About this study

Coronary angiography and angioplasty are commonly performed through the radial artery at the wrist as this approach is associated with fewer bleeding complications and faster recovery. In some patients, the radial artery becomes occluded after prior procedures, requiring selection of an alternative access site for future coronary interventions. The ulnar artery is a potential alternative wrist access. However, limited data are available on the safety of using the ulnar artery in the same arm as an occluded radial artery and on the possible effects on hand strength, sensation, and daily hand function. The goal of this observational study is to evaluate the safety of transulnar access and its effect on hand function in adults with ipsilateral radial artery occlusion undergoing coronary angiography or angioplasty. The main questions addressed by the study are: * How often do serious access-related vascular or nerve complications occur? * Does hand strength, sensation, or functional use of the hand change during follow-up? * Does the ulnar artery remain patent after the procedure? The choice of vascular access site is made by the treating physician based on clinical judgment. Participants who undergo transulnar access will undergo follow-up assessments, including ultrasound evaluation of arm arteries, standardized hand function testing, and short questionnaires assessing upper-limb function. The findings of this study are expected to inform access-site selection, improve pat…
