Validation of Caprini Score for Patients Undergoing Varicose Vein Surgery
Official title: A Prospective Cohort Register Study for Validation of Caprini Score in Patients Undergoing Varicose Vein Surgery
Run by Pirogov Russian National Research Medical University · NCT03041805 · Data updated 2026-11-12
This study is testing if the Caprini score can help identify adults having varicose vein surgery who are at higher risk for blood clots after their procedure.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 18 years undergoing any type of varicose vein surgery.
✕Probably not a fit
Patients who are lost to follow-up during the 4-week post-operative period may not benefit from this study.

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.
