侧脑室肿瘤手术治疗策略

目的切除侧脑室肿瘤最佳手术入路目前仍存在争议,本文主要讨论影响手术切除侧脑室肿瘤的各种因素。方法本组共47例侧脑室肿瘤患者,平均年龄42岁,根据术前MRI检查确定肿瘤部位、侵犯的范围及肿瘤大小。其中经胼胝体入路23例,经皮层造瘘入路24例。通过MRI检查明确残余肿瘤大小及复发情况。结果肿瘤全切除31例,近全切除10例,大部切除6例。无手术死亡。所有肿瘤均经病理证实。结论侧脑室肿瘤术前应当根据肿瘤所在位置、生长范围及大小,供瘤血管的起源及静脉回流情况,及与周围结构的关系进行仔细分析,选择合适的手术入路。

Surgical management strategy of lateral ventricul tumors

Objective Optimal surgical pathway for lateral ventricle tumors is still controversial.The purpose of this study is to discuss the factors that affected the preference of the surgical techniques for removing lateral ventricle tumors.Methods A total of 47 patients underwent surgery for lateral ventricle tumors.The mean patient age was 42 years old.Preoperative magnetic resonance imaging （ MRI） images were examined to determine the location, expansion and size of each tumor.The transcallosal approach was used in 23 patients, and the transcortical approach was used in 24 patients.We performed MRI to determine the tumor size and recurrence or increased size of the residual tumor.Results Of all 47 cases,31 underwent total removal,10 subtotal removal and 6 large partial removal, with zero mortality. diagnosis were made pathologically. Conclusions Lateral ventricle tumors can be treated best by careful selection of the surgical approach according to localization of the tumor within the ventricle, the expansion side of the tumor, the size of the tumor, the origin of the vascular feeding branches, the venous drainage and the relationship of the structures.
