Multi-detector CT Imaging of Double Left Renal Veins

Area of Science:

• Anatomy
• Embryology
• Vascular Surgery

Background:

• Renal vascular anatomy, particularly left renal vein variations, is vital for surgical planning.
• Embryological development of the inferior vena cava and renal veins can result in complex anatomical configurations.
• Awareness of these variations is essential to prevent surgical complications.

Observation:

• The study details two uncommon cases of dual left renal veins.
• These cases involved an orthotopic left common iliac vein and ectopic caval drainage.
• Multi-detector computed tomography (CT) imaging was utilized for detailed visualization.

Findings:

• The presented cases demonstrate rare anatomical variations of the left renal vein.
• These variations underscore the complexity arising from renal embryological development.
• Multi-detector CT imaging effectively identified these uncommon vascular anomalies.

Implications:

• Enhanced understanding of left renal vein anomalies improves surgical safety in abdominal and renal procedures.
• Detailed imaging of renal vascular anatomy is critical for surgeons.
• Knowledge of these variants aids in preventing intraoperative injuries and improving patient outcomes.
