Abstract

Background: The cutaneous perforrator flap is one of the important materials in plastic surgery, revealing these branches remains a challenge for surgeons. In order to understand clearly about the cutaneous branches of the deep femoral artery, the flaps which are very useful in surgery to cover the defects of the ischium tuberosity, greater trochanter region, we conduct research on the subject: “Anatomical study perforator of deep femoral artery by cadaver dissection” Materials and methods: Study of prospective, cross section and series case. Sample study on 17 cadavers were impregnated with formol and stored in cold room include 31 cutaneous posterior thigh flaps. On the cadaver the penetrating branches of the deep femoral artery were disseted according to a unified procedure. The limit skin incisions to discover perforators of deep femoral artery are superiorly: horizontal line across the inferior gluteal fold, inferior: from line across popliteal fossa laterally: a  line connecting frome lateral condyle of femur to greater trochanter, medially: a  line connecting frome inferior pulic ramus to medial condyle of femur. Discover the perforator branches of deep femoral artery. Measure anatomical landmarks and size of perforator branches by using Palmer ruler. Results: Branches I and II appear mostly in 1/2 superior reference line with a distance of about 3cm on both sides of reference line. Branch I have a occurence frequency on the lateral side of reference line is 7 times more than (27 vs. 4) medial side reference line in both side. The perforator IV was found 5 cas on lateral thigh, in which smallest rate 16.13%. The perforator has a diameter of 1-2mm accounting for a high proportion, in which the branch I accounts for the highest rate 54.83%. The perforator has the length of 15-30mm accounting for a high proportion, especially of the branch I and II (64.52% and 70.97%). The average distance from perforator I to greater trochanter is 157.39 ± 38.12 mm and to ischium is 127.93 ± 37.87mm. Conclusion: The perforator flaps of deep femoral artery are suitable for plastic surgery to cover the ischium and greater trochanter defects.
