Although the CICCs can be inserted by puncture and cannulation of at least six different veins (internal jugular, external jugular, subclavian, brachio-cephalic, axillary, cephalic), it is generally preferable to have an exit site located in the infra-clavicular site, as this is characterized by greater stability of the dressing and less bacterial contamination.
This can be achieved by ultrasound-guided puncture of the axillary vein in the infra-clavicular area, using either the short-axis visualization technique with 'out of plane' puncture or the long-axis visualization with an 'in plane' puncture.
