作者报告用钌~(106)/铑~(106敷贴器治疗3例脉络膜黑色素瘤。肿瘤周围作氩或氪激光。用荧光眼底血管造影定期观察,追踪34～36个月。结果治疗后3～6个月内的放射效果理想;肿瘤处脉络膜和视网膜的血管几乎消失,治疗后12个月肿瘤周围血管闭锁,肿瘤及其表面的视网膜血管继续萎缩。治疗前的血管荧光造影显示:动脉早期相可见肿瘤内的大血管。晚期相瘤组织着染而显示强荧光。肿瘤周围有多数高荧光的小点,相当于色素沉着处显低荧光。肿瘤表面的视网膜血管变细,
The authors reported 3 cases of choroidal melanoma treated with 钌~(106)/铑~(106) applicator. Argon or helium laser was used around the tumor. Regular observation with fluorescent fundus angiography followed 34 to 36 months. Results After treatment 3 The radiation effect was satisfactory within 6 months, the blood vessels of the choroid and retina at the tumor almost disappeared, the blood vessels around the tumor were blocked at 12 months after treatment, and the retinal vessels on the tumor and its surface continued to shrink.The fluorescein angiography before treatment showed that: The large blood vessels in the tumor can be seen, and the advanced phase tumors are stained with strong fluorescence, with a large number of highly fluorescent dots around the tumor, which corresponds to hypofluorescence at the site of pigmentation, and thinning of the retinal blood vessels on the tumor surface.
