Venous anatomy of the upper extremity

Hand position, transverse

Video 03-02: Hand Position Transverse

Using the hand position in the still image, the needle can be guided into the vessel using the follow-the-tip technique. This means that the needle is advanced until visible on the screen, then the probe is moved away from the needle until the bright white dot disappears. This process is repeated until the needle is well into the vessel.

Video 03-03: Upper Arm Anatomy

In the anterior upper arm, the humerus can be seen as the landmark deep on the screen. The brachial vein and artery can be seen running between the bicep and triceps muscles. Also visible is the basilic vein splitting off of the brachial, and the brachial nerve between the artery and vein.

US anatomy, forearm

Video 03-04: Forearm Anatomy

In the forearm the vein can be seen running superficial to the muscle body, and deep to the dermis. The radius can be seen as a landmark deep on the screen. Notice that it takes very little pressure to compress these veins (on the right side of the screen an uncompressed gel layer is a marker of the amount of pressure being applied).

Video 03-05: Accessing the Vessel in Transverse

This video shows the process of following the needle tip in the transverse or out-of-plane technique. As soon as the needle tip becomes visible (as a bright white dot), the operator stops advancing the needle and moves the probe away until the needle tip disappears. This process continues until the needle is hubbed in the vessel.
