Safety and Hand Function After Transulnar Artery Access in Adults with Radial Artery Occlusion Undergoing Coronary Angiography or Angioplasty

What this Trial Is About

Researchers are evaluating the safety and effects on hand function of using the ulnar artery for coronary angiography or angioplasty in adults who have a blocked radial artery on the same arm. This observational study focuses on patients with radial artery occlusion requiring an alternative access site and aims to understand complications, changes in hand strength and sensation, and artery patency over time. Participants undergo coronary procedures with transulnar arterial access selected by their doctor. The study does not assign treatment but observes patients who receive transulnar access, following them with ultrasound exams of arm arteries, objective tests of hand strength and sensation, and questionnaires about hand function. Assessments are done before, shortly after, and at several points up to six months post-procedure. During the study, participants will have ultrasound imaging, quantitative neuromuscular testing, sensory evaluations, and surveys to monitor recovery and detect any complications. The main measure is the rate of serious vascular or nerve complications within 30 days. Secondary measures include procedure details, artery patency at various times, changes in hand strength and sensation, patient-reported hand function, and late complications up to six months. The findings aim to support safer care and guide access site decisions for patients with radial artery occlusion.
