Abdominal Compartment Syndrome

Abdomen Anatomy

The abdomen extends from the thorax at the thoracic diaphragm to the pelvis (the pelvic brim). It is referred to as the abdominal cavity. It is bounded by the vertebrae, the abdominal muscles, the diaphragm and the pelvic floor. The abdominal cavity is a closed anatomical space. Contained within the abdominal cavity are the spleen, liver, kidneys, stomach, small intestines, large intestines, pancreas, aorta, gallbladder, diaphragm, the lower portion of the esophagus and the inferior vena cava.

Compartment Syndrome occurs when the pressure within a closed anatomic space (a compartment) becomes so elevated that capillary perfusion is compromised. Any closed anatomic space including the abdominal cavity is at risk of developing a compartment syndrome. Abdominal compartment syndrome is a clinical disease spectrum that results from increased intra-abdominal pressure (IAP) due to tissue edema or free fluid collecting in the abdominal cavity. Elevated pressure in the abdomen is referred to as intra-abdominal hypertension (IAH). Abdominal compartment syndrome is the end stage organ failure that occurs due to the pathophsiologic derangements that occur as a result of increasing intra-abdominal pressure. The end stage of undetected and untreated intra-abdominal hypertension is multi-system organ failure and patient death. 1

Intra-abdominal hypertension (IAH) is defined as the sustained or repeated pathologic elevation of intra-abdominal pressure (IAP) greater than or equal to 12 mmHG. Abdominal compartment syndrome is defined as a sustained IAP greater than 20 mmHG that is associated with the development of new organ dysfunction or failure. 2

Elevated intra-abdominal pressure can cause significant impairment of cardiac, pulmonary, renal, gastrointestinal, hepatic and central nervous function. The effects of IAH are not just limited to the intra-abdominal organs, but rather have an impact on every organ system in the body. 3

The sensitivity of both clinical judgment and physical examination have been demonstrated to be very poor in predicting a patient’s IAP. Early serial IAP measurements are therefore essential to both diagnosing the presence of IAH as well as guiding resuscitative therapy. While a variety of methods for IAP measurement have been described, intra-vesicular or bladder pressure has achieved the most widespread adoption worldwide due to its simplicity, minimal cost and low risk complications. Prolonged elevations in IAP’s of 10-20 mmHG can result in organ dysfunction and failure while pressures above 25mmHG are associated with potential mortality. 4

Immediate abdominal decompression should be performed in any patient who demonstrates significant elevations in IAP or evidence of ACS. In surgical patients, this is best achieved by either creating or reopening their laparotomy incision and applying a temporary abdominal closure. 5

Elevated IAP causes significant impairment of cardiac, pulmonary, renal, gastrointestinal and hepatic function with each organ demonstrating its own unique vulnerability. 6

Accurate and timely assessment of intra-abdominal pressure is crucial to the diagnosis and management of both intra-abdominal hypertension and abdominal compartment syndrome. As elevated IAP may occur insidiously and clinical examination is notoriously inaccurate in determining the presence of IAH, IAP measurements are an indispensable tool in the modern intensive care unit (ICU) setting. 7

Abdominal compartment syndrome is well recognized as a potential complication of laparotomy for trauma. It has also been reported after repair of large ventral hernias and may be anticipated in any case in which there is a loss of domain for abdominal organs. 8

Failure to diagnose Intra-Abdominal Hypertension leading to Abdominal Compartment Syndrome, multi-system organ failure and patient death following surgery of the Abdominal Cavity may constitute medical malpractice.

I met Diana Carnemolla and Howard S. Hershenhorn during the darkest time of our lives, when my husband was in a coma with very little chances to survive, due to a car accident. The compassion and professionalism that they showed myself and my family during such a difficult time combined with an incredible willingness to get the best results for us have shown us that we had made the absolute best choice. They not only fought extremely hard for what proved to be a very difficult case, but they also emotionally helped us through this incredible ordeal and have been a caring advocate for our family and our case. They got us the best results we could have expected given the circumstances and didn't give up when things got more challenging. We would absolutely recommend their Law Firm to handle the toughest of cases while providing such a great deal of personal support. Diana proved to be personally invested in our case ultimately seeking the best outcome for our family. We cannot thank them enough for what they have done for us. V.P.
