Confirm that the vascular abnormality is really a dissection
A cervical artery dissection is usually diagnosed when imaging shows features such as mural haematoma, intimal flap, double lumen, tapered stenosis, occlusion or a dissecting aneurysm in the carotid or vertebral artery. CTA and MRI/MRA are commonly used; dedicated fat-suppressed or vessel-wall MRI sequences can help demonstrate intramural blood. A second opinion should review the original DICOM images because atherosclerotic stenosis, vasculitis, fibromuscular dysplasia and artefact can sometimes mimic dissection.
Headache or neck pain can precede cerebral ischaemia
Dissection can present with unilateral neck pain or headache, partial Horner syndrome, cranial-nerve symptoms, retinal ischaemia, TIA or ischaemic stroke. Some patients have only local symptoms, while others present with a large-vessel occlusion. Sudden focal weakness, speech difficulty, visual loss, severe imbalance or another acute stroke syndrome requires emergency stroke care without waiting for specialist travel arrangements.
CTA and MRI/MRA are usually sufficient; catheter angiography is selective
Non-invasive vascular imaging usually establishes the diagnosis and can show stenosis, occlusion, mural haematoma and dissecting aneurysm. Catheter digital-subtraction angiography is invasive and is generally reserved for uncertainty that would change management, complex anatomy or planning of an endovascular procedure rather than performed routinely in every stable patient.
Acute ischaemic stroke is treated according to standard eligibility
The European Stroke Organisation guideline recommends intravenous thrombolysis for otherwise eligible patients with acute ischaemic stroke due to extracranial artery dissection and supports mechanical thrombectomy for appropriate anterior-circulation large-vessel occlusion. The 2024 American Heart Association scientific statement similarly considers thrombolysis and mechanical thrombectomy reasonable when standard criteria are met. A known dissection is therefore not, by itself, a reason to withhold evidence-based acute reperfusion therapy.
Antiplatelet versus anticoagulation remains an individualized decision
ESO guidance allows either antiplatelet or anticoagulant therapy in symptomatic extracranial dissection because randomized trials did not establish a clear overall winner. A 2024 individual-patient meta-analysis of the two randomized trials likewise found no statistically significant difference in the composite of ischaemic stroke, major bleeding or death, although individual outcomes differed. A separate 2024 meta-analysis incorporating observational data suggested fewer ischaemic strokes with anticoagulation but more major bleeding. The practical conclusion is to individualize therapy according to infarct burden, intraluminal thrombus, bleeding risk, recurrent embolism, anatomy and other clinical factors rather than presenting one regimen as universally superior.
Antithrombotic therapy is commonly continued for several months
The 2024 AHA scientific statement suggests individualized antithrombotic therapy for at least three to six months. Whether treatment should continue beyond that period depends on recurrent symptoms, vascular risk, follow-up imaging, residual stenosis or aneurysmal change, bleeding risk and the original indication. Medication should not be stopped or extended solely from a generic internet timetable.
Stenting is not routine treatment for a stable cervical dissection
Most extracranial dissections are managed medically. Endovascular stenting may be considered in selected patients with significant stenosis causing haemodynamic compromise and recurrent ischaemic events despite optimal medical treatment, or as part of an acute thrombectomy strategy in specific anatomy. The decision should come from an experienced stroke and neurointerventional team because stenting introduces procedural and antiplatelet-related risks.
Follow-up imaging evaluates healing, residual stenosis and dissecting aneurysm
Vascular healing and recanalization often occur during the first months after diagnosis and can continue for up to about a year. Follow-up CTA or MRA is commonly used to document remodeling when the result will affect treatment. Cervical dissecting aneurysms frequently remain clinically benign, so their presence does not automatically mean that surgery or stenting is required.
Look for associated arteriopathy selectively
Most patients do not have a single identifiable inherited connective-tissue disorder. However, recurrent or multiple dissections, marked arterial tortuosity, fibromuscular dysplasia, aneurysms, unusual physical features or a strong family history may justify broader vascular or genetic assessment. The 2024 AHA statement also discusses screening for associated aneurysm, aortic-root disease and renal artery disease in selected contexts.
Return to sport and neck-loading activities should be individualized
Evidence that a specific activity causes recurrent dissection is limited. Because recurrence or extension risk is greatest early after diagnosis, the AHA statement considers it reasonable to avoid activities with substantial cervical injury risk for roughly one to six months and until the index dissection has healed, with longer precautions for selected high-risk patients. Decisions about contact sport, heavy lifting, extreme neck movement or manipulation should be discussed with the treating team.
Heidelberg has a dedicated rare-neurovascular focus that explicitly includes dissections
Heidelberg University Hospital's Center for Rare Neurological Diseases lists dissections of the brain-supplying vessels among its rare neurovascular treatment priorities. The center links neurology with neuroradiology and other specialist disciplines, making it relevant for complex diagnostic review, recurrent dissection and questions about underlying vascular disease.
UKE Hamburg offers a head-and-neck vascular consultation for suspected dissection and second opinions
University Medical Center Hamburg-Eppendorf's neuroradiology consultation specifically includes evaluation of suspected dissections of head and neck vessels, unclear vascular findings and second opinions on abnormal CT or MRI. UKE's neurological vascular clinic also manages difficult stroke questions and rare or complicated cerebrovascular disease, providing an appropriate multidisciplinary route for complex dissection cases.
What to send for a German cervical-dissection second opinion
The original vascular imaging and event timeline are more useful than a diagnosis label alone.
- Initial CTA or MRA DICOM files
- Brain MRI or CT showing any infarction or haemorrhage
- Dedicated vessel-wall or fat-suppressed neck MRI if performed
- Follow-up CTA/MRA demonstrating healing, persistent stenosis or dissecting aneurysm
- Hospital discharge summary and acute stroke treatment details
- Exact symptom timeline including head/neck pain, Horner syndrome, TIA or stroke
- Current and previous antiplatelet or anticoagulant medication with doses
- Thrombectomy, stenting or other procedure reports if performed
- History of previous dissections, aneurysms or fibromuscular dysplasia
- Relevant family history or connective-tissue/genetic assessment
- Exact question: confirm dissection, choose antithrombotic strategy, review treatment duration, interpret follow-up imaging, assess recurrence risk or evaluate stenting
New stroke symptoms are an emergency
New weakness, facial droop, speech difficulty, visual loss, severe imbalance, reduced consciousness or another sudden focal neurological deficit require immediate local emergency stroke assessment. Planned international second opinion should only follow stabilization of the acute event.
