[Balloon angioplasty of branches of the aortic arch].

Balloon angioplasty has become a first-line therapy of symptomatic brachiocephalic occlusive disease. We review our own results of treatment of these lesions for the last two years. 16 patients (18 vessels--6 occlusions) with chronic limb ischaemia (9 cases), vertebrobasilar insufficiency (4 cases), ischemic stroke (2 cases); in one case angioplasty was performed as prevention before major abdominal surgery. Femoral approach was predominantly used; in 3 occlusions brachial approach was chosen. Stents were implanted in 4 cases of poor angioplasty result with severe limb ischaemia. Lesions were crossed in all stenoses and in 4 of 6 occlusions. Residual stenosis < 30% was attained in 10 pts. In 11 cases transstenotic gradient was relieved and a normal flow in vertebral artery was reestablished. There were two cases of acute upper limb ischaemia, one needed surgery. Reversible ulnar nerve paresis was noted in one patient, transient symptoms of postreperfusion syndrome in two. At follow up (mean 12 mo, range 1-30 mo) 1 restenosis was recorded. Balloon angioplasty is easy, safe and effective for treating brachio-cephalic stenoses. Recanalisation of occlusions is more difficult and risky. Treatment of stenoses should not be undully postponed; recanalisation should be reserved for patients with more advanced symptoms of the disease.
