patient positioning

Place the patient in a supine position. Externally rotate the leg
with the knee flexed and with support behind the knee and
the thigh. (Figure 1)

Surgical preparation and Vein location

Prior to the skin prep, assess the patient to select the incision
site around the knee area. Once the intended incision site is
identified, mark the area with a surgical marker.

The saphenous vein can usually be found by using anatomical
landmarks. For morbidly obese patients, an ultrasonic
doppler may be used to help locate the vein. If needed, use
the doppler prior to the patient prep and then mark the site
with a surgical marker. If appropriate, vein mapping may be
performed preoperatively. Note that the saphenous vein in
its natural position lies fairly posterior in relationship to the
patella. Perform skin prep according to hospital protocol.
