A 53-year-old man was admitted to the emergency room unconscious. Apparently he had attempted to cross the road on crutches when he was hit on the side of the head by a car. On examination he was found to have a large swelling over the left side of the head in the temporal region. The neurologic findings included a rightsided hemiplegia. A lateral radiograph of the skull showed a fracture line across the region of the lower anterior end of the right parietal bone.
-Name the artery that was most likely to have been damaged in the accident.

Question

Quizplus · Accepted Answer

The anterior division of the middle meningeal artery is the most common artery to be damaged after a blow to the lateral side of the head.
The arterial or venous injury is especially liable to occur if the artery and vein enter a bony canal in the region of the anterior inferior angle of the parietal bone (see CD Fig. 6-1)
