What is subclavian steal syndrome

    • What is the prognosis of for subclavian steal syndrome?

      Prognosis Subclavian steal syndrome is a relatively benign condition. As it is a marker of atherosclerosis, it can indicate the risk for future events like myocardial ischemia or stroke. Hence, secondary preventive measures in patients can help in a good prognosis.

    • What happens if the subclavian artery is blocked?

      Blood flow to both the affected subclavian artery (which supplies the arm) and the vertebral artery are thus diminished. When this happens, blood can flow in the reverse direction (away from the brain) in the affected vertebral artery, to supply the blocked subclavian artery.

    • What is the treatment for steal syndrome?

      Treatment of Subclavian Steal Syndrome Open Surgical Procedures. In this procedure, the artery is opened and the plaque, diseased intima, and internal elastic lamina of the vessel are removed. Surgical Bypass or Transposition. Extrathoracic carotid-subclavian bypass using 6- to 8-mm Dacron or polytetrafluoroethylene (PTFE) prosthetic grafts are used. Axillary-axillary bypass. ...

    • What is vascular access steal syndrome?

      Vascular access steal syndrome. In nephrology, vascular access steal syndrome is a syndrome caused by ischemia (not enough blood flow) resulting from a vascular access device (such as an arteriovenous fistula or synthetic vascular graft–AV fistula) that was installed to provide access for the inflow and outflow of blood during hemodialysis.

    • Subclavian Steal Syndrome: Background, Pathophysiology, Etiology

      steal syndrome: Stenosis of the subclavian artery before the origin of the vertebral artery results in a backflow of blood from the vertebral artery to fill the vessels distal to the stenosis – reduced cerebral blood flow results. Signs: lower BP and pulse in the affected arm + claudications.

      Steal syndrome is a decreased and potential reversal of blood flow distal to the site of an AV fistula and blood is being “stolen” from the distal area (Reifsnyder & Arnaoutakis, 2010). A DRIL procedure is a procedure in which “the site of the steal is bypassed, and the native vessel just distal to the steal site is ligated” (Hubbard ...
