    Abstract:
    Intraaortic balloon counterpulsation is an established and efficient therapy. Limb ischemia is the most common complication. The impact of treatment duration on balloon-related complications was analyzed retrospectively in 135 patients who underwent balloon counterpulsation between 1998 and 2004. Thirty high-risk coronary patients required preoperative intraaortic balloon therapy, 41 were in preoperative cardiogenic shock, and 64 needed support for difficulties in weaning from cardiopulmonary bypass. No balloon-related mortality occurred. The overall balloon-related complication rate was 20/135 (14.8%); 18 had limb ischemia, of whom 6 (4.4%) required vascular interventions. Intraaortic balloon treatment time was significantly longer in patients who developed limb ischemia (99.8 +/- 54.1 h) compared to those who did not (34.4 +/- 30.4 h). Preoperative therapy had short treatment times and few complications. Intraaortic balloon pumping provides effective circulatory support with a low complication rate. A clear relationship was established between duration of treatment and balloon-related complications. Independent risk factors for balloon-related complications were long treatment time, acute myocardial infarction, age over 65 years, and ejection fraction less than 0.30.
