[A case of bilateral internal thoracic artery bypass grafting in sudden death survivor with multivessel coronary spasms].
We report a 58-year-old male with a history of cardiac arrest due to coronary artery spasm, preoperative coronary arteriograms showed multivessel coronary spasm after the administration of ergonovine maleate associated with triple vessel fixed stenotic lesions. Under the use of cold diltiazem potassium-blood cardioplegic solution to prevent perioperative coronary spasm, coronary artery bypass grafting was performed. The right internal thoracic artery (ITA) was anastomosed to the left anterior descending artery and the left ITA to the circumflex artery. A saphenous vein graft was anastomosed to the right coronary artery. The postoperative course was uneventful. In postoperative coronary angiography with ergonovine stimulation, neither ITA grafts showed spastic changes, and the coronary artery distal to the anastomotic sites were well perfused through the ITA grafts. The patient has been free of angina without administration of calcium antagonist and been doing well for 2 years and 5 months since the operation.
