MESA BARRERA, Yoany et al. Syndrome of subclavian steal. Rev Cub Med Mil [online]. 2014, vol.43, n.2, pp.269-273. ISSN 0138-6557.

A 46 year-old female patient with a history of hypertension and regular smoker complained of isolated and brief episodes of dizziness, postural instability, faint feeling without altered consciousness, after exercise the left arm for 2 years. Her neurological examination showed asymmetry of carotid and radial pulses. Her extracranial doppler revealed carotid atherosclerotic changes in both axes, with 50 % right stenosis, decreased flow of the proximal left vertebral artery and obstruction of the proximal left subclavian artery. Subclavian Steal Syndrome is a rare condition. Its diagnosis is clinical and it is demonstrated by Doppler or angiography. Treatment should be determined individually in each case.

Palabras clave : subclavian artery; vertebral artery; subclavian steal syndrome.
