Supracardinal veins (develop a little latter). Inferior vena cavography showed a complete obstruction of the upper end of the inferior vena cava immediately below the diaphragm, reflux of contrast medium into thin and tortuous hepatic veins, and numerous intrahepatic and cavocaval collaterals (Figure 1). Later on the inferior part of posterior cardinal vein on the left side starts degenerating, however, it’s still connected to the subcardinal vein via the mesonephric shunt. Various adjunctive techniques have been reported for challenging inferior vena cava (IVC) filter retrievals (14). Anomalies of the inferior vena cava (IVC) and its variations were first described by Abernethy in 1793 in a 10-month-old child with polysplenia and dextrocardia who presented with a congenital mesocaval shunt and continuation of IVC with the azygos vein (CCA) [1-3].The IVC develops sequentially, primarily between the sixth and eighth gestational weeks, with the formation of anastomoses and .

The normal inferior vena cava is composed of four main segments in a caudal direction: hepatic, suprarenal, re-nal, and infrarenal segments. The IVC begins in the abdomen at L5 and ends in the thorax at T8, where it enters the . On the left side the mesonephric shunt becomes incorporated into the IVC and gives rise to the left renal vein. Stretching across 8 vertebrae (L4 to T8), it is about twice the length of the abdominal aorta.
The inferior vena cava (IVC) is a large retroperitoneal vessel formed by the confluence of the right and left common iliac veins. The mesonephric shunt itself forms as a result of the anastamosis between the subcardinal and the posterior cardinal veins. MRI confirmed a 20 cm hepatic cyst in the right lobe compressing the inferior vena cava (IVC; figure 2).
3 Lateral visceral tributaries: right suprarenal vein, renal veins, and right testicular/ovarian vein.
