Prevention and treatment of thromboembolism: diagnosis by roentgenology (author's transl)

Abstract

In 30% of our patients, thrombotic disease was an indication for phlebography. Visualization of veins was performed preferably by taking X-ray films of the ascending contrast medium. The radiologic findings of the acute stages include filling defects, irregular margins, and convex delineation. Post-thrombotic signs include lesions of the valves, recanalization, and collateralization. In cases of occluded inferior vena cava and axillary vein (Paget-von Schroetter Syndrome) collateral circulation occurs. In 80% of cases, phlebography provides important information following medical or surgical therapy.
