Apical entry of single main renal artery

Area of Science:

• Urology
• Vascular Anatomy
• Embryology

Background:

• Renal artery variations can impact surgical planning and outcomes.
• Understanding congenital anomalies of the renal vasculature is crucial for interventional procedures.

Observation:

• Two cases of extrahilar entry of a single main renal artery were identified.
• Selective renal angiography revealed arterial entry via the upper pole and venous exit near the entry site.

Findings:

• This anatomical variation involves an atypical pathway for the main renal artery.
• The reported cases represent a rare deviation from standard renal vascular anatomy.

Implications:

• Accurate pre-operative imaging is essential to identify such renal artery variations.
• Knowledge of these anomalies aids in preventing surgical complications during renal procedures.
