OBJECTIVES: The objective of this report is to elucidate the feasibility of the frozen @entity7105 trunk technique as a one-stage operation for extensive @entity439 and to investigate the long-term durability and efficacy of this procedure from our 11 years of experience. METHODS: The subjects were 58 consecutive @entity1 who electively received the frozen @entity7105 trunk technique for @entity439 involving the aortic arch and the descending aorta between September 1997 and September 2008. Concomitant procedures included 15 coronary artery bypass grafts, 2 aortic valve replacements, 1 aortic root replacement, and 3 maze procedures. The stent graft was delivered to the seventh thoracic vertebra level (Th7) in 22, Th8 in 26, Th9 in 8, and Th10 in 2 @entity1 . Cerebrospinal fluid drainage was administered preoperatively in 10 (17.2%) @entity1 . RESULTS: Operative mortality within 30 days was 0 of 58. There was 1 in-hospital death. Perioperative morbidity included @entity64 and @entity1566 in 2 (3.4%) @entity1 each. During the mean follow-up period of 54.2 +/- 36.9 months, there were 9 (15.5%) late deaths, and 7 (12.1%) @entity1 required additional intervention. The 8-year survival was 65.5%, the overall 8-year aortic event free survival was 72.8%, and the 8-year event free survival on the site of the stent graft was 94.8%. A follow-up computed tomographic image was available for 86.2% (50/58) of @entity1 who survived longer than 6 months. The size of the @entity439 increased in 1 (2.0%) @entity1 , was not changed in 6 (12.0%) @entity1 , shrank in 34 (68.0%) @entity1 , and was obliterated in 9 (18.0%) @entity1 . CONCLUSIONS: The frozen @entity7105 trunk for extensive @entity449 had long-term durability and efficacy and might become the alternative treatment for extended aortic replacement.
