Deep artery of arm Deep artery of arm The deep artery of arm (also known as arteria profunda brachii and the deep brachial artery) is a large vessel which arises from the lateral and posterior part of the brachial artery, just below the lower border of the teres major. It follows closely the radial nerve, running at first backward between the long and medial heads of the triceps brachii, then along the groove for the radial nerve (the radial sulcus), where it is covered by the lateral head of the triceps brachii, to the lateral side of the arm; there it pierces the lateral
Brachial plexus block subjected himself to the supraclavicular block. Later that year, Georg Hirschel (18751963) described a percutaneous approach to the brachial plexus from the axilla. In 1928, Kulenkampff and Persky published their experiences with a thousand blocks without apparent major complications. They described their technique with the patient in the sitting position or in the supine position with a pillow between the shoulders. The needle was inserted above the midpoint of the clavicle where the pulse of the subclavian artery could be felt and it was directed medially toward the second or third thoracic spinous process. By the late 1940s, clinical experience
