title: Secondary interventions after elective endovascular repair of degenerative thoracic aortic aneurysms: results of the European collaborators registry (EUROSTAR).
abstract: OBJECTIVE
  The need for secondary interventions is an important indicator of intermediate and long-term success of endovascular repair of degenerative thoracic aortic aneurysm. The purpose of this study was to analyze the occurrence and consequences of secondary procedures.
  
  
  METHODS
  Data from 213 patients electively subject to operation for degenerative thoracic aortic aneurysm and achieving primary success and who were enrolled in the EUROSTAR registry were analyzed. Secondary procedures were categorized as follows: transfemoral endovascular reintervention, extraanatomic secondary procedures, and transthoracic surgery.
  
  
  RESULTS
  Overall, 25 (12%) of the patients with an elective treatment for a degenerative thoracic aneurysm had secondary intervention, occurring at a mean of 8 months after the initial procedure. Seventeen (68%) of the secondary interventions were via a transfemoral approach, six (24%) involved a transthoracic procedure, and two (8%) involved extraanatomic bypass. The cumulative percentage of freedom from intervention at 1 and 2 years was 86% and 83%, respectively. Endoleak (relative risk, 5.21) was the most frequent cause for secondary transfemoral intervention. For the other secondary interventions, no principal indication for reintervention could be identified. Patients who needed secondary interventions more frequently suffered from preoperative back pain (20% vs 44%, P = .008), and their thoracic aneurysms had a longer length (mean, 95.6 mm vs 133.2 mm, P = .006). The 2-year cumulative survival rate of patients without secondary intervention was 85% compared with 58% in the patients who received secondary intervention (P = .0001).
  
  
  CONCLUSIONS
  Regular surveillance after endovascular degenerative thoracic aneurysm repair is needed as secondary interventions were required throughout the follow-up period.
