CLOSURE OF A PATENT DUCT ARTERIOSUS (PDA) DURING CARDIOPULMONARY BYPASS-USE OF FOGARTY BALLOON CATHETER

Closure of a patent duct arteriosus (PDA) during cardiopulmonary bypass was performed successfully in five cases by using a balloon catheter. All five patients had pulmonary hypertension, case No. 3 hadmitral valve disese, and case No. 4 had a recanalized PDA. A Fogarty balloon catheter was used to control the return of blood from the aorta through the PDA before closure. The postoperative course was uneventful in every cased.
