Late in-stent restenosis of the abdominal aorta in a patient with Takayasu's arteritis and related pathology

This report describes an in-stent restenosis of the infrarenal aorta in a patient with Takayasu's arteritis in a nonactive state. A 10-mm-diameter Wallstent had been deployed 42 months previously. The stented restenosed segment was replaced by a surgical graft. His-topathological examination of the excised aortic segment showed a thin layer of fibrocellular neointima and massive organized and calcified thrombus. To our knowledge, this is the first histopatho-logical report of a late in-stent restenosis of the abdominal aorta in Takayasu's arteritis.
