1 From the Department of Radiology, University Hospital, Leiden, The Netherlands
In 15 per cent of our lymphographic examinations, filling with contrast medium of the lymph nodes was insufficient for complete evaluation.
The main limitations were : (1) nonvisualization above a complete blockage or impairment of drainage; (2) nonvisualization presenting as an interruption of a lymph node chain; and (3) poorly filled lymph nodes, which could not be evaluated accurately even on laminagrams.
Selective angiography (phlebography, cavography) often provided important data on the doubtful areas in such instances.
In a department where lymphography is practiced, supplementary angiography is indispensable.
