Truncus Arteriosus -Report of a Case-

동맥간(動脈幹) 1례(例) 보고(報告)

Truncus arteriosus is a rare and highly lethal cardiac anomaly characterized by a single arterial trunk emerging from the heart and supplying the coronary, systemic, and pulmonary circulations, The first successful correction of truncus arteriosus was reported by McGoon et al. in 1968 and was based on experimental work reported by Rastelli et al. in 1967 in which a conduit consisting of a homograft of the ascending aorta and aortic valve was used to establish continuity between the right ventricle and the pulmonary arteries, Modification of this procedure using a Dacron tube valved with porcine xenograft instead of a homograft have resulted in the current definite treatment for truncus arteriosus. This report describes an 3 years and 4 months old boy with heart failure from type I truncus arteriosus who was diagnosed as the V. S. D. with pulmonary hypertension preoperatively and underwent corrective surgery employing the Rastelli procedure using a Dacron conduit valved with canine xenograft, but died due to massive bleeding from the anastomosis sites in operating room.
