Abstract
Recently, nonanastomotic rupture of vascular grafts is hardly reported. We experienced a very rare case of giant nonanastomotic aortic pseudoaneurysm of Hemasield woven double velour graft, 1 year and 4 months after Bentall’s procedure and hemi-arch replacement. The patient was a 27-year-old male with Marfan’s syndrome who had funnel chest. The rupture site was found on the intact surface of Hemasield graft. Constant friction between a sternal wire and the graft was highly suspected as the cause of rupture. In such cases, to avoid a friction between the sternum and the graft, using a thick artificial pericardium covering the anterior mediastinum, or closing the sternum without metal wires should be considered, and periodical follow-up computed tomography is necessary for long-term.
