How is arterial dissection diagnosed?
How is arterial dissection diagnosed?
Diagnosis. Typically, a magnetic resonance imaging (MRI) and MR Angiogram are done to look at the brain and the blood vessels of the head and neck and visualize a tear within the wall of an artery.
How is vertebral artery dissection diagnosed?
Computed tomography (CT) scanning – Identifies subarachnoid hemorrhage ; CT angiography (CTA), along with magnetic resonance angiography (MRA), are the imaging modalities of choice for vertebral artery dissections; however, CTA is less accurate in the presence of calcified arteries.
How is carotid artery dissection diagnosed?
How is carotid dissection diagnosed?
- MRI of the brain and neck.
- Magnetic resonance angiography (MRA) of the brain and neck.
- Cranial CT.
- Cranial computed tomography angiography (CTA)
- Carotid Doppler and ultrasound.
How serious is a cerebral artery dissection?
A diagnosis of cerebral arterial dissection is clinically significant because it can cause severely disabling ischemic stroke or subarachnoid hemorrhage (SAH) requiring specific management according to the vessel status demonstrated on cerebral angiography.
How do you fix an artery dissection?
If SCAD has blocked blood flow to your heart or if medications don’t control your chest pain, your health care provider might recommend placing a tiny mesh tube (stent) inside your artery to hold it open. A stent can help restore blood flow to your heart.

How long does it take for a dissected artery to heal?
Once diagnosed and treated, patients with carotid artery dissection require regular follow-up and imaging studies of both carotid arteries. Healing usually takes 3-6 months, and the incidence of contralateral dissection is higher in these patients than in the general population.
What is the prognosis for arterial dissection?
Once imaging has made the diagnosis, the treatment depends on patient symptoms. For those patients that survive the initial dissection, the prognosis is usually good. Approximately 10% of patients die initially. In one clinical follow-up study, 80% achieved a full recovery.
