title: Coarctation of the abdominal aorta--case report with autopsy.
abstract: An autopsy case of coarctation of the abdominal aorta incidentally found in an 80-year-old male was presented. The stenotic lesion extended below the level of renal artery to the bifurcation and showed elongated hypoplastic type. Histological examination revealed adventitial fibrosis, vasa vasorum with occlusive change, degeneration and disappearance of the medial elastic fibers, and initial fibrosis. These features of lesser degree could also be found in the rest portion of the aorta and its branching arteries. It seemed reasonable to speculate that the inflammatory process worked on as the etiologic factor in the present case. The microscopic features had some resemblance to Takayasu's disease, but the macroscopic figures were quite unusual for it. Etiological possibility of aortitis in the present case was discussed.
