The effects of a pericardial collection are dictated by the finite compliance of the pericardium, whereas the boundaries and compliance of the structures surrounding a mediastinal hematoma are much less predictable. Although the mediastinal hematoma is extrapericardial, it initially may be difficult to differentiate from intrapericardial blood or a loculated pericardial effusion. Right pleural effusion […]

Two-dimensional echocardiography enabled the direct visualization of a rare and unusual sequelae of blunt anterior chest trauma: the formation of a localized anterior mediastinal hematoma causing extrapericardial cardiac tamponade. The visualization of a Swan-Ganz catheter in the twodimensional echocardiogram aided in confirming the location of both the obliterated right ventricular chamber and the right ventricular […]

An aortic arch arteriogram was normal, and the patient was observed after laparotomy in the Surgical Intensive Care Unit. On arrival to the Surgical Intensive Care Unit, the blood pressure was 120/80 mm Hg, with a pulse of 110 beats per minute. Within the following three hours, blood pressure fell to 80/50 mm Hg, and […]

In: Chest Trauma

Extrapericardial Cardiac Tamponade by a Mediastinal Hematoma Cardiac tamponade may result from a variety of intraper-icardial or extrapericardial sources of compression of the heart and great vessels. Postoperative tamponade following open-heart surgery is a well-known entity caused by either hemorrhage within the pericardial sac or by mediastinal hematoma formation. Mediastinal hematoma has been reported in […]
