Isotope lymphography of the retrosternal region.

The authors have examined 150 patients with Hodgkin's lymphomas and cancer of the breast and lung. They consider indirect lymphography as a screening method necessary to be completed with available clinical examinations. In normal scintigram it is possible eliminate the pathological process. Even when some part of lymphatic region is not scanned it is possible to say that the suspicion of a pathological process is highly probable. It is necessary to consider the anatomical variability of lymphatic vessels. Therefore, the scintigram must be evaluated together with other clinical findings. The examination of axillar and cervical area of lymphatic system and the determination of eventual collateral circulation is recommended simultaneously with retrosternal lymphography.
