Objective:
To evaluate the presentations, aetiologies, and outcomes (survival and morbidity) of patients who underwent abdominal aortic aneurysm (AAA) repair at a tertiary care centre in a low middle-income country (LMIC).
Study Design:
Case-series study. Place and Duration of the Study: Section of Vascular Surgery, Department of Surgery, The Aga Khan University Hospital, Karachi, Pakistan, from January 2000 till April 2022.
Methodology:
All patients who underwent elective open repair for AAA were identified using ICD coding 10. Patients' demographics, presentations, treatment options, and outcomes were recorded on a specially designed proforma. Outcomes were measured in terms of 30-day survival and perioperative complications.
Results:
Forty-two patients were included in the study. Thirty-nine (92.9%) of them were males. The mean age was 63.8 + 12.6 years. Thirty-four (81%) patients had an infrarenal aortic aneurysm. The average aneurysm diameter was 8.0 + 2.73 cm. The in-hospital survival rate was 95.2% whereas 2 (4.8%) patients had in-hospital mortality. Acute kidney injury (AKI) was the most common complication, seen in 5 (11.9%) patients. Adverse outcomes were seen more in diabetic patients whereas increased incidence of AKI was noted in operations with supra-renal clamping (p<0.05).
Conclusion:
Most patients presented with symptoms and large aneurysm size. Open AAA repair was performed safely with 4.8% in-hospital mortality and acceptable morbidity in the LMIC setting.
Key Words:
Abdominal aortic aneurysm repair, Low middle-income country.
