Acute vascular insufficiency in the upper limb suggests the possibility of
an embolic
phenomenon1-3.
The most common source of upper-extremity emboli is from the subclavian
artery, with less likely potential sources being the superficial palmar arch
and cardiac
vessels1. Thoracic
outlet compression represents the most frequently reported cause of subclavian
arterial
disease1,2,4,
and arterial-related problems associated with thoracic outlet compression,
although extremely uncommon, have also been
reported5. In
addition to the detection of historical features and the performance of
provocative maneuvers during the clinical examination, the use of noninvasive
magnetic resonance angiography has been reported to be particularly helpful in
the diagnosis of thoracic outlet
compression6,7.
