Distal radial artery access for the treatment of complications after ulnar artery catheterization

Objective: to study the effectiveness of the distal radial artery access in the treatment of complications after ulnar artery catheterization. Material and methods. We analyze the outcomes of 1558 catheterizations of the ulnar arteries. Less than 1% of local hemorrhagic complications and 1.5% of post-catheterization occlusions of the ulnar artery were revealed after ulnar artery catheterization, Results. One half of the patients with hemorrhagic complications after ulnar artery catheterization underwent conservative treatment (mechanical compression of the site of complication), the rest of patients underwent surgical treatment. Positive effect was achieved in all patients who underwent endovascular treatment for post-catheterization hemorrhagic complications. In 50% of cases, recanalization of post-catheterization ulnar artery occlusion via the distal radial access was effective. In 1 patient after recanalization of post-catheterization ulnar artery occlusion using the distal radial artery access, the occlusion of radial artery in wrist segment occurred, with preserved blood flow in radial artery of the forearm. Conclusion. Distal radial artery access for correction of post-catheterization complications in ulnar artery is a feasible and safe method.
