Thyrotoxicosis and bilateral internal carotid artery dissections
Cervical artery dissection is a rare but important diagnosis to consider in young patients presenting with stroke. Multiple etiologies of cervical artery dissections have been previously reported, but the association with thyrotoxicosis is extremely rare. A previously healthy 43-year-old female presented to the emergency department with new symptoms related to thyrotoxicosis and bilateral internal carotid artery dissections. Her atrial fibrillation and hypertension resolved by treating the underlying hyperthyroidism with methimazole and propranolol.

He also had had chemotherapy and radiation for anal cancer. The patient said the pain had started 45 minutes earlier when he was sitting on the toilet.He described the pain as sore in quality and 10/10 on the pain scale. He reported that it had started in his lower back and radiated to his left leg. He said he had had no trauma or weakness to the regi...

Vertebral Artery Dissection Masquerading as Concussion in an Adolescent
Conclusions Detailed history and thorough neurological examination in conjunction with appropriate imaging are necessary to distinguish between brainstem/cerebellar ischemia from vertebral artery dissection and concussion.

Extracranial Cervical Artery Dissections
Cervical artery dissections (CeAD) include both internal carotid and vertebral artery dissections. They are rare but important causes of stroke, especially in younger patients. CeAD should be considered in patients with strokelike symptoms, a new-onset headache and/or neck pain, and/or other risk factors. Early imaging with computed tomography (CT) or magnetic resonance imaging (MRI) is key to making the diagnosis. Treatment may vary depending on the extent of the dissection, timing of the dissection, and other comorbidities. The overall prognosis is good, but does depend on the initial severity of symptoms.

The Use of Tissue Plasminogen Activator in the Treatment of Wallenberg Syndrome Caused by Vertebral Artery Dissection
Acute cerebrovascular accident (CVA) is a devastating cause of patient morbidity and mortality. Up to 10% of acute CVAs in young patients are caused by dissection of the vertebral or carotid artery. Wallenberg syndrome results from a CVA in the vertebral or posterior inferior artery of the cerebellum and manifests as various degrees of cerebellar dysfunction. The administration of a thrombolytic medication has been recommended in the treatment of patients with stroke caused by cervical artery dissection.

Cervical Artery Dissections: A Review
Cervical artery dissection (CeAD) is an infrequent, yet potentially devastating, cause of stroke. While uncommon, CeAD is important for emergency physicians to quickly diagnose and treat because of the potential for cerebral ischemia, stroke, blindness, or death. To our knowledge, no review articles in the emergency medicine literature have been published on CeAD. A literature search of MEDLINE/PubMed, Embase, and other major abstracts in the English language was performed for the following terms: cervical artery, vertebral artery, and carotid artery dissection.

The Case Files: Traumatic Carotid Dissection
By Hsiao, Jonie MD   A 30-year-old man who was right-hand dominant presented 10 days after sustaining left-sided face and head trauma from a fall from a skateboard at an unknown speed. He lost consciousness for several seconds, and initially developed a headache with nausea and vomiting. A non-contrast head CT performed at another hospital done two days after the incident was reportedly negative.   He now presents primarily with concerns about the appearance of his left eye. He has notable anisocoria and a droopy eyelid. His left pupil is notably smaller, 2 mm, compared with the right eye, 5 mm. Both are reactive. The re...

Acute neurology in the emergency department
A 66-year-old woman presented with sudden onset tearing interscapular pain 1 h after gentle neck exercises. Over the next 3 h, she developed flaccid left arm and leg paralysis and a left Horner's syndrome. Her initial CT scan revealed no evidence of cerebral ischaemia or aortic/carotid dissection but did reveal what was thought to be a calcified arteriovenous malformation in the right frontal lobe. Thrombolysis for a presumed acute stroke was considered but not initiated. By 5 h, the patient had lost light touch sensation and proprioception of her left side, and additionally she developed grade 3/5 right-sid...
