Abstract

Objectives: To study the one-year results of EVAR for infrarenal AAA patients in Rajavithi Hospital.

Methods: This study conducted a retrospective chart review of all patients with infrarenal AAA who underwent EVAR between January 2017 and February 2021. Medical records were analyzed for demographic data, anatomic features of AAA, procedural details, and 30-day and 1-year outcomes. The primary outcomes were technical success and clinical success at one-year follow-up. Secondary outcomes included perioperative complications, mortality, stent-graft-related complications, and secondary interventions.

Results: This study included 43 patients (32 men) with a mean age of 72 ± 8.4 years. Successful primary technical success was achieved in 40 patients (93%). The mean operative time was 150.8 ± 58 min, and the median estimated blood loss was 150 ml. The median hospital stay was eight days. Major complications occurred in 9 (20.9%) patients, including 1 myocardial infarction, 1 congestive heart failure, 2 cardiac arrhythmias, 3 pneumonia-related respiratory failures, 2 ischemic colitis, and 2 renal failures requiring hemodialysis. The 30-day mortality was 4.7% (2 patients; one with infected AAA with aortoenteric fistula, and one with pneumonia and multisystem organ failure. A 1-year overall mortality was 16.3%, and AAA-related mortality was 2.3%. A 1-year clinical success rate of 91.4% was observed in 32 out of 35 patients. No cases of stent-graft thrombosis, stent-graft infection, ruptured AAA, open conversion, or type III or IV endoleak were documented in the study.

Conclusion: EVAR can be successfully performed at Rajavithi Hospital with high success and low AAA-related mortality rate. However, it is crucial to emphasize the importance of surveillance to promptly detect and effectively treat any potential complications that may arise.
