Endovascular repair was associated with a 21.62% incidence of endoleaks, with patients experiencing endoleaks having significantly larger aneurysms (7.06 vs 6.07 cm, p=0.007), longer ICU stays (p=0.002), and higher hypertension prevalence (83.33% vs 62.07%, p=0.050).

What clinical and procedural characteristics are associated with the development of endoleaks following EVAR for infrarenal AAA?
Larger baseline aneurysm size and hypertension are significant risk factors for developing endoleaks, particularly Type II, following EVAR for infrarenal AAA.
Absolute Event Rate: 21.62% vs 78.38%
p-value: p=0.007 for aneurysm size; p=0.002 for ICU stay; p=0.050 for hypertension; p<0.001 for types 1 and 2 endoleak; p=0.006 for 6-month follow-up endoleak presence
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.

Endovascular aneurysm repair (EVAR) vs. No endoleak after EVAR was evaluated on Occurrence of endoleaks post-EVAR and associated clinical and procedural characteristics (p=p=0.007 for aneurysm size; p=0.002 for ICU stay; p=0.050 for hypertension; p<0.001 for types 1 and 2 endoleak; p=0.006 for 6-month follow-up endoleak presence). Endovascular repair was associated with a 21.62% incidence of endoleaks, with patients experiencing endoleaks having significantly larger aneurysms (7.06 vs 6.07 cm, p=0.007), longer ICU stays (p=0.002), and higher hypertension prevalence (83.33% vs 62.07%, p=0.050).
