Treating Wounds With an Avascular Component With a Dermal Regenerative Template

Area of Science:

• Regenerative Medicine
• Wound Healing
• Tissue Engineering

Background:

• Partially avascular wounds present significant challenges in surgical wound care.
• Effective vascularization is crucial for successful wound healing and graft survival.

Purpose of the Study:

• To evaluate the efficacy of the dermal regenerative template (DRT) in promoting vascularization over partially avascular wounds.
• To quantify the success rate of DRT in different avascular wound scenarios.

Main Methods:

• A comprehensive literature review was conducted using Ovid MEDLINE, Google Scholar, and Cochrane Library.
• A retrospective analysis of 26 patients treated with DRT for partially avascular wounds at an institution was performed.
• Key metrics analyzed included patient demographics, comorbidities, wound characteristics, avascular surface area, and skin graft take.

Main Results:

• The study analyzed 32 articles and 26 patient cases.
• 100% skin graft take was achieved in 17 patients, with partial take in 6 and complete loss in 3.
• Lower avascular surface area (<1.9%) and absence of chronic wound status were significantly associated with successful graft take (P < .001).

Conclusions:

• The dermal regenerative template (DRT) is a viable option for achieving vascularized coverage in wounds with avascular components.
• DRT demonstrates higher reliability in wounds with minimal avascularity (<1.9%) and is less successful in chronic wound cases.
