AbstractIn this prospective study we sought to establish the incidence and nature of lower limb ischemia in patients undergoing treatment with intraaortic balloon pump (IABP) counterpulsation and to determine risk factors for its development. The sample was composed of all 258 balloon catheter insertions or attempted insertions for IABP therapy in 249 patients during a 16-month period. Assessment of the lower limbs, hemodynamic status, and pertinent medications were recorded daily throughout the patient's hospitalization. Lower limb ischemia was present in 47%, with 14% having major ischemic complications. Multivariate logistic regression, which was based on variables found to be significant in univariate analysis, revealed that preexisting peripheral vascular disease, female sex, and diabetes mellitus were related to the development of the whole range of lower limb ischemic problems. Diabetes mellitus, cardiogenic shock, and a history of smoking were associated with major ischemia. Evaluation of risks and benefits before treatment with IABP counterpulsation and careful lower limb assessment before, during, and after counterpulsation may help reduce the complications associated with this lifesaving device.
