A prospective randomized study comparing surgical and percutaneous removal of intraaortic balloon pump

This prospective randomized study of 50 patients compares the prevalence of complications between surgical and percutaneous methods of removal of intraaortic balloons. All patients who had percutaneous placement of a 9.5F intraaortic balloon during a 6-month period were eligible for the study. Patients were excluded if the intraaortic balloon was placed surgically, if a coagulopathy was present, or if acute leg ischemia developed at any time after insertion. After informed consent, 25 patients were randomized to each method of removal. Two complications occurred in the surgical group, including a wound infection and a lymph fistula. In one patient in the percutaneous group, a false aneurysm of the femoral artery developed. There was no significant difference between the mean of 59 minutes for percutaneous removal and 47 minutes for operative removal of the balloon (p = 0.74). The percutaneous method is therefore more cost-effective, because it does not require the use of operating room personnel or equipment necessary for surgical removal. The results of this study indicate that the majority of percutaneously placed intraaortic balloons may be safely removed percutaneously. Surgical removal of 9.5F intraaortic balloons is recommended for patients with bleeding diatheses, hemorrhagic or ischemic complications, or for those in whom the intraaortic balloon was inserted with a surgical procedure.
