Sartorius myoplasty in the treatment of exposed arterial grafts.

The long-term success of sartorius myoplasty in 14 of 16 patients who presented with an exposed vascular graft in an infected groin is described. The presenting complications were wound dehiscence (ten patients), hemorrhage (two), skin erosion (two), late bilateral fistulas (one) and false aneurysm (one). Ten grafts were prosthetic and six autogenous. Positive cultures were obtained from 15 wounds; four grew Staphylococcus epidermidis, the remainder mixed or Gram-negative bacteria. Each groin was radically debrided, including the surface of the arterial graft, and, if possible, closed immediately with a sartorius myoplasty applied directly to the graft. Twist, fan and loop myoplasties were equally effective. Grossly infected wounds were debrided initially and obviously infected grafts were replaced in situ before myoplasty. Sartorius myoplasty is recommended as an elegant solution for the infected groin in which there is an exposed arterial graft.
