Objective: To evaluate the outcome after endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAA) in single center.

Patients and Methods: A total of 34 patients diagnosed with AAA treated by EVAR in University Hospital Centre Zagreb from June 2015 to September 2018 were followed-up and analyzed. There were 31/34 (91%) male and 3/34 (9%) female patients, with a mean age of 73.7±7.4 (range 55-87 years) in this study group. The primary outcome of the study was EVAR technical success (successful implantation) and all-cause mortality. Secondary endpoints were complications, length of stay in the ICU, and patient survival. Descriptive statistics were used to analyze the data.

Results: Mean diameter of treated AAAs was 62.1±12 mm (range 43-98 mm). Technical success rate were 94% (32/34) for implantation stent-graft system. In one patient we failed to perform implantation because of wide and angulated AAA neck, and one patient had external iliac artery rupture. In the follow-up period we recorded 2/32 (6%) deaths in the group of successfully implanted patients who were not related to AAA and EVAR procedure. Most common complication after successful EVAR procedure were endoleak type II in 11/32 (34%) patients, without the need for reintervention. Average length of stay in ICU was 1.08 day. In patients with EVAR mean survival was 19±11 months (range from 1 to 40 months) after procedure.

Conclusions: EVAR treatment for AAA is technically feasible and safe, with acceptable complications risks and with very short length stay in ICU after procedure. In order to prevent complications, extreme caution is needed when selecting patients who are anatomically suitable for the EVAR procedure. (1)
