[Localizations of Takayasu's disease (author's transl)]

Localizations of Takayasu's disease are described and discussed in relation to 10 cases. The affection causes panaortitis which produces stenosis, or less often dilatation, of the thoracic and/or abdominal aorta, and stenosis of occlusion of the arteries arising from the aorta. Lesions of the aortic arch and superior aortic branches, mainly subclavian and carotid, are the most frequently observed form of the disease, but coronary stenosis and aortic incompetence are sometimes noted. Lesions in the descending thoraco-abdominal aorta are frequently present, and stenosis and occlusion of the renal arteries are usually associated with the abdominal aortitis. Stenosis of the terminal aorta and iliofemoral axes is a more rare occurrence. The association of lesions in the aortic arch and its branches, and the descending aorta and its branches, was found in about 2/3rds of cases. Pulmonary arteries are affected in about half the cases according to recent reports.
