Description automatically generated
Acute renal failure is one of the possible complications of abdominal aortic aneurysm (AAA) repair, especially after open surgery. Acute renal failure is a sudden loss of kidney function that can cause fluid and electrolyte imbalance, acid-base disturbance, and uremic syndrome. Acute renal failure can occur due to several factors, such as hypoperfusion of the kidneys, atheroembolism, contrast-induced nephropathy, or ischemia-reperfusion injury12. The incidence of acute renal failure after AAA repair ranges from 2 to 25%, depending on the definition, the type of surgery, and the patient’s risk factors13. Acute renal failure is associated with increased morbidity, mortality, and length of hospital stay after AAA repair13.
Other complications of AAA repair include bleeding, infection, wound complications, graft-related complications, bowel ischemia, spinal cord ischemia, and cardiac, pulmonary, or neurological events124. Acute hepatic dysfunction, acute CVA, and atrial fibrillation are not specific complications of AAA repair, but they may occur in any major surgery or in patients with preexisting conditions.
