RESUMEN
El colgajo supramaleolar lateral es un colgajo fasciocutáneo que se realiza en el tercio distal lateral de la pierna, y que tiene como pedículo vascular la rama perforante de la arteria peronea y también es irrigada por la arteria maleolar anterolateral, la arteria tarsal del pie, por medio de sus anastomosis amplias. El objetivo de estudio es identificar las características anatómicas del colgajo, su vascularización, arco de rotación y áreas de cobertura habiéndose realizado la disección de 15 piezas anatómicas que cumplían con los criterios de inclusión en el estudio. Los resultados del estudio se halló la presencia constante de la rama perforante de la arteria peronea, a nivel del ángulo tibioperoneo. Siendo la longitud de la rama perforante de la arteria peronea de 0.86±0.14cm, la longitud promedio de la arteria maleolar anterolateral de 2.9cm, la longitud promedio de la arteria lateral tarsal es de 5.2cm, siendo el número de ramas superiores de la rama perforantes de la arteria peronea como promedio de 2.1cm, la longitud promedio del mismo es de 3.7cm, el número promedio de ramas inferiores de la rama perforante de la arteria peronea es de 1.4, siendo su longitud promedio de 4.5cm. La distancia promedio del maléolo externo a la emergencia de la rama perforante de la arteria perones es de 4.7cm, la distancia promedio de la rama perforante de la arteria peronea al ángulo tibio peroneo es de 1.2cm, siendo la longitud promedio del pedículo de flujo directo de 0.86cm, la longitud del pedículo con flujo inverso preservando la arteria maleolar anterolateral es de 4.5cm, y preservando la arteria lateral tarsal en promedio es de 8.5cm, siendo la distancia de la rama perforante de la arteria peronea a la arteria maleolar anterolateral de 4.5cm y de la arteria maleolar anterolateral a la arteria lateral tarsal de 1.76 cm. Los resultados concuerdan con los encontrados por Masquelet en su trabajo, por lo que se mantiene el concepto de la escasa variación anatómica en...
ABSTRACT
The lateral supramalleolar flap is an fasciocutaneus flap that takes place in the distal third part of the leg, and whose vascularized by branches of a perforating branch of the peroneal artery, and also is vascularized by antero lateral maleollarartery, by tarsal lateral artery, throught its wide anastomoses. The objective of the study is to identify the anatomical characteristics of the flap, its vascularization, are rotation, the pivot point, and coverage areas, having performed anatomical dissection of 15 pieces that meet the criteria for inclusion in the study. Study results in the constant presence of the perforating branch of the peroneal artery, emerging in tibioperoneal angle. The length of the perforating branch of the dorsal peroneal artery was 0.86±0.14cm, the average lenght of the anterolateral malleolar artery 2.9cm, the average lenght of the tarsal lateral artery was de 5.2cm, and the average number of ascending branches of the perforating branch of the dorsal peroneal artery was 2.1,and its average lenght was 3.7cm, the average number of lower branches of the perforating branch of the peroneal artery is 1.4 ,and its average length 4,5cm. The average distance between external side malleolar and perforating branch of peroneal artery is 4.7cm, the average distance between the perforating branch of peroneal artery and tibioperoneal angle is 1.2cm, and the average lenght of the pedicle of direct flow is 0.86cm, the average lenght of the backflow pedicle, preserving the anterolateral malleolar artery is 4.5cm, and preserving the tarsal lateral artery in average is 8.5cm, being the distance between the perforating branch of peroneal artery and the anterolateral malleolar artery of 4.5cm, and between the anterolateral malleolar artery and tarsallateral artery of 1.76 cm. The results agree with those found by Masquelet at work so the concept of the limited variation in anatomical dissection of the lateral supramalleolar flap is maintained.
