title: A Rare Case of Dacron Graft Rupture due to Friction against a Rib.
abstract: A 54-year-old man underwent aortic repair for the infected thoracoabdominal aneurysm with a woven Dacron graft (Vascutek, Renfrewshire, Scotland) treated with gentian violet. Four months later, he complained of sudden back pain, resulting in preshock status. Computed tomographic scans showed massive hematoma around the Dacron graft, suggesting graft rupture. Initially, emergency thoracic endovascular aortic repair was performed, which was subsequently followed by open repair. The Dacron graft had a small hole, which was completely compatible with the site contacting with the rib. The graft rupture was considered due to its friction against the rib. We report on a rare event of mechanical Dacron graft rupture after the thoracoabdominal aortic replacement.
