal lesions. Results Conclusive histopathologic diagnosis was achieved in 44 patients(94. 6M), there was no mortality and hemorrhage-related morbidity followed by biopsy in all patients. Conclusion Stereotactic biopsy is accurate for pathological diagnosis and sufficiently to guide subsequent therapy for the questionable lesions in brain.
