Unilateral Headache Status after Intra-Aortic Balloon Pump Placement

Area of Science:

• Cardiology
• Neurology
• Vascular Surgery

Background:

• Intra-aortic balloon pump (IABP) counterpulsation is a critical treatment for advanced coronary artery disease and heart failure.
• Axillary artery access for IABP offers ambulation benefits over traditional femoral access, particularly for transplant candidates.
• IABP complications typically involve vascular issues or hematologic effects.

Observation:

• A patient awaiting heart transplant with ischemic cardiomyopathy required IABP via the left axillary artery due to severe symptoms.
• Following IABP placement, the patient developed persistent, unilateral headaches unresponsive to conventional pain management.
• The patient's headache resolved completely upon removal of the intra-aortic balloon pump.

Findings:

• The case suggests a potential association between axillary artery IABP and the onset of severe unilateral headaches.
• The headache's resolution after IABP removal strongly indicates the device as the causative factor.
• This adverse event highlights a previously undocumented complication of axillary IABP therapy.

Implications:

• Clinicians should consider IABP-induced headache in patients presenting with new-onset unilateral headaches after axillary artery cannulation.
• Further research is warranted to elucidate the mechanism linking axillary IABP to cerebral vasodilation and headaches.
• This finding may influence patient selection and monitoring protocols for axillary IABP placement.
