Total aortic occlusion caused by sustained balloon inflation: a previously unreported complication of intraaortic balloon counterpulsation.

A case of acute lower-body ischemia 2 days following intraaortic balloon pump insertion is reported. Fluoroscopy revealed persistent balloon inflation throughout the cardiac cycle with distal aortic occlusion. Attempts to manually deflate the balloon were unsuccessful until a guidewire was advanced through the gas-exchange lumen into the body of the balloon. The balloon catheter was removed without clinical sequelae other than transient oliguria and an asymptomatic increase in creatinine phosphokinase (CPK). This is a previously unreported complication of intraaortic balloon counterpulsation.

A new technique for sheathless percutaneous intraaortic balloon catheter insertion.

Intraaortic balloon counterpulsation is helpful for controlling myocardial ischemia and providing hemodynamic support, but its applicability is limited by lower extremity ischemic complications in a significant percentage of patients. We developed a new sheathless technique for percutaneous intraaortic balloon catheter insertion which reduces the effective catheter diameter. A pilot study using this new technique resulted in a 10% rate of limb ischemia, without compromise of balloon function. We conclude that this technique may be useful in reducing the incidence of limb ischemia associated with intraaortic balloon counterpulsation.
