BACKGROUND: We present a rare case of an anomalous origin of the right subclavian artery (SA) from the pulmonary artery (PA) associated with ventricular septal defect (VSD) and aortic coarctation.
CASE REPORT: Critical aortic coarctation and VSD were diagnosed in a neonate, and coarctation angioplasty was successfully performed. Severe cardiac failure developed after this procedure, however, and closure of the VSD was planned.
RESULTS: The anomalous SA was diagnosed during the operation when the cardiopulmonary bypass was initiated. As the pulmonary blood flow decreased, a difference in pulse pressures between the right radial artery and the ascending aorta was noticed to be due to the subclavian steal phenomenon. The difference decreased from 60 mm Hg to 25 mm Hg following ligation of the SA at its origin from the PA. The patient was discharged on the eighth postoperative day without any problems.
CONCLUSION: An abnormal origin of the right SA from the main PA associated with VSD and aortic coarctation is a unique combination that, if unnoticed preoperatively, may create difficulties during the operation.
