Cardiac tamponade after blunt trauma is rare and usually associated with rupture of cardiac chambers on the relatively weaker right side. Aortic injury causing tamponade after blunt trauma is an even rarer catastrophic injury that leads to death. Blunt trauma can inflict injury to the aorta through several mechanisms. Most aortic injuries caused by blunt trauma present as aortic dissection or rupture of the aortic isthmus due to indirect forces. Direct injury of the aorta can sometimes be caused by a fractured bone fragment. Several cases of delayed aortic injury caused by rib fracture have been reported. However, almost all cases involved the descending aorta owing to a posterior rib fracture. In our case, a laceration-type wound approximately 7 mm in size with 2 mm perforation was found at the level of perforated pericardium. To our knowledge, delayed ascending aortic perforation after blunt trauma has not been reported. We describe a case of cardiac tamponade associated with delayed ascending aortic perforation 2 weeks after blunt trauma...
