目的 :探讨超声引导下瘤内注射核素治疗肝脏血管瘤的方法与疗效。材料和方法 :3 0例肝脏血管瘤 (其中 7例多病灶 ) ,超声引导下经皮肝穿 ,瘤内注射3 2 P 胶体 ,2 9.6～ 3 88MBq (0 .8～ 10 .5mCi) ,单点或多点分次治疗。结果 :共穿刺5 3次 ,病灶累积辐射吸收剂量 3 0 2～ 183 4Gy ;8～ 2 0个月后 ,临床及超声证实痊愈 9例 ,显效 16例 ,有效 5例 ,无无效病例 ;无严重并发症。结论 :超声引导下瘤内3 2 P 胶体注射是治疗肝脏血管瘤的有效方法。 Objective: To investigate the method and effect of ultrasound-guided intratumoral injection of radionuclide on hepatic hemangiomas. MATERIALS AND METHODS: Thirty (30) patients with hepatic hemangiomas (7 of them were multifocal) underwent ultrasound guided percutaneous transhepatic intratumoral injection of 3 2 P colloids, 2 9.6-3 88 MBq (0.8-8.5 mCi) Point or multi-point treatment. Results: A total of 53 punctures were performed, and the cumulative dose of radiation absorbed by the lesions ranged from 302 to 4Gy 4Gy. After 8 to 20 months, 9 cases were cured clinically and ultrasonographically, 16 were markedly effective, 5 were effective, and none were ineffective complication. Conclusion: Ultrasound-guided intratumoral 3 2 P colloid injection is an effective method for the treatment of hepatic hemangiomas.
