[PTCA and coronary artery bypass operation prior to subsequent surgery of gastric cancer in patients with coronary artery disease].

Two patients with coronary artery disease required operation for gastric cancer. In one patient with single vessel disease, 37 days later after successful PTCA, gastric resection for early gastric cancer was performed without any cardiac complication. The other patient with severe three vessel disease initially underwent coronary artery bypass operation, and 13 days later gastric resection for advanced cancer was performed. This patient developed supraventricular arrhythmia as a sole complication which was easily controlled by medical treatment. In both cases, fentanyl was used as an anesthetic agent and nitroglycerin was continuously administered intravenously during the perioperative period. ECG, central venous pressure, and direct arterial pressure were also carefully monitored. We feel that noncardiac operation such as gastric resection can be performed without major cardiac complications even shortly after coronary artery bypass operation.
