RT Journal Article SR Electronic T1 Superior vena cava syndrome after open heart surgery JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 93 OP 95 VO 59 IS 1 A1 Maggiano, H.J.

YR 1992 UL http://www.ccjm.org/content/59/1/93.abstract AB Superior vena cava syndrome is an uncommon complication of open heart surgery. While both cardiac tamponade and superior vena cava syndrome may present as elevated central venous pressure accompanied by decreased mean arterial pressure and cardiac output, the presence of upper body cyanosis is unusual with tamponade. We report the diagnosis and successful emergency treatment of a patient with acute superior vena cava syndrome and dyspnea apparently caused by a pericardial hematoma developing after aortic valve replacement and coronary artery bypass grafting.
