Successful stenting of an obstructed Glenn anastomosis in a 20-month-old child

Children with univentricular heart disease may benefit from the Glenn operation (superior vena cava to right pulmonary artery anastomosis), one of the palliative treatment stages. Preoperative and postoperative variables like thrombosis, arrhythmias, and superior vena cava syndrome af-fect postoperative mortality. A 20-month-old child, known to have complex congenital heart dis-ease with single ventricle physiology. She had Blalock-Taussig shunt in early infancy and then left Glenn anastomosis while she was recovering. Twenty-five days later, she developed acute thrombosis of her Glenn anastomosis. She was hemodynamically unstable with severe desatura-tion, and the decision was made for catheter-based intervention. Balloon dilatation of the throm-bosis initially failed. However, relief of the blockade using 2 overlapping stents was successful and improved her pulmonary blood flow, avoiding urgent surgery for her.
