The aim of the study is to evaluate the vascular variations and incidental pathologies in potential living renal donors using 160-slice multidetector computed tomography (MDCT) angiography.
This is an observational study conducted at the Department of Radiology from January 2017 to May 2022. In this study, we performed retrospective data analysis of 61 CT renal angiograms, totaling 122 kidneys of potential renal donors, using a Toshiba 160 slice MDCT scanner with a four-phase CT image acquisition protocol, performed for pre-transplant workup. All patients had normal renal functions.
Of our 61 patients, 34 (55.7%) were male and 27 (44.3%) were female, and their mean age was 31.2 ± 9.4 years. We have found 31 (50.8%) variations in the right renal arteries and 21 (34.4%) in the left renal arteries. Of these patients, 13 had bilateral renal arterial variations. The late confluence of the renal vein was found in 3.3% of males, multiple right renal veins in 7 (11.5%), and left renal veins in 2 (3.3%). By distributing the data according to gender, we noticed more diversity in the renal vessels of male patients. Left renal artery variations were more frequent in males (16, 76.2%) than in females (5, 23.8%), and they were statistically significant (p=0.02). Likewise, variations in the right renal arteries were also more frequently found in males (19, 61.3%) as compared to females (12, 38.7%). Right renal vein variations were more common in males (9, 81.8%) as compared to females (2, 18.2%) (p=0.05).
Frequent renal vascular variations and incidental pathologies in potential living donors were found by MDCT examination, and these vascular variations should be analyzed before renal transplant.
本研究旨在利用160层螺旋计算机断层扫描（MDCT）血管造影术评估潜在活体肾供体的血管变异及偶然发现的病变。
这是一项于2017年1月至2022年5月在放射科进行的观察性研究。在本研究中，我们使用东芝160层MDCT扫描仪及四期CT图像采集方案，对61例CT肾血管造影进行回顾性数据分析，共计122个潜在肾供体的肾脏，这些检查用于移植前评估。所有患者肾功能均正常。
在我们的61例患者中，男性34例（55.7%），女性27例（44.3%），平均年龄为31.2±9.4岁。我们发现右肾动脉变异31例（50.8%），左肾动脉变异21例（34.4%）。其中，13例患者双侧肾动脉均有变异。肾静脉晚期汇合在3.3%的男性中发现，多条右肾静脉7例（11.5%），左肾静脉2例（3.3%）。按性别分布数据时，我们注意到男性患者肾血管的多样性更多。左肾动脉变异在男性中（16例，76.2%）比女性（5例，23.8%）更常见，且具有统计学意义（p=0.02）。同样，右肾动脉变异在男性中（19例，61.3%）也比女性（12例，38.7%）更常见。右肾静脉变异在男性中（9例，81.8%）比女性（2例，18.2%）更常见（p=0.05）。
MDCT检查发现潜在活体供体中肾血管变异及偶然病变较为常见，在肾移植前应分析这些血管变异情况。
