TOS can involve only part of the hand (as in the pinky and adjacent half of the ring finger), all of the hand, or the inner aspect of the forearm and upper arm. Pain can also be in the side of the neck, the pectoral area below the clavicle, the armpit/axillary area, and the upper back (i.e., the trapezius and rhomboid area).
Thromboangiitis obliterans, also known as Buerger disease (English / ˈ b ɜːr ɡ ər /; German: [ˈbʏʁɡɐ]) or Winiwarter-Buerger disease, is a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet.
The condition is thought to be the result of inflammation or mechanical damage by blood pressure [30] around long axis of medular veins. Dawson's fingers spread along, and from, large periventricular collecting veins, and are attributed to perivenular inflammation. [36] Lesions far away from these veins are known as Steiner's splashes. [30]
Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage. Although both occur in vasculitis, inflammation of veins or arteries on their own are separate entities.
Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [2]: 826–7 [3] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and,less commonly, infection of the vein.
Ulnar deviation, also known as ulnar drift, is a hand deformity in which the swelling of the metacarpophalangeal joints (the big knuckles at the base of the fingers) causes the fingers to become displaced, tending towards the little finger. [1]
The dorsal venous network of the hand is a venous network on the dorsum (backside) of hand. It is formed by the dorsal metacarpal veins (three in number), a dorsal digital vein from the radial (lateral) side of the index finger and one from the ulnar (medial) side of the little finger, and both dorsal digital veins of the thumb.
It can take place in several locations in the human body but is observed most often in the extremities. The fingers are especially common because they are exposed most often. [citation needed] When the fingers are exposed to cold, vasoconstriction occurs first to reduce heat loss, resulting in strong cooling of the fingers. Approximately five ...
