Abstract

The subclavian vein is an uncommon route for tunneled hemodialysis catheter (tHDC) placement because of its potency for future dialysis access. However, when favored access routes have been exhausted because of repeated catheterization or limited life expectancy, the subclavian vein can be used for urgent hemodialysis. A subclavian catheterization has a technical problem. The subclavian vein often forms a right angle with the vena cava, and advancing stiff peel-away sheath can cause a vascular injury. However, raising the patient’s arm can alter the position of the guidewire and, therefore, change the angle of the vein favorable for tHDC placement. Herein, we report two patients who underwent subclavian catheterization; one experienced an injury to the superior vena cava after undergoing the conventional procedure, whereas the other patient with raised arm during the catheterization procedure had safe catheter placement.
