Superior ulnar collateral artery medial epicondyle, to anastomose with the anterior ulnar recurrent. Superior ulnar collateral artery The superior ulnar collateral artery (inferior profunda artery), of small size, arises from the brachial artery a little below the middle of the arm; it frequently springs from the upper part of the a. profunda brachii. It pierces the medial intermuscular septum, and descends on the surface of the medial head of the Triceps brachii to the space between the medial epicondyle and olecranon, accompanied by the ulnar nerve, and ends under the Flexor carpi ulnaris by anastomosing with the posterior ulnar recurrent, and inferior ulnar collateral.
Brachial plexus block of the integrity of the skin, brachial plexus block can be associated with infection or bleeding. In people who are using anticoagulant agents, there is a greater risk of complications related to bleeding. Complications associated with brachial plexus block include intra-arterial or intravenous injection, which can lead to local anesthetic toxicity. This may be characterized by serious central nervous system problems such as epileptic seizure, central nervous system depression, and coma. Cardiovascular effects of local anesthetic toxicity include slowing of the heart rate and impairment of its ability to pump blood through the circulatory system, which may lead to circulatory
