The placement of a central venous catheter (CVC) has a 17.9% complication risk. Ultrasound guiding has been recommended as the gold standard of treatment to prevent problems and increase success rates. Ultrasound-guided cannulation, on the other hand, does not completely eliminate the risk of unintentional artery puncture. In a recent case report, the authors discussed how to prevent puncturing the subclavian artery during IJC cannulation.

A 3-year-old female kid weighing 16.9 kg with a midline brain stem tumour and hydrocephalus was posted for elective tumour removal in this case report. On the first attempt, the right IJV was pierced with the needle angled at a 45° angle to insert a CVC. Following blood aspiration, a guide wire was successfully fed through the needle, dilated, and a 5.5 Fr paediatric multi-lumen CVC with blue flex tip was placed. Free blood aspiration was tested at all three ports. A sterile clear dressing was placed to the CVC at the 8 cm point. An arterial waveform was seen when the transducer was attached to the CVC. Ultrasound imaging was used to check the catheter's location in the artery before it was removed. The puncture site and IJV were located slightly to the right of the carotid artery, as predicted. A pulsing vessel underneath the jugular vein, which might be the subclavian artery, was discovered after further scanning and changing probe angles (SA). The catheter was shown to pass into the internal jugular canal and then lay in the SA, which was unexpected.

Ultrasound indicated that the SA was around 2.5 mm deeper than the IJV. The needle tip entering the SA might be due to indentation of the IJV wall when puncturing the vein or displacement of the needle tip after the probe was withdrawn. There are five crucial aspects to remember while cannulating IJV in young patients with the SA just a few millimetres distant.

• First, during piercing, the needle should be maintained angulated in regard to the skin, close to 30° rather than 45°, since this tangential approach leads in reduced posterior forces that tend to collapse the vein wall. When the IJV diameter is smaller than the needle's longitudinal length of bevel, angulation may aid.

• Second, double wall puncture should be remembered where the vein diameter is limited.

• Third- When the needle approaches the vein and puncture is performed, it is critical that the tip of the needle be continually recognised using ultrasound.

• Fourth, before dilatation of the vessel, ultrasonography should be used to validate the course of the guide wire.

• Finally, in youngsters, a higher neck approach may be used to extend the distance between the IJV and the SA, lowering the risk of unintentional puncture.
