Venous Ulcers of the Lower Extremities: Current and Newer Management Techniques:

Diagnosis and treatment of venous leg ulcers

Treatment for venous leg ulcers has been extensively researched and well defined. The primary care practitioner who is able to recognize and appropriately treat these patients can help prevent months and sometimes years of suffering.

Giving information on compression to patients with venous leg ulcers

Venous leg ulceration is a common condition that is more likely to affect the elderly (Alexander House Group, 1992; Coupe and Walukiewicz, 2000) and often has a psychological, as well as physical, impact on the individual (Charles, 1995). Many of those affected are cared for within the community (Maylor, 2002) and may become isolated because of the difficulties caused by their condition (Charles, 1995). Compression bandaging therapy has been shown as an effective treatment for venous leg ulcers (Loftus and Wheatley, 2000) but the bandages must be worn continually during treatment and therefore need to be socially and psychologically acceptable if the patient is to be happy with the treatment regimen (Pudner, 1998). Nurses need to be competent in the care of leg ulcers so that pain and discomfort are minimized and patients need to be willing to accept the treatment given.

Factors that influence healing in chronic venous ulcers treated with cryopreserved human epidermal cultures

BACKGROUND

Cryopreserved epidermal cultures (CEC) offer an "off the shelf" treatment for chronic wounds. These cultures are derived from neonatal foreskin and grow rapidly in vitro to form epidermal sheets. They do not require a biopsy from the patient, an advantage compared to autografts. They seem to act as a biological dressing, stimulating epithelialization from the wound edges and adnexae, probably through growth factor release.

OBJECTIVE

To summarize our recent experience with the use of CEC in chronic venous leg ulcers and to determine the factors that influence healing in chronic venous ulcers treated with CEC.

PATIENTS AND METHODS

A single arm, open label study including a total of 11 patients with documented venous ulcers was performed. The study involved the application of cryopreserved epidermal cultures every other week to nonhealing leg ulcers for a total of 12 weeks or until complete healing of the ulcer.

RESULTS

A total of 11 patients with one or more leg ulcers were treated. The average age was similar in healed and unhealed groups. Seven patients completely healed after an average of 4.14 CEC applications. Four patients did not heal after a total of 12 CEC applications.

CONCLUSION

Predictors for failure to heal after CEC application in our patients were long wound duration, wound size, presence of lipodermatosclerosis, and history of failed prior split-thickness skin grafts.
