Abstract:
Objective To evaluate the technique and result of endovascular treatment for right subclavian artery stenosis or occlusion.Methods Seventeen patients [13 males,4 females ; (56 ± 11)years old] with right subclavian artery stenosis or occlusion were treated with endovascular surgery which included recanalization,balloon angioplasty and stenting via femoral or brachial artery route.Cerebral protection devices were used in 6 cases to avoid cerebral embolism.Results Sixteen of the seventeen patients acquired successful recanalization in 8 cases with subclavian artery stenosis (100％ technical success rate) and in other 8 cases with subclavian artery occlusion (88.9％ technical success rate).Five cases were treated with balloon angioplasty,and 11 cases were treated with balloon angioplasty combined with stenting.Good patency was seen in the 16 cases immediately after the procedure.The cerebral protection devices prevented all the cases from cerebral embolism and were retrieved suceessfully.Sixteen cases were followed up from 1 to 66 months [mean (24 ± 18) months].Restenosis was found in one case 10 months later and was successfully treated with re-PTA.One case with aortoarteritis died of cerebral infarction 18 months later.No symptom recurrence was found in other cases and ultrasound or CTA of followup showed excellent patency.Conclusions Balloon angioplasty and stenting are safe and effective for the treatment of right subclavian artery occlusion.
