Selecting the incision Site
There are several factors to consider when selecting the inci-
sion site, such as operator preference, number of grafts need-
ed, and whether the upper or lower leg is used for the vein
harvest.
There are two commonly used incision sites (Figure 6):
Below the knee: Palpate along the tibia until reaching the
medial tibial epicondyle. Make a 2 cm incision along the
posterior border of the tibial epicondyle. (Figure 7)
Above the knee: Make a 2 cm incision in the thigh where the
vein lies in the groove between the sartorius and gracilis
muscles. (Figure 8)
Making the incision
Once the site has been identified, make a 2 cm skin incision
directly over the vein.
A transverse, longitudinal or oblique incision may be used
depending on operator preference.
Under direct visualization, dissect the subcutaneous tissue
to expose the greater saphenous vein.
Continue dissection of the anterior surface of the vein in the
direction of planned harvesting, creating a small space
approximately the length of the distal end of the BTT to
ensure easy insertion.
