case_images: Barbeau test shows a D waveform recorded through the pulse oximeter. It demonstrates a loss of pulse tracing without recovery within 2 min (yellow line at the bottom).

case_images: Barbeau test showing a type D waveform (Figure 1), which is a contraindication to TRA. Both high risk of bleeding to FA and the contraindication to the TRA forced us to find another possible arterial access with less risk of complications.
case_images: The 4 F sheath placed in the distal radial artery at the site of the anatomical snuffbox.

case_images: After a 4-French sheath was inserted (Figure 2), another bolus of nitroglycerin (200 mug) and heparin (2000 IU) were administered intra-arterially on the basis of our institutional protocol.
case_images: (a) TR band placement at the site of the vascular access, (b) insufflation of air, (c) removal of the sheath and (d) final result in the absence of bleeding.

case_images: Hemostasis was obtained with the TR band injecting 7 cm of air, deflating 1 cm every 5 min on the basis of our protocol for RA (Figure 3).
