The Epiaortic Ultrasound Diagnosis of Iatrogenic Subadventitial Hematoma.

Iatrogenic aortic injury is a rare but potentially lethal complication of cardiac surgery. While sometimes resulting in aortic dissection or intramural hematoma, injury more frequently results in subadventitial hematoma, a more benign pathology. Here, we describe a case where intraoperative transesophageal echocardiography (TEE) identified such a hematoma but was unable to rule out dissection. Epiaortic ultrasound was subsequently performed, which definitively demonstrated the absence of a dissection flap or extraluminal flow. Per our review, this is the first report documenting the successful use of epiaortic imaging to identify subadventitial hematoma in the setting of inconclusive TEE findings.
