Native Coronary Artery and Grafted Artery Spasm Just after Coronary Artery Bypass Grafting: A Case Report

Abstract: Native coronary artery spasm after coronary artery bypass grafting (CABG) is scarce. It frequently causes disastrous circulatory collapse. We report a 72-yr-old male, who experienced native coronary artery spasm and grafted artery spasm following CABG, which was successfully treated with coronary angiography and intracoronary injection of nitroglycerine.

“…There are approximately 1.6 million coronary artery bypass procedures performed annually in the United States, 18 and acute coronary vasospasm occurs in 1–8% of all patients undergoing coronary artery bypass grafting. 19 Treatment of coronary vasospasm includes immediate, invasive intracoronary administration of vasodilators such as nitroglycerin or verapamil. 20 The approach described here would be less invasive and would be applied prophylactically (intraoperatively) prior to grafting.…”

“…Clinicians should therefore consider the possibility of vasospasm in patients who had alterations in ECG rhythm and hemodynamic profile after open heart surgery [12]. The possible etiologic factors of coronary vasospasm include elevated catecholamine levels, the use of catecholamines such as dopamine during surgery, discontinuation of preoperative use of β-blockers or calcium channel blockers during surgery, intraoperative occurrence of vascular injury, alkalosis due to hyperventilation, the release of platelet-derived vasospastic factors (e.g., thromboxane A2), autonomic nervous stimulation, hypomagnesemia, hypothermia, and irritation from chest tube [24].…”
