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.

Objective: The aim of the study is to assess the therapeutic effect and applicability of pectoralis major muscle turnover flap reconstruction for treatment of deep sternal wound infection after cardiac surgery in infants and children. Methods: From march 2013 to october 2021, 23 patients with deep sternal wound infection after cardiac surgery underwent pectoralis major muscle turnover flap reconstruction.The data and outcomes of the patients were retrospectively analyzed. Results: 20 patients were treated with unilateral pectoralis major muscle turnover flap reconstruction,3 patients were treated by bilateral pectoralis major muscle turnover flap. All of the sternal wounds healed successfully. All patients survived and were discharged without evidence of infection. In a follow-up period, ranging from 15 to 83 months (mean 32.6 months), all patients demonstrated normal development with no limitations to limb movements. There were no signs of chronic sternal infection in all of them. Conclusion:Pectoralis major muscle turnover flap reconstruction is a simple,feasible and effective treatment of deep sternal wound infection after cardiac surgery in infants and children,with minimal developmental problems.

Intramyocardial dissection following cardiac tumor excision is uncommon. The evidence available is limited to few case reports. 1 Herein,we report an infant with large cardiac fibrosarcoma arising from the interventricular septum and underwent surgical excision. Postoperative echocardiography revealed a cystic dissection located in the interventricular septum with residual shunts within the ventricular chambers. we performed conservative strategy due to the high surgical risk, difficulty of interventional therapy and hemodynamic stability.
