Introduction: Endoleak is the main cause for reintervention after endovascular aortic repair. Some patientis need prolonged oral anticoagulation, which may increase the incidence of postoperative endoleaks.

Objectives: Our objective was to determine whether postoperative oral anticoagulation has an impact on the incidence of endoleaks.

Methods: This retrospective analysis included all patientis with endovascular treatment of abdominal aortic aneurysm at our center between 2009 and 2014. Two groups of patientis were determined according to the need for oral anticoagulation. Aortic-related mortality, survival free from reinterventions, any endoleak and non-type II endoleaks, survival free of the composite endpoint of mortality associated with the aorta, reinterventions and endoleaks, and reduction of aneurysmal sac diameter was compared between both groups.Resultis: Among 341 treated patientis, 33 (9.67%) were anticoagulated. There were no differences between the two groups in terms of aorta-related mortality (2.59% vs. 3.03%, p=ns), reintervention-free survival (84.04% vs. 86.2%; p=ns), any endoleak- free survival (82% vs. 89%, p=0.81) or non-type II endoleak-free survival (88% vs. 88%, p=0.52). Similarly, no significant differences were found when analyzing the composite endpoint-free survival (80% vs. 85%, p=ns). The average reduction of aneurysmal sac diameter was 5.19 mm and 3.51 mm (p=0.2).

Conclusions: No difference was registered in any of the resultis analyzed. Postoperative oral anticoagulation had no impact on the resultis of endovascular aortic treatment.
