肾上腺静脉插管取血在原发性醛固酮增多症分型诊断中的意义

目的　探讨肾上腺静脉插管检查在原发性醛固酮增多症 (原醛 )分型诊断中的应用价值。方法　临床 14例明确为原醛患者 ( 11例腺瘤及 3例增生 )经肾上腺静脉插管检查 ,取双侧肾上腺静脉以及肾静脉水平下的下腔静脉采血 ,测各点醛固酮和皮质醇水平 ,并将结果与影像学检查及术后病理结果进行比较。结果　腺瘤患者插管结果与影像学检查及术后病理结果无统计学差异 ,符合率为 81 82 % ( 9/ 11) ,3例增生患者插管结果与影像学检查结果均相符。结论　肾上腺静脉插管检查在原醛的分型诊断中有较好的准确性 ,是影像学检查有疑问时可选择的良好方法。

Adrenal venous sampling in the differential diagnosis of primary aldosteronism

Objective To study the value of adrenal venous sampling (AVS) in the differential diagnosis of primary aldosteronism (PA).Methods Fourteen patients (11 adenoma and 3 adrenal hyperplasia) clinically diagnosed as PA were examined with AVS for measurement of plasma aldosterone and cortisol levels.Selectivity of AVS was assessed by the aldosterone level in each adrenal vein and in the infrarenal inferior vena cava plasma.The data were compared with CT and postoperative pathologic result.Results The diagnosis of adenoma by AVS in 9 (9/11) cases was in accordance with the postoperative pathologic findings.The diagnosis of hyperplasia by AVS in all 3 cases was in accordance with CT scanning result.Conclusion AVS should be selected to distinguish the PA without overt occupational lesion in CT scanning.
