ABSTRACT
Objective: The current study aimed to explore endoleaks events post-EVAR, and find relations with clinical and
procedure characteristics from medical records. Methods: A retrospective design analyzed patients undergoing
EVAR for AAA. Study was conducted in King Hussein Medical Center (KHMC). Data was collected for
demographics, surgical, and clinical variables. Data collection started from January 2019 till August 2025.
Results: The participants consisted of 111 subjects with an average age of 72.03 ± 9.29 years; 92.79 were males,
29.73 had diabetes mellitus, 66.67 were hypertensive, and 62.16 were smokers. The endoleak group (n=241) had a
greater aneurysm size than those without (n=871) (7.06 ± 1.90 vs 6.07 ± 1.00 cm; p=0.007). The longer hospital
stays were more prevalent among the participants with endoleak. The prevalence of hypertension was higher
among the endoleak group (83.33% vs 62.07; p=0.050). Endoleak types were exclusively present in the endoleak
group: Type 1 (54.17%; p<0.001), Type 2 (58.33%; p<0.001), and Type 3 (12.50%; p=0.009). Follow-up
endoleaks at 6 months were significantly more common in those with baseline endoleak (17.39% vs 0%; p=0.006).
Conclusion: We studied in this cohort the presentation of these endoleaks in relation to patient profiles and
procedural details. Bigger size aneurysms and longer stays at the ICU were reported in patients who experienced
endoleaks. In patients who developed endoleaks, hypertension was an important risk factor presented in these
patients. Type II endoleaks were the most common seen type, as well as follow-up endoleaks at 6 months were
more common in those with baseline endoleak.
