Radial versus femoral access for rescue percutaneous coronary intervention with adjuvant glycoprotein IIb/IIIa inhibitor use.

BACKGROUND: The transradial approach has not been evaluated for "rescue" percutaneous coronary intervention (PCI) with glycoprotein (GP) IIb/IIIa inhibitor following failed thrombolysis.

OBJECTIVES: To compare the safety and procedural outcomes of the transradial and transfemoral approaches to rescue PCI.

METHODS: Rescue PCI cases with adjuvant GP IIb/IIIa inhibitor performed at two centres were reviewed retrospectively, and the bleeding rates, equipment use and procedure times for the femoral and the radial approach were compared.

RESULTS: Radial access was attempted in 47 of 111 cases (42%) and crossover to femoral access was required in two cases (4%). Major bleeding occurred in three patients in the radial group (6%) and in 12 patients in the femoral group (19%; P=0.06). Radial access was associated with less access site-related major bleeding (0% versus 9%; P=0.04) and fewer transfusions (4% versus 19%; P=0.02). After excluding patients with intra-aortic balloon pump, this difference was no longer statistically significant (4% versus 8%; P=0.7). Fluoroscopy times and contrast use were similar, and the time to first balloon inflation was slightly longer with radial access (33 min versus 30 min; P=0.07).

CONCLUSIONS: In selected patients, the transradial approach for rescue PCI is safe and effective. The present findings warrant further study in a prospective, randomized trial.
