Unusual Presentations of Takayasu's Arteritis: Report of two cases

Takayasu's arteritis is occlusive disease of aorta, its main branches, and pulmonary artery. Its clinical manifestations are quite variable, but comes from mainly stenotic or aneurysmal change of the vascular wall. We experienced two cases of unusual presentations of Takayasu's arteritis, one with thorcoabdominal aortic aneurysm (Crawford type III) and the other with atypical coarctation of descending aorta. Surgical procedures were graft replacement of thoracoabdominal aortic aneurysm with implantation of inferior mesenteric artery supplying almost all abdominal vicera to the graft, and graft bypass of the coarctation. They survived postoperatively with improved clinical symptoms.
