Evaluation of a new method of pericardial drainage after cardiac surgery

: Recently pericardial drainage after cardiac surgery has been done using silicon tubes of small diameter. For more effective drainage, we set one of the drainage tubes circularly, coursing behind the left ventricle, through the transverse sinus, and ending at the right side of the atrium (circular pericardial drainage). As compared to conventional drainage using 28 Fr chloroethilene tubes, drainage time was shorter and no late tamponade had occurred. Circular pericardial drainage may be useful.
