Thank you for updating your details. Familiarity with its CT appearances can aid the radiologist to make the appropriate diagnosis. The pulmonary arteries are also commonly involved, with the most common appearance being peripheral pruning. Atherosclerotic plaques are more common in patients aged 45 years and above, and not usually associated with long segment luminal stenosis [ 1423 ].

It may also affect the pulmonary arteries. Takayasu arteritis as a cause of arterial hypertension.
Acta Societatis ophthalmologicae JaponicaeTokyo Other search option s Alphabetical list. Journal List Br J Radiol v. Takayasu arteritis is a chronic, idiopathic, inflammatory disease that primarily affects large vessels, such as the aorta and its major branches and the pulmonary and coronary arteries.
The stenotic lumen is also visualized. From Wikipedia, the free encyclopedia. This article has been cited by other articles in PMC.
TA is a rare clinical condition that is characterized by chronic panarteritis of the aorta and its primary branches, including the subclavian, common carotid, coronary and renal arteries, and may result in localized stenoses, vascular occlusion, dilatation and aneurysm formation 8. In patients with symptomatic stenotic or occlusive lesions, percutaneous transluminal angioplasty and stenting or bypass surgery is the most common palliative treatment [ 12 ].
Takayasu arteritis—advances in diagnosis and management. Coronary CT angiography in Takayasu arteritis. Histopathology reveals TA as granulomatous panarteritis characterized by T lymphocytes, B lymphocytes, macrophages and multinucleated giant cells infiltration of the arterial wall [ 13 ].
Circ Genom Precis Med 11 In the present study, the patient’s clinical symptoms were not evident, although his ESR was raised; this indicated inflammatory activity.

Prognosis tends to be variable ranging from a rapidly progressive disease in some reaching a quiescent stage arteritw others. In the present study, a case of common carotid artery dissection in a young patient with TA, without evident clinical manifestations, is presented.
In other projects Wikimedia Commons. There is often anaemia with raised inflammatory markers. Epidemiology and pathology TA has an annual incidence of 2. Females are about 8—9 times more likely to be affected than males. CT angiography features Mural thickening The typical manifestation for TA on CT images is the concentric mural thickening of the involved arteries Figure 2.
The intimal dissection in the common carotid artery may be associated with chronic inflammation of the vessel wall, vulnerable intima and hyperdynamic flow. Nuclear medicine is limited by a lack of standardized technique and high cost, while ultrasonography suffers from operator-dependent artefacts from overlying structures and bowel gas.
Other non-invasive imaging modalities Nuclear medicine, ultrasonography and magnetic resonance angiography MRA are all potentially useful for diagnosis and evaluation of TA. With regard to the branches, stenotic lesions are most frequently founded in the subclavian and common carotid arteries, followed by the renal arteries Figure 6 [ 17 – 9 ].

National Center for Biotechnology InformationU. Multiple small aneurysm formation in the involved artery is the characteristic manifestation on CTA images Figure 13 [ 24 ]. This mechanism of chronic inflammation may result in a moving intimal flap in the involved artery, which is another unique character of intimal injury
