ABSTRACT
Step 3. In the case of large tumors, it is often helpful to expose major anatomic structures, such as vessels and nerves proximal and distal to the lesion. This will facili tate their salvage if oncologically feasible. Thus, in the case of a deep thigh sarcoma, the common femoral artery, vein, and nerve are identified cephalad to the tumor, and encircled with vessel loops. Similarly, the superficial femoral vessels are located at the medial aspect of the distal thigh and likewise encircled with vessel loops.
