Open stent-grafting for adult patent ductus arteriosus with a distal aortic arch aneurysm.

Abstract

Closure of adult patent ductus arteriosus (PDA) is difficult for its variation. We report a case of open stent-grafting for a 67-year-old woman who had PDA and a concomitant distal aortic arch aneurysm. The pulmonary/systemic flow ratio was 1.88, and the pulmonary arterial pressure was 34/21(25). The operation was done through a median sternotomy under hypothermic cardioplegic arrest. We opened the anterior wall of the arch just distal to the left subclavian artery and placed a stent-graft into the descending aorta. At 5 months after discharge, three-dimensional computed tomography showed disappearance of PDA and no endoleak of the stent-graft.
