[Takayasu's disease. Value of digital intravenous angiography. 44 cases]

Forty-four patients with Takayasu's arteritis were explored by digital intravenous angiography either for diagnostic purposes and pre-therapeutic assessment (n = 29) or immediately after surgery (n = 15). There were 36 women, 6 men and 2 children; mean age was 31 years. The contrast medium (mean volume 140 ml) was injected into central (74%) or peripheral (26%) veins. No other angiographic exploration was contemplated in 24 patients selected for medical treatment. Among 15 patients destined to surgery or percutaneous angioplasty, 13 were operated upon without further angiography and 2 underwent arteriography since the distal vascular bed beyond the major lesions could not be evaluated adequately. Data obtained from post-operative evaluation (n = 15) were satisfactory, with 1 failure in this group. Digital intravenous angiography seems to be reliable enough to be used as first examination in patients with suspected Takayasu's arteritis. The procedure is well tolerated and can be repeated for optimum determination of the operation date. Arteriography can now be reserved to those rare cases where digital angiography has failed; it can then be limited to the study of a specific territory, the site of puncture being located by digital angiography.
