FIELD: medicine.

SUBSTANCE: for prevention and relief of spasm of the internal mammary artery or the radial artery during preparation for use as a bypass during coronary bypass, arterial vessel is isolated, and its distal end is crossed. The proposed solution is intriduced into the vessel lumen via the soft catheter and the vessel is clipped so that the solution remained in the lumen of the taken vessel, and the other end of artery is not clipped. The proposed solution comprises 0.1% solution of nitroglycerin - 20.0 ml; 0.25% solution of verapamil hydrochloride - 4.0 ml; 4% solution of sodium hydrogencarbonate - 10.0 ml; Heparin - 500 units; saline - up to 200.0 ml. Then the arterial vessel is treated from the outside with the same solution along the entire length by the G21 needle syringe so that it is foamed on the artery surface. After syringe processing, the artery is wrapped in cloth soaked liberally in the proposed solution and it is left in the bed until it is required to form a bypass.

EFFECT: method provides effective prevention and removal of spasm of arterial bypasses in the absence of intima damage and vascular occlusion.
