  • Title: Spontaneous Subclavian Artery Dissection Causing Ischemia of the Medulla Oblongata and Cerebellum.
    Author: Nagino N, Funakoshi H, Shiga T, Saigusa K.
    Journal: J Emerg Med; 2017 Nov; 53(5):e77-e80. PubMed ID: 28987310.
    Abstract:
    BACKGROUND: Spontaneous subclavian artery dissection is a rare etiology. Spontaneous artery dissection causing brain ischemia is rare in all ischemic strokes. However, in young to middle-aged patients with brain ischemia, spontaneous carotid or vertebral artery dissection causing ischemic stroke accounts for 10-25%. CASE REPORT: A 58-year-old man with a history of hypertension presented to the Emergency Department with a sudden onset of left-arm paresthesia and numbness followed by symptoms of vertigo and vomiting. A neurological examination showed left-arm paresthesia, horizontal-rotational nystagmus, and left-side dysmetria according to a finger-to-nose test. Contrast-enhanced computed tomography showed left subclavian artery dissection. Diffusion-weighted imaging demonstrated hyperintensity in the left medulla oblongata and inferior part of the cerebellum. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous artery dissection is an important etiology of ischemic stroke among young patients. Cervical magnetic resonance angiography is the gold standard for the diagnosis of arterial dissection. Cervical disc disease is a common etiology in a patient with neck and shoulder pain without cause or neurologic symptoms, when cervical MRI is negative, however, spontaneous subclavian artery dissection should be considered in the differential diagnosis when a patient, especially in a case of younger patient, presents with acute new-onset neck and shoulder pain followed by the onset of neurological symptoms.
