“…ALT flap thickness was also studied by Set et al using computed tomographic angiograms in 98 patients, taking BMI, gender, and ethnicity into consideration (Seth et al, 2011). They encountered values ranging from 9.9 ± 5.1 to 19.9 ± 11.3 mm, depending on gender and BMI, which shows reasonable agreement with the findings presented here.…”

Background:Anterolateral thigh (ALT) flap is one of the most common flaps in the reconstruction armamentarium of plastic surgeons, but there is no published data about the flap characteristics in the Indian population. The aim of this study is to analyse the anthropomorphic characteristics of the ALT flap and the perforator details in Indian population.Materials and Methods:ALT flap details were studied in 65 patients of Indian origin comprising 45 males and 20 females. The study period is from August 2011 to July 2012. A prospective database of the Doppler findings, perforator and pedicle details and the flap morphology were maintained. The variables are analysed by using the SPSS, PASW statistics 18 software IBM®.Results:In nearly 75% of cases, the perforator was found within 4 cm of the pre-operative Doppler markings. The percentage of musculocutaneous and septocutaneous perforators was 61.8% and 38.2% respectively. The pedicle variation was found in 6 cases (9.23%). The average thickness of the thigh skin in Indians is similar to the western people, but thicker than the other Asian people. Flap thinning was performed in nine patients without any major complications.Conclusion:The perforator details and type in the Indian population are similar to the published reports from other parts of the world. We advise pre-operative Doppler examination in possible cases. The variation in pedicle anatomy should not be overlooked to avoid complications. The thickness of subcutaneous tissue of the flap is higher in Indians, but still can be safely thinned. The data of this study will serve as a guide for the ALT flap characteristics in Indian patients.

“…4 These perforators originate from the LCFA, which has a variable anatomic origin from the femoral artery 7 ( Figure 2). Most frequently, the LCFA originates directly from the deep femoral artery and second most frequently from the common femoral artery (10-25%) or even more proximally from the external iliac artery (6%).…”

The anterolateral thigh (ALT) flap has widespread use throughout the body because of the many engineering options. The ALT has a complex local vasculature, which can be of importance for the surgical approach. In general, the flap receives its perfusion from branches of the lateral circumflex femoral artery (LCFA). The LCFA, however, has a large anatomic variance. CT angiography can guide the surgeon in the selection of the most suitable site and aid in the surgical approach.
