[Complications in reoperations in the popliteal fossa]

For "redo" therapy in the popliteal space an excellent anatomical knowledge is imperative as shown by the results of the dissection of 38 cadaver legs. Dynamic phlebography is the only way to get this information. It is upon this examination that the phlebologist should make his choice either to use sclero-compression therapy or to reoperate the patient. In the case of an reoperation the external access should be chosen even if this implicates an anatomical challenge.
