Spontaneous aorto-vena caval fistula: hemodynamic monitoring.
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.
