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.
