Delayed Healing

AbstractArea analysis of thermal images can detect delayed healing in diabetes foot ulcers, but not venous leg ulcers (VLU) assessed in the home environment. This study proposes using textural analysis of thermal images to predict the healing trajectory of venous leg ulcers assessed in home settings. Participants with VLU were followed over twelve weeks. Digital images, thermal images and planimetry of wound tracings of the ulcers of 60 older participants was recorded in their homes by nurses. Participants were labelled as healed or unhealed based on status of the wound at the 12th week follow up. The weekly change in textural features was computed and the first two principal components were obtained. 60 participants (aged 80.53 ± 11.94 years) with 72 wounds (mean area 21.32 ± 51.28cm2) were included in the study. The first PCA of the change in textural features in week 2 with respect to week 0 were statistically significant for differentiating between healed and unhealed cases. Textural analysis of thermal images is an effective method to predict in week 2 which venous leg ulcers will not heal by week 12 among older people whose wounds are being managed in their homes.

Objectives This is a retrospective study over 12 years reporting the healing rates of leg ulcers at a specialist vein unit. All patients presented with active chronic venous leg ulcers (clinical, aetiological, anatomical and pathological elements [CEAP]: C6) and had previously been advised elsewhere that their ulcers were amenable to conservative measures only. Method Seventy-two patients (84 limbs) were treated between March 1999 and June 2011. Patients were contacted in August 2011 by questionnaire and telephone. Of 72 patients, two were deceased and two had moved location at follow-up, so were not contactable. Fifty patients replied and 18 did not (response rate 74%), representing a mean follow-up time of 3.1 years. Results Ulcer healing occurred in 85% (44 of 52 limbs) of which 52% (27) limbs were no longer confined to compression. Clinical improvement was achieved in 98% of limbs. Conclusions This study shows that a significant proportion of ulcers currently managed conservatively can be healed by surgical intervention.

Meta Regression Analysis

Objective The aim of this analysis was to perform a meta-analysis evaluating gender difference of delayed healing risk in patients with venous leg ulcers. Methods We searched the PubMed and Web of Knowledge from their inception to 4 July 2015. The meta-analysis of pooled odds ratio and 95% confidence interval for venous leg ulcers healing risk were calculated. Results Twelve studies with 4453 patients were included in the meta-analysis. The pooled odds ratio for healing rate stratified by gender was 1.055 (95% CI 0.955–1.165; Z = 1.05, p = 0.292) by fix-effects model. The Begg's test (z = 2.67, p = 0.007), the Egger's test (t = 4.00, p = 0.003), and asymmetric funnel plot suggested there was significant publication bias. Subgroup analysis showed the pooled odds ratios were 1.048 (95% CI 0.945–1.162; Z = 0.88, p = 0.376) in prospective studies and 1.439 (95% CI 0.757–2.736; Z = 1.11, p = 0.266) in retrospective studies. Sensitivity analyses by only pooled adjusted odds ratios showed the pooled odds ratio was 1.049 (95% CI 0.946–1.163; Z = 0.91, p = 0.365), which indicated the results of meta-analysis were robust. Meta-regression analysis showed the healing rate odds ratio stratified by gender was not related with healing rate (t = 0.73, p = 0.484). Conclusion Our meta-analysis indicates that no gender difference existed for delayed healing in venous leg ulcers. Our results may be also useful in developing a risk score for failure of venous leg ulcers to heal.

Potential Risk Factors

Objective: To identify independent risk factors for delayed healing and increased recurrence of chronic venous leg ulcers. Design: Prospective study. Setting: Community-based leg ulcer service. Patients: Six hundred and thirty-three limbs in 587 consecutive patients with an ankle-brachial pressure index (ABPI) ≥0.85. Method: Potential risk factors were initially assessed in a one-stop clinic incorporating clinical evaluation, ABPI and venous duplex imaging. Limbs were treated within a defined protocol. Twenty-four-week healing and 3-year ulcer recurrence rates were determined. Results: Of 12 potential risk factors age ( p< 0.001), ulcer chronicity ( p< 0.001) and popliteal vein reflux ( p< 0.005) were independent risks for delayed healing. Of 13 potential risk factors rheumatoid arthritis ( p<0.005) and healing time ( p < 0.05) were independent risks for ulcer recurrence. Isolated superficial venous reflux treated by saphenous vein surgery predicted reduced ulcer recurrence ( p< 0.005). Conclusion: Targeting in primary care of ulcer patients with specific characteristics might encourage earlier referral and appropriate resource management. Leg ulcer patients with superficial venous reflux might benefit from surgical correction.
