What this trial studies

This study aims to evaluate the effectiveness of Rivaroxaban in treating radial artery occlusion (RAO) following cardiac catheterization procedures, including angiography and percutaneous coronary intervention (PCI). It is a prospective, single-center, randomized controlled trial where patients with RAO will be divided into two groups: one receiving Rivaroxaban and the other receiving no anticoagulation. The primary goal is to assess the patency rates of the radial artery at four weeks post-procedure, while secondary objectives include comparing complications at the access site and systemic complications. RAO will be diagnosed using radial artery ultrasound within 24 hours after the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults undergoing coronary catheterization through the transradial access who have confirmed radial artery occlusion.

Not a fit: Patients under 18 years old or those with contraindications to Rivaroxaban will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve the recovery of the radial artery function and reduce complications after cardiac catheterization.

How similar studies have performed: Previous studies have explored treatments for RAO, but this approach using Rivaroxaban is relatively novel.
