Seven renal arteries: a case report using MDCT angiography

Area of Science:

• Anatomical Variations
• Vascular Imaging
• Urology

Background:

• Anatomical variations of renal arteries can impact surgical procedures.
• Multi-detector computed tomography (MDCT) angiography is a key imaging modality for vascular assessment.

Observation:

• An incidental finding of seven renal arteries (three right, four left) in a 63-year-old male.
• Detailed analysis of origin, diameter, length, and trajectory of each renal artery and accessory renal arteries (AdRAs).

Findings:

• Main renal arteries had larger diameters at origin compared to AdRAs.
• Accessory renal arteries were significantly longer than the main renal arteries.
• Four accessory renal arteries were hilar, and two were superior polar.

Implications:

• Knowledge of complex renal artery anatomy is vital for urological and vascular interventions.
• This case highlights the importance of detailed pre-operative imaging to identify rare vascular anomalies.
• Understanding variations in renal artery branching patterns aids in preventing intraoperative complications.
