A Comparative Analysis between Ultrasound-Guided and Conventional Distal Transradial Access for Coronary Angiography and Intervention

Figure 2

(a) A puncture with a 20 G needle under the long-axis ultrasound guidance. (b) The way of using the patient’s hand that has a wineglass makes us puncture under ultrasound guidance easily. (c) Long-axis ultrasound shows the distal radial artery. (d) The Doppler-ultrasound shows the blood flow in the radial artery. (e) Ultrasound shows the puncture with a 20 G needle.
