Restoration of muscle-pump function in chronic venous insufficiency

Area of Science:

• Vascular Medicine
• Phlebology
• Biomedical Engineering

Background:

• Chronic venous insufficiency (CVI) affects a significant portion of the population.
• Impaired venous return and muscle pump function characterize CVI.
• Objective assessment of treatment efficacy in CVI is crucial.

Purpose of the Study:

• To evaluate the effectiveness of conservative treatment for chronic venous insufficiency.
• To assess the impact of elastic support, exercise, and sclerotherapy on venous pressure dynamics.
• To determine the utility of direct venous pressure profiling in monitoring CVI treatment outcomes.

Main Methods:

• Direct venous pressure profiles were recorded in 15 CVI patients before and after treatment.
• Treatment involved conservative measures: elastic support, walking exercises, and sclerotherapy for incompetent perforators.
• Venous pressure drop during tiptoeing and return time to resting pressure were measured.

Main Results:

• The average venous pressure drop during tiptoeing increased significantly from 31.6% to 50.9% (P < 0.01).
• The time for venous pressure to return to resting levels increased from 6 seconds to 12.9 seconds (P = 0.01).
• These hemodynamic changes correlated with clinical and subjective improvements in patients.

Conclusions:

• Conservative treatment, including sclerotherapy for incompetent perforators, effectively improves calf muscle pump function in CVI.
• Direct venous pressure profiling is a valuable tool for assessing treatment efficacy in venous disorders.
• This combined therapeutic approach is recommended for managing chronic venous insufficiency.
