Background: To evaluate the aneurysm-related complications and device issues in patients who underwent partial endograft explantation during late conversion of endovascular aneurysm repair (EVAR) to open repair.
Methods: A retrospective analysis was performed on patients who had partially explanted endografts during late conversion between 1999 and 2012. Medical records were reviewed for patient demographics, subsequent operations, and aneurysm-related complications. Postoperative abdominal X-ray films and computed tomography scans were analyzed for endograft migration, component separation, device fracture, and arterial growth or aneurysm issues.
Results: Between 1999 and 2012, 22 patients had late conversion after EVAR with portions of the device left in situ. Five of the partially removed devices were Zenith, 6 Talent, 5 Ancure, 3 AneuRx, 2 Excluder endografts, and 1 Cook Aorto uni-iliac (AUI) graft. There were 4 in hospital mortalities. There were no graft migrations, component separations, device fractures, new aneurysmal degeneration, or ruptures with a median follow-up of 26.5 months.
Conclusions: Partial endograft removal during late conversion is not associated with complications from the remaining device pieces during follow-up. We recommend further study of this patient population.
