Vascular complications and clinical outcome after coronary angioplasty with platelet IIb/IIIa receptor blockade. Comparison of transradial vs transfemoral arterial access.

Abstract

Vascular complications associated with femoral artery access for interventional cardiological procedures may increase morbidity especially in patients receiving anticoagulants, aspirin, ticlopidine and platelet glycoprotein IIb/IIIa receptor inhibitors. The use of radial arterial access has the potential to reduce the incidence of access site bleeding complications. The purpose of this study was to compare outcomes after the radial and femoral approaches in patients treated with the platelet IIb/IIIa inhibitor, abciximab. One hundred and fifty consecutive patients treated by abciximab underwent angioplasty by the radial or femoral approach in 83 and 67 cases, respectively. Outcome variables were major cardiac events and major access site bleeding at 1-month follow-up. Freedom from major cardiac events at 1-month follow-up occurred in 78 (93.9%) and 63 (94.0%) patients in the radial and femoral groups, respectively (P=0.99). There were no major access site bleeding complications in the radial group, as opposed to five (7.4%) in the femoral group, P=0.04. Postprocedure length of stay, days (3.7+/-6.0 radial vs 3.7+/-2.6 femoral, P=0.96) as well as total hospital length of stay (5.0+/-4.3 radial vs 4.9+/-3.0 femoral, P=0.72) were similar in both groups. Coronary angioplasty in patients treated by abciximab using the transradial approach is efficacious with fewer major access site complications than with the transfemoral approach.
