Absence of vasospasm in radial artery CABG on high-dose norepinephrine.
One of the concerns in using radial artery as coronary artery bypass grafts centers around its unusual propensity for vasospasm when experimentally exposed to norepinephrine. This case report demonstrates an absence of vasospasm in a radial artery graft on high dose norepinephrine and may provide reassurance when alpha-agonists are required in this setting.
