肾上腺转移瘤CT引导下乙醇消融治疗

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1.5～7.2 cm.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≤3 cm的病灶18个(90%)完全坏死; 11个＞3 cm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.

CT-guided percutaneous ethanol injection in treatment of metastatic adrenal tumors

Objective:To validate the therapeutic value of CT-guided percutaneous ethanol injection (PEI) in the treatment of metastatic adrenal tumors. Methods: Thirty-one foci (diameter ranging from 1.5 cm to 7.2 cm) in 25 patients with metastatic adrenal tumors were treated with CT-guided PEI for more than twice. Plain and enhanced CT scans were performed 1-2 months after PEI to observe the size and necrosis of the tumors. Results: Post-PEI enhanced CT scan showed that 18 of the 20 foci with diameters less than 3 cm completely necrotized; 11 foci with diameters between 3 cm and 7.2 cm necrotized partially, and 2 foci completely necrotized after another 2-3 courses of PEI treatment. Conclusion: CT-guided PEI is a simple and minimally invasive means for treatment of metastatic adrenal tumors, and the therapeutic effect is satisfactory.
