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.

The value of the left apical cap in the diagnosis of aortic rupture: a prospective and retrospective study.

The authors conducted a prospective and retrospective study of the radiographic findings in 45 patients with traumatic rupture of the aorta. In 7 cases, a left apical cap was the only clearly visible abnormality. In 11 cases a cap was present together with a poorly defined aortic knob, while in 13 cases both were seen along with mediastinal widening. In 14 cases, all of the classical signs of aortic rupture were present, but an apical cap was not seen or was not considered significant. Of 32 aortograms obtained, 12 were taken solely because of an apical cap; 2 were positive for aortic rupture and 10 were negative. No aortic rupture was found in patients with a left apical cap and fractures of the ribs, vertebral bodies, or scapulae.

Benign pneumoperitoneum following median sternotomy incision.

Because of the close anatomic relationship of the pericardium, diaphragm, and peritoneal cavity, a benign pneumoperitoneum may occur following median sternotomy incision and cardiac surgery. The pneumoperitoneum results from inadvertent opening of the peritoneal cavity during the initial surgical incision or during the subsequent cardiac surgery. It is generally of no significance to the patient, although it must be distinguished from pneumoperitoneum occuring secondary to intraabdominal pathology or to retrograde dissection of extraalveolar air in patients on ventilatory support. Two illustrative cases are presented.
