The report may very well be a chronological description of the procedure, and should include:
*Position of the catheter tip in relation to the central veins (for example, in the inferior part of the superior vena cava)
*Presence or absence of fibrin sheath. The pattern of the outflow may be described. In case of a fibrin sheath, preferably report the distance between the tip and the point of contrast exit, and whether it occurs in a different vein.
Optionally, if tested or measured:
*Ability to aspirate.
