Predictors of 30-day Postoperative Outcome After Elective EVAR

Predictors of 30-day Postoperative Outcome After Elective Endovascular Abdominal Aortic Aneurysm Repair

This study investigated the 30-day postoperative outcome after elective EVAR and the role of possible predictors among patients' baseline characteristics

The study included 322 consecutive AAA patients treated electively with EVAR from March 2016 to February 2019 at a tertiary referral center.

Early follow-up with clinical and laboratory evaluation took place at the 30rd day post-operatively. Any adverse event, such as major adverse cardiovascular events (MACE), post-implantation syndrome (PIS), acute kidney injury (AKI), and deaths of any cause were recorded.

Inclusion Criteria:

• Only patients managed with EVAR using standard bifurcated devices in elective setting were included.

Exclusion Criteria:

• Patients treated for ruptured, symptomatic, inflammatory or infectious AAA were excluded. Furthermore, any patient needing complex endovascular repair of the proximal landing zone was considered ineligible. Additional exclusion criteria were the presence of any trauma or surgery within two months before EVAR, any autoimmune or systemic inflammatory disease and any malignancy. Of note, any patient with clinical or laboratory signs of infection before the scheduled operation was not offered an EVAR until a complete resolution of the infection was confirmed via a clinical, laboratory and/or imaging evaluation.
