124) described a prevalence of 12% of cranial nerve palsies in their study of 190 adult patients with spontaneous extracranial internal carotid artery dissection. Cervical artery dissections is the collective term for dissections of the carotid or vertebral arteries. The classic symptoms and signs of carotid artery dissection include the following: • … Key Words: carotid artery diagnostic methods ultrasound M ost patients with spontaneous dissection of the internal carotid artery (sICAD) come to clinical attention after stroke and other ischemic events.1,2 However, about 20% of patients with sICAD experience only local symptoms (head or neck pain, pulsatile tinnitus), local signs (Horner syn- The most commonly found damage to the hypoglossal nerve is observed in 5% of patients. Headache with pain in the neck and face, or symptoms similar to those of a migrainePulsatile tinnitus, or hearing one's own heartbeat Or it may occur suddenly with no known cause. A carotid dissection is a tear in the inner layer of the wall of a carotid artery that allows bleeding into the artery wall. CeAD events were classified based on 1) dissection site (internal carotid artery (ICA), vertebral artery (VA), or both); 2) clinical presentations (ischemia (TIA or ischemic stroke with or without local symptoms), local signs only (Horner syndrome, cervical pain, headache, tinnitus, caudal Diagnosis and Treatment. Dissection may occur at any age but is a common cause of stroke in young patients 3,6. In multiple case reports and small series, dissections with or without a pseudoaneurysm have been treated by observation, anticoagulation therapy, surgical reconstruction, or … Arnold M, Baumgartner RW, Stapf C, et al. Symptoms The most common symptom is headache on the same side as the dissection, usually around the eyes. The recognition of an arterial dissection requires a high degree of clinical suspicion and an ability to recognize some key neurological signs which help to key in on the diagnosis. vertebral artery dissections are uncommon. 2 Oculosympathetic paresis (also referred to as a partial Horner syndrome) is defined as ptosis and miosis without anhidrosis. The risk of ischemic stroke is increased. Carotid artery dissection is a well-known cause of ischemic stroke among young and middle-aged individuals. A bruit is sometimes heard over the neck as part of a routine physical examination. The risk of ischemic stroke is increased. The headache caused by dissection has no specific features and can resemble migraine or cluster headaches.16 Common headache characteristics include sudden onset, unilateral, constant, and … The origin of the right internal carotid artery was patent but the Doppler waveform was severely damped with the typical “bidirectional” signal associated with distal occlusive disease and commonly seen in dissections. It was the work of Fisher et al in the late 1970s that led to the recognition of the clinical and radiological features of dissection syndromes facilitating their antemortem diagnosis. In this paper, 24 cases of traumatic carotid artery dissection are described. Vascular risk factors, presenting local (headache, neck pain, Horner syndrome, pulsatile tinnitus, cranial nerve palsy on the side of the ICAD) and ischemic signs and symptoms, and ultrasonographic findings in the carotid and basal cerebral arteries were evaluated. Abstract Two cases are reported in which the diagnosis of a serious condition was delayed as the symptoms had been attributed to migraine. Objective: To study whether spontaneous dissections of the cervical internal carotid artery dissection (ICAD) with and without ischemia of the brain or retina differ in the prevalence of vascular risk factors, local neurologic signs and symptoms, and stenoses and occlusions of the cerebral arteries. Arnold M, Baumgartner RW, Stapf C, et al. A carotid dissection is a tear in the inner layer of the wall of a carotid artery that allows bleeding into the artery wall. 8 Although the pathogenesis of carotid dissections remains unknown, numerous risk factors have been postulated such as connective tissue disorders, infection, neck trauma, common neck movements, and atherosclerosis. Although uncommon in the general population, spontaneous carotid artery dissection (SCAD) is a common cause of ischaemic stroke in patients <50 years old, accounting for 14–20% of cases. eral carotid artery stenting.Her paraparesis com-pletely improved two months after the spinal cord injury. assessment of medical history, medical and neurological examination, routine blood sampling, 12-lead ECG, CDS of the cerebral arteries, and brain computed tomography in case of For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes). Early diagnosis and successful management of traumatic carotid artery dissections require a high index of clinical suspicion. Brainstem infarcts, tumors, or demyelinating disease are evaluated using MRI. Your doctor is likely to start with a thorough medical history and physical examination. dissection, fibromuscular dysplasia and extreme atherosclerosis, a CT scan (figure 1C) is needed to confirm the existence of a small carotid canal.6 To distinguish ICA aplasia from agenesis, a skull base examination for the presence of the carotid canal is needed, as the presence of the ICA (or its primor- Carotid dissection is about 3 times commoner than vertebral. Carotid artery disease consultation. Carotid/vertebral artery dissection is an underdiagnosed disease that can result in substantial morbidity. Helical computed tomography angiography is the first choice for patients who suffer a trauma. While affecting only 8% of patients, the triad of headache, ipsilateral oculosympathetic paresis, and contralateral stroke symptoms is very concerning for carotid artery dissection. A 58-year-old male patient presents with sudden, tearing retrosternal pain. Treatment Carotid and vertebral artery dissection may be treated with heparin, a medication that prevents the extension of the blood clot in the area of the dissection. Spontaneous dissection of the carotid and vertebral arteries. The dissection can propagate to the aortic valve causing aortic regurgitation, or blood may enter the pericardial space causing cardiac tamponade. Gold standard = carotid endarterectomy Carotid bypass (in the case of CCA stenosis/dissection): Bypass: subclavian to carotid for CCA occlusion Could do x-over CCA from one side to the other if there is a subclavian stenosis/dissection This case report serves to remind us to consider the diagnosis of internal carotid artery dissection in patients presenting with isolated hypoglossal nerve palsy. Vertebral Artery Dissection, CTA. 1 SCAD was first reported in 1959. The key to diagnosing a carotid dissection is imaging. Dissection may be precipitated by any accidental neck trauma or cervical manipulation. Presenting signs and symptoms include Horner's syndrome, dysphasia, hemiparesis, obtundation, and monoparesis. Ipsilateral facial or orbital pain is present in about 50% of cases(5) 1… The following imaging techniques have been found to be very helpful in properly diagnosing this condition. A carotid artery dissection can have a variety of possible causes, from apparently minor events such as coughing or sneezing to major trauma such as sports injuries or rigorous gymnastics. Newly diagnosed Horner syndrome always warrants imaging. Dissection of carotid artery. Gold standard = carotid endarterectomy Carotid bypass (in the case of CCA stenosis/dissection): Bypass: subclavian to carotid for CCA occlusion Could do x-over CCA from one side to the other if there is a subclavian stenosis/dissection Dissection of the craniocervical arteries (i.e., the carotid and vertebral arteries), which was once considered an uncommon diagnosis, has become increasingly recognized as a cause of stroke in young and middle-aged individuals. In this paper, 24 cases of traumatic carotid artery dissection are described. Sudden head, face or neck pain with neurologic symptoms, such as a small pupil on one side or a drooping eyelid (Horner's syndrome) If you suspect that you may be having a stroke, please go immediately to the nearest Emergency Room. Alerts and Notices Synopsis Carotid artery dissection is tearing of the carotid artery wall between the intimal and medial layers, resulting in an abnormal collection of blood or intramural hematoma. Or it may occur suddenly with no known cause. They may include: Headache Scalp pain Eye pain Neck pain One eye with a droopy lid and small pupil (partial Horner syndrome) Weakness or numbness on one side of your body Having trouble understanding speech or speaking Pulsing sound in an ear Trouble swallowing Abnormal or … [1] US may be more than 90% sensitive in the diagnosis of carotid dissection, thus being a reliable technique to exclude the presence of this entity. N Engl J Med. Medical imaging tests can help rule out other conditions with similar symptoms. The most common symptoms of dissection of the carotid artery are ipsilateral cervical pain, which occurs in one-quarter of patients, and headache, which occurs in two-thirds of patients. We generally use these approaches to identify a possible carotid artery dissection: 21) Provenzale J, Sarikaya B. The imaging modality of choice depends on the suspected etiology. A carotid dissection is a tear in the inner layer of the wall of a carotid artery that allows bleeding into the artery wall. Yet, carotid dissection is a main cause for strokes in young population, hence the importance of a timely diagnosis in order to minimize complications. The prognosis is felt to be good with a very low rate of recurrence. May compromise the arterial blood flow, causing ischemic stroke. If internal carotid artery dissection is included in the differential diagnosis, the possibility should be pursued until it is clinically ruled out. Extracranial carotid and vertebral artery dissection: a … Carotid artery dissection begins as a tear in one of the carotid arteries of the neck, which allows blood under arterial pressure to enter the wall of the artery and split its layers. Other symptoms include severe pain over the carotid artery in the neck, drooping eyelid, small pupils and bruits, or blood flow murmurs audible to the patient. Medical imaging tests can help rule out other conditions with similar symptoms. Introduction Carotid artery dissection (CAD) is rare, oc-curring spontaneously or secondary to trauma.
