Curative effect of angioplasty and stenting on proximal arcus aortae stenosis

Abstract

Objective To investigate the application of angioplasty and stenting in the treatment of proximal arcus aortae stenosis. Methods and Results From January 2015 to June 2018, 13 patients with proximal stenosis of superior aortic arch including 5 patients with anonymous stenosis, 5 patients with right common carotid artery (CCA) stenosis and 3 patients with left CCA stenosis were treated by stenting. Eleven Express LD balloon-expanding stents and 2 Wallstent self-expanding stents were implanted. No thrombus protective umbrella was used during stent release in 4 patients (one case of anonymous artery stenosis and 3 cases of left CCA stenosis). One case of anonymous artery stenosis showed small cortical infarction 3 d after operation. Six months after operation, CTA showed restenosis in stent in one case with anonymous artery stenosis. The restenosis rate was more than 50%. Conclusions Stenosis of anonymous artery and CCA can be treated by angioplasty and stenting. The stability of the guide catheter and the recovery of the filter devices should be considered during the operation. The perioperative and long-term results are satisfactory.
