Management of lower limb ischaemia associated with the use of intra-aortic balloon pumps during cardiac surgery.

ABSTRACT

OBJECTIVE: To audit the lower limb vascular complications associated with the use of an intraaortic balloon pump (IABP) on a cardiothoracic unit over a 12 month period. DESIGN: Retrospective analysis. SETTING: Regional university cardiothoracic unit. PATIENTS Fifty four IABPs inserted into 51 patients. RESULTS: Seventeen patients (33%) died from cardiogenic shock in the immediate postoperative period. Of the remaining 34 patients (37 IABPs), lower limb vascular complications occurred in nine patients (26%) who underwent 11 IABP insertions (30%). Vascular complications included groin haematomas (n = 2 insertions), compartment syndrome (n = 2 insertions), femoral artery trauma (n = 7 insertions). CONCLUSIONS: Prompt management by peripheral vascular surgeons resulted in limb salvage in 10 legs and only one death from a pulmonary embolus.
