Aortic intimal separation resulting from manual cardiopulmonary resuscitation-completing the spectrum of blunt thoracic aortic injury complicating CPR.

Abstract：

:Blunt thoracic aortic injury (BTAI) resulting from cardiopulmonary resuscitation (CPR) is rarely reported and most reports are of aortic rupture. Clinical reports have also documented aortic dissection and intramural hematomas with sequential imaging showing the development of these aortic injuries after the administration of CPR, suggesting that non-transmural aortic injury may also result from CPR. We report partial separation of an aortic intimal atheromatous plaque as a component injury in a case with multiple complications of manual CPR. A 74-year-old male presented to the emergency room (ER) with a 2-day history of chest pain. While in the ER, he suffered witnessed cardiac arrest and resuscitative attempts were pursued for 60 min prior to declaring death. At autopsy, there were numerous injuries attributable to CPR, including bilateral rib fractures, sternal fracture, retrosternal and mediastinal hemorrhage, epicardial ecchymoses, and ruptured pericardium. There was a perforated inferior wall myocardial infarct with a large left hemothorax. There was partial separation/laceration of an intimal atheromatous plaque on the anterior wall of the ascending aorta proximal to the origin of the brachiocephalic artery, forming a triangular flap, without associated intramedial dissection or hematoma. There was no thrombus formation, effectively excluding existence of the laceration prior to circulatory arrest. This aortic injury provides pathologic confirmation of non-transmural BTAI definitively sustained during manual CPR. Pathologists and clinicians alike should be cognizant of the possibility of BTAI resulting from CPR, which may manifest the full range of severity from intimal tear through aortic rupture.
