  • There are multiple processes that can cause obstruction of the subclavian artery before the vertebral artery, giving opportunity for SSS. (wikipedia.org)
  • TOS doesn't directly cause SSS, because the site of subclavian artery compression is over the first rib, which is distal to the vertebral artery. (wikipedia.org)
  • SSS results when the short low resistance path (along the subclavian artery) becomes a high resistance path (due to narrowing) and blood flows around the narrowing via the arteries that supply the brain (left and right vertebral artery, left and right internal carotid artery). (wikipedia.org)
