Abstract: Introduction: Chest X-ray is the most commonly used method to verify the placement of central venous catheters, including peripherally inserted central catheters (PICCs). The caval-atrial junction (CAJ), the area between the end of the superior vena cava and the right atrium, is the recommended site for proper PICC placement. This chapter addresses the identification of the catheter at the CAJ through chest X-ray and the anatomical landmarks used for its localization. Objective: To identify the anatomical structures guiding the identification of PICC placement in chest X-rays, enhance understanding of complications resulting from improper PICC positioning, broaden knowledge on PICC repositioning techniques, and expand awareness of other technologies available for PICC localization at the CAJ. Method: This is a descriptive study of various models and methods for verifying the position of central catheters. Results: The methods used to measure the catheter size required for achieving optimal positioning at the caval-atrial junction in adults, children, and neonates in upper and lower limbs before insertion are described. Confirmation methods of positioning through anatomical points on X-rays, such as the carina, third intercostal space, and vertebral body unit, are also outlined. Complications arising from improper positioning and PICC repositioning techniques are described. Finally, other technologies used for catheter tip confirmation, such as fluoroscopy, ultrasound, and intracavitary electrocardiogram, are discussed.
