经额中回皮质入路显微手术切除侧脑室前部肿瘤

Microsurgical resection of the tumors located in the anterior portion of the lateral ventricle via transcortical middle frontal gyrus approach

目的总结并分析经额中回皮质入路切除侧脑室前部肿瘤的显微外科手术技巧及临床疗效。方法回顾性分析20例经额中回皮质入路手术切除侧脑室前部肿瘤病人的临床资料。结果肿瘤全切除l5例,次全切除3例,部分切除2例。无手术死亡病例。术后随访6个月～3年,平均1年;术后6个月GOS评分:5分14例,4分2例,3分1例(术后2年死于其他疾病),失访3例。结论额中回皮质入路具有手术损伤小、术野暴露清楚等优点,是切除侧脑室前部肿瘤的首选入路之一。

Objective To review the surgical skills and evaluate the clinical effects in resection of the tumors located in the anterior portion of the lateral ventricle via transcortical middle frontal gyrus approach. Methods Clinical data of 20 patients with tumors located in the anterior portion of the lateral ventricle undergoing microsurgical resection via transcortical middle frontal gyrus approach were analyzed respectively. Results Total tumor resection was achieved in 15 patients, subtotal resection in 3 and partial resection in 2. No patient died. Seventeen patients were followed up for average of 1 year, ranged from 6 months to 3 years. The GOS scores at 6 months after operation were as follows： 5 in 14 cases, 4 in 2 and 3 in 1. The patient who got GOS score of 3 was died of other diseases at 2 years after operation. Conclusions The transcortical middle frontal gyrus approach has such advantages as slight injury and better surgical field exposure, and can be used as one of the first choices for the tumors located in the anterior portion of the lateral ventricle.
