What are the causes of absent radial pulse ?

What are the causes of absent radial pulse ? • Aberrant radial artery or congenital anomaly (check the brachials and blood pressure). • Artery tied off at surgery or previous surgical cut-down. • Catheterization of the brachial artery with poor technique. • Following a radial artery line for monitoring of blood gases or arterial pressure. • Subclavian artery stenosis. • Blalock-Taussig shunt on that side (shunt from subclavian to pulmonary artery). • Embolism into the radial artery (usually due to atrial fibrillation). • Takayasu's arteritis (rare).
