Subclavian steal syndrome
Subclavian Steal Syndrome
Subclavian Steal Syndrome (pronunciation: sub-CLAY-vee-an steal SIN-drome) is a medical condition characterized by the reversal of blood flow in the vertebral artery or the internal thoracic artery due to a stenosis (narrowing) or occlusion (blockage) in the subclavian artery.
Etymology
The term "Subclavian Steal Syndrome" is derived from the Latin words "sub" (under), "clavis" (key or bar), referring to the location of the subclavian artery beneath the clavicle, and the English word "steal", which refers to the diversion of blood flow.
Symptoms
Symptoms of Subclavian Steal Syndrome may include dizziness, fainting, ataxia (lack of muscle control), and possibly ischemic symptoms in the affected arm such as pain, pallor, and pulselessness.
Diagnosis
Diagnosis of Subclavian Steal Syndrome is typically made through Doppler ultrasonography, Magnetic Resonance Angiography (MRA), or Computed Tomography Angiography (CTA).
Treatment
Treatment options for Subclavian Steal Syndrome may include medication, angioplasty, or surgical revascularization.
