Bilateral internal mammary artery laceration after cardiac pulmonary resuscitation.

Cardiopulmonary resuscitation (CPR) is essential for the survival of cardiac arrest patients. High-quality chest compressions are critical for survival, but energetic resuscitation efforts can lead to chest injuries. Internal mammary artery (IMA) injury is a rare complication of CPR, but can lead to life-threatening intrathoracic hemorrhage. Early detection of IMA injury should be considered in all post cardiac arrest syndrome (PCAS) with anemia refractory to transfusion. To the best of our knowledge, no cases of CPR-associated bilateral IMA laceration have ever been reported. We report a unique CPR complication resulting in anterior mediastinal hemorrhage that was detected by ECHO, verified by computed tomography angiography, and treated with endovascular intervention.
