We present our experience with 105 patients in whom percutaneous transluminal angioplasty was performed in 112 stenosed or occluded supra- aortic arteries.Symptoms of cerebrovascular and/or vertebrobasilar insufficiency were present in 104 of the 105 patients.The angioplasty was successful in 35 stenoses of the internal carotid artery,2 stenoses of the common carotid artery,1 stenosis of the external carotid artery,15 stenoses of the vertebral artery,3 stenoses of the innominate artery and 44 stenoses of the subclavian artery.There were only 4 minor-complications (2 haematomas,1 transient ischemic attack,1 small thrombus of the internal carotid artery which was detected by 111-indium platelet scintigraphy and treated by thrombendarterectomy before the appearance of neurological symptoms).All patients were symptom free after angioplasty.During the observations period of 3 to 109 months(average 58 months)there were only two cases with re-stenosis after subclavian angioplasty.The results of more than 700 personal and international published percutaneous transluminal angioplasties of supra-aortic arteries are presented.The results suggest that angioplasty of supra-aortic arteries is an effective method.On strict definition of the indications,the complication rate for angioplasty of the supra-aortic arteries is not likely to be higher than that for operative treatment. |
