Electrical calf muscle stimulation in patients with post-thrombotic syndrome and residual venous obstruction after anticoagulation therapy
Abstract
The aim of this study was to assess the impact of electrical calf muscle stimulation (EMS) on clinical and ultrasound outcomes in patients with post-thrombotic syndrome (PTS) and residual venous obstruction (RVO). This was a prospective, comparative, non-randomized clinical trial involving patients who had completed a standard 6-month course of anticoagulation therapy for a first episode of unprovoked femoro-popliteal DVT and had signs of RVO in the affected veins and PTS as shown by a Villalta Score of >5. A blinded outcome assessor performed the ultrasound evaluations. A total of 60 patients in the age range from 40 to 86 years (mean 58.5±11.4) consisting of 38 men and 22 women were enrolled. They were divided into two groups of 30 participants each. Both groups (experimental and control) were treated by active walking, below-knee graduated compression stockings, and micronized purified flavonoid fraction. In the experimental group, EMS with «Veinoplus VI» device (three applications for 30 min every day) was also used. The patients were followed for 12 months with monthly DUS to reveal recurrent DVT and changes in RVO. The clinical criteria for treatment efficacy included changes in Villalta, VCSS and CIVIQ-20 scores. Recurre...Continue Reading

Blood Clotting Disorders
Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
