[Coronary artery bypass grafting in an octogenarian with chronic myelomonocytic leukemia].

ABSTRACT

Chronic myelomonocytic leukemia is a disease of the elderly. It tends to have a variable clinical course, as the patient's state is immunologically dysunctional. There has been reluctance to perform open cardiac procedures because of concern about early postoperative sepsis leading to death. A 84-year-old man was admitted for the management of effort angina. PTCA was performed twice. He had left nephrectomy for Grawitz tumor nine years ago and additionally, he had been diagnosed as having chronic myelomonocytic leukemia since the next year. Preoperative laboratory assessment revealed that the total white blood cell counts were 2500 with 25 per-cent of granulocytes, a hematocrit of 31.1%, and platelet counts were 10.0 x 10(4). At the night of the treatment of his granulocytopenia with injection of granulocyte stimulating factor, he complained of continuous anterior chest pain with ST depression on ECG. Emergency single CABG was performed using a saphenous vein graft under the diagnosis of impending myocardial infarction. Postoperative course was uneventful. This is the first case report of CABG in octogenarian with chronic myelomonocytic leukemia in the world.
