Possible arterial accesses for Seldinger-punction?A. Radial arteryB. Common femoral arteryC. Brachial arteryD. External carotid artery

The Seldinger technique is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named after Dr. Sven Seldinger, a Swedish radiologist who introduced the procedure in 1953. The following arteries can be accessed using the Seldinger technique:

A. Radial artery: This is one of the two major arteries of the forearm, often used because it is easily accessible and has less risk of complications.

B. Common femoral artery: This is a large artery in the thigh and a commonly used access site for many procedures, including angiography, angioplasty, and stent placement.

C. Brachial artery: This is the major blood vessel of the upper arm and is often used for procedures involving the upper extremities or when other access sites are not suitable.

D. External carotid artery: This artery supplies blood to the face and neck. It is less commonly used as an access site because of the risk of stroke, but may be used in certain situations.

Each of these arteries can be accessed using the Seldinger technique, but the choice of artery depends on the specific procedure and the patient's individual anatomy and condition.
