The correlation between Caprini score and the risk of venous thromboembolism after varicose vein surgery.

Background: The study aims to identify the incidence of symptomatic and asymptomatic venous thromboembolism (VTE) after minimally invasive varicose vein surgery and to assess the predictability of the Caprini risk score (CRS).

Methods: CAPrini Score In Venous Surgery (NCT03041805) is a registry-based prospective study that enrolls patients undergoing minimally invasive open (high ligation, stripping, miniphlebectomy) and endovascular (thermal and non-thermal ablation) surgery on varicose veins. The main inclusion criteria are CRS assessment before intervention and a duplex ultrasound scan performance within 2-4 weeks after surgery.
