[Transvenous xerotom-angiography of the pulmonary hilus (author's transl)].
Normal-size lymph-nodes and air-filled bronchi do not contribute significantly to the shadow of the normal hilus. This consists mainly in pulmonary arteries and veins of the upper lobes. Any enlargement beyond the vascular shadow has to be considered as pathologic. Xerotom-angiography following injection of contrast medium into the cubital vein shows the pulmonary vessels near the hilus more clearly. Pulmonary arteries towards the truncus are better shown. This improves the clarity of the hilus. Coincident demonstration of the superior vena cava may show pathologic processes in the upper mediastinum.
