Cervical artery dissection is a tear or separation within the wall of one of the major arteries supplying blood to the brain. It most commonly affects the internal carotid artery or vertebral artery in the neck. Blood can enter the artery wall and form an intramural haematoma, meaning a collection of blood within the layers of the vessel wall. This may narrow or block the artery, encourage formation of a blood clot, or occasionally produce an outpouching known as a dissecting aneurysm.
Cervical artery dissection is an important cause of stroke, particularly in younger and middle-aged adults. It can occur spontaneously, after relatively minor neck trauma or movement, or following significant trauma. In many cases there is no single identifiable cause.
Symptoms can initially resemble a musculoskeletal neck problem. New or unusual neck pain and headache are common, sometimes occurring before neurological symptoms develop. This makes cervical artery dissection particularly important for physiotherapists assessing people with neck pain, headache or dizziness.
Physiotherapy for cervical artery dissection is very different from routine physiotherapy for mechanical neck pain. An active or suspected dissection requires urgent medical assessment rather than neck treatment. Once the condition is medically stable, physiotherapy may become important for neurological rehabilitation, restoring mobility and physical conditioning, managing secondary musculoskeletal problems and supporting a safe return to normal activities.
A person with sudden unusual neck or head pain accompanied by symptoms such as facial drooping, weakness, numbness, difficulty speaking, visual disturbance, severe dizziness, loss of coordination or difficulty walking requires emergency medical assessment.
Key Facts
- Cervical artery dissection is rare, affecting about 3 people per 100,000 each year. 🔗
- Neck pain or headache is very common, with one study finding it in about 8 out of 10 people with spontaneous cervical artery dissection. 🔗
- Cervical artery dissection causes up to 15% to 25% of ischaemic strokes in people under 50. 🔗
- Cervical artery dissection has a recurrence rate of around 4% overall. 🔗
Risk Factors
- Recent minor neck trauma, sporting collision, motor vehicle accident, sudden rotation, or sudden extension movement
- Recent infection, coughing, sneezing, vomiting, or other episodes that increase strain through the neck and vascular system
- Migraine history, which has been associated with cervical artery dissection in research
- Connective tissue disorders or inherited collagen conditions that may affect artery wall strength
- Fibromuscular dysplasia or other vascular wall abnormalities
- High blood pressure or other cardiovascular risk factors that may increase stress on blood vessel walls
- Family history of arterial dissection or vascular fragility
- Activities involving repeated or forceful end-range neck movements, especially if combined with other risk factors
Symptoms
- Sudden or unusual neck pain, often felt high in the neck or at the base of the skull
- New headache, especially one that feels different from the person’s usual headache pattern
- One-sided facial, jaw, temple, eye, or ear pain, more common with carotid artery involvement
- Occipital headache, upper neck pain, dizziness, nausea, or imbalance, more common with vertebral artery involvement
- Visual changes, double vision, blurred vision, drooping eyelid, or a smaller pupil on one side
- Speech changes, swallowing difficulty, facial droop, limb weakness, numbness, clumsiness, or walking difficulty
- Pulsatile tinnitus, described as hearing a heartbeat or whooshing sound in the ear
- Vertigo, unsteadiness, loss of coordination, or a feeling of being pulled to one side
- Symptoms that feel unlike a normal neck strain, especially when pain is severe, sudden, or associated with neurological signs
Aggravating Factors
- Sudden neck rotation, extension, or combined twisting and looking up, particularly in the early or medically unstable stage
- High-velocity neck manipulation or forceful end-range manual techniques, which are not appropriate when cervical artery dissection is suspected or confirmed
- Heavy lifting, straining, breath-holding, or high-intensity exercise before medical clearance
- Contact sport, collision sport, wrestling, or activities with risk of head or neck impact during the healing period
- Prolonged positions that reproduce dizziness, visual symptoms, nausea, neurological symptoms, or unusual head and neck pain
- Returning too quickly to running, gym training, swimming, cycling, or overhead sport without a staged cervical artery dissection rehab plan
Causes
Cervical artery dissection may occur spontaneously or following an identifiable event. Potential causes or triggers include:
- Head or neck trauma: Motor vehicle accidents, falls and sporting collisions can injure the wall of the carotid or vertebral arteries.
- Sudden or forceful neck movement: Rapid or extreme neck movements have been reported before some dissections, although this does not necessarily mean the movement was the direct cause.
- Heavy lifting or straining: Activities that involve substantial physical effort or straining have occasionally been associated with the onset of cervical artery dissection.
- Coughing, sneezing or vomiting: Forceful coughing, sneezing or vomiting may precede a dissection in some people.
- Sport and physical activity: Contact sports and activities involving substantial or repeated neck movement may sometimes occur shortly before symptoms develop.
- No obvious trigger: Many cervical artery dissections are considered spontaneous because no specific injury or triggering event can be identified.
Some people may also have underlying factors that make their artery walls more susceptible to dissection. These can include connective tissue disorders, fibromuscular dysplasia and other vascular abnormalities. Migraine, high blood pressure and recent infection have also been associated with cervical artery dissection.
Importantly, having one of these risk factors or performing one of the activities listed above does not mean that a person will develop a cervical artery dissection.
For physiotherapists, the key clinical issue is recognising when pain does not behave like a typical muscle, joint, disc, or nerve problem. A sudden severe headache, unusual neck pain, neurological symptoms, visual symptoms, faintness, drop attacks, new imbalance, or symptoms that are difficult to reproduce mechanically should prompt urgent medical referral rather than routine neck treatment. Physiotherapy for cervical artery dissection begins with safe screening and appropriate escalation.
How Is It Diagnosed?
Cervical artery dissection cannot be reliably diagnosed or ruled out through a routine musculoskeletal examination alone. Diagnosis generally involves a combination of clinical assessment and vascular imaging.
- Medical history: A doctor will ask about the onset of neck pain or headache, neurological symptoms, recent trauma, unusual neck movements, physical activity and relevant medical or vascular conditions.
- Pain characteristics: Particular attention is given to new, sudden or unusual neck pain or headache, especially when the symptoms feel different from previous episodes.
- Neurological examination: Strength, sensation, reflexes, coordination, balance, walking, speech and other neurological functions may be assessed to identify signs of reduced blood flow to the brain or stroke.
- Cranial nerve examination: Eye movements, facial movement, swallowing and other cranial nerve functions may be checked. Findings such as a drooping eyelid or unequal pupils can provide important diagnostic clues.
- Vascular imaging: Computed tomography angiography or magnetic resonance angiography is commonly used to examine the carotid and vertebral arteries and confirm a suspected cervical artery dissection.
- Brain imaging: Computed tomography or magnetic resonance imaging of the brain may be performed if a transient ischaemic attack or stroke is suspected.
- Physiotherapy screening: A physiotherapist may recognise signs and symptoms that raise suspicion of cervical artery dissection, but cannot confirm the diagnosis through physical testing. If the presentation suggests possible vascular involvement, routine neck treatment should be deferred and urgent medical assessment arranged.
- Emergency assessment: New neurological symptoms, sudden severe or unusual headache or neck pain, visual disturbance, difficulty speaking, weakness, numbness, severe dizziness or loss of coordination require urgent medical assessment.
Investigations & Imaging
- CT angiography
- Often used urgently to visualise the carotid and vertebral arteries. It can show narrowing, blockage, irregular artery shape, a flap, pseudoaneurysm, or reduced blood flow linked with cervical artery dissection.
- Magnetic resonance angiography
- Shows the blood vessels in the neck and head without ionising radiation. It may help identify vessel narrowing, occlusion, or changes in blood flow, and can be combined with MRI brain imaging.
- MRI brain and neck
- Can detect stroke, small areas of brain injury, and signs of blood within the wall of the dissected artery. It is useful when neurological symptoms are present or when symptoms have evolved over time.
- Doppler ultrasound
- May assess blood flow in accessible parts of the carotid or vertebral arteries. It is less complete than CT angiography or magnetic resonance angiography for some upper neck dissections, so it is not always sufficient on its own.
- Catheter angiography
- An invasive test that may be used when the diagnosis remains uncertain or when endovascular treatment is being considered. It provides detailed images of the artery lumen but is not usually the first investigation for every person.
Grading / Classification
- Carotid artery dissection
- Involves the internal carotid artery. Symptoms may include one-sided headache, facial pain, temple pain, eye pain, jaw pain, pulsatile tinnitus, Horner’s syndrome, transient ischaemic attack, or stroke symptoms.
- Vertebral artery dissection
- Involves the vertebral artery, commonly associated with upper neck pain, occipital headache, dizziness, nausea, unsteadiness, double vision, swallowing difficulty, coordination problems, or posterior circulation stroke symptoms.
- Extracranial dissection
- Occurs in the part of the artery outside the skull. This is the form most often discussed in relation to neck pain, manual therapy screening, and cervical artery dissection physiotherapy safety.
- Intracranial extension
- Involves the portion of the artery inside the skull or extension towards it. This may carry different risks and requires specialist medical management.
- Dissection with local symptoms only
- Pain, headache, Horner’s syndrome, or tinnitus may occur without stroke. Physiotherapy still requires medical clearance because symptoms can change.
- Dissection with transient ischaemic attack or stroke
- Neurological symptoms occur because of reduced blood flow or clot-related ischaemia. Cervical artery dissection rehab may then include stroke physiotherapy, balance retraining, gait rehabilitation, upper limb rehabilitation, and graded conditioning.
Physiotherapy Management
Physiotherapy for cervical artery dissection depends on the stage of recovery, whether a stroke has occurred, current symptoms and medical advice. Physiotherapy does not heal the damaged artery itself. During the acute stage, medical management takes priority.
Once the person is medically stable, physiotherapy can help restore movement, strength, balance, walking ability, cardiovascular fitness and confidence with everyday activities. Cervical artery dissection rehab should be individualised and progressed gradually.
Exercise
Cervical artery dissection physiotherapy exercises should be introduced gradually and according to medical clearance.
- Begin with gentle, low-intensity physical activity where appropriate.
- Gradually rebuild walking tolerance and cardiovascular fitness.
- Progress upper and lower-limb strengthening according to symptoms and medical restrictions.
- Use functional exercises such as sit-to-stand, step-ups and walking where appropriate.
- If a stroke has occurred, exercises may target weakness, balance, coordination, walking and reduced endurance.
- Progress towards work, recreational and sport-specific exercise as recovery allows.
- Avoid an immediate return to heavy lifting, intense straining or high-intensity exercise during early recovery.
For active people and athletes, physiotherapy may progress from walking and low-intensity aerobic exercise through to strengthening, running, agility, sport-specific drills and eventually normal training. Contact sports, heavy resistance training and activities involving substantial neck forces require additional consideration and appropriate medical clearance.
Activity Modification
Temporary activity modification can reduce unnecessary stress on the neck and cardiovascular system during early recovery.
Depending on medical advice, activities that may initially need to be modified include:
- Heavy lifting and strenuous resistance training
- High-intensity exercise
- Activities involving repeated or extreme neck rotation or extension
- Contact or collision sports
- Activities with a significant risk of falls, head impact or neck trauma
- Exercises involving substantial straining
These restrictions are not necessarily permanent. A physiotherapist can help progressively reintroduce normal activities as the condition stabilises and medical restrictions are lifted.
Postural Retraining
Poor posture should not be presented as a cause of cervical artery dissection. However, reduced activity, protective muscle guarding and fear of neck movement can contribute to stiffness or discomfort during recovery.
Physiotherapy may help with:
- Gradually restoring comfortable neck movement
- Reducing unnecessary guarding and stiffness
- Increasing tolerance to sitting and desk work
- Improving tolerance to sustained working positions
- Returning to driving when medically appropriate
- Encouraging regular changes of position rather than maintaining a rigid or supposedly “perfect” posture
Education
Education is an important part of physiotherapy for cervical artery dissection, particularly because people may become understandably concerned about moving their neck or returning to exercise.
A physiotherapist can help by:
- Explaining which activities may need to be temporarily restricted
- Identifying activities that can be safely continued
- Providing a structured cervical artery dissection rehab programme
- Teaching how to gradually increase exercise and physical activity
- Reducing unnecessary fear and avoidance of normal movement
- Planning a graded return to work, recreation and sport
- Explaining the importance of following medication and medical recommendations
- Helping patients recognise symptoms that require urgent reassessment
Patients should seek urgent medical attention for new neurological symptoms such as facial drooping, weakness or numbness, speech difficulty, significant visual disturbance, severe dizziness or imbalance, new difficulty walking, or a sudden severe or distinctly unusual headache or neck pain.
Other
If cervical artery dissection results in a stroke, neurological rehabilitation may become a major component of physiotherapy.
Depending on the person’s impairments, physiotherapy may include:
- Walking and gait retraining
- Balance and coordination exercises
- Transfer practice
- Upper and lower-limb strengthening
- Falls prevention strategies
- Progressive walking programmes
- Functional task practice
- Cardiovascular conditioning
- Rehabilitation of dizziness or balance problems where appropriate
Ongoing monitoring is also important throughout cervical artery dissection rehab. New neurological symptoms or a significant change in headache or neck pain during rehabilitation should result in exercise being stopped and urgent medical assessment being considered.
Other Treatments
Other treatments are guided by medical specialists. Antiplatelet medication, such as aspirin, or anticoagulation medication may be used to reduce the risk of clot-related complications. The specific medication, dose, and duration should always be directed by a doctor.
Blood pressure management may be important, especially if high blood pressure is present. People may also receive treatment for migraine, pain, nausea, dizziness, or stroke-related complications. If swallowing, speech, cognition, or vision are affected, a multidisciplinary rehabilitation team may be involved.
Psychological support can also be valuable. Cervical artery dissection can be frightening, particularly for active people who were previously healthy. Anxiety about stroke risk, neck movement, exercise, driving, work, or parenting tasks is common. Physiotherapy can support confidence through education and graded exposure, while psychology or counselling may help with ongoing fear, sleep disruption, or trauma-related stress.
Surgery
Most cervical artery dissections are managed medically rather than surgically. Medical care may involve antiplatelet or anticoagulant medication, monitoring, stroke management, and follow-up imaging. The choice of medication is made by the treating medical team based on artery findings, symptoms, bleeding risk, stroke risk, and individual health factors.
Surgical or endovascular procedures are not routine for every person with cervical artery dissection. They may be considered in selected cases, such as ongoing or recurrent ischaemic symptoms despite medical treatment, severe narrowing with compromised blood flow, an enlarging pseudoaneurysm, or complex arterial injury. Options may include stenting, endovascular repair, or other specialist vascular procedures.
Physiotherapy after surgery or endovascular treatment depends on the person’s neurological status, access-site precautions, medical restrictions, and overall function. The physiotherapist may assist with mobility, balance, graded exercise, stroke rehabilitation, neck and shoulder comfort, and return-to-work or return-to-sport planning once cleared.
Prognosis & Return to Activity
Prognosis after cervical artery dissection varies depending on whether the dissection caused no neurological injury, a transient ischaemic attack or a stroke. Many people recover well, although recovery may take longer if a stroke has caused ongoing weakness, dizziness, balance problems, fatigue or visual symptoms.
Return to activity should be gradual and guided by the medical team and physiotherapist. During early recovery, people may be advised to temporarily avoid:
- Contact or collision sports
- Heavy lifting and maximal-effort exercise
- High-intensity exercise
- Forceful or extreme neck movements
- Activities with a significant risk of head or neck trauma
Cervical artery dissection rehab is usually progressed in stages rather than according to a single fixed return date. Depending on the individual, physiotherapy may progress through:
- Gentle walking and normal daily activities
- Light aerobic exercise
- Controlled strengthening
- Balance and coordination exercises where required
- Moderate-intensity cardiovascular exercise
- Work-specific or gym-based exercises
- Sport-specific training
- Gradual return to unrestricted activity following appropriate medical clearance
For people returning to the gym, a physiotherapist may initially modify heavy compound lifts, breath-holding and straining, maximal-effort sets and exercises that place the neck under substantial load.
For athletes, return to sport depends on the type of activity, risk of collision or falls, neck movement demands, exercise intensity, neurological recovery and medical advice.
Some people continue to experience headache, neck discomfort, dizziness or fatigue during recovery. These symptoms do not necessarily mean that the artery is worsening. However, new or worsening neurological symptoms, such as weakness, numbness, speech difficulty, visual disturbance, severe imbalance or loss of coordination, require urgent medical assessment.
Physiotherapy for cervical artery dissection can help patients safely rebuild strength, balance, fitness and confidence while progressing towards their usual work, exercise and sporting activities.
Complications
- Transient ischaemic attack, where temporary neurological symptoms occur due to reduced blood flow or clot movement
- Ischaemic stroke, which may affect movement, speech, swallowing, sensation, coordination, vision, balance, or cognition
- Artery narrowing or occlusion, where blood flow through the affected vessel is reduced or blocked
- Pseudoaneurysm, where the artery wall balloons outward at the site of injury
- Persistent headache, neck pain, dizziness, tinnitus, or visual symptoms
- Horner’s syndrome, involving drooping eyelid, smaller pupil, or altered facial sweating on one side
- Reduced confidence with neck movement, exercise, driving, work, or sport
- Physical deconditioning due to prolonged avoidance of activity after diagnosis
Preventing Recurrence
- Avoid high-velocity cervical manipulation or forceful end-range neck techniques if there is a history of cervical artery dissection unless a specialist medical team has clearly advised that cervical manual therapy is safe.
- Build back into exercise gradually after medical clearance, avoiding sudden spikes in intensity, heavy straining, and breath-holding that may increase vascular load.
- Modify activities that combine loaded neck rotation and extension, such as awkward overhead work, certain yoga positions, wrestling positions, or heavy lifting with the head turned.
- Use sport-specific return-to-play planning after cervical artery dissection, especially for contact sport, combat sport, gymnastics, cycling, swimming, and overhead sport.
- Manage blood pressure and cardiovascular risk factors with medical guidance, as vascular health is relevant to reducing future arterial stress.
- Warm up before training and avoid sudden maximal efforts when returning to gym, running, cycling, or field sport after a period of restricted activity.
- Seek early assessment for unusual new headache or neck pain, especially if it is sudden, one-sided, severe, or linked with dizziness, visual symptoms, speech changes, weakness, numbness, or imbalance.
- Work with a physiotherapist to restore comfortable neck, shoulder, and thoracic mobility so protective stiffness does not lead to compensatory overload or fear-based movement patterns.
When to See a Physio
- After medical diagnosis and clearance, to plan safe cervical artery dissection rehab and graded return to daily activity
- After a transient ischaemic attack or stroke related to cervical artery dissection, for neurological physiotherapy, balance retraining, walking rehab, and strengthening
- If ongoing neck stiffness, headache-related muscle guarding, shoulder tension, or fear of neck movement is limiting normal function
- Before returning to gym, running, cycling, swimming, contact sport, manual work, or heavy lifting
- If dizziness, imbalance, fatigue, or reduced confidence persists after the acute medical phase
- If you need help modifying work posture, driving tolerance, sleep positions, or home tasks during recovery
- Urgently seek medical care, not routine physiotherapy, if symptoms include sudden severe headache, new neurological symptoms, facial droop, speech changes, swallowing difficulty, visual changes, fainting, new limb weakness, numbness, or severe unusual neck pain
