Massive Ascites Causing Presumed Abdominal Compartment Syndrome During Open Heart Surgery With Cardiopulmonary Bypass

Abstract

Abdominal compartment syndrome (ACS) is a potentially fatal condition and a known cause of morbidity and mortality in critically ill patients. It can be primary, due to abdominal trauma and/or surgical procedures, or secondary, due to excessive abdominal fluid and/or bowel edema. Intra-abdominal hypertension (IAH) is defined as intra-abdominal pressure (IAP) greater than 12 mm Hg. ACS occurs when increased IAP results in organ dysfunction. Although IAPs are known to increase in cardiac surgery, ACS is uncommon, and reports are limited in the literature. We describe a fatal case of presumed ACS during an aortic valve and root replacement with coronary artery bypass grafting (CABG).
