摘要
目的比较特发性醛固酮增多症(特醛症)几种术前诊断方法的价值。方法对特醛症患者行影像学检查、体位激发试验、肾上腺静脉插管取血检查。结果81例患者中,高血压者占100%,低血钾者占41.98%,血醛固酮升高者占80.25%,尿醛固酮升高者占32.91%。76例患者肾上腺B超检查的符合率为84.21%;75例患者CT检查的符合率为84.00%。26例患者行体位激发试验,激发后血醛固酮较基础值均升高。19例患者行肾上腺静脉插管取血检查,分泌较高侧与对侧血醛固酮之比均小于2.0,符合率为100%。结论影像学检查对特醛症的诊断有一定局限性;体位激发试验在原发性醛固酮增多症的分型诊断中有参考价值;肾上腺静脉插管取血检查的准确率高,对于影像学检查未能发现明显占位性病变者须行该项检查,以明确诊断。
Objective To evaluate preoperative diagnosis of idiopathic hyperaldosteronism （IHA）. Methods Image examination, postural stimulation test （PST） and adrenal vein sampling （AVS） were performed in patients with IHA. Results The patients with hypertension, low plasma potassium, high plasma aldosterone and high urinary aldosterone accounted for 100% , 41.98%, 80.25% , 32.91%, respectively. The accordance of ultrasonography and CT was 84.21% and 84.00%. Twenty-six patients had PST, and all had increase of plasma aldosterone. Plasma aldosterone after PST increased in all patients. The accordance of 19 patients had AVS was 100%. Conclusion PST has reference value in differential diagnosis. AVS has high accordance, and it should be clone in patients with negative image examination.
