Pelvic phlebography is an X-ray examination of the pelvic veins using a contrast agent. It is carried out in case of suspected developmental abnormalities, acute thrombosis, post-thrombotic disorders and other pathological conditions of the pelvic and inferior vena cava veins. It is used to assess the prevalence of malignant neoplasia of the pelvic organs. Usually, contrast is injected into the femoral vein by puncture or catheterization. According to indications, during pelvic phlebography, it is possible to use other veins, simultaneous bilateral administration of a contrast agent, and the introduction of contrast into the bone marrow. After filling the venous system, a series of radiographs are performed.
