原发性醛固酮增多症患者选择性肾上腺动脉造影的影像学特征

Imaging Features of Selective Adrenal Arteriography in Patients With Primary Aldosteronism

目的:明确原发性醛固酮增多症(PA)患者数字减影血管造影(DSA)下肾上腺动脉的影像学特征。方法:回顾性分析2018年1月至2019年12月在南昌大学第二附属医院确诊PA并行经皮超选择性肾上腺动脉栓塞的119例患者的DSA图像,描述肾上腺动脉的数量、起源、分布、角度和直径。结果:119例PA患者的平均年龄为(49±11)岁,其中男性71例(59.7%)。所有患者均成功找到至少1条肾上腺动脉,共获得192条肾上腺动脉,其中肾上腺上、中、下动脉分别有20条(10.4%)、40条(20.8%)、132条(68.8%),起源于肾动脉、腹主动脉、膈下动脉的肾上腺动脉分别有82条(42.7%)、72条(37.5%)、38条(19.8%)。72.8%(83/114)的左肾上腺动脉和60.3%(47/78)的右肾上腺动脉分布在第1腰椎水平。28.1%(54/192)的肾上腺动脉分布在第2腰椎水平,4.2%(8/192)的肾上腺动脉分布在第12胸椎水平。左肾上腺动脉与起源动脉肾动脉、副肾动脉、腹主动脉的夹角范围分别为35.90°~160.07°、27.08°~171.99°、0°~158.70°,右肾上腺动脉与上述起源动脉的夹角范围分别为18.43°~172.53°、69.26°~114.62°、12.32°~232.85°。左、右肾上腺动脉的平均直径分别为(0.98±0.45)mm和(1.27±0.42)mm。结论:本研究提供了PA患者较为详细的肾上腺动脉放射学解剖特征,作为人体解剖学特征的补充,可为肾上腺动脉介入治疗提供实用的指导。

Objectives:To clarify the radiological anatomy features of adrenal arteries derived from digital subtraction angiography(DSA)in patients with primary aldosteronism(PA).Methods:The DSA images of 119 patients diagnosed with PA and underwent percutaneous selective adrenal artery embolization from January 2018 to December 2019 at the 2nd Affiliated Hospital of Nanchang University were retrospectively analyzed,and the number,origin,distribution,angle and diameter of adrenal arteries were analyzed.Results:The mean age of 119 PA patients was(49±11)years,with 71(59.7%)males,and at least one adrenal artery was successfully identified in all patients,a total of 192 adrenal arteries were analyzed.There were 20(10.4%)upper,40(20.8%)middle and 132(68.8%)lower adrenal arteries.Adrenal arteries originating from renal arteries accounted for 42.7%(82/192),adrenal arteries originating from the abdominal aorta accounted for 37.5%(72/192),and those from the inferior diaphragmatic arteries accounted for 19.8%(38/192).72.8%(83/114)of left adrenal arteries and 60.3%(47/78)of right adrenal arteries distributed at the level of the first lumbar vertebrae.28.1%(54/192)adrenal arteries distributed at the level of the second lumbar vertebrae,and 4.2%(8/192)adrenal arteries at the level of the 12th thoracic vertebrae.The angle range of left adrenal arteries intersecting with the origin arteries was 35.90°to 160.07°(renal artery),27.08°to 171.99°(accessory renal artery),0°to 158.70°(abdominal aorta);for right adrenal arteries,it was 18.43°to 172.53°(renal artery),69.26°to 114.62°(accessory renal artery),12.32°to 232.85°(abdominal aorta),respectively.The average diameters of left and right adrenal arteries were(0.98±0.45)mm and(1.27±0.42)mm,respectively.
