Consistence of the radial artery as a conduit used in aortocoronary bypass surgery, a possibility of preventing shunt spasm

Abstract

AIM: To develop a new procedure to evaluate the functional consistence of the radial artery (RA) as a conduit used in aortocoronary bypass surgery (ACBS), to verify the prognostic value of the changed diameter of RA, and to prevent its spasm. /MATERIAL AND METHODS: The study enrolled 34 patients aged 59.4±8.6 years with coronary artery stenoses, who underwent ACBS using a RA conduit. While preparing them for surgery, endothelium-dependent vasodilation (EDVD) of RA, i.e. the magnitude of a change in its diameter (ΔD) was assessed; RA tone and nitric oxide (NO) concentrations were estimated during surgery; RA EDVD was re-estimated in 12 lercanidipine-treated patients with ΔD
