HOW TO SUTURE AND CLOSE THE PDA WITH MINIMAL BLEEDING BY PLACING A BALLOON CATHETER INTO THE PDA WHILE USING A CARDIOPULMONARY BYPASS

In the case of cardiac surgery under cardiopulmonary bypass for patients with complication of PDA, after cardiopulmonary bypass begins, a longitudinal incision is made in the pulmonary artery close to the PDA. Then the cardiopulmonary bypass flow is decreased and a balloon cathether is inserted into the aorta through the PDA. The balloon is immediately inflated to stop fleeding. Then we increase the cardiopulmonary flow. A matress double armed suture with pledget is made from outside to inside the PDA on the anterior wall, and then inside to outside on the posterior wall. Three or four more matress sutures are then added in the same way. The cardiopulmonary bypass flow is decreased, the balloon is removed, and the sutures are tied. The PDA is shut in the condition of being pressed from outside by the sutures. Then, we increase the cardiopulmonary bypass flow again. If there is any leakage, we strengthen the closure by Z sutures. After it is confirmed that there is no leakage, the incision in the pulmonary artery is closed by sutures.
