显微手术治疗侧脑室三角区脑膜瘤

目的 探讨显微手术治疗侧脑室三区脑膜瘤的疗效。方法 总结8例经显微手术治疗侧脑室三角区脑膜瘤的临床资料。结果 全组7例获得全切，肿瘤全切除率为87．5％，术后并发同向偏盲4例，偏瘫1例，精神症状3例，经非手术治疗均恢复正常，无手术死亡。1例次全切除，术后3a复发，经再次手术而痊愈。结论 显微手术技术是治疗关键。侧脑室三角区脑膜瘤手术难度大，合理的手术入路、精细的手术操作与良好的术后引流是全切肿瘤、提高疗效的重要因素。

Microsurgical treatment for meningioma of trigone in lateral ventricles

[Objective] To explore the clinical outcome of microsurgery in the treatment of meningioma at the trigone of lateral ventricles. [Methods] The clinical data of 8 cases with meningioma at the tfigone of lateral ventricles, who underwent microsurgery, were summarized. [Results] Total resection was performed in 7 of 8 cases and the total resection rate was 87.5%.Postoperative complications, which included co-direction hemianopia in 4 cases, hemiplegia in 1 and psychic symptom in 3,were all cured by nonsurgical therapy. There was no surgical mortality. Part resection was performed in 1 case with recurrence in postoperative 3 years and reoperation was performed with recovery. [Conclusions] Microsurgical technique is the key to treatment of meningioma. Microsurgery of mengingioma is performed at the trigone of lateral ventricles with high difficulty. Appropriate surgical approach and exposure, elaborate operation and adequate postoperative drainage are very important for total resection of the tumor and improvement of clinical outcomes.
