Superior vena cava syndrome after pacemaker implantation treated with direct oral anticoagulation

Abstract

Abstract Background Superior Vena Cava (SVC) syndrome, is a quite rare but serious complication after pacemaker lead implantation; most patients are asymptomatic due to the development of adequate venous collateral circulation. Case presentation We report a case of a 75-year-old woman who developed SVC syndrome after transvenous pacemaker implantation with complete resolution of the thrombosis after 3 months of oral anticoagulation. Conclusions Generally other causes as malignancy are considered to be the most common etiology of SVC syndrome, but benign iatrogenic causes, mainly intravascular devices (central vein catheters, cardiac defibrillators and pacemaker wires), are becoming increasingly common. Procedures performed on venous vasculature, causing a possible intimal injury or vein stenosis, provoked by transvenous leads, seem to be the most reasonable explanation for the observed complication.
