La infección protésica inguinal es una complicación grave que pone en riesgo la extremidad revascularizada, y su solución resulta compleja en muchas ocasiones, incluso en las mejores situaciones.
Caso clínicoVarón de 56 años con varias cirugías revascularizadoras en ambos miembros inferiores y ausencia de vena autóloga. Presenta antecedente de infección precoz en una prótesis femoropoplítea tratada con retirada parcial. Acude por infección inguinal con bypass femoropoplíteo infragenicular compuesto (politetrafluoroetileno-vena safena interna) permeable. Se realizó un amplio desbridamiento de la zona, con la retirada de la prótesis residual, y se implantó un bypass ortoanatómico con aloinjerto arterial criopreservado y posterior cobertura con flap muscular rotacional (recto anterior-sartorio) e injerto cutáneo parcial. Visto en una revisión a los tres meses con permeabilidad del bypass y buena integración del injerto.
ConclusiónEn caso de infección protésica, asociada a gran afectación tisular, y ausencia de material autólogo para su sustitución, el empleo de un aloinjerto arterial criopreservado con posterior cobertura con un flap muscular y cutáneo se presenta como una opción válida en su manejo.
Inguinal graft infections constitute a severe complication that puts the revascularised limb at risk and they are often difficult to resolve, even in the best situations.
Case reportA 56-year-old male who had previously undergone several revascularisation operations in both lower limbs and had no autologous veins. The patient had previously suffered early infection of a femoral-popliteal graft which was treated by means of partial withdrawal. He visited because of an inguinal infection with a compound (polytetrafluoroethylene-great saphenous vein) below-theknee femoral-popliteal bypass that was seen to be patent. The procedure consisted in wide debridement of the area, with removal of the residual graft, and an anatomic bypass was implanted with a cryopreserved arterial allograft and later covered with a rotational muscular (rectus femoris-sartorius) flap and partial skin graft. In a control visit at three months, the bypass was seen to be patent and the graft was well integrated.
ConclusionsIn cases of infection of a prosthetic graft, associated with widespread tissue involvement, and the absence of autologous material with which to replace it, use of a cryopreserved arterial allograft that is later covered with a muscle and skin flap has proved to be a valid management option.
