“…Compassionate proponents for EVAR have tried to repair failing endografts with numerous endovascular maintenance procedures in-stead of taking the risk of conversion to open surgery. When endovascular procedures have failed or are not possible, some patients have been left under mere observation (12)(13)(14)(15)(16).…”

Background: The aim of the study was to assess the long term results of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms at the Helsinki University Central Hospital 1996-2004 with a special emphasis on elective conversion procedures and their outcome.Methods: Treatment results and follow-up data of all 110 elective EVAR procedures performed in our institution were gathered prospectively and evaluated.Results: Conversion to open surgery was performed in 23 (21 %) of 110 EVAR patients. 30-day mortality after elective stent-graft deployment was 0%as it was also on elective conversions (n =20). Secondary elective conversions were performed due to infection in two and after failing stent-graft treatment in 12 patients. Six of the conversions were performed primarily. Three urgent conversions (3 % overall) were performed: two of these patients died, corresponding to an overall mortality of 9 % (2/23) in all conversions. Five-year aneurysm-related mortality after EVAR among patients with elective conversion was 0 % and 19 % in patients with secondary procedures other than elective conversions.Conclusions: As conversions seem to be hazardous only when performed in urgent situations, elective conversion could be an alternative treatment method in complex failing first-generation stent-grafts as it may reduce mortality associated with urgent conversions or repeated attempts to maintain graft integrity with endovascular procedures.

“…39 Secondary interventions are typically performed when the aneurysm sac has become repressurized because of incomplete exclusion of blood flow from the sac. The term "endoleak" was created to describe this complication in 1996, 40 and a classification scheme has been adopted [41][42][43] (Figure 3). Type I and type III endoleaks are treated with immediate intervention to halt perigraft flow or flow between modular components.…”

“…However, there are reports of endotension patients who have undergone surgical conversion for aneurysm enlargement without any evidence of blood inside the aneurysm sac [20]. Pressure may remain high in the excluded aneurysm sac due to transmission of the pressure through thrombus at or around the ends of attachment zones of the prothesis [21,22]. This has been particularly associated with angulation of the proximal aspect of the graft [20].…”
