Abstract
Background: Specific perforator-based
flaps are a new era in plastic reconstruction. They have replaced many of the
traditional paradigms in plastic surgery. The anteromedial thigh flap is a
versatile flap that can be used as a primary choice for many reconstructive
purposes or as a secondary choice for the anterolateral thigh flap. Mapping the
vascular territory of anteromedial thigh is essential for the proper design of
the flap.
Aim of the work: The aim of this work was to
study the cutaneous perforators of the anteromedial thigh and explain their
significance in flap design.
Material and
methods: The
material of this study included 30 fresh cadaveric lower limbs. The external
iliac artery was injected with colored latex. Superficial and deep dissections
were undertaken under a magnifying lens to locate the per-forators and identify
their type. The length and diameter of the perforators were measured.
Results: Anteromedial thigh skin was
divided into 6 squares. Squares 1 and 4 are the upper squares and comprise the
skin over the upper medial thigh. It is primarily based on the superficial
external pudendal artery, deep external pudendal artery, and superficial
circumflex femoral artery. Squares 2 and 5 are the middle squares and were
mainly supplied by perforators of the superficial femoral artery. Squares 3 and
6 are the lower squares and were mainly supplied by the saphenous artery and
superficial femoral artery. The possible flap designs are then discussed.
Conclusion: The anteromedial thigh skin is
richly supplied by a mixture of per-forators from multiple sources. The
segmental nature of the perforators arising from the superficial external
pudendal artery, deep external pudendal artery, superficial femoral artery, and
saphenous artery together with the long course and large diameter of
perforators grant the anteromedial thigh flap its versatility.
Biography
Habiba Elshennawy is an
aspiring postgraduate student. She is specifically interested in applied
anatomy for reconstructive surgery. She had her master’s degree in surgical
anatomy of perforator flaps from the thigh. She finished her master’s degree at
the age of 29 and her MRCS at 27. She has international publications in both
anatomy and surgery journals.
