Delayed extensive right brachial and radial artery thrombosis: A rare complication of transradial cardiac catheterization

Cardiac catheterization via transradial approach (TRA) has increased in prevalence surpassing femoral artery approach. Radial artery occlusion (RAO), a well-known complication post cardiac catheterization, typically occurs immediately after cardiac catheterization and is usually asymptomatic not requiring any intervention. We encounter a unique case of extensive brachial and radial artery occlusion more than two months after cardiac catheterization, demonstrating the importance of a thorough history, and the need for increased awareness regarding the possibility of delayed presentation of cardiac catheterization complications.
