Transfemoral plug closure of patent ductus arteriosus: experiences at Osaka Prefectural Hospital.

Transfemoral plug closure of PDA (patent ductus arteriosus), which was originally introduced by Porstmann in 1968, was successful in 73 of 74 consecutive patients at Osaka Prefectural Hospital. Some instrumental and technical modifications were made. There has been no mortality, and no dislodgment of the plug occurred after the modified plug with a barbed head was used although a major complication during the procedure was the dislodgment of the plug into the aorta, which occurred early in three cases. There was no recurrence of shunting or any other complications in the long-term follow-up studies. For the patient with a simple isolated PDA over 3 years of age, the catheter technique is considered to be the method of choice to close the ductus.
