In this simplification of the technique for lymphangiography, a thin metal blade can be used to elevate the lymph duct to the level of the skin surface. If a flat skin surface has been chosen for the incision site, the cannulating needle can be held flat against the skin surface, where it will be in direct alignment with the lymph duct. In this stabilizing position, the needle need only be advanced proximally to insert it into the lumen of the lymph duct. Sterile tape is used to hold the needle in this position so that both hands are free to tie the needle in place.
This modified technique has considerably reduced the radiologist's time needed to cannulate lymphatic ducts for lymphangiography.
