Transposition of inferior vena cava
Citation, DOI & article data
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 inferior vena cava 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
A left-sided inferior vena cava (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.
- color Doppler ultrasound may play a role as screening
- contrast-enhanced CT confirms the diagnosis and also the course of the inferior vena cava
