The abdominal compartment syndrome: a complication with many faces

Area of Science:

• Critical care medicine
• Surgical pathophysiology
• Intra-abdominal hypertension management

Background:

• Abdominal compartment syndrome (ACS) is receiving renewed attention, yet controversies persist regarding its pathophysiology and treatment.
• Understanding the mechanisms and identifying optimal therapeutic strategies for ACS remain critical challenges in critical care.

Observation:

• ACS can arise from various clinical disorders, significantly impacting cardiovascular, pulmonary, and renal systems.
• Intra-abdominal pressure (IAP) can be reliably monitored via intravesical pressure measurements.
• While surgical decompression (laparotomy) is the accepted treatment, precise indications based on clinical signs and pressure remain debated.

Findings:

• No universal threshold for intra-abdominal pressure reliably predicts ACS development or dictates surgical intervention.
• Intravesical pressure of 25 mmHg or higher, combined with organ dysfunction (hypotension, renal or respiratory failure), suggests the need for surgical decompression.
• The exact mechanisms leading to ACS in susceptible individuals are not fully elucidated.

Implications:

• Early recognition and intervention are crucial for improving outcomes in patients with ACS.
• Standardized guidelines for surgical intervention based on objective pressure measurements and clinical status are needed.
• Further clinical trials are essential to refine diagnostic criteria and therapeutic algorithms for abdominal compartment syndrome.
