[Coronary artery spasm during cholecystectomy with pneumoperitoneum--a case report].

A 59-year-old man without a history of ischemic heart disease underwent elective laparoscopic cholecystectomy under general anesthesia with epidural anesthesia. About 15 min after pneumoperitoneum had been achieved, the patient developed ST elevation and hypotension. Vagal stimulation resulting from stretching peritoneum, the procedure and epidural anesthesia are thought to have induced vasospasm. The ST segment became normal after interruption of CO2 insufflation. A postoperative coronary artery angiogram showed normal coronary arteries, but diffuse coronary artery spasm was seen after intracoronary injection of acetylcholine. The patient was discharged on nitrates. Patients with gall bladder stones sometimes have coronary risk factors of obesity, hyperlipidemia and hyperglycemia. Careful attention should also be given to patients who do not have a history of coronary disease.
