Question

A 20-year-old man is brought to the emergency department with a gunshot wound to the abdomen. His blood pressure is 70 systolic and his heart rate is 140 beats per minute (bpm). He is taken directly to the operating room for an exploratory laparotomy. A large, actively bleeding liver laceration is found. A pringle maneuver is performed as part of the procedure to control his bleeding. The Pringle maneuver compresses which structures?

(A) Portal vein, hepatic vein, and hepatic artery
(B) Portal vein, hepatic artery, and cystic artery
(C) Portal vein and hepatic artery
(D) Portal vein, hepatic artery, and CBD
(E) Cystic artery, cystic duct, and CBD

Answer 1

The Pringle maneuver compresses the portal vein and hepatic artery to control bleeding from the liver during surgery.

Step-by-step explanation:

The Pringle maneuver is a surgical technique used to control bleeding from the liver. It involves clamping the hepatoduodenal ligament to compress the hepatic artery and hepatic portal vein, but not the hepatic veins, which drain blood from the liver into the inferior vena cava. Therefore, the structures compressed during the Pringle maneuver are the portal vein and hepatic artery (C). This maneuver temporarily stops the inflow of blood to the liver, reducing bleeding and allowing the surgeon to work on repairing the liver injury.
