Objectives: Endovascular aneurysm repair (EVAR) is a
widely used modality in the treatment of abdominal aortic aneurysms (AAA).
Siena EVAR and St.George Vascular Institute (SGVI) scores are risk scores to
predict possible EVAR related reinterventions. This study was aimed to validate
the risk scores and compare the predictivity of the scoring systems for
hospital cost-effectiveness in our population.Materials and Methods: 39 patients with unruptured
infrarenal AAA, including both elective and non-elective admissions which had a
follow-up period from at least 6 months are included in our study. Siena EVAR
score and SGVI score are calculated. The relation of the complications
(adjuncts at the index operation, reinterventions during follow up), costs
(index procedure and overall), aneurysm related mortality are compared among
the risk groups. Results: In our study, SGVI score had a predictivity
among high and low-risk groups involving reinterventions during follow up, cost
on index operation and mortality (P < 0.05). Siena EVAR score had no
significant predictivity (p > 0.05).
Conclusion: A high-risk value in SGVI score must warn
the surgeon to reassess the treatment option for AAA. If EVAR is indicated the health care providers
and assurance system can count on a higher cost on index operation, a higher
risk of reintervention and mortality during long term follow up.
