title: Tunneled-cuffed catheter implanted into the accessory hemiazygos vein because of occlusion of the left innominate vein.
abstract: Hemodialyzed patients are at risk of multiple catheterizations. Nephrologists performing such procedures need to be familiar with congenital and acquired vascular abnormalities. We describe a successful insertion and use of a cuffed-tunneled catheter in a patient with unusual anatomy of the central venous system. Computed tomography angiography revealed thrombosis of the right subclavian vein and bilateral occlusion of innominate veins. The left internal jugular and subclavian veins joined to form a large vessel that drained through the accessory hemiazygos and azygos veins into the superior vena cava. The catheter was implanted through the left internal jugular vein into the accessory hemiazygos vein. The presented case demonstrates that the catheter can be implanted into distended collateral, especially when no other location is possible.
