Early results of open surgical repair of infrarenal abdominal aortic aneurysms with silver coated grafts at Thai Binh Provincial General Hospital

Abstract

Objective
 Open surgical abdominal aortic repair, involving the excision of dilated area and placement of a synthetic graft is a common, major operation done to treat an aortic aneurysm. This procedure, however, is a challenge for cardiovascular surgeons because of its postoperative mortality and complications. The objective of this research is to study the prognostic factors and early results of open surgical repair (OSR) for abdominal aortic aneurysms (AAA), beginning below the renal arteries.
 Methods
 This is a descriptive retrospective study on patients with infrarenal AAA, who underwent OSR to replace the aneurysmal sac with a silver coated synthetic graft at Thai Binh Provincial General Hospital from June 2019 to June 2021
 Results
 40 cases including 28 males and 12 females were eligible for our study. The average age of the studied groups was 68.7 ± 8.95 years old. Common observed clinical symptoms of this demographic included hypertension, lipid metabolism disorders. Most of the aneurysm sacs were rhomboid-shaped with the diameter and the neck length ranged of 5-8 cm and 1.8 ± 0.75cm respectively. The success rate of the procedure was 100%. Pneumonia was the most commonly seen postoperative complication. There was no complication related to the grafts. 02 deaths were reported after surgery due to multi-organ failure. GA (Glasgow Aneurysm) score was excellent and the Hardman score was a good predictor of mortality.
 Conclusions: 
 OSR was a common treatment method for ruptured AAA and AAA that can not be indicated with endovascular placement of an aortic stent graft (EVAR). It was crucial to take prognostic factors into consideration so as to avoid postoperative complications.
