Distal transradial access to prevent proximal radial artery occlusion: what is really known?

Transradial access (TRA) offers important advantages over transfemoral approachs, including early patient ambulation, improved comfort, less vascular complications, lower health care costs, and reduced adverse cardiovascular events, mortality. Nevertheless, complications of TRA still exist, radial artery occlusion (RAO) occurred in up to 30% cases, a prospective ultrasound study. Due dual blood supply the hand, RAO is usually asymptomatic unnoticeable, although sometimes it may be associated with distal ischemia, paresthesia, pain at [...]
