INTRODUCTION Since the introduction by Song and colleagues in 1984, the anterolateral thigh flap was described for head and neck scars in patients with burns 1 , it has become popular and very accepted by their versatility, ideal for numerous reconstructions, with minimal morbidity in the donor site. 1,2 The anterolateral thigh flap could be designed as myocutaneous ( including the rectus femoral, the vastus lateral or the tensor of the fascia lata), fasciocutaneous, adipofascial or inclusive suprafascial. 3 It could be a simple or mixed flap, their dissection allows us to create a free or pediculate flap, or inclusive a neurocutaneous flap including the femoral lateral cutaneous nerve 3,4 . Between the benefits of this flap are their length of 4-35cm with a median of 16cm, width of 4-25 cm with a median of 8cm, thickness of 0.5 - 2.8 cm with a median of 0.64cm, the extension of body surface is between 70 – 240cm 2 (with a *Corresponding Author: Alejandra Lizbeth Salinas Atriano, General Surgeon, Medical Student, Hospital General de Zona #30 IMSS, México City, Mexico. Abstract Objective: To determine the vascular variability in Mexican population submitted to anterolateral thigh flap. Material and Methods: We performed a retrospective, transversal analysis of patients submitted to medial thigh lift in the Hospital General de México during the period from 2013 to 2016. Of a total of 95 patients with this procedure, only 45 complete the inclusion criteria and were analyzed in their clinical and arteriography characteristics, with posterior statistical analysis with Stata 11.1 software. Results: Of the 95 patients with medial thigh lift, 40 were excluded. Of the remaining 45 patients, 35 were males and 10 females. The statistical analysis found that perforating A type was the most common in females, while B was the most common in males according to the classification of Yu. Other analyzed variables include the length of the perforating vessels, with type A of 21.85mm, perforating B of 25.27mm and the perforating C of 34.8mm; and the diameter of perforating A of 2.84mm, B of 2.46mm and C of 2.15mm. Conclusions: with this advanced comprehensive anatomy of the vascularity in the anterolateral thigh region we showed that is possible to increase the length and diameter of the incision of the anterolateral thigh lift with no significant increase in risk; specially with perforating type A, that is more common in females, as this procedure continues being the most popular and used due to its functional and cosmetic results.
