Patent Ductus Arteriosus Device Closure in Interrupted Inferior Vena Cava: Challenges Overcome and Lessons Learnt: A Case Series

Abstract

Interrupted inferior vena cava (IVC) with azygous continuation provides technical challenge in many percutaneous cardiac interventions. They are performed via the femoral venous access route. We describe four such cases in whom, patent ductus arteriosus (PDA) device closure was done in interrupted IVC. All the four cases were done using the femoral route. Two cases were done via retrograde approach through femoral artery access, in which one was closed with a muscular VSD device and the other with a Gianturco coil.

The introduction of newer closure devices helps in the retrograde approach. Two cases were done via anterograde approach through the femoral venous route, with a loop through the azygous vein. One child had transient bradycardia due to cardiac stretch which normalized after the device deployment and introducer system removal.

Thus, we describe different femoral approaches in interrupted IVC patients for PDA closure, with the difficulties faced and the complications managed.
