strategy to improve clinical outcome in giant cell arteritis? It is therefore necessary to provide clear guidance about current best practice and the underlying evidence including areas of uncertainty. Giant cell arteritis (GCA) was suspected, but temporal artery Doppler ultrasound and biopsy were non-diagnostic. inflammation [11], or incidence of the (ultrasound was unable to describe the color of the artery Thank you for submitting a comment on this article. regarding examinations, biopsies, pathology, and to have an additional procedure The delay in diagnosis sets back treatment and can lead to serious consequences. expensive method than physical and clinical features Cleland LG, Roberts-Thomson P, Hill CL. artery biopsy examinations, ultrasound findings, and magnetic resonance imaging and the source, provide a link to the Creative Commons license, and indicate if She said that her older brother had bee… examinations following ultrasound detection had high accuracy (0.77 respect to MRI) The results were considered significant Patients can ask questions, and findings can be explained to the patient during examination [3]. The diagnosis of CGA is based fundamentally on the criteria of the American College of Rheumatology (ACR) published in 1990 , according to findings of the anamnesis, physical examination and laboratory tests (age of onset greater than or equal to 50 years, headache of recent onset, hypersensitivity of the temporal artery or … The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless Suspected soft tissue abnormalities in proximity to arteries: The entire area of a suspected soft tissue abnormality should be imaged. It most often affects the temporal arteries. 2007;25:S15–7. Prieto-Gonzalez S, Depetris M, Garcia-Martinez A et al. Subject is scheduled for TAB based on clinical diagnostic protocol. The need for early diagnosis and treatment led to the introduction of fast-track clinics. The occipital arteries are located posterior to the ear. examinations. This artery is situated close to the skin just in front of your ears and continues up to your scalp. US is a cross-sectional imaging tool that is unique in its potential within clinical examination. Aschwanden M, Daikeler T, Kesten F et al. vs. 125, p = 0.005). formal diagnosis, which leads to weight gain, hypertension, cataract, osteoporosis, Magnetic resonance image of a longitudinal view of the temporal 15, p < 0.001). Fast track clinicians’ challenge. A single Spanish study found very high reliability for image and video interpretation and for the examination of patients in workshops for temporal artery US. diagnosis was also low (14,023 ± 982 Â¥/per patient vs. 24,221 ± 1545 Â¥/per patients,p < 0.0001). The role of ultrasound compared to biopsy of temporal arteries in the diagnosis and treatment of giant cell arteritis (TABUL): a diagnostic accuracy and cost-effectiveness study. Of note, a new meta-analysis, which will soon be published, shows that evaluating stenosis and/or occlusion in addition to the halo sign does not further increase the sensitivity and specificity of US (C. Duftner, personal communication). without ‘gold standard’ [13]. Cambridge: University Press; 2001. Symptoms of temporal arteritis. involvement in giant cell arteritis. The main symptoms are: frequent, severe … For all scenarios, κ values were >0.8, suggesting almost perfect agreement [34]. Establishing the diagnosis of giant cell arteritis (GCA) remains challenging. Halo sign of temporal artery frontal branch, Compression sign of temporal artery branches. cell arteritis and 15 patients had received glucocorticoid treatment. treatment currently available for giant cell arteritis and corticosteroid therapy review. The time interval between onset of symptoms and diagnosis is longer, but visual loss is less common [15–20]. All authors have reviewed and approved the submitted manuscript for This may reflect poor consistency of the scanning technique, due to the lack of a standardised scanning protocol. standardization of ultrasound equipment, image acquisition, and probe settings are Despite this caveat, it is clear that TAB is less sensitive than US in most studies, particularly because TAB evaluates only a limited anatomical region in a systemic disease. Newer techniques may be of more use in detecting potential markers of disease activity. A biopsy used for statistical analysis. Arthritis Care Res. Despite the absence of scientific data, US is regarded as strongly investigator dependent. Alternatively, the US examination can be performed in a timely manner by a vascular specialist [4, 58]. probe at 13 MHz frequency (Esaote SpA, Genoa, Italy for B-Mode) and 10 MHz A recent prospective study to establish cut-off values was performed in patients with GCA and matched controls [12]. Cookies policy. If appropriate, spectral and color Doppler imaging may be performed to determine the presence and nature of blood flow in the region of the suspected abnormality. The role of temporal artery US for monitoring disease activity is still unclear, and studies are under way to address this question. experiences). The possible justification for the same was that there would be a patchy There is a recognized female predilection. Probes with frequencies >20 MHz are increasingly available, and such probes allow the normal IMC of temporal arteries to be clearly visualized. it was considered as occluded (Fig. 6). Additionally, almost all other large arteries, with the exception of the thoracic aorta, can be easily delineated by US. lies in the first week after its diagnosis [8]. Myklebust G. Diagnostic value of color Doppler ultrasonography of temporal In a web-based reliability test of temporal and axillary artery images and videos of patients with GCA and controls, following the strict rules of OMERACT-related US exercises, the OMERACT US group also arrived at κ values of >0.8 for inter-observer and intra-observer agreements for halo and compression signs [36–40]. significantly reduces permanent visual impairment: towards a more effective b. 1) [6] (C. Duftner, personal communication). Gadolinium (Omniscan) was purchased from Rheumatology vasculitis classification criteria still valid? Uhl M, Vaith P, Langer M. Comparison of duplex sonography and high-resolution The doctor will also examine the patient's head to look for scalp tenderness or swelling of the temporal … Age ≥50 years. The results of the study Five patients (36%) fulfilled the 1990 American College of Rheumatology classification criteria. (Fig. 10). Detailed process flowchart of ultrasound Zou, Q., Ma, S. & Zhou, X. RETRACTED ARTICLE: Ultrasound versus temporal artery biopsy in patients with Giant (Fig. 2) [15]. All wall with a halo. This may reflect poor consistency of the scanning technique, due to the lack of a standardised scanning protocol. bruits on either side were examined by ophthalmologists (minimum 3-years’ pathologists (all evaluators had minimum 3 years of The criteria are age above 50, new headache, tenderness or reduced pulsation in the temporal artery, increased erythrocyte sedimentation rate (measured with a simple blood test), and an abnormal artery biopsy. Few studies have been published that compare US directly with other imaging modalities. Â¥/patient vs. 18,551 ± 1231 Â¥/patient, p < 0.0001, Fig. 11). If arteries are small or localized deeply, the segment to be biopsied may be marked with the aid of US [43]. cell arteritis [5]. Open Access This article is distributed Rheumatology departments are increasingly establishing fast-track clinics. overdiagnosis and overtreatment in giant cell arteritis. Very large populations with giant cell aspects of work ensuring integrity and accuracy. patients’ record of the institute(s) and pharmacy. A randomized study, Comparison between colour duplex sonography findings and different histological patterns of temporal artery. US is more sensitive than temporal artery biopsy (TAB) because TAB evaluates only a limited anatomical region in a systemic disease. ultra-sonographer(s) [23]. cross-sectional views. Arthritis Rheum. Color duplex ultrasonography of the temporal artery has emerged as a promising alternative or complement to TAB. [ 97, 98, 99, 100, 101, … and clinical features examinations following temporal artery biopsy Experienced sonographers may, however, consider stenosis of temporal arteries an additional feature for confirming the diagnosis if a halo sign is present. Fluid, as represented by effusion or artery lumen, is anechoic (black). Temporal arteritis refers to the condition in which there is an inflammation or damage of the temporal arteries in the brain which. MR hospital of Lanzhou University, Lanzhou, China. of the original), Pictorial presentation of the occluded artery Temporal arteritis (giant cell arteritis or cranial arteritis) is an inflammation of the lining of your arteries. physical and clinical features interpretations were performed by time for physical/ clinical features examinations following ultrasound detection During US examination, this is characterized by the absence of colour Doppler signals in a visible artery filled with hypoechoic material, even with low pulse repetition frequency and high colour gain [6] (C. Duftner, personal communication). Both studies show that US images and videos can reliably document GCA diagnosis. 2013;5:23–33. The doctor will perform a physical examination and will check to see whether the patient's pulse is weak. Rheumatol. As GCA is considered a medical emergency, it is treated at the point of diagnosis by clinicians in primary and secondary care who have a wide variety of clinical backgrounds. US provides by far the highest resolution of all imaging techniques. Do temporal artery duplex ultrasound findings correlate with ophthalmic complications in giant cell arteritis? and socioeconomic costs [20]. If high-grade proximal subclavian artery stenosis or occlusion is present, reverse flow from cranial to caudal may be found in the vertebral arteries as a result of subclavian steal syndrome. 3T MRI reveals extra- and intracranial involvement in giant cell Glucocorticoid treatment rapidly decreases the sensitivity of imaging. In respect Adequate US equipment for diagnosing GCA is widely available in rheumatology practice. Article  Lower systemic inflammatory response With modern ≥15 MHz transducers, a temporal artery halo is usually detectable in stenotic segments. published maps and institutional affiliations. agreement for the physical and clinical features interpretations was outstanding radiation involved in ultrasound [13]. Temporal arteritis is sometimes diagnosed clinically, but a temporal-artery biopsy is generally recommended to confirm the diagnosis. Angiography is also limited by radiation exposure and invasiveness; as a result, it has no role in the diagnosis of GCA and should be used only when interventions are needed. Bley TA, Geiger J, Jacobsen S, Wieben O, Markl M, Vaith P, Grist T, cell arteritis: an audit. Jakpor OA, Fraser JA, Tyndel FJ, Sundaram AN, Liu X, Lam CT, Patel V, Weis E, US examination is non-invasive and cost-efficient [1, 2]. In acute GCA, US displays a non-compressible, hypoechoic, most commonly concentric arterial wall thickening. The prospective study included 57 patients with suspected temporal arteritis who underwent Doppler ultrasound of both temporal arteries and temporal artery biopsy. Temporal arteritis (giant cell arteritis) is where the arteries, particularly those at the side of the head (the temples), become inflamed. (Mediant, Maciej Frankiewicz, Poznan, Poland). There are no predefined has received consultant fees from Roche, GlaxoSmithKline and Bristol-Myers Squibb, research support from Roche and GlaxoSmithKline and speaker’s bureau fees from Roche, Medac and Bristol-Myers Squibb. magnetic resonance images were analyzed by radiologists, the 2), non-compressible arteries (compression sign; Fig. Ultrasound of proximal upper extremity arteries to increase the diagnostic yield including branches, both (right and left) parietal ramus, both (right and left) However, Decision curve analysis.

Open Access Rheumatol. low-risk giant cell arteritis patients) for ultrasound detection and above 86% [16]. In recent studies, ultrasound examination of the superficial temporal artery was shown to have a … In another study, the inter-observer agreement for the diagnosis of GCA between two sonographers from one institution evaluating the compression sign of temporal arteries was excellent, with the two sonographers disagreeing only in 1 of 60 patients [35]. examinations following ultrasound detection > physical and clinical features examinations (14,023 ± 982 Â¥/patient vs. 18,551 ± 1231 Â¥/patient, p < 0.0001) and MRI. Diagnosis of giant cell arteritis by temporal artery biopsy is publication. Nevertheless, the main benefits of US over TAB are time and cost. Manage cookies/Do not sell my data we use in the preference centre. Glucocorticoid treatment should be started immediately, particularly if the appointment might be delayed for some reason (e.g. Imaging in diagnosis, outcome prediction and monitoring of large vessel vasculitis: a systematic literature review and meta-analysis informing the EULAR recommendations. The interobserver agreement was derived by Cohen protocol is not specifically adjusted to depict mural inflammation of the Patients with recent visual impairment, C-reactive protein level Again, this can be compared with arthritis with non-compressible synovial proliferation but compressible effusion. hypoechoic ring around the temporal artery wall a.

Therefore, training is The sample of blood was collected from each patient and send to a Springer Nature remains neutral with regard to jurisdictional claims in field of view and the contrast enhancement of walls of arteries would also be due to enrollment. GCA typically occurs in people 50 years of age or older and is more common in women. Subject is scheduled for TAB based on clinical diagnostic protocol. Physical and clinical features examinations following ultrasound dose of glucocorticoid as precaution. Extracranial artery wall swelling may remain detectable for longer durations [17]. That for distal frontal ramus was 2.5 cm However, there are some discrepancies regarding itsdiagnostic strength, poi… The surrounding tissue is more hyperechoic and heterogeneous in periaortitis (Fig. available studies are full-filled the American College of Rheumatology (ACR) 1990 Three of the following five criteria must be met for the diagnosis: age > 50 years, new onset of localized headache, temporal artery tenderness or decreased pulse, erythrocyte … Temporal arteritis is a form of vasculitis (inflammation of the blood vessels). The proximal left common carotid artery and the proximal left subclavian artery can be seen only with a lower resolution because they run deep to the US probe. Th e Rheumatology. radiologists were involved in the interpretations of physical and clinical The author agrees to be accountable for all ABSTRACT Objective. In extracranial arteries such as the axillary arteries, wall thickening usually remains for months or years [5, 17, 20], probably reflecting a larger oedematous mass of these arteries. Are the 1990 American College of Rheumatology vasculitis classification criteria still valid? observational studies in epidemiology (STROBE) statement, and the 2008 Helsinki The halo sign alone is a sensitive marker in the diagnostics of GCA. In contrast to temporal, axillary, occipital and facial arteries, arteriosclerosis of carotid arteries is common among the age group of patients with suspected GCA, often with stenosis of internal and external carotid arteries. were evaluated for 3 cm or more in length (Fig. 3) [12].
