Disease relevance of Ulnar Artery

• A pathological specimen of the ulnar artery from one patient showed severe luminal narrowing by an acellular material with no evidence of atheroma [1].
• Foscarnet: a possible cause of ulnar artery thrombosis in a patient with AIDS [2].
• METHODS: Nine cadavers embalmed with formaline were dissected under loupe magnification (x4) from the wrist proximally to the proximal phalanx of the small finger distally, delineating the branches of the ulnar artery along the ADM and FDM muscles [3].

High impact information on Ulnar Artery

• In type I there was a single midline superficial vessel with no radial or ulnar artery [4].
• Dissection was commenced distally near the wrist and extended proximally to where the ulnar artery passed between the two heads of origin of the flexor digitorum superficialis [5].
• This study investigates the association of inspiratory flow rate and volume to the level of vasoconstrictor reflexes in the 4th digit tip skin and the ulnar artery in 12 healthy volunteers (age range 21-65, mean 38.1 years) [6].
• We present the case of 21-year-old female who applied three dissolved Flunitrazepam tablets into the ulnar artery and was successfully treated with prostaglandin E1 and recombinant tissue plasminogen activator [7].
• Step Three (Surgical): Fasciotomy of the volar carpal ligament to lengthen the ulnar leaf of the TCL; permits visualization of the ulnar artery and neurolysis of the ulnar motor nerve [8].

Anatomical context of Ulnar Artery

• There were no injuries noted in any of the vital structures including the ulnar artery, superficial palmar arch, third common digital nerve or flexor tendons [9].
• The modified approach, which includes specific localization of the hook of the hamate, flexor retinaculum, and the superficial palmar arch utilizing topographical landmarks, avoids entry into Guyon's canal and injury to the ulnar artery and nerve, median nerve, and common digital nerves [10].
• Occlusion of the ulnar artery, leaving the radial artery as the dominant supply, resulted in fluorescein perfusion of the entire hand [11].
• 2 The infusion is administered over 4 h: Radial or ulnar artery 10 ml 20% calcium gluconate in 40 ml normal saline, or brachial artery: 20 ml 20% calcium gluconate in 80 ml normal saline [12].
• With regard to the ulnar nerve, the volar approach is used, where the needle passes through or medial to the flexor carpi ulnaris tendon; however, the ulnar artery is at risk because the needle may accidentally penetrate it, causing profuse bleeding [13].

Associations of Ulnar Artery with chemical compounds

• We present a case of accidental injection of oral methadone and flunitrazepam into the ulnar artery, with resultant severe ischaemia of the hand [14].
• Nifedipine in ulnar artery occlusion [15].

Gene context of Ulnar Artery

• Based on the ulnar artery distal to the common interosseous branch it may include muscle (FCU) tendon (PL) and bone (ulna) [16].
