Short-term Outcomes of Elective Abdominal Aortic Aneurysm Repair.

Abstract

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). 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. 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. 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). 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.
