[Reimplantation of the subclavian artery into the common carotid artery].

Since 1973, transposition of the subclavian artery into the common carotid artery has been the technique of choice to treat prevertebral occlusive subclavian lesions. However, the haemodynamic results in the vertebral artery were far from perfect, as shown by immediate post-operative ultrasonic examinations. This has been corrected by a technical modification: the subclavian artery is severed flush with the vertebral artery lying obliquely downward and medially, which is equivalent to reimplanting a "double-barrelled" vessel (the vertebral and subclavian arteries) into the common carotid artery.
