Talayasu MRA and CTA provide cross-sectional arterial wall images and allow detection of intramural inflammation, and they both demonstrate high specificity and sensitivity for the diagnosis and disease activity assessment — C-reactive protein and other inflammatory biomarkers. A 3D reconstruction CT images of the whole aorta in a 12 year-old female Takayasu arteritis patient with thoraco-abdominal aortic aneurysm bracket proximal to a stenotic lesion arrow at the renal artery emergence site.
Female, 7 year-old patient with Takayasu arteritis. Takayasu Arteritis Molecular mimicry between the mycobacterial kDa heat-shock protein HSP and human kDa HSP has been suggested, which could elicit an immunologically-mediated cross-reaction and lead to an autoimmune response Takayasu arteritis in children: Nomenclature and classification of vasculitis: Semin Roentgenol, 5pp.
Introduction Takayasu arteritis TA is an idiopathic, granulomatous, large-vessel arteritis that predominantly involves the aorta, its major branch arteries, and less frequently the pulmonary arteries 1.
Gedalia A, Cuchacovich R. Typical features of childhood TA in angiography and MRA imaging are—similarly to findings in adult patients—stenosis, fusiform dilatations, aortic wall thickening, mural thrombi, and a bright signal in T2-weighted images indicating inflammatory edema of the vessel wall Takayasu arteritis in children and young Indians.
Complications due to ischemia, vitreous hemorrhage, retinal detachment, or optic atrophy may lead to blindness Cutaneous features Cutaneous features have been observed in 2.

Percutaneous transluminal angioplasty with balloon or stenting have long been used in TA, but despite providing short term benefit, re-stenosis, and aneurysmal formation are frequent and may occur within 1 or 2 years, and justify new interventions such as bypass surgery 24, — Performance of Birmingham Vasculitis Activity Score and disease extent index in childhood vasculitides.
Journal List Front Pediatr v. Children treated with biologic agents carry significantly better outcomes as compared to children treated with non-biologic therapies. Approximately one third of patients have no elevated inflammatory markers at presentation. Carotidynia may be aggravated by swallowing, coughing, sneezing, or turning the head to the contralateral side 76 Laboratory and biomarkers There are no specific laboratory tests for TA or available validated biomarkers of disease activity which could be useful for clinical care or clinical trials.
