Femoral vein catheter placement under direct ultrasound guidance

Operator inserting a needle into the common femoral vein under direct ultrasound guidance. A transverse position of the transducer in relation to the vein is recommended so that the operator can see the needle tip enter the center of the vein lumen. With a longitudinal approach, the entire needle course is seen in one image, but it is possible to be at or near the side wall of the vessel without realizing it.
