Summary
Cervical artery dissection (CAD) affects young adults, often causing stroke. Diagnosis uses advanced imaging, and while treatment varies, outcomes are generally good.
Area of Science:
- Neurology
- Vascular Medicine
- Radiology
Background:
- Cervical artery dissection (CAD) is a significant cause of stroke in individuals under 45.
- The actual incidence of CAD may be higher than reported due to asymptomatic or mildly symptomatic cases.
- Internal carotid artery (ICA) dissections are more common than vertebral artery (VA) dissections, and extracranial dissections are more frequent than intracranial ones.
Purpose of the Study:
- To review the incidence, pathogenesis, clinical presentation, diagnostic methods, and management of cervical artery dissection.
- To highlight the role of modern diagnostic tools in identifying CAD.
- To discuss the generally favorable prognosis and common treatment strategies for CAD.
Main Methods:
- Literature review of cervical artery dissection (CAD).
- Analysis of diagnostic advancements in neuroradiology (CT, MRI, MRA) and neurosonology (TCD).
- Summary of clinical manifestations and therapeutic approaches.
Main Results:
- CAD is a leading cause of stroke in young adults, with an estimated incidence of 2.5-3 per 100,000 annually.
- Clinical signs include local symptoms (headache) and ischemic events (stroke, TIA).
- Non-invasive imaging techniques significantly improve CAD diagnosis and monitoring.
Conclusions:
- Cervical artery dissection (CAD) is an important cause of stroke in younger populations.
- Early diagnosis through advanced imaging is crucial for effective management.
- While treatment protocols lack randomized trial evidence, anticoagulation is a common approach with generally good outcomes.
