- Abstract
- Although the saphenous flap has been used in reconstruction as a
free flap, there has not yet been an anatomic study about the perforators of
the saphenous artery. The aim of this study is to investigate the anatomy of
the saphenous artery and the number and locations of its perforators. We
dissected parts of 10 legs from 5 cadavers. Measurements of the positions of
the dissected saphenous arteries and their perforators were taken from the
medial epicondyle of the femur. We observed the origin, end point, and the
diameter of each of the arteries, and we investigated the numbers and
locations of both septocutaneous and musculocutaneous perforators. The
average length of saphenous artery was 14.8 cm, and it was located 12.0 cm
above the medial epicondyle of the femur. The average diameter was 1.63
mm. A median average of 4 perforators branched out from a single saphenous
artery. There was a median average of 2 septocutaneous perforators and
2 musculocutaneous perforators from the saphenous artery. The perforators
were mainly located at 7 cm proximal to the medial epicondyle of the femur.
The saphenous artery has many perforators and is therefore useful as the
pedicle of the perforator flap. The saphenous artery perforator flap can be
designed within 7 cm proximal to the medial epicondyle of the femur. Our
results may be helpful in the applications of the neurocutaneous flap using
the saphenous artery or the perforator flap based on septocutaneous perforators.
Key Words: saphenous artery, neurocutaneous flap, perforator flap
