目的 ;立体定向同位素32P内放疗治疗颅咽管瘤。立体定向同位素32P内放疗治疗颅咽管瘤。方法对40例囊性颅咽管瘤行立体定向穿刺、囊性内放疗。结果 32例术后6~38个月随访,CT或MRI瘤腔消失率69%,显著缩小31%;30例视力、视野障碍改善。结论 CT导向立体定向技术为脑深部肿瘤的内放疗和化疗提供精确定位和简便安全给药有效途径,对周围组织结构的全身影响极为轻微。
Objective; Stereotactic isotope 32P radiotherapy for craniopharyngioma. Stereotactic isotope 32P radiotherapy for craniopharyngioma. Methods Forty cases of cystic craniopharyngiomas were treated with stereotactic puncture and cystic internal radiation. Results 32 cases were followed up from 6 to 38 months after operation. The rate of malignant cavity disappearance on CT or MRI was 69%, which was significantly reduced by 31%. The visual acuity and visual field were improved in 30 cases. Conclusion CT guided stereotactic technique provides an effective method for accurate positioning and safe administration of internal medicine and chemotherapy for deep brain tumors with minimal systemic effects on the surrounding tissue.
