Intraoperative chlorpromazine treatment for prevention of radial artery spasm in aortocoronary bypass grafting

Abstract

A detailed description of intraoperative prevention of radial artery graft spasm using a solution of the calmodulin inhibitor chlorpromazine is presented. This method is used in direct myocardial revascularization and can reliably prevent perioperative spasm of radial artery grafts, as confirmed by intraoperative flow measurement, bypass angiography in the postoperative period, and in vitro experimental data.
