Version June 2024
| Transverse ("out-of-plane") | Longitudinal ("in-plane") |
| Easier to see adjacent arteries and nerves at all times (preferred for internal jugular vein) | Higher risk of "sliding" off the vein and mistaking adjacent artery for the target vessel (preferred for superficial arm veins or during saphenous venous cannulation during venous ablation) |
| Easier to confirm compressibility of the vein | Better visualization of the entire vein, including presence of valves and changes in depth (preferred if trajectory of catheter wire is needed) |
| Easier for beginners to find and localize the needle, but precise location of the needle tip can be more challenging | More technically challenging to master, but improves visualization of entire needle and precise location of needle tip |
| Easier to correct left-right needle trajectory | Easier to see and correct angle of entry of the needle |
| Easier to ensure precise puncture of the 12 o'clock position of the vein | Easier to confirm successful passage of guidewire and make any necessary corrections |
