经胼胝体-穹隆间入路显微手术切除第三脑室肿瘤

Microsurgical removal of the third ventricle tumors via transcallosal-interforniceal approach

目的探讨经胼胝体-穹隆间入路显微手术切除第三脑室肿瘤的外科技术，提高第三脑室肿瘤的手术治疗术后病理效果。方法回顾性总结采用经胼胝体-穹隆间入路显微手术切除的12例第三脑室肿瘤病例。结果肿瘤全切除4例，次全切除6例，大部切除2例。颅咽管瘤5例，畸胎瘤2例，星形细胞瘤2例，生殖细胞瘤2例，胶样囊肿1例。术后发生近期记忆障碍1例，尿崩症1例，硬膜下积液1例，经治疗后痊愈。结论经胼胝体-穹隆间入路适合用于切除第三脑室肿瘤，损伤小，并发症少。

Objective The purpose of this study is to improve the therapeutic effect of the third ventricle tumors removed via transcallosal-intelforniceal approach by exploring the surgical techniques. Method 12 cases with the third ventricle tumors which were removed by microsurgical techniques via transcallosal-interforniceal approach were retrospectively analyzed. Results Total removal, subtotal removal and partial removal of the tumors were achieved in 4 cases, 6 cases and 2 cases respectively. The cases included 5 eraniopharyngiomas, 2 teratomas, 2 astrocytomas, 2 germinomas and 1 colloid cyst. Postoperative complications included short term memory disorder, diabetes insipidus and subdural hydroma, each of them occurring in 1 case and being cured. Conclusions The transeallosal-interfornieeal approach is one of the optimal approaches to remove the third ventricle tumors because of its mini-invasion and less complications.
