Subclavian Carotid Artery Steal Syndrome refers to a medical condition characterized by abnormal blood flow patterns in the arteries of the neck, particularly involving the subclavian and carotid arteries.
The subclavian arteries are responsible for supplying oxygen-rich blood to the arms, while the carotid arteries provide blood flow to the brain. In Subclavian Carotid Artery Steal Syndrome, a blockage or narrowing in one of the subclavian arteries causes blood to be diverted away from the carotid arteries towards the arms, thus "stealing" blood from the brain.
This diversion of blood flow deprives the brain of the necessary oxygen and nutrients, leading to a variety of symptoms. Common symptoms of Subclavian Carotid Artery Steal Syndrome include dizziness, vertigo, weakness or numbness in the arms or hands, difficulty with coordination, and in severe cases, syncope (fainting).
The underlying cause of Subclavian Carotid Artery Steal Syndrome is typically atherosclerosis, a condition characterized by the buildup of fatty plaques in the arteries. Other risk factors may include smoking, hypertension, and diabetes.
Diagnosis of Subclavian Carotid Artery Steal Syndrome often involves medical imaging techniques such as angiography, Doppler ultrasound, or magnetic resonance imaging (MRI). Treatment options may include medication to manage symptoms, lifestyle modifications to reduce risk factors, and in some cases, surgical intervention to address the blockage or stenosis in the affected artery.
