AB Endoleak (EL) represents the most common complication following endovascular abdominal aortic aneurysm repair (EVAR). Unfortunately, the long-term results of EVAR and its durability have been questioned, and EL are variably associated with a risk of late failure. The aim of this retrospective study was to identify risk factors for this complication of aneurysm-endograft complex in patients who underwent EVAR. A group of 104 consecutive patients (99 men, 5 women; median age, 74 years; range, 50-89 years) were enrolled in the study. Both preoperative and follow-up imaging studies were obtained using helical computed tomography scanning at 1, 6, 12, 24, 36 months after EVAR and blindly reviewed by a surgeon and a radiologist. Twenty-seven (25.9%) patients developed EL during follow-up, of which 10 (37%) were primary (<30 days from EVAR), and 17 (63%) were secondary EL. Age and smoking did not affect the EL onset, while a body mass index >25 and a history or presence of arterial hypertension represented significant (p<0.05) risk factors. Moreover, both greatest diameter and maximum length of the aneurysm were significantly higher (p<0.01) in patients who developed EL. No relationship was found with the anatomical features of the aortic neck (i.e. length and diameter), and between the initial size of the aneurysm and the dimension at the time of EL. In conclusion, in our study, being overweight, arterial hypertension and the initial size of the aneurysm represent risk factors for EL development.
