Infraclavicular Right Subclavian Vein in Pediatrics

The infraclavicular puncture of the subclavian vein, widely practiced under anatomical guidance, has a high incidence of complications reported in the medical literature. The implementation of ultrasound-guided puncture minimizes the risk of complications once proficiency in the technique is achieved. This procedure, performed in the long-axis (LAX) view, enhances the visualization and cannulation of the vein. The most complex aspect of the technique involves precise alignment of the puncture needle with the transducer’s insonation area; mastering this step significantly reduces apprehension regarding complications associated with this vascular access. It is important to note that the right subclavian vein (RSCV) is shorter than the left, and although the literature indicates a descending path toward the superior vena cava, there is a possibility of deviation toward the right internal jugular vein. Therefore, it is crucial to visualize the position of the guide before proceeding with the dilation and insertion of the catheter.
