What complication is associated with AAA repair that involves fluid accumulation in the abdominal compartment?

The identified complication is abdominal compartment syndrome, which can result from fluid accumulation in the abdominal cavity after an abdominal aortic aneurysm (AAA) repair. This condition occurs when increased pressure within the abdominal cavity compromises organ function and perfusion.

After AAA repair, various factors can contribute to fluid accumulation, such as surgical trauma, bleeding, or the administration of intravenous fluids. The accumulated fluid increases intra-abdominal pressure, which can lead to physiological changes that may affect respiratory, cardiovascular, and renal function. Symptoms often include abdominal pain, nausea, vomiting, and decreased urine output, all indicative of organ dysfunction due to the pressure exerted on intra-abdominal structures.

Recognizing and treating abdominal compartment syndrome promptly is crucial in the postoperative management of patients following AAA repair to prevent severe complications, including organ failure.
