Rezumat:

During educational dissections at a human adult specimen, male, a complex
picture of anatomical variants was encountered. Bilateral doubled renal arteries
were found: on the right side superior hilar and inferior hilar renal arteries
and on the left side superior hilar and inferior polar renal arteries. All these
renal arteries emerged from the abdominal aorta. Also bilateral doubled
testicular arteries were found. On the right side the medial testicular artery
emerged from the abdominal aorta while the lateral testicular artery left the
superior renal artery. On the left side the lateral and medial testicular
arteries emerged as a common trunk from the abdominal aorta. This trunk
originated from aorta behind the left renal vein and arched over that vein to
descend and to divide in front of it. The two kidneys were keeping a fetal
aspect, lobulated, more obvious on the left side. The right hepatic artery was
found originating from the superior mesenteric artery; it coursed posterior to
the portal vein and was sending the cystic artery. The right gastric artery
emerged from the initial segment of the gastro-duodenal artery. Even though some
morphological and topographical aspects regarding this complex anatomical
variation have been described, it seems that the bilateral presence of doubled
renal and testicular arteries has not been reported. The left testicular trunk
arching over the left renal vein must be considered when discussing the
nutcracker syndrome. During diagnostic and surgical approaches at the levels of
the renal, gonadal and hepatic vessels, associations of anatomical variants and
the bilateral presence of these must be suspected.
