Evaluation of Chitosan-Based Axiostat as Hemostatic Dressing for Endovascular Procedures in Patients with Leriche Syndrome on Anticoagulant Therapy

Abstract

Background/Objectives: The safe completion of a non-invasive procedure is crucial to the success of an endovascular approach. Chitosan, a natural polysaccharide derived from chitin, is an ideal material for the study and application of medical devices in post-operative wound management. Methods: The present work is based on a retrospective study conducted on a sample of patients treated with Axiostat (a sterile, single-use, non-absorbable dressing), composed of 100% chitosan and designed to instantly stop bleeding through a mucus adhesion mechanism for the treatment of conditions such as Leriche's syndrome. The objective was to evaluate the efficacy and safety of the hemostatic Axiostat dressing in patients undergoing anticoagulant and/or antiplatelet therapy in whom endovascular procedures using the axillary artery as an access site are performed to treat Leriche syndrome. Results: The obtained results showed that Axiostat is safe and effective in promoting hemostasis at the axillary vascular access site even when prolonged hemostasis was required in patients on antiplatelet and anticoagulant therapy. The mean time to hemostasis was 5.75 min in all types of patients considered.
