[Superior vena cava syndrome after pacemaker implantation. Increased risk with DDD-systems? Case report].

Superior vena cava syndrome due to transvenous pacing leads is a rare event. Local infection as well as multiple leads are important predisposing factors. The case of a patient with superior caval syndrome after multiple complicated permanent pacemaker insertions is presented. Medical treatment was unsuccessful. At operation a fibrous narrowing of the vena cava superior was found. The two leads (DDD-pacemaker) were left in place. A Goretex patch was used for enlargement of the anterior wall of the vein. Postoperatively, the patient remained free of symptoms and the vein was patent angiographically. In case of failure of medical management surgical correction should be attempted without delay.
