A patient complains of having pain with repeated movements of his thumb (claudication). His physician performs the Allen test and finds an insufficiency of the radial aery. Which of the following conditions would be a result of the radial aery stenosis?,
Correct Answer: A marked decrease in the blood flow in the princeps pollicis aery
Description: The Radial aery divides into the Princeps pollicis aery and the deep palmar aerial arch. Thus, stenosis of the radial aery results in a decreased blood flow in the princeps pollicis aery. Superficial palmar aerial arch is formed primarily by the ulnar aery, which passes superficial to the flexor retinaculum. Extensor compament of the forearm receives blood from the posterior interosseous aery, which arises from the common interosseous branch of the ulnar aery.
