A Case of Multiple Vein Thrombosis Following Pacemaker Implantation

Pacemakers are implanted as part of the treatment process of conditions including symptomatic bradycardia and certain types of heart block. One complication associated with pacemaker implantation is upper extremity deep venous thrombosis (UEDVT), which can subsequently lead to pulmonary embolism, limb loss, or death. We present the case of an 88-year-old male who developed UEDVT in his left subclavian, axillary, brachial, and basilic veins shortly after dual chamber pacemaker implantation for treating symptomatic heart block. The patient received anticoagulation with intravenous heparin while inpatient but was switched to oral apixaban prior to discharge. This case highlights the importance of detecting and treating UEDVT in patients who recently underwent pacemaker placement.
