[Pathogenesis of therapy refractory ulcus cruris]

Area of Science:

• Vascular Medicine
• Dermatology
• Wound Healing

Context:

• Chronic leg ulcers are a significant clinical challenge, often associated with underlying vascular pathologies.
• Chronic venous insufficiency (CVI) is frequently implicated, but other etiologies can coexist.
• Understanding the multifactorial nature of these ulcers is crucial for effective management.

Purpose:

• To investigate the diverse etiologies of chronic, non-healing leg ulcers in hospitalized patients.
• To determine the prevalence of CVI and other contributing factors such as arterial disease, vasculitis, polyneuropathy, and diabetes mellitus.
• To highlight the necessity of thorough diagnostic workups for complex leg ulcers.

Summary:

• A study of 101 inpatients revealed CVI in 95% of cases, but isolated venous disease was present in only 17%.
• The majority of patients (92%) exhibited combined arterial and venous disease, with 74% having confirmed arterial disease.
• Multiple etiologic factors (two or three) were common, underscoring the complexity of non-healing leg ulcers.

Impact:

• This research emphasizes that non-healing leg ulcers frequently stem from multiple causes.
• It underscores the critical need for comprehensive diagnostic strategies to identify all contributing factors.
• Accurate diagnosis of multifactorial leg ulcers is essential for guiding appropriate treatment and improving patient outcomes.
