title: Permanent transvenous pacemaker implantation following percutaneous transluminal angioplasty in a patient with asymptomatic bilateral subclavian vein stenosis.
abstract: Subclavian venous obstruction is a disorder that arises more frequently today, due to the increased frequency of vascular interventions. It may affect one or both of the subclavian veins. When bilateral, it complicates the implantation of several devices that are preferably installed via the upper-extremity veins. Among these are pacemakers, cardiac defibrillators, catheters for haemodialysis, and even port catheters. In this study, we present a patient with symptomatic Mobitz type II AV block, who was planned to undergo a pacemaker implantation. Previously the patient had undergone two coronary bypass operations. Probably due to the interventions made at that time, he was now diagnosed with bilateral subclavian vein obstruction. Following the diagnosis, the obstruction in the right subclavian vein was successfully relieved through balloon angioplasty, after which a permanent atrioventricular pacemaker was installed.
