asymmetric brachial blood pressure

Etiology

• atherosclerosis, atheroma, peripheral arterial disease, subclavian stenosis
• *compression of the subclavian artery or brachial artery due to mass lesion in upper chest or axilla
  • thoracic outlet syndrome
  • Pancoast tumor
  • axillary nodes
• arterial thrombosis of brachial artery or axillary artery
• subclavian steal syndrome
• aortic dissection
• acute aortic syndrome
• Takayasu's arteritis
• giant cell arteritis
• *congenital disorders
  • anomalous origin of the innominate artery
  • anomalous origin of the right subclavian artery

Epidemiology

• age is only consistent predictor of unequal brachial BP

Complications

• increased cariovascular risk & increased mortality

More general terms

• sign/symptom
