[Subclavian steal syndrome. Clinical aspects and therapeutic problems].
Cerebrovascular disease is a leading cause of morbidity and mortality in Italy. Although atherosclerotic involvement of the carotid artery is more prevalent, some patients suffer from stenosis of the subclavian artery, usually proximal to the origin of the vertebral artery. Neurological symptoms result from reversed flow in the vertebral artery, so-called "subclavian-steal". This collateral pathway may rob the posterior circulation of perfusion to the degree of producing episodes of vertebrobasilar insufficiency. The authors have therefore reviewed their experience with this disease and present their findings, therapeutic procedures and short-term results. During 1990 four patients affected by "subclavian-steal syndrome" were observed at the Surgical Department of Montecchio Maggiore Hospital (VI). Two patients were operated on and axillo-axillary bypass operations were performed (with a 5 mm Gore-tex graft). The goal of surgical treatment is to alleviate cerebrovascular symptomatology by restoring flow to the subclavian artery distal to the occlusion. Axillo-axillary bypass offers distinct advantages over the alternative methods such as transthoracic procedures or carotid-subclavian bypass. Axillo-axillary bypass is a technically simple procedure with very good results and minimal complications. It avoids sternotomy, thoracotomy and clavicular resections: the carotid artery is not involved in the procedure. The authors conclude that axillo-axillary bypass is a cheap, safe and effective treatment for symptomatic subclavian artery insufficiency.
