目的探讨CT引导下经皮穿刺无水乙醇消融术(PEI)对肾上腺转移瘤的治疗价值。方法25例肾上腺转移性肿瘤,共计31个病灶。病灶直径1.5~7.2cm。采用CT引导下无水乙醇瘤内注射进行治疗,治疗次数≥2次,治疗后1~2个月,行CT增强扫描,观察肿瘤大小、坏死情况。结果PEI治疗后CT增强扫描复查,20个病灶直径≤3cm的病灶18个(90%)完全坏死;11个>3cm的病灶绝大部分坏死,经过再次重复治疗,2个病灶彻底坏死。结论CT引导下经皮穿刺乙醇消融疗法治疗肾上腺转移瘤,疗效确切,且简便、创伤小。
Objective To investigate the value of CT guided percutaneous ethanol ablation (PEI) in the treatment of adrenal metastases. Methods 25 cases of adrenal metastatic tumors, a total of 31 lesions. Lesion diameter 1.5 ~ 7.2cm. CT-guided intravenous injection of ethanol into the treatment, the number of treatment ≥ 2 times, 1 to 2 months after treatment, CT enhanced scan to observe the size of the tumor and necrosis. Results After PEI, all the lesions were completely necrotic in 18 lesions (90%) with diameter ≤3cm. Most lesions were necrotic in 11 lesions> 3cm. After repeated treatment, the two lesions were completely necrotic. Conclusion CT-guided percutaneous ethanol ablation therapy for adrenal metastases, the exact effect, and simple and less trauma.
