Insights
Thrombophilia, including factor VIII deficiency, is more common in young patients with chronic venous insufficiency. Investigating coagulopathy can aid in managing venous leg ulcers and preventing recurrence.
Area of Science:
- Vascular Medicine
- Hematology
Background:
- Chronic venous disease (CVD) affects millions globally, with venous valvular incompetencies and reflux as key contributors.
- Increased prevalence of thrombophilia is observed in patients with chronic venous insufficiency (CVI).
Purpose of the Study:
- To highlight the importance of thrombophilia screening in young patients presenting with venous disease.
- To emphasize the role of factor VIII deficiency in the context of CVI and chronic leg ulcers.
Main Methods:
- Case series reporting on three patients with chronic leg ulcers and venous insufficiency.
- Analysis of plasma for high levels of coagulation factor VIII (FVIII:C) activity and other thrombophilic factors.
Main Results:
- Three patients with chronic leg ulcers demonstrated high FVIII:C activity and associated thrombophilic factors.
- This suggests a potential link between specific thrombophilic states and venous disease presentation in younger individuals.
Conclusions:
- Consideration of thrombophilia workup, particularly for factor VIII deficiency, is crucial in young patients with venous disease, recurrent leg ulcers, or livedoid vasculopathy.
- Further large-scale studies are needed to establish definitive indications for thrombophilia screening in these patient groups.
Abstract:
Chronic venous disease affects millions of people around the world. Venous valvular incompetencies and venous reflux, often a result of outflow obstruction are important contributors to venous disease. The prevalence of thrombophilia is increased in patients with chronic venous insufficiency (CVI). The recognition of underlying thrombophilia particularly in young patients opens new avenues in the management and prevention plan. We emphasize on the consideration of workup for coagulopathy, especially factor VIII deficiency in young patients with venous disease. We report 3 patients with chronic leg ulcers and high levels of FVIII:C activity in plasma and other associated thrombophilic factors. We highlight the need to get a workup done for thrombophilia in young patients with recurrent and chronic leg ulcers related to venous insufficiency or livedoid vasculopathy. Further studies with larger sample sizes are required to define the definite indications for the thrombophilia workups.

The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
