[External retromalleolar lymphography of the superficial and deep lymphatics of the lower limb (author's transl)].

External retromalleolar lymphography was employed to explore lower limb lymphatics in 39 patients. Though this type of approach enables deep lymph vessels of the thigh to be studied--at the price of a more difficult catheterization than when the classical approach is used--it is ineffective for demonstrating deep lower leg lymph vessels, filling occurring only in the superficial network. Its indications are therefore limited to cases following unsuccessful attempts with the classical approach.
