    Abstract:
    An 84-year-old male was scheduled for coronary artery bypass graft surgery under general anesthesia. During cardiopulmonary bypass, the leakage of blood into the syringe being used for balloon inflation and the thermistor connector of the pulmonary artery catheter (PAC) was detected. Resistance was encountered when trying to withdraw the PAC. A surgical suture of the right atrium cannulation was stitched to PAC and was immediately released. Early detection of surgical damage to PAC and recognition of the entrapped PAC by gently withdrawing it avoided possible life-threatening complications, including pulmonary air embolism, and the inevitable of resternotomy. Transesophageal echocardiography, chest radiography, and fluoroscopy can help confirm any postoperative surgical damage following closure of the sternum or while in the intensive care unit.
