Catheterisation of a persistent left superior vena cava.

We present a case of a 62-year-old woman with end-stage renal disease who displayed a persistent left superior vena cava detected following placement of haemodialysis catheter through the left internal jugular vein (IJV). The diagnosis was confirmed by left internal jugular vein cathetogram, computed tomography (CT) thorax and transthoracic echocardiography. The catheter was removed without immediate complications. She remained well during the outpatient follow-up. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018. All rights reserved.
