The objective of this study was to evaluate the outcomes of patients undergoing explantation of aortic endografts. A review was conducted of consecutive explantations between 2002 and 2019. Patient demographics, operative data, and outcomes were abstracted from the electronic medical record. Univariable analysis is reported as means with standard deviation or percentages.
There were 108 patients who had explantation, 42 (INF) for infection and 66 for endoleak (END). Mean age was 71.9 years, and 95 were male. There was no difference between the groups in demographics. Increase in the excluded aneurysm sac occurred in 63 patients (97%) in this group, 33 (51%) from type I endoleaks, with aneurysmal degeneration of the suprarenal aorta in 37 (56%). Elective repair was done for approximately 75% of patients in both groups, with clamp position most often suprarenal or supramesenteric. In situ reconstructions were done in 95% of the patients in both groups. Explantation of aortic endovascular devices can be performed with low mortality but carries high complication rates, particularly for infected endografts, secondary to a systemic inflammatory response. Risk of procedure-related death is low at a mean of 21 months, regardless of the indication for explantation.
