AVF Session: Wound Healing, Edema, and Ulcer Outcomes Research

Monitoring Compression Pressure and Diagnosing Phlebolymphedema

A wireless multipoint pressure sensor showed that compression bandages frequently fall outside their target range and lose pressure over the day, even with guided application, though higher initial pressure reduced time spent below target. CT scanning of skin, subcutaneous, and muscle compartment changes also showed strong sensitivity for phlebolymphedema, with honeycombing the most reproducible finding.

Nutrition, Immunocompetence, and Outcome Measurement

A prognostic nutritional index combining albumin and lymphocyte count predicted slower initial healing and higher one-year recurrence of venous leg ulcers. Separately, a systematic review found that randomized lymphedema trials rarely designate a primary outcome measure or perform a power calculation, complicating comparisons across studies.

Applying Ulcer Trial Evidence and Testing Skin Substitutes

A Midwest wound center population with higher obesity and diabetes rates than the ESCHAR and EVRA ablation trials did not show the same ulcer healing benefit from early ablation. A randomized trial of a decellularized dermis allograft added to compression therapy found no significant improvement in ulcer healing or recurrence at twelve weeks.
