  2. Vertebral artery dissection - Wikipedia

    en.wikipedia.org/wiki/Vertebral_artery_dissection

    Vertebral artery dissection (VAD) is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. The symptoms of vertebral artery dissection include head ...

  3. Carotid artery dissection - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_dissection

    Carotid artery dissection is a serious condition in which a tear forms in one of the two main carotid arteries in the neck, allowing blood to enter the artery wall and separate its layers (*dissection*). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially ...

  4. Reversible cerebral vasoconstriction syndrome - Wikipedia

    en.wikipedia.org/wiki/Reversible_cerebral...

    Neurology. Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]

  5. Cervical artery dissection - Wikipedia

    en.wikipedia.org/wiki/Cervical_artery_dissection

    Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus ...

  6. Lateral medullary syndrome - Wikipedia

    en.wikipedia.org/wiki/Lateral_medullary_syndrome

    Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem. The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1] Lateral medullary syndrome is also called Wallenberg's ...

  7. Arterial dissections - Wikipedia

    en.wikipedia.org/wiki/Arterial_dissections

    Arterial dissections become life-threatening when growth of the false lumen prevents perfusion of the true lumen and the related end organs. For example, in an aortic dissection, if the left subclavian artery orifice were distal to the origin of the dissection, then the left subclavian would be said to be perfused by the false lumen, while the left common carotid (and its end organ, the left ...

  8. Carotid artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_stenosis

    The internal carotid artery supplies the brain. Plaque often builds up at that division and causes a narrowing (stenosis). Pieces of plaque can break off and block the small arteries above in the brain, which causes a stroke. Plaque can also build up at the origin of the carotid artery at the aorta. [citation needed]

  9. Cerebellar stroke syndrome - Wikipedia

    en.wikipedia.org/wiki/Cerebellar_stroke_syndrome

    Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery. [ 1 ] Cardinal signs include vertigo, headache, vomiting, and ataxia. [ 2 ] Left sided cerebellar stroke due to ...
