OBJECTIVES: This study sought to determine whether several anatomic or evolving characteristics of the @entity1498 may create challenging conditions for treatment. BACKGROUND: Stent repair of @entity1498 of aorta is an alternative to surgical correction. METHODS: We analyzed our 21-year experience in the percutaneous treatment of @entity1498 . Adverse conditions for treatment were as follow: 1) complete interruption of the aortic arch (n  = 11); 2) associated @entity439 (n  =  18); 3) complex @entity850 (n  = 30); and 4) the need for re-expansion and/or restenting (n  = 21). Twenty @entity1 (33%) belonged to more than 1 group. Ten interruptions were type A and 1 was type B. The mean length of the interrupted aorta was 9    11 mm. The associated @entity439 were native in 8 @entity1 and after previous intervention in 10  @entity1 . @entity439 shapes were fusiform in 8 @entity1 and saccular in 10. The following characteristics @entity850 as @entity6632 , or @entity850 involving a main branch or an unusual location. @entity1 previously stented at an early age, required re-expansion and/or restenting after reaching 16    5 years of age. RESULTS: Two @entity1 had died by 1-month follow-up. The remaining 58 @entity1 did well and were followed-up for a mean period of 10    6 years. Late adverse events occurred in 3 @entity1 (5%). All remaining @entity1 are symptom-free, with normal baseline blood pressure. Imaging techniques revealed good patency at follow-up without associated @entity439 or @entity256 . The actuarial survival free probability of all complex @entity1 at 15 years was 92%. CONCLUSIONS: Stent repair of @entity1498 is feasible and safe. Initial results are maintained at later follow-up.
