Transradial angiography was first reported in 1989.[1] Since then, this approach and other related interventions have been widely accepted as safe and cost-effective alternatives to the traditional transfemoral approach.[2–4][1] Compared with the femoral artery, the anatomic structure of the radial artery (RA) plays a key role in the occurrence of complications and failure of transradial percutaneous coronary intervention (TR-PCI).[5] The RA contains more smooth muscles than other vessels, and its vascular wall expresses primarily α1 adrenergic receptors with fewer β2 adrenergic receptors; accordingly, the RA is extremely sensitive to catecholamines and is prone to spasms if directly or repeatedly stimulated by a guidewire.[5] Transradial anatomic variations (TRAVs), such as variations of radial, brachial, and subclavian arteries, and the brachiocephalic trunk/ascending aort...
