What this trial studies

This observational study aims to validate the Caprini score in patients undergoing various types of varicose vein surgeries, particularly focusing on endovascular procedures such as endovenous laser treatment, radiofrequency ablation, and ultrasound-guided foam sclerotherapy. It will enroll adult patients and monitor them for venous thromboembolic complications within 2-4 weeks post-surgery using duplex ultrasound. The study seeks to identify patients at elevated risk for postoperative venous thromboembolism (VTE) who may benefit from prophylactic anticoagulation.

Why it matters

Potential benefit: If successful, this study could enhance the identification of patients at risk for VTE, leading to improved prophylactic treatment strategies.

How similar studies have gone: Other studies have shown success in using risk assessment scores like the Caprini score for predicting VTE, indicating that this approach is supported by prior research.
