Emergency department point-of-care ultrasound diagnosis of active bleeding into the intraluminal thrombus of an abdominal aortic aneurysm.

Rupture of an abdominal aortic aneurysm (AAA) is an immediately life-threatening phenomenon with substantial mortality. Although most AAAs are asymptomatic, an impending AAA rupture can be heralded by nonspecific symptoms and imaging findings on CT and point-of-care ultrasound (POCUS). In this report, we present a case of an 81-year-old male with an atypical presentation of an AAA with novel sonographic findings of imminent rupture on POCUS with Doppler that prompted successful emergent intervention. In the emergency department, imaging findings on aortic POCUS and CT imaging with angiography can facilitate assessment for impending aortic rupture, which can expedite appropriate disposition and potentially life-saving intervention.
