Abstract

Significant stenosis or complete SA subclavian artery occlusion is a relatively rare illness; it occurs in about 0.4% of the population. In 90% of cases atherosclerosis is the cause of subclavian artery (SA) occlusion or stenosis. Occlusion or hemodynamically significant stenosis (> 70%) may lead to the development of symptoms in the form of cerebral ischaemia or upper limb ischaemia. SA stenosis can be treated by both classical techniques and with the use of endovascular techniques. In connection with comparable results of the primary patency and a lower risk of the procedure itself, endovascular techniques are at present the primary treatment of SA stenosis or occlusion. In the presented paper the case of application of the MISAGO (Terumo) self-expanding stent, belonging to the new generation of peripheral self-expanding stents based on a monorail system, in the treatment of a 7 cm long lesion in the proximal left subclavian artery is presented. In the authors’ opinion, long-section lesions require the use of a flexible stent resistant to bending or deflection. The Misago (Terumo) stent can be successfully used in endovascular treatment of extra-ostial lesions of the subclavian artery.
