Aspiration of a foreign object is uncommon in a patient with a tracheostomy. The following case history describes the consequences of failure to diagnose an aspirated object and how the aspiration of an exfoliated tooth can occur despite the presence of a tracheostomy tube. Dentists play an important role in preventing foreign body aspiration in debilitated patients.
Rupture of an atherosclerotic abdominal aortic aneurysm into the inferior vena cava presents a challenging surgical problem. Marked hemodynamic changes are produced by the large arteriovenous shunt. Hemodynamic monitoring with a Swan-Ganz catheter will quantitate these alterations and can help direct appropriate therapy. A case illustrating this unusual lesion and the preoperative, intraoperative and postoperative cardiovascular changes is presented.
