Pacemaker İnduced Superior Vena Cava Syndrome and Subclavian Vein Stenosis: Case Report and Systematic Review

Superior vena cava (SVC) is the biggest venous channel carrying blood from head, upper extremities and upper thorax to the heart. Subclavian vein is almost always utilized during pacemaker implantation. Although venous stenosis after pacemaker implantation is a common complication, most of the patients remain asymptomatic. SVC syndrome is a serious but very rare complication of pacemaker implantation. Here, we report a patient with SVC syndrome and concomitant subclavian stenosis due to pacemaker implantation 20 years ago. Different treatment strategies are available but sometimes as in our case, it may be difficult to treat.
