Absent infrarenal inferior vena cava

An absent infrarenal inferior vena cava (IVC) can be congenital due to failure of development of the posterior cardinal and supracardinal veins, or acquired as result of intrauterine or perinatal inferior vena cava thrombosis.

It is an extremely rare anomaly.

The patient may present with  symptoms of lower-extremity venous insufficiency or idiopathic deep venous thrombosis, particularly in younger patients.

The non invasive modality of choice  are contrast enhanced  CT or MRI, which is preferred over ultrasound. The best invasive imaging modality is venography, particularly done if performed for surgical planning.

General features include:

  • infrarenal IVC with preservation of the suprarenal segment
  • common iliac veins may be absent
  • external and internal iliac veins drain into the ascending lumbar veins, which drain into the azygous-hemiazygous system
  • +/- collateral  paraspinal circulation
