Colgajo de perforante de la arteria tibial posterior. Serie de casos. [Posterior tibial artery perforator flap. Case series]

Introduction: Coverage defects in the leg are a challenge due to the particulars of the anatomy in said area, different reconstruction strategies have been developed, being the fasciocutaneous perforator flaps the most frequently used. The aim of this paper is to discuss the therapeutic alternative and to describe the surgical technique, the results and the complications of the posterior tibial artery perforator flap (PTAPF) to treat coverage defects.Materials and Methods: We performed a retrospective review of patients treated with a fasciocutaneous flap. We analyzed preoperative demographic variables. The surgical technique and the indications in each patient are described. Finally, the postoperative variables, such as complications and flap survival, were analyzed.Results: Twelve patients (all male) treated with PTAPF were included. The average age at the time of surgery was 52 years (range: 29-77 years). The maximum follow-up was 55 months, with a minimum of 5 months (average: 18 months). There were two flaps with transient congestion that reverted spontaneously: one partial failure and one total failure.Conclusions: PTAPF should be considered a viable option for the treatment of small- and medium-sized leg wounds, since they provide similar tissue thickness, texture and color on the recipient site, achieving good clinical and cosmetic results.Introducción: Los defectos de cobertura en la pierna son un problema difícil de solucionar debido a las características propias de la región anatómica. Por ello, se han desarrollado distintas estrategias de reconstrucción, y los colgajos de perforante fasciocutáneos son los que se utilizan con más frecuencia.Objetivos: Presentar la alternativa terapéutica, describir la técnica quirúrgica, los resultados y las complicaciones del colgajo de perforante de la arteria tibial posterior para el tratamiento de defectos de cobertura en la pierna.Materiales y Métodos: Se realizó una revisión retrospectiva de los pacientes tratados con colgajo fasciocutáneo en la pierna y operados en nuestro Centro. Se analizaron variables demográficas preoperatorias. Se describen la técnica quirúrgica y las indicaciones en cada paciente. Se analizaron variables posoperatorias, como las complicaciones y la supervivencia del colgajo.Resultados: Se incluyeron 12 hombres tratados con colgajo de perforante de la arteria tibial posterior.El promedio de edad en el momento de la cirugía fue de 52 años (rango 29-77). El seguimiento máximo fue de 55 meses y el mínimo, de 5 meses (promedio 18). Hubo dos colgajos con sufrimiento transitorio, una falla parcial y una falla total.Conclusiones:El colgajo de perforante de la arteria tibial posterior ha de ser considerado una opción válida en el tratamiento de heridas de pequeño y mediano tamaño de la pierna. Provee de tejido similar en grosor, textura y color en el sitio receptor con buenos resultados clínicos y estéticos.
