Misplaced Central Venous Catheter in the Left Hemiazygos Vein; A Case Report

Abstract

Introduction:The structure of the hemiazygos vein is often different in different individuals There is a normal variation that connects the ascending hemiazygos vein to the left innominate vein, parallel with the subclavian and internal jugular veins.Case Presentation:A 33-year-old man who was a known case of End Stage Renal Disease (ESRD) was admitted to the emergency department due to Double Lumen (DL) dysfunction. The emergency physician inserted DL in his left jugular vein on the ultrasound guide. The result of angiography showed that DL was placed in his left hemiazygos vein.Conclusions:This condition should be considered as part of the anatomical variation of the left hemiazygos vein during DL insertion by emergency physicians.
