Upper-extremity deep vein thrombosis and downhill esophageal varices caused by long-term pacemaker implantation

Upper-extremity deep vein thrombosis is common after pacemaker or cardioverter-defibrillator implantation. Only 1% to 3% of patients with upper-extremity deep vein thrombosis become symptomatic. Downhill esophageal varices develop in the upper third of the esophagus as a result of the obstruction of the superior vena cava. Herein, we report the case of a 54-year-old man--a recipient of multiple implanted cardiac pacemakers--who presented with bilateral upper-extremity deep vein thrombosis. This severely symptomatic condition was complicated by very rare and life-threatening downhill varices of the upper esophagus, but without bleeding. To the best of our knowledge, this is the 1st report of this array of conditions.
