Transcatheter treatment for pulmonary artery occlusion secondary to pulmonary embolism in an infant.

We report a case of successful recanalisation of the left pulmonary artery after occlusion due to embolic thrombi in a 9-month-old infant after surgical repair of a common atrioventricular canal with tetralogy of Fallot. A transhepatic approach was used because of caval vein thrombosis. After the failure of high-pressure balloon angioplasty, the left pulmonary artery was successfully recanalised with cutting balloons, followed by stent implantation with an excellent result.
