Microsurgery: Inguinal Dissection in Rat Model: 7

The fatpad overlying the femoral vessels is lifted over the adductor muscles of the thigh where the proper plane is most easily entered. The incision is carried up onto the abdomen, then along the medial skin flap, creating a U-shaped flap with a lateral base.

The fat pad dissection can be done with Adson forceps and iris scissors. Mobilizing the fat pad laterally, exposes its blood supply, the superficial epigastric artery. The tiny terminal branches of this vessel around the periphery of the fat pad usually do not require cautery. The epigastric vessels originate from the femoral vessels which can be seen in the base of the field.

A retractor is now placed in the muscles of the abdominal wall, exposing the white inguinal ligament and the full length of the femoral vessel segment to be used. The fat pad is kept moist with a wet sponge. The femoral vessels are 600-800 microns (0.6-0.8mm), slightly smaller than human digital vessels. If one can create a perfect, patent anastomosis in these vessels, one is well on the way to attaining clinical competence. In addition, the rat is hypercoagulable, making the learning process more rigorous and demanding.
