Abstract

Objective: To evaluate the surgical outcomes of open repair for infrarenal abdominal aortic aneurysm (AAA) using a midline transperitoneal approach and prosthetic graft replacement. Methods: A retrospective descriptive study was conducted on patients who underwent open surgical repair of infrarenal AAA via a transperitoneal approach at the University Medical Center Ho Chi Minh City from January 2015 to March 2023. Data collected included patient characteristics, surgical details, postoperative complications, and early outcomes. Results: The study included 53 patients, with a mean age of 67.94 ± 9.52 years, of whom 75.47% were male. Hypertension was present in 75.47% of patients, coronary artery disease in 32.08%, and diabetes mellitus in 18.87%. The mean operative time was 223.0 ± 55.5 minutes, with a mean aortic clamp time of 46.6 ± 24.7 minutes and an average blood loss of 479.2 ± 293.5 ml. The perioperative mortality rate was 3.77%. Early complications included acute kidney injury (18.87%), respiratory complications (13.21%), and gastrointestinal complications (16.98%). Late incisional hernia occurred in 7.5% of cases. Conclusion: Open repair via the transperitoneal approach remains an effective and safe treatment for infrarenal AAA. However, careful postoperative monitoring and individualized surgical planning are necessary to optimize patient outcomes.
