In Takayasu's disease full radiological exploration of the arteries requires multiple injections of a contrast medium, and this would be difficult to achieve in the course of one single examination. In the present study, two non-invasive methods--digital angiography and cross-sectional echography--were used comparatively to evaluate arterial lesions in 13 ambulatory patients presenting with this disease. Conventional arteriography had previously been performed in 11 of them. The results obtained with digital angiography were considered satisfactory in 12 patients. All underwent aortic and pulmonary echography. Digital angiography and cross-sectional echography provide full, reliable and non-invasive exploration of the aorta and pulmonary artery. Echography shows abnormal thickness of the vascular walls, but the arterial branches can be explored only by digital angiography. The value of these two non-invasive methods is discussed.
