Transposition of inferior vena cava

Transposition of inferior vena-cava (also known as left sided IVC) refers to a variant course of the inferior vena cava. It is the most common anomaly of IVC and occurs due to persistence of left supracardinal vein.

Diagnosis of left sided IVC is important for

  • planning of vascular procedures like portosystemic shunts
  • abdominal aortic aneurysm repair
  • ligation of IVC in thromboembolic disease
  • placement of IVC filter
  • nephrectomy and renal transplantation

Gross anatomy

A left sided IVC usually ends at left renal vein and crosses anteriorly to join normal pre-hepatic segment of IVC. Sometimes it crosses more posterior to aorta. Distally the IVC is formed by the confluence of the common iliac veins.

Radiographic features

  • colour Doppler ultrasound may play a role as screening
  • contrast-enhanced CT confirms the diagnosis and also the course of the IVC
