Purpose: Endoanchor fixation is an effective adjunct in preventing type 1a endoleaks and graft migration in endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR). Methodology: The study included consecutive patients who underwent endoanchor fixation for thoracic or abdominal endovascular repair between June 2019 and Dec 2024. Primary placement was defined as endoanchor fixation at the time of the index procedure, while secondary placement was defined as an additional procedure to treat sac expansion from an ongoing type 1 leak. Maximal aneurysmal diameter was measured pre and post operatively. Patients were followed up to monitor for aneurysmal re-expansion, complications (including endoleaks), and need for reintervention. All patients were followed up clinically and with imaging. Results: There were 30 patients (7 Females) with a median (range) age 80 (44-91) years. The median (range) follow up was 20 (2-59) months. Of the 30 patients, 25 (83%) had abdominal aortic interventions. The median preoperative and postoperative maximal aneurysm diameters were 60mm and 59.5mm respectively in the primary intervention group, and 69.5mm and 67mm in the secondary intervention group. There were 2 patients in each group that required unplanned aortic re-intervention (two for a type 1a endoleaks, and two type 2 endoleak). There were no endoanchor mislodgments or fractures observed. Conclusion: Endoanchor fixation during EVAR and TEVAR in challenging proximal landing zones could improve the durability of endovascular aortic repair. Further follow up is required to define the role of this additional endovascular armamentarium.
