Superior Vena Cava Syndrome after Epicardial Pacing Wires Removal.

Abstract: Although most superior vena cava (SVC) syndromes are due to intrathoracic malignancies, some are iatrogenic, such as those following the intravenous implantation of pacemaker wires. To date, the occurrence of this syndrome after epicardial pacemaker removal has not been described. The initial auricular laceration after removal can be complicated by the administration of anticoagulant and antiplatelet drugs, forming a hematoma that compresses the SVC cranially. Therefore, standardized practice may be necessary in these patients to address anticoagulant and antiplatelet therapy, perform serial echocardiography, and pay attention to underlying symptoms, which may be insidious and delayed.
