In addition, an intimal dissection in the common carotid artery was identified, which is not typically a unique imaging finding of TA. Case 4 Case 4. Percutaneous angioplasty and bypass surgery should only be considered when there is no acute inflammation.
Assessment of disease activity and progression in Takayasu’s arteritis. The intimal dissection in the common carotid artery may be associated with chronic inflammation of the vessel wall, vulnerable intima and hyperdynamic flow.
Aortic dissection in the common carotid artery is an unusual pathologic characteristic of TA and has been rarely reported 7. TA has an annual incidence of 2. The stenotic lesions usually appear as concentric narrowing of the arterial lumen Figure 8.
Author information Article notes Copyright and License information Disclaimer. In tamayasu with an advanced stage of TA, intimal defects may rarely occur as a result of stenosis, which can cause insufficient blood flow to downstream vessels and decreased blood flow velocity.

Imaging characteristics of Takayasu arteritis.
It is now known that the blood vessel malformations that occur in the retina are an angiogenic response to the arterial narrowings in the neck and that the absence of pulses noted in some people occurs because of narrowings of the blood vessels to the arms. Clinical examination and satisfactory imaging are crucial for the correct diagnosis and management of patients with TA with dissection in arteries, and great attention is required arerite order to prevent the occurrence of cerebrovascular ischemia.
China Find articles by Jie Zhang. Diagnostic imaging in Takayasu arteite. Since large-artery biopsies cannot easily be done, imaging examination is essential for providing the diagnosis and differential diagnoses in patients with suspected TA.
