Surgical Treatment of High Pressure Patent Ductus Arteriosus
Thirteen patients with high pressure patent ductus arteriosus were operated upon. There was no operative mortality in this group. Twelve patients have shown remarkable clinical improvement, and there was a decrease in the pulmonary arterial pressure at the time of recatheterization in 11 of these patients restudied. One patient developed severe pulmonary hypertension and died six and one-half years after operation.
The pulmonary arterial systolic pressure dropped minimally in two patients, despite marked clinical improvement. Both patients had associated lesions: a large ventricular septal defect in one and severe congenital aortic stenosis in the other. Both patients are to be operated upon.
All patients with a predominant left-to-right shunt and a patent ductus arteriosus should have division of the patent ductus arteriosus. If a concomitant lesion requiring open-heart operation, such as a ventricular septal defect or aortic stenosis, is present, it should be corrected at a later date.
