Inferior ulnar collateral artery the anterior ulnar recurrent. Behind the medial epicondyle a branch anastomoses with the superior ulnar collateral and posterior ulnar recurrent arteries. Inferior ulnar collateral artery The inferior ulnar collateral artery (anastomotica magna artery) is a artery in the arm. It arises about 5 cm. above the elbow from the brachial artery. It passes medialward upon the Brachialis, and piercing the medial intermuscular septum, winds around the back of the humerus between the Triceps brachii and the bone, forming, by its junction with the profunda brachii, an arch above the olecranon fossa. As the vessel lies on the brachialis, it gives
Ankle–brachial pressure index ABPI is the ratio of the highest ankle to brachial artery pressure. An ABPI between and including 0.9 and 1.2 considered normal (free from significant PAD), while a lesser than 0.9 indicates arterial disease. An ABPI value of 1.3 or greater is also considered abnormal, and suggests calcification of the walls of the arteries and incompressible vessels, reflecting severe peripheral vascular disease. Provided that there are no other significant conditions affecting the arteries of the leg, the following ABPI ratios can be used to predict the severity of PAD as well as assess the nature and best management of various
