Abstract

Introduction. Partially avascular wounds pose a challenge to wound care surgeons. Objective. The authors reviewed the literature and institutional results on the use of a dermal regenerative template (DRT) over partially avascular wounds to quantify the ability of the DRT to vascularize over these wounds. Materials and Methods. A review of the literature was performed using Ovid MEDLINE, Google Scholar and Cochrane Library. Patient demographics, comorbidities, wound types, surface area of avascular tissues, and skin graft take were analyzed. A retrospective review of institutional cases was conducted. Results. A total of 32 articles met inclusion criteria. The retrospectiv review included 26 patients with partially avascular wounds reconstructed with the DRT. Seventeen patients experienced 100% graft take 6 experienced partial take, and 3 suffered complete loss. The percent and absolute size of avascular surface area in the wound wa significantly lower in cases of complete graft take compared with partial take and complete loss (1.9% and 2.7 cm2; 9.3% and 10.0 cm2 18.0% and 9.3 cm2, respectively, P < .001). Chronic wound status (P < .001) was significantly associated with less graft take. Conclusions This literature review and retrospective study confirm the DRT is a viable option to provide vascularized coverage over wounds wit avascular components. This study suggests the DRT is more reliable in wounds with less than 1.9% avascular tissues and less successful in chronic wounds.
