Insights
Cervical artery dissection (CAD) is a leading cause of stroke in young adults. This case highlights essential thrombocythemia (ET) as a potential contributing factor to CAD, suggesting a link between blood disorders and arterial events.
Area of Science:
- Neurology
- Vascular Medicine
- Hematology
Background:
- Cervical artery dissection (CAD) is a significant cause of ischemic stroke, particularly in younger populations.
- The precise etiology of spontaneous CAD remains incompletely understood.
- Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterized by elevated platelet counts.
Observation:
- A young woman presented with acute ischemic stroke secondary to internal carotid artery (ICA) dissection.
- This patient was concurrently diagnosed with essential thrombocythemia (ET).
Findings:
- Review of existing literature identified limited cases of comorbid CAD and ET.
- The co-occurrence suggests a potential pathophysiological link between ET and cervical artery vulnerability.
- ET may predispose individuals to cervical artery dissection through mechanisms like altered microcirculation.
Implications:
- Understanding the link between ET and CAD could refine stroke risk stratification in young adults.
- Further research into the vascular effects of ET may reveal novel insights into spontaneous arterial dissections.
- This association warrants consideration in the clinical evaluation of young stroke patients with thrombocytosis.
Abstract:
Cervical artery dissection (CAD) is an important etiology of stroke in young adults. Its etiology is incompletely understood. Here, we report a young woman who presented with acute ischemic stroke in the setting of internal carotid artery (ICA) dissection and essential thrombocythemia (ET). We present a review of previous cases with comorbidity of CAD and ET and discuss the pathophysiological implications of this co-occurrence. In particular, we speculate that ET may increase the susceptibility of cervical vessels to spontaneous dissection, for example, by disturbing the microcirculation within the vessel wall.
