Renal vein entrapment, especially concerning the right renal vein, represents a scarcely explored anatomical aberration. The right renal vein's pivotal role in renovascular renal hemodynamics underlines the clinical significance of its compression, which can precipitate an elevated renal venous pressure gradient in relation to the inferior vena cava. This report delineates a unique instance of right renal vein entrapment in a 92-year-old male cadaver, identified during routine dissection. This entrapment is due to an unusual course of the right middle suprarenal artery that originates from the abdominal aorta and traverses inferior and retrocaval, causing the middle suprarenal artery to course anteriorly and superiorly to the right renal vein. This case, not paralleled in the extant literature, bears resemblance to the left renal vein entrapment in nutcracker syndrome (NCS) and thereby raises conjectures about possible renal manifestations akin to NCS in similar anatomical anomalies. The primary objective of this report is to augment the understanding and clinical relevance of this rare anatomical deviation in renal health.
肾静脉受压，尤其是右侧肾静脉受压，是一种鲜少被研究的解剖变异。右肾静脉在肾血管肾血流动力学中起关键作用，这凸显了其受压的临床意义，因为它可导致相对于下腔静脉的肾静脉压力梯度升高。本报告描述了在一名92岁男性尸体常规解剖过程中发现的一例罕见的右侧肾静脉受压情况。这种受压是由于右中肾上腺动脉走行异常所致，该动脉起自腹主动脉，在肾静脉下方和后方穿过，致使中肾上腺动脉在右肾静脉前方和上方走行。此病例在现有文献中未见类似报道，与胡桃夹综合征（NCS）中的左肾静脉受压相似，因此引发了对于类似解剖异常中可能出现类似于NCS的肾脏表现的猜测。本报告的主要目的是增进对这种罕见的肾脏解剖变异的理解及其临床相关性。
