Management of Postfasciotomy Wounds and Skin Defects Following Complex Vascular Trauma to the Extremities Using the...

Management of large postfasciotomy wounds and/or skin and soft tissue defects after major vascular trauma to the extremities can be challenging. The External Tissue Extender (Blomqvist; ETE), a skin-stretching device, which consists of silicone tapes and plastic stoppers, approximates wound margins and facilitates delayed primary closure. We describe our experience with the use of ETE in 5 patients (4 males) with a total of 8 wounds (7 postfasciotomy, 1 soft tissue defect) over the past 12 years. The mean patient age was 32 (range 17-61) years. The wounds involved the lower limb in 3 patients and the upper limb in 2, whereas the injured arteries were the popliteal in 3, the axillary in 1, and the brachial in 1. The mean wound length was 24 cm (range 9-37 cm), and the mean number of ETE silicone tapes used per wound was 13 (range 5-19). The median duration of ETE therapy was 7 days (range 4-7). ETE therapy resulted in sufficient wound approximation to allow complete closure with conventional suturing in 7 out of the 8 wounds. Of these, one developed infection that required drainage, debridement, and resuturing. All wounds achieved satisfactory healing status and all limbs had been salvaged. In conclusion, the ETE is a useful, easy-to-use, and simple adjunct that may facilitate delayed primary closure of large postfasciotomy wounds or extensive skin and soft tissue defects following complex vascular trauma to the extremities.
