In a hunting accident, an arrow pierces the mid-calf of a hunter. A major artery is lacerated in the posterior leg, and you notice that the sole of his foot is cold and pale. The dorsum of the foot is warm and normally colored. The artery that seems to be injured is the:
A. fibular artery
B. posterior tibial artery
C. femoral artery
D. popliteal artery
E. medial plantar artery
B. posterior tibial artery
If the femoral artery is occluded at the beginning of the adductor canal, which artery could help provide viability to the leg through collateral circulation?
A. Descending branch of the lateral circumflex femoral
B. Descending genicular
C. First perforating branch of the deep femoral
D. Medial circumflex femoral
E. Obturator
A. Descending branch of the lateral circumflex femoral

The victim of multiple shrapnel wounds to the upper limb must have his forearm amputated at midlength. Because of concomitant damage in the patient’s arm, the surgeon must ligate the main artery at some point. The best chance of saving collateral circulation to the stump of the forearm would be when the ligature is placed just below which of the following?
A. Beginning of brachial artery
B. Origin of the deep brachial artery
C. Origin of the superior ulnar collateral artery
D. Origin of the inferior ulnar collateral artery
E. Bifurcation of the brachial artery
E. Bifurcation of the brachial artery
You are in the emergency room when a patient is brought in, the loser in a street fight. He has received a stab wound about 1.5 cm long in the right side of the chest about 1.5 cm below and 1 cm medial to the coracoid process of the scapula. He has lost a lot of bright red blood from a large (approx. 1.2 cm in diameter) severed artery found deep at this location. Intravenous fluids are immediately administered and a surgeon is called in to repair the artery. He begins by making an incision through the skin and subcutaneous tissue just below the clavicle, then cuts the clavicular head of the pectoralis major muscle and retracts it downward to obtain sufficient exposure of the area. He next encounters a partially severed muscle running downward and medially from the coracoid process. He divides the remaining fibers of the muscle and has you retract it downward. This exposes a bloody fat-filled space full of vessels and nerves. The surgeon next encounters a large (about 2 cm in diameter) horizontally running vein, fortunately intact, which is also retracted downward. This exposes the damaged artery. He knows that the cords of the brachial plexus are closely associated with this artery, so he carefully retracts one found superolateral and one found inferomedial to the artery and then proceeds to repair the artery itself and close the wound. The large artery that was severed was the:
A. axillary
B. brachial
C. radial
D. subscapular
E. suprascapular
A. axillary
Which of the following is not a direct branch of the axillary artery?
A. anterior circumflex humeral
B. posterior circumflex humeral
C. thoracoacromial
D. thoracodorsal
E. subscapular
D. thoracodorsal
In the process of escaping from T. rex in Jurassic Park the heroine punctures the skin on the medial side of her wrist on a spiny bush. A few days later, due to the toxin, an infection is seen spreading up the medial side of her arm along the large cutaneous vein extending from the dorsum of her hand to the medial side of her arm. The vein involved is the:
A. basilic
B. brachial
C. cephalic
D. median cubital
E. ulnar
A. basilic
Varicosities in the subcutaneous veins of the medial thigh were observed at physical examination. The vein involved was most likely the:
A. Femoral.
B. Greater saphenous.
C. Lesser saphenous.
D. Popliteal.
E. Pudendal.
B. Greater saphenous.
The general name for an alternate pathway of blood flow in or around an organ, around a joint, or past an obstruction is called:
A. an arteriovenous anastomosis
B. a periarticular network
C. a perivascular plexus
D. a venous plexus
E. collateral circulation
E. collateral circulation
Which vessel courses across the mediastinum in an almost horizontal fashion?
A. Left subclavian artery
B. Left subclavian vein
C. Left brachiocephalic vein
D. Left internal jugular vein
E. Left common carotid artery
C. Left brachiocephalic vein
