Incidence and outcome of radial artery occlusion following transradial artery coronary angioplasty.
Coronary angioplasty with 6F guiding catheters via the radial artery is associated with a minimal risk for major entry site-related complications. Although the incidence of radial artery occlusion (RAO) in the literature is approximately 30% after prolonged cannulations, little is known about the incidence and its clinical consequences of RAO following transradial percutaneous coronary angioplasty. In a prospective study, 563 patients with a normal Allen test were evaluated on patency and function of the radial artery after transradial angioplasty, by physical and ultrasound examination at discharge, and at 1 month follow-up. At discharge, 30 patients (5.3%) had clinical evidence of RAO. At follow-up, persistent RAO was found in 16 patients (2.8%). In this study we found a low incidence of RAO after transradial percutaneous coronary angioplasty. None of the patients with temporary or persistent RAO had any major clinical symptoms. Therefore, the occurrence of RAO can be considered a minor complication in patients with a previously good double blood supply to the hand.
