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.
