Which artery is most commonly injured in combat?

• A. The superficial femoral artery
• B. The brachial artery
• C. The carotid artery
• D. The popliteal artery

Answer: (A)

The key idea is that battlefield penetrating trauma frequently hits the thigh, where a large, main leg artery runs in a location that is readily struck. The superficial femoral artery is the main vessel in the thigh and lies along a trajectory that many gunshot or shrapnel paths follow, making it the artery most commonly injured in combat. Its size and prominence in the mid-thigh mean significant hemorrhage can occur quickly, so injuries here are more common than those to arteries in the neck or knee regions.

In contrast, the carotid artery sits in the neck protected by bone and soft tissues, the brachial artery is in the upper limb and less often on a typical combat trajectory, and the popliteal artery lies behind the knee, a less exposed area. Thus, while injuries to those vessels happen, they are less frequent than injuries to the superficial femoral artery.
