摘　　要：BACKGROUND Aortic arch stenting is continuously emerging as a safe and effective option to alleviate aortic arch stenosis and arterial hypertension.CASE SUMMARY We present a 15-year-old girl with aortic arch hypoplasia who had undergone implantation of an uncovered 22 mm Cheatham-Platinum stent due to severe(native)aortic arch stenosis.On follow-up seven months later,she presented a significant re-stenosis of the aortic arch.A second stent(LD Max 26 mm)was implanted and both stents were dilated up to 16 mm.After an initially unremarkable post-interventional course,the patient presented with hoarseness five days after the intervention.MRI and CT scans ruled out an intracranial pathology,as well as thoracic hematoma,arterial dissection,and aneurysm around the intervention site.Laryngoscopy confirmed left vocal fold paresis attributable to an injury to the left recurrent laryngeal nerve(LRLN)during aortic arch stenting,as the nerve loops around the aortic arch in close proximity to the area of the implanted stents.Following a non-invasive therapeutic approach entailing regular speech therapy,the patient recovered and demonstrated no residual clinical symptoms of LRLN palsy after six months.CONCLUSION Left recurrent laryngeal nerve palsy is a rare complication of aortic arch stenting not previously reported.BACKGROUND Aortic arch stenting is continuously emerging as a safe and effective option to alleviate aortic arch stenosis and arterial hypertension.CASE SUMMARY We present a 15-year-old girl with aortic arch hypoplasia who had undergone implantation of an uncovered 22 mm Cheatham-Platinum stent due to severe(native) aortic arch stenosis.
