Description
Introduction
Aberrant renal arteries can be due to abnormal ascension or rotation of the fetal kidney. Aberrant arteries from the inferior pole are only seen in 3% of dissected cadavers, providing an opportunity to understand the rare variation and its effects on physiological and histological findings1. These anomalies can be asymptomatic or lead to impaired urine flow through the ureter, leading to hydronephrosis.
Methods
A 76-year-old male donor cadaver was dissected in the PCOM South Georgia anatomy lab in accordance with the first year curriculum for abdominal and kidney dissection. Observations and measurements were noted.
Results
The left kidney presented with an aberrant artery at the inferior pole, which was approximately 9 cm in length and anastomosed with the abdominal aorta superior to the bifurcation. There was an associated aberrant renal vein that branches out into two smaller veins that drain directly into the IVC. Upon comparison of the kidneys, the left kidney was larger and weighed more. The left kidney also has an altered structure exhibiting the presence of additional renal papilla, minor calyx, and major calyx sites leading to the renal pelvis to account for the additional site of blood flow to the kidney.
Discussion
Due to the cadaver’s cause of death being cardiogenic shock, there is no way to determine that the aberrant renal artery was detrimental to their health during life. This variation does present considerations that should be made anatomically with any procedures involving the kidneys and their vasculature. Without medical records, we can only appreciate the developmental anomaly.
