Insights
A novel hybrid technique successfully treated acquired left pulmonary vein occlusion in a child with Fontan circulation. This minimally invasive approach avoids risky open-heart surgery for complex venous obstructions.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Fontan circulation presents unique challenges in managing acquired vascular complications.
- Acquired left pulmonary vein occlusion is a rare but serious complication following cardiac surgery.
- Previous surgical repair can lead to complex anatomical issues affecting venous return.
Abstract:
A 5-year-old child with a Fontan circulation presented with acquired left pulmonary vein occlusion related to a previous surgical repair. We managed this lesion using a hybrid technique to perforate, dilate and stent the obstructed vessel. This approach should be considered when percutaneous access to the pulmonary veins is challenging (such as in a Fontan circulation). It also avoids the need for a high-risk redo sternotomy and cardiopulmonary bypass procedure.
