CTICasesAortic Intramural Hematoma from Intra-Aortic Balloon Pump Injury
Imaging findings
CT demonstrates increased attenuation surrounding the aortic arch and descending thoracic aorta, consistent with an intramural hematoma (IMH). A focal intimal rent or defect is visible in the aortic wall, representing the site of mechanical injury from the intra-aortic balloon pump (IABP).
Key takeaways
Placement or presence of an intra-aortic balloon pump can cause mechanical intimal injury and subsequent aortic intramural hematoma or dissection. While rare, clinicians should consider this complication when patients experience severe chest pain during IABP insertion.
