Superior vena cava syndrome due to transvenous pacing leads is an uncommon
but potentially life-threatening complication. This case involves a 54-year
-old man who developed left innominate vein occlusion due to a pacemaker le
ad. This complication induced a progressive swelling on the left side of hi
s face, neck, arm, and upper chest. The left innominate vein occlusion was
surgically treated using a composite spiral saphenous vein graft. Postopera
tively, the patient has received anticoagulation therapy with warfarin to p
revent thrombosis and, thereby, the long-term patency of the graft. He has
undergone follow-up on a regular outpatient basis without showing any recur
rence of clinical symptoms.
