Abstract PurposeTo examine the safety, feasibility, and mid-term efficacy of the chimney technique for aortic arch pathologies.MethodsFrom February 2011 to December 2014, a total of 35 patients (30 men; mean age 54.3 ± 14.1 years) with aortic arch pathologies underwent thoracic endovascular aortic repair combined with chimney stents. The indication was a proximal landing zone <1.5 cm. Follow-up was performed at 3, 6, and 12 months and then yearly thereafter.ResultsA total of 36 chimney stents were deployed (innominate artery, n = 1; left common carotid artery, n = 9; right subclavian artery, n = 1; left subclavian artery, n = 25). The technical success rate was 94.3 % (33/35). Immediate type Ia endoleaks (ELIa) were observed in two patients (8.6 %, 2/35). Twenty-five patients were successfully followed-up for a median period of 29.3 months (range, 6–48 months). One patient died due to aortic dissection aneurysm rupture at 36 months (mortality rate of 4 %, 1/25). Three late ELIa were observed and no reinterventions were performed. The overall incidence of ELIa was 20 % (5/25). During follow-up, the patency rate for chimney stents was 92 % (23/25).ConclusionOur limited experience demonstrates that the chimney technique is a viable and relatively safe treatment for patients with challenging thoracic aortic pathologies at least in the mid-term follow-up period.
