Management of venous ulcers.

Area of Science:

• Vascular Medicine
• Dermatology
• Epidemiology

Background:

• Venous ulcers are traditionally considered the primary cause of leg ulcers in Western countries, with estimates historically ranging from 80-90%.
• The increasing prevalence of combined venous and arterial disease, potentially due to improved diagnostics and an aging population, necessitates updated epidemiological data.

Purpose of the Study:

• To investigate the current prevalence and etiological distribution of leg ulcers, focusing on the proportion attributable to venous insufficiency.
• To analyze the relationship between chronic venous ulcers and demographic factors such as age and sex.

Main Methods:

• Cross-sectional survey in a Swedish population to determine ulcer etiology and prevalence.
• Screening of a large Australian population (238,000 individuals) to identify chronic ulcers and assess venous abnormalities.
• Statistical analysis to compare prevalence rates and examine age and sex differences.

Main Results:

• In Sweden, 54% of ulcers were purely venous, with a population prevalence of 0.16%.
• In Australia, venous abnormalities were found in 57% of chronic ulcer cases, yielding a population prevalence of 0.06%.
• The prevalence of chronic venous ulcers increased with age, with no significant sex-based differences observed.

Conclusions:

• While venous ulcers remain a significant cause of leg ulceration, current data suggest their prevalence may be lower than previously reported.
• Age is a key risk factor for chronic venous ulcers, highlighting the impact of population aging on vascular health.
• Further research is warranted to understand the evolving epidemiology of leg ulcers and associated risk factors.
