ABSTRACT
OBJECTIVE:
Reintervention after endovascular aortic aneurysm repair is common. However, their frequency and impact on mortality after physician-modified endografts (PMEGs) is unknown. This study aims to describe reinterventions after PMEG for treatment of juxtarenal aneurysms and their effect on survival.METHODS:
Data from a prospective investigational device exemption clinical trial (Identifier #NCT01538056) from 2011 to 2022 were used. Reinterventions after PMEG were categorized as open or percutaneous and major or minor by Society for Vascular Surgery reporting standards and as high or low magnitude based on physiologic impact. Reinterventions were also categorized by timing, based on whether they occurred within 30 days of PMEG as well as within 1 week of PMEG. Survival was compared between patients who did and did not undergo reintervention and between reintervention subcategories.RESULTS:
A total of 170 patients underwent PMEG, 50 (29%) of whom underwent a total of 91 reinterventions (mean reinterventions/patient, 1.8). Freedom from reintervention was 84% at 1 year and 60% at 5 years. Reinterventions were most often percutaneous (80%), minor (55%), and low magnitude (77%), and the most common reintervention was renal stenting (26%). There were 10 early reinterventions within 1 week of PMEG. Two aortic-related mortalities occurred after reintervention. There were no differences in survival between patients who underwent reintervention and those who did not. However, survival differed based on the timing of reintervention. After adjusted analysis, reintervention within one week of PMEG was associated with an increased risk of mortality both compared with late reintervention (hazard ratio, 11.1; 95% confidence interval, 2.7-46.5) and no reintervention (hazard ratio, 5.2; 95% confidence interval, 1.6-16.8).CONCLUSIONS:
Reinterventions after PMEG were most commonly percutaneous, minor, and low magnitude procedures, and non-detrimental to long-term survival. However, early reinterventions were associated with increased mortality risk. These data suggest that a modest frequency of reinterventions should be expected after PMEG, emphasizing the critical importance of lifelong surveillance.Palavras-chave
