Suture Line Dehiscence after Endovascular Aneurysm Repair in a Patient with Marfan Syndrome

抄録

A 68-year-old man with Marfan syndrome developed de-novo leakage after endovascular aneurysm repair of a Dacron graft. Findings at subsequent reoperation suggested that the rebound force on the endograft generated by marked longitudinal deformation in the Dacron graft may have placed stress on the suture line, leading to partial dehiscence. The Dacron graft seemed to provide a stable proximal landing zone. However, the strong tendency of some endograft devices to return to their original shape may apply stress that affected weakened regions of the native aorta.
