What is a potential risk if a catheter tip malpositions into the azygos vein?

When a catheter tip is malpositioned into the azygos vein, the primary concern is that the catheter may not be effectively delivering fluids or medications to the intended location, such as the superior vena cava. This misplacement necessitates intervention to ensure proper function and safety of the vascular access device.

Repositioning or replacing the catheter is critical because if the device remains in the azygos vein, it could lead to complications such as inadequate treatment delivery or potential occlusion. Additionally, leaving the catheter inappropriately positioned may increase the likelihood of adverse effects, such as thrombosis or diminished venous access efficacy.

While potential risks like infection, embolism, or even the need for immediate device removal could arise from catheter misplacement, these concerns are secondary to ensuring proper placement and function of the catheter. Therefore, the focus should be on addressing the positioning issue immediately to prevent further complications.
