Table 1 (abstract P194). Minimal guidewire length = 105 mm (95th percentile of the vessel length) + 30 mm (to ensure that the guidewire J-tip passes the junction of the right and left brachiocephalic veins and the azygos arch into the lower part of the superior vena cava) + steel cannula length (the maximum length that can be inserted into the patient) + CVC full length + 10 mm (the part of the guidewire that must extend from the CVC before CVC-insertion)
