Management of Non-Infectious Aneurisms of the Sub-Kydney Abdominal Aorta at the CHU/JRA

Abstract

Introduction: The aim of this study was to describe the principle of the management for non-infectious aneurysm of the sub-kidney abdominal aorta at the university teaching hospital/JRA Ampefiloha.
 Materials and methods: It was a retrospective, descriptive study conducted at cardiovascular surgery department of the university teaching hospital/JRA Ampefiloha, for a period of 14 years old (January 2005 to December 2019), including all patients who had an non-infectious aneurysm of the subrenal abdominal aorta at the CHU/JRA Ampefiloha operated on or not.
 Results: Sixty-one cases were included, with an mean age of 61.71 years old (from 16 to 82 years old), a male predominance (sex ratio-1.34), high blood pressure, dyslipidemia, active smoking and physical inactivity were the predominant risk factors. The circumstances of discovery were often abdominal pain (52.45%) and a flapping abdominal mass (47.54%). Aortic doppler ultrasound and/or CT angiography allowed the diagnosis and describe the type of aneurysm. Most of them was fusiform in 49 cases (80.32%) and sacciform in 12 cases (19.67%), the majority of which had a diameter of between 50 and 60 mm (36.06%). Thirty-nine patients were operated on (63.93%). Conventional surgery with the flattening of the aneurysm followed by a replacement with a prosthetic graft was our reference technique. Postoperative development was favorable in 82.05% of cases. The mortality rate was 6.56%.
 Conclusion: The hospital frequency of an abdominal aortic aneurysm was 1.53% at the university teaching hospital/JRA Ampefiloha. Conventional surgery was our reference technique, saving the lives of our patients.

Management of abdominal aortic aneurysm in a resource-limited context: About one case repaired on at Katana Referral Hospital, South Kivu, in the Democratic Republic of Congo.

“…Aortic aneurysm is defined as a permanent segmental dilatation, greater than 50% of the normal diameter of the proximal aortic segment 1 . This dilatation can be baggy or spindle 2 .…”

“…Aortic aneurysms are important causes of mortality, in developed countries such as in the United States of America where, arterial aneurysms and their ruptures were responsible for approximately 15,000 deaths per year in 2013 and this could be just the tip of the iceberg 1 . Studies have shown that the incidence of ruptured abdominal aortic aneurysms (AAA) in sudden deaths is 4 to 5%.…”
