We report the findings in 26 cases of occlusive aortopathy (Takayasu's disease) encountered during eight years. The mean age was 25.3 years and female to male ratio was 2.7:1. Chest and local pain, fever, hypertension (70%) and absent pulses were accompanied by high erythrocyte sedimentation rate (ESR) 38 to 126 mm, eosinophilia 4 to 26%. All immunological tests were negative except tuberculin-test (PPD) with 65% positive. EKG was normal in three cases, 23 showed left ventricular hypertrophy, ST-T changes in two and acute myocardial infarction in two cases. The classification: Type I cervico-brachial or arch type with five cases, type II thoraco-abdominal type with six cases, type III peripheral type with four cases and generalized types combination of two or more of three types and/or pulmonary artery involvement, showed good correlation with clinical findings and prognosis. The occlusive aortopathy is an inflammatory disease of unknown origin, an auto-immune or genetic etiology may be involved.
