Abstract: |
Background: Elective open repair (OR) and endovascular aneurysm repair
(EVAR) are the 2 methods of infra-renal abdominal aortic aneurysm (AAA)
repair. Each method has advantages and disadvantages. Aim of study was to
compare both methods.
Patients and methods: Prospective study was conducted at vascular
surgery departments, Zagazig University Hospitals, Egypt and Alnoor
Specialist Hospital, Makkah, Saudi Arabia from February 2015 to January
2020. Included patients were with asymptomatic AAA with diameter
≥5.5cm or symptomatic. Patients underwent computerized tomographic
angiography, echocardiogram, cardiac and chest consultation.
Results: 14 patients underwent OR and 9 underwent EVAR. No statistically
significant difference between both groups regarding demographics or
aneurysm characteristics. In OR group mean age was 65.54±4.44 years and
mean aneurysm maximum diameter was 6.92±0.55 cm, while in EVAR
group mean age was 67.03±5.31years and mean aneurysm maximum
diameter was 7.1±0.3cm. EVAR group had statistically significant less
duration of procedure (p<0.001), blood loss (p<0.001), blood transfusions
(p=0.003), less ICU (p<0.001) and hospital stays (p<0.001).
Conclusion: EVAR group had statistically significant less duration of
procedure, blood loss, blood transfusions, ICU and hospital stay than OR
group. No statistically significant difference between 2 groups regarding
mortality. Second interventions were more in EVAR but did not reach
statistical significance. Our study was limited by small number of patients
and only 2 years follow-up. However, there is an evolving concept in
literature that in low-risk patients, both procedures have nearly similar
results with less reinterventions in OR, but for high risk patients EVAR may
be preferred. So, selection between EVAR and OR should be tailored for
each patient according to surgical risk, life span, aneurysm anatomy and
patient choice
