小肾患者的血管造影诊断价值

目的 探讨血管造影在小肾患者的诊断价值。方法 对32例临床疑诊为肾动脉狭窄或原因不明的小肾患者进行血管造影。结果 血管造影诊断为肾动脉狭窄性肾萎缩12例,表现为肾动脉主干及其分支狭窄或闭塞;肾性肾萎缩17例,表现为肾动脉开口部与主干起始部间突然变细,呈“喇叭状”,主干及其分支均匀性变细;肾发育不全3例,表现为肾动脉主干、分支均匀变细,肾内动脉分支密集。结论 肾动脉造影在肾动脉狭窄性肾萎缩、肾性肾萎缩和肾发育不全的鉴别诊断中具有较大价值。

Value of angiography in the diagnosis of patients with small kidney

Objective To explore the diagnostic value of angiography in small kidney patients. Methods Angiographies were performed in 32 patients with small kidney of unknown etiology or with suspected renal arterial stenosis (RAS). Results Twelve cases of renal atrophy due to RAS were diagnosed by angiography, which demonstrated renal artery stenoses or occlusions. Angiography of 17 patients with nephrogenic renal atrophy displayed homogeneous shrinkage of the renal arteries except in the ostium. In 3 patients with renal hypoplasia, angiography showed narrowed renal arteries and tiny renal arterial branches. Conclusion Renal artery angiography is of important values in the differential diagnosis between renal atrophy due to RAS, nephrogenic renal atrophy and non-renovascular renal atrophy, and renal hypoplasia.
