Intermittent subclavian vein obstruction

Primary Subclavian-Axillary Vein Thrombosis

“…36 40 This entity cannot be differentiated from primary thrombosis without studies of venous pressure or venography. A minimally adequate angiographic study must include serial films-at least two within the first 10 sec of injection and preferably a late film 5 or 10 sec later.…”

Benign obstruction of subclavian and axillary veins possibly due to filariasis

“…Thrombosis itself has not been a constant feature and surgery has often not disclosed any evidence of a thrombus. The occlusion could be extravenous such as a mechanical obstruction caused by a pre-venous accessory phrenic nerve (Jackson and Nanson, 1961). Trauma in the form of several types of activity has been cited as the precipitating cause, e.g.…”

Pain in Shoulder and Arm

“…The many denominations for the few types of occlusion of the deep veins in the upper limbs reflect the rather inaccurate understanding of the situations (5,9,10,18,19,20,21,24,37,43,47,74,80,85,86,87,88,92): -"Effort," "idiopathic," "primary," "secondary," "subclavicular," "stress," "morning," "spontaneous subclavian," "iatrogenic," ... thromboses (1, 3, 16, 23, 47, 58, 61, 62, 75) -"Paget-Von Schrotter" syndrome (29,31,43,61) -"Axillary," "subclavian," "axillo-subclavian" ... occlusion or thrombophlebitis (23, 32, 45, 72) -"Venous claudication," -"Venospasm," -"Intermittent venous occlusion" (2,27,41,44,45,56,57,76,77,91) -Element of a "brachial plexus," "costoclavicular," "thoracic outlet," "thoracic inlet," "thoracic aperature," "scapular girdle," "shoulder girdle," "upper limb hilus," "hyperabduction," "thoracic outlet compression" "thoracic operculum," "scalenius anticus," "scapulo-thoracic passage," ... syndromes (4,13,25,32,33,45,49,50,52,53,57,…”

“…The pre-existing stretching or compression-producing mechanisms are usually due to the presence of: congenital abnormal structures, such as cervical ribs or fihrous bands (4,12,33,52,67,85,86), unusual position of an accessory phrenic nerve (43,44), an atypical artery (41,43,86), or a malpositioned subclavian vein terminal valve (17,23,47,76,77,91). an atypical, congenital or acquired, topographic arrangement of normal or abnormal anatomical elements.…”

“…Type I Extrinsic compression without significant lesion of the vein wall (2,17,23,27,29,30,31,41,43,44,45,56,57,76,77,86,91) The narrowing of the lumen of the vessel varies widely with the anatomical arrangements in each individual, and the position of the arm and shoulder with regard to the thorax.…”
