Skin grafting for venous leg ulcers

Area of Science:

• Wound healing research
• Dermatology
• Regenerative medicine

Background:

• Venous leg ulceration is a prevalent and recurring condition affecting up to 1% of adults.
• Standard treatments include dressings and compression, but some ulcers remain unhealed.
• Skin grafts, including autografts, allografts, and xenografts, are explored for recalcitrant ulcers.

Purpose of the Study:

• To evaluate the efficacy of various skin grafting techniques in treating venous leg ulcers.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) identified through Cochrane Wounds Group and Cochrane Central Register.
• Data extraction and quality assessment performed by two independent reviewers.
• Included trials involved participants receiving skin grafts alongside compression bandaging.

Main Results:

• Nine trials with 579 participants were analyzed; most trials were of low methodological quality.
• Bilayer artificial skin (tissue-engineered skin) significantly increased ulcer healing rates compared to simple dressings with compression.
• Insufficient evidence exists to determine the effectiveness of autografts or cultured keratinocyte grafts for venous leg ulcers.

Conclusions:

• Bilayer artificial skin, when used with compression bandaging, improves venous leg ulcer healing rates.
• Further investigation is required to ascertain the benefits of other skin graft types in managing venous leg ulcers.
