Thrombophilia and chronic venous ulceration

Area of Science:

• Vascular Medicine
• Hematology
• Dermatology

Background:

• Thrombophilia (TP) is a known risk factor for deep venous thrombosis (DVT).
• Deep venous thrombosis (DVT) is a significant predisposing factor for chronic venous ulceration (CVU).
• The direct relationship between TP and CVU remains under-investigated.

Purpose of the Study:

• To investigate the prevalence and implications of thrombophilia in patients with chronic venous ulceration.
• To explore the potential mechanisms linking thrombophilia to chronic venous ulceration.
• To highlight the need for reconsidering diagnostic and management strategies for venous diseases.

Main Methods:

• Literature review of studies investigating thrombophilia in patients with chronic venous ulceration.
• Analysis of the prevalence of TP in CVU cohorts compared to DVT cohorts.
• Discussion of potential pathophysiological links between TP and CVU.

Main Results:

• The prevalence of thrombophilia in patients with chronic venous ulceration is notably high.
• This prevalence is comparable to that observed in patients with a history of deep venous thrombosis.
• A significant proportion of CVU patients with high TP prevalence lacked clear DVT history or duplex evidence.

Conclusions:

• Thrombophilia may be an independent risk factor for chronic venous ulceration, potentially acting through macro- or micro-vascular thrombosis.
• The findings necessitate a re-evaluation of the diagnostic workup for CVU patients, considering TP screening.
• Improved understanding of the TP-CVU link can inform targeted prevention and management strategies for patients with venous disease.
