Background: Currently the preferred treatment method for
abdominal aortic aneurysm (AAA) is endovascular aneurysm
repair (EVAR) due to benefits associatedwith aminimally invasive
procedure over open repair. Limitations of EVAR include limited
applicability, higher rates of endoleak and reintervention. A novel
technique aiming to overcome these limitations is endovascular
sealing (EVAS), using the Nellix device.
Aims: Retrospectiveserviceevaluationwasperformedto:evaluate
outcomes of all patients treated with EVAS at Southampton
General Hospital (SGH). Explore any difference in outcome
between EVAS patients treated within the Nellix instructions for
use (IFU) versus those outside it.
Methods: Data including aneurysm morphology and
demographics from all patients treated with EVAS at SGH was
collected retrospectively from patient records and computed
tomography scans. This was utilized for assessment of survival
at 30 days and 1 year, and occurrence of aneurysm related
complications or reintervention post-EVAS.
Results: 1/26 study patients was female. Mean age and baseline
eGFR was 76.9±6 and 62.7±21.4 respectively. 11/26 patients
were treated off-IFU. No deaths occurred within 30 days post-
operatively. Overall, 5 mortalities occurred by 1 year post-op
- none were aneurysm related. 3/5 deaths occurred in patients
treated off-IFU. Difference in survival between patients treated
within vs. off-IFU was not statistically significant (p=0.176; log-
rank, p=0.260; generalized Wilcoxon). Three patients developed
aneurysm related complications, however only one reintervention
was performed.
Conclusion: Mortality post-EVAS was higher than expected - may
be reflective of high risk patients chosen for a novel technique
due to unsuitability for other treatment modalities. Endoleak and
reintervention rates are low in line with other centers. Longitudinal
studies evaluating long-term outcomes post-EVAS are needed to
demonstrate its role in the treatment of AAAs.
