Cyanosis produced by superior vena caval stenosis

Abstract

Superior vena cava syndrome is a rare complication of pacemaker implantation. Narrowing and occlusion of the superior vena cava is often asymptomatic due to the formation of decompressive collateral pathways to the right atrium. We present a case in which an anomalous venous pathway allowed decompression of the systemic venous return into the left atrium, resulting in arterial desaturation, cyanosis, and fatigue.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
