What is medulla compression?

Anterolateral compression of the medulla oblongata is the most common cause of VACS. The pulsatile impact of a tortuous vertebral artery on an impingement location may be responsible for patients with recurrent symptoms or transient symptoms.

What causes brainstem compression?

Infratentorial lesions at risk for a direct brainstem compression may be of various origin: spontaneous (cerebellar haematoma or ischaemia), traumatic (cerebellar contusion, epidural haematoma), neoplastic (metastasis or primitive brain tumour), infective (abscess).

What is brainstem compression?

Basilar invagination is a condition in which a vertebra (bone) at the top of the spine moves up and back, toward the base of the skull. In this abnormal position, the bone may compress the brain stem and spinal cord.

What happens if the vertebral artery is compressed?

Tortuosity of the vertebral artery and compression of the brainstem may cause blood flow insufficiency in perforating branches which may lead to transient symptoms. If the impingement is severe and does not revolve, patients may have progressive symptoms.

What is a medullary stroke?

A medullary stroke happens in the medulla oblongata, which is located on the brain stem. This part of your brain transfers messages from the brain to the spinal cord and is responsible for many of your body’s involuntary functions. A medullary stroke can cause serious symptoms like paralysis and coordination problems.

What does brainstem compression feel like?

The most common symptom associated with a Chiari malformation is occipital headaches. These headaches are felt near the base of the skull and may radiate to cause pain in the neck and shoulders. They can be severe and may be described as sharp, brief, throbbing or pulsating.

Can you live with blocked basilar artery?

The patient mortality rate is greater than 85%, although it drops to as low as 40% in patients with recanalization. One can expect good functional outcomes in as few as 24 to 35% of patients treated with intravenous or intra-arterial thrombolysis.

What are the symptoms of a compressed artery in your neck?

  • Sudden trouble seeing in one or both eyes.

Can a compressed artery cause dizziness?

Our study includes another ten patients with medullary compression by a vertebral artery. Among our reported patient, the most common clinical signs and symptoms were dizziness, vertigo, imbalance, and limb weakness. Dysarthria was also observed in two patients.

Can you live with a damaged medulla?

It plays an essential role in passing messages between your spinal cord and brain. It’s also essential for regulating your cardiovascular and respiratory systems. If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation.
