ABSTRACT

We present a term infant with an isolated haemodynamically insignificant interrupted IVC with a structurally normal heart which was diagnosed antenatally and confirmed postnatally. Antenatal scan showed evidence of an interrupted IVC with venous return via an Azygos vein draining into the Superior Vena cava (SVC) with a structurally normal heart with no evidence of left atrial isomerism. Interrupted IVC with azygos continuation typically has a benign prognosis due to compensatory venous flow. It is important to be aware of this condition if there is a need for central venous catheter placements for any other reason. The infant was discharged and reassured the family about a benign prognosis and no restrictions from a cardiology perspective.
