high-risk coronary angioplasty using percutaneous cardiopulmonary bypass support.balloon angioplasty has a high success rate but results in abrupt closure of the vessel in 2% to 6% of patients. this can lead to haemodynamic collapse and death, particularly if the patient has poor left ventricular function. in the event of abrupt closure of the coronary vessels, such patients may not survive long enough to undergo emergency bypass surgery. the prophylactic use of cardiopulmonary bypass to support patients at high-risk for angioplasty has been reported recently. we describe ou ...19981302578
the evolution of asymptomatic monoclonal gammopathies. a follow-up of 20 cases over periods of 3-14 years.twenty cases of "asymptomatic" monoclonal gammopathies were detected by routine electrophoresis in patient's sera or in blood donors and were followed over 3-14 years. four cases have shown a malignant evolution-two evolved toward waldenström's macroglobulinemia after 3 years and two could be classified as myeloma 3 and 7 years, respectively, after detection of the monoclonal protein. the remaining cases were still "asymptomatic" 4 years later (7 cases), 7-9 years later (8 cases) and 14 years la ...1998107729
