Comparative Study[Vaso-reactive properties of radial and internal mammary arteries: application to coronary bypass surgery].
Satisfactory results were obtained with the radial artery used as a conduit for coronary artery bypass. However, spasm of this conduit was observed. Human radial and internal mammary artery ring segments were studied in organ chambers. ⋯ The radial artery presents stronger contractions than the internal mammary artery. The two vessels have equal sensitivity to the vasoconstrictors used. These data emphasize the hyperreactivity of the radial artery and the need for prevention of vasospasm when this vessel is used as a conduit for coronary artery bypass.
