Can a left internal jugular catheter be used in the hemodialysis of a patient with persistent left superior vena cava?
A patient with a persistent left superior vena cava (PLSVC) was incidentally diagnosed after positioning of a dual lumen catheter for hemodialysis into the left internal jugular vein. Although PLSVC is a relatively rare condition, it is the most common congenital anomaly of thoracic venous circulation. It represents the persistence of the left horn of the embryonic sinus venosus, which normally involutes during embryogenesis to become the coronary sinus. The existence of a PLSVC can cause a significant diagnostic dilemma during catheterization of the left internal jugular vein, pertaining to the positioning of the catheter. It may also be associated with significant clinical implications such as systemic embolization, provocation of arrhythmia, and thrombosis of the vessel. The safety of such catheterization has not been adequately evaluated due to the rarity of this condition. We believe that a diagnostic workup including blood gas analysis, echocardiography, and computed tomography is necessary to confirm a right atrial drainage and a patent innominate vein as prerequisites to maintain the catheter in position.
