What Are The Signs Of Subclavian Steal Syndrome?

Lightheadedness

Subclavian steal syndrome patients can experience lightheadedness or unsteadiness. This symptom is different than vertigo, even though both are associated with each other. Vertigo has a component of spinning to it while lightheadedness does not. The lack of blood supply from the vertebral arteries can cause the part of the brain called the cerebellum to be starved of oxygen. The cerebellum is the part of the brain responsible for functions such as posture, balance, and movement coordination. These functions may become compromised, resulting in lightheadedness. Additionally, the brain stem is also fed oxygenated blood by the vertebral arteries and may become starved of oxygen in affected individuals. The brain stem is responsible for the regulation of many autonomous nervous functions, including blood pressure, heart rate, breathing, and consciousness. Lightheadedness may occur as a result of the cells in the brain stem shutting down because of an inadequate supply of oxygen. If these cells continue to be deprived of oxygen following the onset of lightheadedness, the affected individual may lose consciousness.
