“…The most common subtype of persistent left SVC results in the presence of both left and right SVCs 8,9 . More rarely, abnormalities of the embryological development lead to an absent right SVC with persistent left SVC, as previously described in both pediatric and adult patients [10][11][12][13][14][15][16] . In most cases, persistent left SVC drains into the right atrium via the coronary sinus with of no hemodynamic consequence 17 .…”

Persistence of left superior vena cava: a rare cause of hemodialysis tunneled catheter malposition

Hemodialysis central venous catheter (CVC) insertion can be complicated in patients with anomalous vessel anatomy. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. Central venous placement under ultrasound control has signiﬁcantly reduced the complications associated with blind puncture and allows an appropriate puncture of the desired vessel, but the CVC can still get misplaced if it follows an anomalous route. Herein, we report a case of dialysis catheter placed into a left sided superior vena cava, only diagnosed after CT scan study.
