The surgical treatment of patent ductus arteriosus.1955.

Fourteen cases of patent ductus arteriosus operated upon without a fatality have been presented. All were treated by ligation and division of the ductus. The importance of the safety factor provided by the Potts-Smith-Gibson clamp has been discussed. A detailed case report of one patient whose operation was complicated by excessive hemorrhage is given in detail. No cerebral or renal damage followed a prolonged period of cardiac massage and only slight permanent cord damage resulted from complete occlusion of the aorta for over 1 hour.
