ClinConnect Summary

This clinical trial is studying the use of a medication called Rivaroxaban, combined with aspirin, to help prevent a serious condition known as venous thromboembolism (VTE) in patients who are having surgery to improve blood flow in their legs. VTE can happen when blood clots form in the veins and can lead to complications, especially in patients who have other health issues. The goal of the study is to see if using Rivaroxaban as a preventive measure is effective for patients undergoing these types of surgeries, which are often necessary for those with severe leg circulation problems.

To be eligible for this trial, participants should be adults of any age and gender who are scheduled for surgery to treat critical limb ischemia, a serious condition affecting blood flow to the legs. They will need to sign a consent form before participating. However, people who have had a recent clotting event or have certain health issues that prevent them from taking Rivaroxaban cannot participate. Those who join the study will be monitored closely and will need to return for a follow-up visit 30 days after their surgery to check on their recovery and the effectiveness of the treatment. This trial is currently looking for participants and aims to provide important information about the best ways to prevent blood clots after surgery.

• • 3. Sign the informed consent form (ICF) (Appendix 2).
• Exclusion Criteria:
• • 1. Experience a symptomatic VTE event during hospitalization, as they will require full anticoagulation rather than prophylactic anticoagulation.
