title: [Transradial coronary procedures in patients with high origin of the radial artery (axillary origin): two case reports and anatomical and technical considerations].
abstract: Background. Anatomical abnormalities (caliber and course) of radial artery are a potential limiting factor for diagnostic and interventional coronary procedures performed through the transradial approach. In these circumstances, prompt and careful angiographic assessment of the radial anatomy is crucial after sheath insertion in order to minimize the risk of vascular complications or access failure. Two case reports of a high origin of the radial artery (from the axillary artery) are described. After brief review of the anatomical classification of this abnormality, the different catheterization techniques to achieve procedural success and avoid switching to an alternative vascular access are discussed.
