ARTERY OCCLUSION
Transradial coronary angiography was performed in a very standardized fashion. Only hydrophilic coated introducer sheaths from 5 to 7 French and 10 cm length were used (Glidesheath SlenderOn the day following angiography, patients underwent a physical examination of the arm and the vascular access site. A duplex ultrasonography was performed in all patients using a portable device (Vscan Extend, Ultrasound GE Healthcare GmbH, Solingen, Germany). In case of absent flow of the radial artery, patients were sent for a further, more thorough ultrasound study to our department of angiology. Confirmation of radial artery occlusion was defined as an absence of antegrade flow determined by duplex ultrasonography.
