Severe superior vena cava syndrome after transvenous pacemaker implantation

Abstract

Superior vena cava syndrome is a rare complication after pacemaker implantation. The present report outlines how underestimation of clinically relevant symptoms of superior vena cava syndrome early after pacemaker implantation may result in severe complication with the need for major surgical intervention. Superior vena cava syndrome should be diagnosed early because immediate thrombolytic therapy is effective in the majority of patients and avoids the requirement for interventional or surgical efforts.
