Use of Amnion Transfer in Resistant Nonhealing Venous Leg Ulcers

In the treatment of venous leg ulcers, after adopting many treatment modalities, at times we are still left with a local indolent problem, "the resistant nonhealing venous ulcer." With repeated surgical procedures failing to obtain a healed ulcer, constant pain, persistent discharging wound, infections, etc., many a patient turn hostile. Also, there comes a dimension of despair in the health feeling of the patient. This prospective study was conducted in 40 patients, who were within the inclusion criteria (January 2006-January 2010, 12 males and 28 females, mean age 45 years). A single amniotic membrane (AM) transfer was done after preparation of the wound, and the parameters were assessed periodically. Follow-up for a minimum period of 1 year in all cases and a maximum period of 3 years in many cases (38) was done. Significant clinical response was defined as an ulcer healing greater than 75 % of the original area. Treatment failure was taken as a persistence or recurrence of more than 25 % of the ulcer area in a 1-year follow-up period. The preliminary results of good ulcer healing and no recurrence are encouraging, even up to 3-year follow-up. This proof-of-concept study demonstrates that AM transfer is useful, safe, inexpensive, readily available, and well accepted by patients, with tremendous potential in promoting epithelial healing in "the resistant nonhealing chronic venous leg ulcer."
