Intrapericardial caval injury due to blunt trauma.
BACKGROUND
Report of diagnosis and treatment of intrapericardial vena caval injury caused by blunt thoracic trauma, an unusual cause of cardiac tamponade.


METHODS
A 43-year-old male motor vehicle accident victim suffered a lacerated intrapericardial inferior vena cava leading to cardiac tamponade. Positive clinical findings were hypotension and tachycardia without indication of external chest trauma.


RESULTS
Abdominal computed tomography was negative, but ultrasound demonstrated cardiac tamponade and fluid in the abdomen. Pericardiocentesis was performed, and nonclotted blood was aspirated. Laparotomy showed intra-abdominal blood and splenic capsule avulsion. Sternotomy revealed a laceration of the inferior vena cava, which was repaired.


CONCLUSIONS
Signs of cardiac tamponade and a history of blunt thoracic trauma caused by deceleration injury suggests intrapericardial inferior vena cava injury. Median sternotomy is the optimal choice for caval repair.
