The long-term effects of venous thrombosis, known collectively as PTS, include persistent swelling, pain, cramps, and numbness in the leg. These symptoms result from impaired return of blood through the veins of the lower leg to the heart. PTS is believed to occur as a result of direct damage to the valves and walls of the vein. There may be specific factors that make certain individuals more prone to PTS. Individuals who are obese, have a genetic predisposition to blood clotting disorders, or have high levels of inflammation biomarkers may have an increased risk of developing venous diseases. The purpose of this study is to investigate the possible link between these factors and the occurrence of chronic venous disease and PTS. The study's findings will be useful in developing new prevention and treatment strategies.
