目的探讨CT引导下经皮穿刺化学消融治疗肾上腺醛固酮瘤的价值。方法利用国产21G三孔针在CT引导下经皮穿刺化学消融治疗肾上腺醛固酮瘤6例,术后复查CT,观察治疗前后血压、血钾和血醛固酮的变化。结果6例肾上腺瘤患者的瘤径均<2cm,术后分次复查瘤体缩小,仅残留少许瘢痕组织。5例患者血压于术后5~7d降至正常;1例患者逐渐减少降压药物用量,术后第28天降至正常。所有病人血钾术后5~10d升至正常,血醛固酮于术后5~7d降至正常。结论CT引导下经皮穿刺化学消融治疗肾上腺醛固酮瘤是一种弥散程度高、创伤小、操作简便及费用少的介入方法。
Objective To investigate the value of CT-guided percutaneous radiofrequency ablation of adrenal aldosterone tumors. Methods Six cases of adrenal aldosteronoma were treated with CT-guided percutaneous chemical ablation of 21G three-hole needle. CT was observed after operation. Changes of blood pressure, serum potassium and serum aldosterone were observed before and after treatment. Results The diameter of 6 patients with adrenal adenoma was less than 2 cm. After the operation, the tumors were reduced in size and only a little scar tissue remained. The blood pressure of 5 patients dropped to normal 5 ~ 7 days after operation; one patient gradually reduced the dosage of antihypertensive drugs, and then dropped to normal on the 28th day after operation. All patients with potassium potassium rose to normal after 5 ~ 10d, serum aldosterone dropped to normal after 5 ~ 7d. Conclusion CT-guided percutaneous chemical ablation of adrenal aldosteronoma is a high degree of diffusion, trauma, simple and inexpensive intervention methods.
