[Subclavian transposition and carotid-subclavian bypass in the treatment of subclavian steal syndrome].

The authors operated on 89 patients for subclavian-steal syndrome, between 1975 and 1984. A carotid-subclavian bypass was applied to 53 patients and transposition of the subclavian artery to another 36. All transpositions were open after an average follow-up period of 2.7 years, where an occlusion was recorded after 4.6 years from eight patients (19.5 per cent) to whom a bypass had been applied. Postoperative complications were equal in both groups. A complex of Horner symptoms was recorded from either group. Phrenoparalysis was recorded from six patients with carotid-subclavian bypass and from four patients with subclavian transposition.
