Which of the following is a complication associated with an Intra Aortic Balloon Pump?

• A. Aortic wall dissection, rupture, local vascular injury
• B. Hyperkalemia
• C. Pulmonary fibrosis
• D. Renal cell carcinoma

Answer: (A)

Complications from an intra-aortic balloon pump come mainly from the catheter and balloon interacting with the arterial and aortic walls. The device is threaded into the femoral (or other large) artery and the balloon sits in the thoracic aorta, inflating and deflating with the cardiac cycle. This mechanical interaction can injure the vessel lining, leading to aortic wall dissection or even rupture, and it can cause local vascular injury at the access site or along the arterial path. Hematoma, pseudoaneurysm, and limb ischemia are related vascular problems that can arise from this instrumentation.

Hyperkalemia, pulmonary fibrosis, and renal cell carcinoma are not direct, typical complications of IABP therapy. Hyperkalemia might relate to renal issues or other systemic problems, but it is not a classic IABP complication. The others are unrelated chronic conditions rather than procedure-related vascular complications.
