The aortic stent-grafts were deployed in zone 0 (n=22), zone 1 (n=13), or zone 2 (n=191).Results: The technical success rate was 84% (189/226) and immediate type Ia endoleak (ELIa) happened in 37 (16%) patients. The 30-day mortality and morbidity rates were 2% (4/226) and 4% (8/226), respectively. Major adverse events include four major strokes, three spinal cord ischemia and one aortic rupture in the early-term. The clinical and imaging follow-up rates were 98% (218/222) and 78% (173/222), respectively. The average lengths of clinical and imaging follow-up were 22±16 months and 20±15 months, respectively. Chimney stent obstructions in left subclavian arteries were recorded in six (3%) patients. During follow-up, five patients died (2%) and two major strokes occurred (1%). One patient (0.5%) underwent reintervention.Conclusion: The current study documented that the chimney technique is effective and safe for treating aortic arch diseases in different aortic zones. Cautions are needed to assess the permanency of chimney stent and to reduce the immediate ELIa rate.Keywords: aortic arch disease, chimney, endoleak, thoracic endovascular aortic repair |
