A 36-year-old man presents with blunt abdominal trauma and hemodynamic instability (BP 88/52, HR 128, RR 22). CT imaging reveals hepatic laceration with active bleeding. During emergency laparotomy, the surgeon applies compression to the free edge of the lesser omentum to temporarily control hemorrhage. Vital signs improve with manual compression. Which of the following structures is being clamped? (Hemoglobin 7.2 g/dL; no peritoneal perforation noted.)
- A)Splenorenal ligament
- B)Gastrosplenic ligament
- C)Falciform ligament
- D)Hepatogastric ligament
- E)Hepatoduodenal ligamentGABARITO
