OBJECTIVE: The goal of this study was to present open surgical conversion with graft salvage or "semiconversion" as a definitive and safe treatment for untreatable and persistent @entity1070 causing sac enlargement after @entity439 repair. METHODS: Between January 2001 and December 2014, 25 of 1623 endovascular aortic repair (EVAR) @entity1 were selected as candidates for open semiconversion. The indication was persistent @entity1070 in 13 @entity1 (12 of whom received previous attempts of embolization), type I and II endoleak in 2 @entity1 , and sac growth without imaging evidence of endoleak in the other 10. After the infrarenal aorta was prepared (via a retroperitoneal access, whenever possible), the technique consisted of performing a banding of the neck with Teflon (DuPont, Wilmington, Del), a sacotomy to remove the @entity715 or the @entity3609 , or both, and then suturing all of the feeding vessels that were found. Proximal and distal fenestrations were performed to avoid sac repressurization. RESULTS: The semiconversion was performed after a mean of 74  months after the initial EVAR. The mean @entity439 size at the time of the EVAR was 6.0  cm (range, 5.0-9.5  cm), and the mean @entity439 size at the time of the semiconversion was 7.7  cm (range, 5.5-11.5  cm). The overall @entity439 size increase was 38%, and the average growth rate was 8.2% per year. One @entity1 had a stable @entity439 size but was treated because of an emergency condition. Technical success was 100%, with resolution of the endoleak and no perioperative @entity204 . Four @entity204 were registered at 12, 26, 30, and 60  months (mean follow-up, 42  months; range, 1-80  months). CONCLUSIONS: Graft salvage appears to be a valid option compared with open repair when considering treatment of persistent @entity1070 . This case series shows that semiconversion is a safe and effective treatment for otherwise untreatable @entity1070 .
