In Vivo and In Vitro Effects of Stellate Ganglion Blockade on Radial and Internal Mammary Arteries

Conclusion: The present results show that SGB not only increases distal RA and IMA diameters but is also associated with in vitro differences, the mechanism of which remains to be elucidated. Therefore, SGB might be considered as an alternative to topical and systemic vasodilators for reducing vasospasm in patients undergoing CABG.
