Management of Grade 3 Liver Laceration with Active Bleeding

Initial Assessment and Management

The World Society of Emergency Surgery recommends that hemodynamically stable patients with Grade 3 liver laceration and active bleeding undergo angioembolization as the primary intervention, while hemodynamically unstable patients require immediate operative management with damage control surgery 1, 2
Grade 3 liver lacerations are classified as moderate when hemodynamically stable, but escalate to severe if hemodynamically unstable, changing the management approach 3, 2
Hemodynamic instability is defined as blood pressure <90 mmHg with heart rate >120 bpm, evidence of skin vasoconstriction, altered level of consciousness, or shortness of breath 3, 4

For hemodynamically stable patients with Grade 3 liver laceration and active bleeding on CT, proceed directly to angiography with embolization as the primary intervention, which is the definitive treatment for arterial bleeding in stable patients 1, 2
Angioembolization is effective in 80-90% of cases for stopping arterial bleeding, but carries a risk of hepatic necrosis (5-10%) and sepsis, requiring close monitoring for fever, leukocytosis, and abdominal pain in subsequent days 1

For hemodynamically unstable patients, proceed immediately to operative management without additional imaging, as mortality increases with every minute of delay 1, 2
Initiate massive transfusion protocol immediately with 1:1:1 ratio of packed red blood cells, fresh frozen plasma, and platelets to reverse the lethal triad of hypothermia, acidosis, and coagulopathy 1, 5
The surgical approach follows a hierarchical algorithm, including manual compression of the liver, Pringle maneuver, perihepatic packing, and ligation of bleeding vessels within the liver substance 1, 5, 6

CT follow-up at 48-72 hours for Grade 3 injuries managed nonoperatively to assess hematoma evolution and identify delayed complications (biloma, abscess, pseudoaneurysm) 6, 2
Counsel patients to avoid strenuous activity for 3-4 months and return immediately for increasing abdominal pain, lightheadedness, nausea, or vomiting 6
