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.
