Abstract

Recent advances in the operative management of aortic aneurysms have resulted in a decreased rate of morbidity and mortality. In 1972, we hypothesized that a further reduction in operative mortality might be obtained with controlled perioperative fluid management based on data provided by the thermistor-tipped pulmonary artery balloon catheter. From 1972 to 1979 a flow directed pulmonary artery catheter was inserted in each of 110 consecutive patients prior to elective or urgent repair of nonruptured infrarenal aortic aneurysms. The slope of the left ventricular performance curve was determined preoperatively by incremental infusions of salt-poor albumin and Ringer's lactate solution. With each increase in the pulmonary arterial wedge pressure (PAWP), the cardiac index (CI) was measured. The PAWP was then maintained intra- and postoperatively at levels providing optimal left ventricular performance for the individual patient. There were no 30-day operative deaths among the patients in this series and only one in-hospital mortality (0.9%), four months following surgery. The five-year cumulative survival rate for patients in the present series was 84%, a rate which does not differ significantly from that expected for a normal age-corrected population. Since the patient population was unselected and there were no substantial alterations in operative technique during the present period, these improved results support the hypothesis that operative mortality attending the elective or urgent repair of abdominal aortic aneurysm can be minimized by maintenance of optimal cardiac performance with careful attention to fluid therapy during the perioperative period.
