Abstract

The vascular systems of the kidneys and gonads are highly susceptible to variations because of the degeneration of the mesonephros and mesonephric artery and the progressive ascending development of the metanephros. In this report, we present a rare case of a common arterial trunk originating from the left renal artery and supplying the left diaphragm, adrenal gland, and testis. Anatomical dissection of a 95-year-old male was conducted during the 2023 academic year at Tokai University Medical School. The left renal artery had a common trunk that bifurcated to superior and inferior branches, forming a T-shape. The superior branch was distributed in the left adrenal gland and diaphragm, whereas the inferior branch was distributed in the left testis. This anatomical variation likely results from the remnant of the mesonephric artery network structure, particularly the rete arteriosum urogenitale. Understanding such variations is crucial for radiologists and surgeons to avoid potential complications during diagnostic procedures and surgical interventions.

从肾动脉到横膈膜、肾上腺和睾丸的主干分支:一例胚胎学假说的观察报告。
由于中肾和中肾动脉的退化以及后肾的逐渐上升发育,肾脏和性腺的血管系统极易发生变异。在这个报告中,我们提出一个罕见的病例,一个共同的动脉干起源于左肾动脉,供应左膈,肾上腺和睾丸。东海大学医学院于2023学年对一名95岁男性进行了解剖解剖。左肾动脉有共同干,分为上、下两支,呈t形。上支分布于左肾上腺和横膈膜,下支分布于左睾丸。这种解剖变异可能是由于肾中动脉网络结构的残余,特别是泌尿生殖动脉网。了解这些变化对于放射科医生和外科医生在诊断过程和手术干预中避免潜在的并发症至关重要。
