title: Natural history of aortoarteritis: an angiographic study in 26 survivors.
abstract: The natural history of aortoarteritis was angiographically studied in 26 surviving patients (19 female; 7 male). The interval between the initial and current angiographic study was 38-228 months (mean -84.46 months). All patients underwent panaortography during both studies and one patient also underwent pulmonary angiography. The lesions were extensive involving the ascending, arch and the descending thoracic and/or the abdominal aorta (Type III) in 15 patients; localized to the arch alone (Type I) in five patients and to the descending thoracic and/or abdominal aorta in five patients (Type II). Pulmonary angiography in the solitary patient with clinical features of pulmonary hypertension showed occlusion of the lower lobe branch of the right pulmonary artery. The lesions were occlusive in 19 patients, aneurysmal in one patient and mixed in six patients. While four patients developed fresh lesions in the follow-up period, two showed progression of existing lesions and one revealed partial thrombosis of an aneurysm. Persistently elevated erythrocytic sedimentation rate (> 40 mm) was identified as a reliable indicator for activity of inflammatory process and disease progression. The stable nature of the lesions in 20 out of 26 patients in this study indicates a non-progressive course in the healed stage of aortoarteritis and suggests a conservative approach to the management of this disease in all patients except those with severe, life-threatening manifestations.
