title: Endoluminal repair of distal aortic arch aneurysms causing aorto-vocal syndrome.
abstract: OBJECTIVE
  We have evaluated the efficacy of endovascular repair of distal aortic arch aneurysms (DAAA) causing recurrent laryngeal nerve palsy.
  
  
  METHODS
  Eight patients (five male and three female) with median age of 72 years (range: 59-80) presented with left recurrent laryngeal nerve palsy associated with DAAA. All patients were considered unfit for open surgery. The median aneurysm size was 5.9 cm (range: 5-7.3). Thirteen stents were deployed: eight Gore, four Endofit and one Talent. Epidural anaesthesia was used in all patients. The left subclavian artery was covered in all and the left common carotid in three who had a preliminary right to left carotid-carotid bypass. Routine follow-up (FU) was with computed tomography (CT) at 3-6 months and yearly thereafter.
  
  
  RESULTS
  Exclusion of the aneurysm sac was achieved in all patients. Thirty-day mortality was 0%, with no paraplegia or stroke. Early complications included: rupture of the external iliac artery (one) and common femoral artery thrombectomy (one). One patient died of unknown cause at 17 months. The mean FU in the remaining seven patients was 21 months (range: 6-51). Aneurysm size decreased in five, was unchanged in one and increased in one. Three patients had improvement in voice quality postoperatively. One patient had a recurrent type 1 endoleak which was restented twice. No late deaths have occurred.
  
  
  CONCLUSIONS
  Though technically the procedures involved were more complicated, endovascular repair of DAAA causing aorto-vocal syndrome is safe and offers a realistic alternative to open surgery. Hoarseness of the voice can improve postoperatively and is associated with reduction in aortic sac diameter.
