BACKGROUND: Radial access is the default approach in interventional cardiology. The Axiostat® surgical hemostatic dressing, using chitosan as its active component, has demonstrated potential in accelerating blood clotting. This study aims to assess the efficacy and the safety of the Axiostat® dressing in achieving hemostasis in patients undergoing transradial coronary angioplasty (TRCA).
METHODS: This prospective, single-center observational study, conducted in 2022, enrolled consecutive patients undergoing TRCA, with a target of 150 participants. The primary outcome was the success rate of radial artery hemostasis at 120 min, without bleeding necessitating immediate re-compression. The secondary outcome included Axiostat® performance at 24 h and 30 days Postprocedure.
RESULTS: The study was terminated prematurely for ethical and patient safety reasons, after inclusion of 41 consecutive TRCA patients due to an unexpectedly high radial artery thrombosis rate (19.5%, n = 8/41) observed 24 h Postprocedure. The success rate of radial hemostasis with the Axiostat® dressing was 78.0%. Procedural details and patient characteristics were comparable between successful Axiostat® removal and device failure cases.
CONCLUSION: The use of the Axiostat® dressing to achieve hemostasis after TRCA is effective but is associated with an unexpectedly high incidence of radial thrombosis. Our results should encourage caution in the future evaluation and use of this device for radial artery compression following TRCA.
