The origin of the renal artery in mammals and its anomalies

Bilateral Aberrant Renal Arteries With Anomalous Right Testicular Artery Arising From Aberrant Right Renal Artery Associated With Bilateral Polycystic Kidneys: A Case Report

“…Thus the aberrant renal arteries in this case are as a result of bilaterally persisting mesonephric arteries of the middle group . Felix also stated that although any of these nine arteries may become the gonadal artery, it usually arises from the caudal group .In the present case the right testicular artery has originated from aberrant right renal artery so we believe that it has been derived from middle group as well Brenmer explained that spermatic branches of renal origin were due to an early connection of a mesonephric artery with kidney which is normally lost [18].…”

A Study of Segmental Branching Pattern of Double Renal Arteries

“…As the kidney ascends, the arterial degeneration begins at the cephalad end of the metanephros, the segmental branch to the lower pole is the one most likely to persist as an accessory vessel (Graves 1969). A persistent segmental artery to lower pole may provide the origin of the gonadal artery and the one to the upper pole may give an adrenal artery (Bremer, 1915). 13 Ravery 14 et al explained origin of testicular artery from accessory renal arteries, as both have a common source of origin and testis receives branches during anterior crossing of kidneys.…”

Prior knowledge helps the surgeons to prevent iatrogenic testicular atrophy.…”

An Autopsy Case of Double Inferior Vena Cava Accompanied by Atypical Lateral Branches of the Abdominal Aorta

“…The right accessory vessel may be derived from the nutritious artery, arising from the common iliac artery (Bremer 1915;Shore 1929), of the metanephros which ascends dorsolaterally to the mesonephros, and consequently is located anteriorly to the right inferior vena cava and behind both the ureter and the testicular vessels (Text- Fig. 3).…”

“…In general, the main renal artery originates in the most caudal suparenal artery which is one of the lateral splanchnic branches from the dorsal aorta, or in the testicular artery, to the mesoderm of the mesonephric ridge (Bremer 1915 ;Kumaki 1980). The right renal artery, however, in the present case seems to be the persistent common trunk supporting the mesonephric ridge where both the suprarenal gland and the testis develop, in whole or in part, from the mesoderm.…”
