Peripheral venous catheter fracture with cardiovascular embolization is a rare but potentially serious complication. Herein, we report a case of peripheral venous catheter fracture with embolization in the right ventricle in a preterm infant.The catheter fragment was successfully removed by surgical procedure via median sternotomy under cardiopulmonary bypass(CPB).We hope this case will increase awareness of this rare complication and improve the safety of catheterization.

Outcomes of operations for total anomalous pulmonary venous connection (TAPVC) have improved.However, postoperative pulmonary venous obstruction (PVO) remains the most significant complication, with high morbidity and mortality. We introduce a window anastomosis technique for repair of supracardiac TAPVC in infants. The mainstay of the surgical technique is to resect the anterior wall of the pulmonary vein confluence(PVC) and part of the posterior wall of the left atrium to form a large and undistorted “window to window” anastomosis.
