Key clinical features to consider when diagnosing Takayasu arteritis in a young adult include:

  • Constitutional symptoms: Patients often present with systemic features such as fever, malaise, weight loss, and fatigue, reflecting the inflammatory nature of the disease .
  • Vascular symptoms and signs: These include limb claudication (especially upper limbs), diminished or absent peripheral pulses, blood pressure discrepancies between arms, and bruits over large arteries such as carotid or subclavian arteries .
  • Hypertension: Secondary hypertension is common due to renal artery involvement or aortic coarctation .
  • Neurological symptoms: Dizziness, syncope, or visual disturbances may occur due to carotid or vertebral artery involvement .
  • Arterial inflammation signs: Tenderness or pain over affected arteries, and in some cases, features of ischemia such as ulcers or gangrene in severe disease .
  • Laboratory findings: Elevated inflammatory markers such as ESR and CRP support the diagnosis but are nonspecific .

In summary, the diagnosis in a young adult relies on recognizing a combination of systemic inflammatory symptoms and characteristic large-vessel ischemic signs, supported by laboratory and imaging findings .
