Case Report: A right-sided testicular artery of renal origin, in coexistence with a renal artery duplication: Dissection findings with clinical significance

Purpose The current cadaveric report describes the abnormal origin and course of testicular arteries (TAs) in two donated cadavers, along with a renal artery (RA) duplication. Methods Dissection of the inferior vena cava (IVC) and the abdominal aorta (AA) branching patterns were performed in 90-year-old- and 76-year-old formalin-embalmed donated male cadavers. Results Variants of the TA origin and course were identified, as coexisting with RA variants. Case 1: A right-sided RA (RRA) duplication (recorded as superior and inferior renal artery-SRA and IRA) with origin from the AA, coexisted with a right TA (RTA) that originated from the IRA and descended anteriorly to the ureter. The left TA (LTA) originated from the AA proximal to the origin of the left RA (LRA). The LTA coursed in front of the common drainage of the left testicular and renal vein into the IVC. Case 2: A bilateral RA duplication was identified and recorded as SRA and IRA. The right-sided SRA originated from the AA upper level and played the role of the accessory RA (ARA). The main perfusion of the right kidney was performed by the IRA which was further trifurcated into a superior polar, an inferior polar (IPA), and a TA. The RTA had a high origin from the IPA. Conclusion The current study reported two cases of TAs with abnormal origin and course accompanied by an RA duplication. A thorough knowledge of the origin and course of the TAs has clinical implications for the kidneys and testicle’ surgery.
