It is usually unilateral, as the origin of PICA arises from a single. The Posterior Inferior Cerebellar Artery (PICA) carries blood to this part of the brain. ![]() The involvement of these arteries and parts of the brain is where many of the other names for the condition originate.Įvidence notes that hypertension is the most common risk factor for Wallenberg syndrome. Strokes in the distribution of the posterior inferior cerebellar artery (PICA) are rare. An insufficient blood supply can damage the lateral part of the medulla oblongata, resulting in the symptoms of Wallenberg syndrome. The brainstem is a lower extension of the brain and is responsible for many important functions, such as eye movement, balance, and swallowing. Dizziness is another major symptom of this type of stroke. They may have hoarseness and trouble swallowing. They may also have numbness on one side of the face and body and an eye droop. This stroke (Wallenberg’s Syndrome) causes the person to have balance problems and lean to one side. This area of the brain includes the different parts of the brain stem, most notably the medulla oblongata. Artery (PICA) carries blood to this part of the brain. This results in insufficient blood reaching the posterior, or back, portion of the brain. Specifically, a blockage occurs in the vertebrobasilar system, most commonly in the posterior inferior cerebellar artery, or the vertebral artery. When oxygenated blood does not reach part of the brain due to a blockage, that part of the brain may become damaged or die. Wallenberg syndrome occurs due to an ischemic stroke occurring in one of the arteries that supply blood to the back portion of the brain.
