What complication is associated with Abdominal Compartment Syndrome following AAA repair?

Abdominal Compartment Syndrome (ACS) is a condition that arises when there is increased intra-abdominal pressure, which can occur as a complication after an abdominal aortic aneurysm (AAA) repair. This elevated pressure can lead to a systemic inflammatory response, resulting in widespread hemodynamic compromise throughout the body.

In the context of AAA repair, several factors can contribute to the development of ACS, including fluid shifts due to surgical manipulation, blood loss, and underlying vascular transformation. The systemic inflammatory response can cause issues such as reduced venous return, decreased cardiac output, and impaired organ perfusion, leading to complications in multiple organ systems, particularly the renal system, gastrointestinal tract, and circulatory system.

Therefore, the correct answer highlights the serious nature of the systemic effects of increased intra-abdominal pressure following AAA repair, which can lead to significant hemodynamic instability. This understanding is crucial in the management of patients post-surgery to identify and address potential complications early on.
