Carotid, Vertebral, Subclavian, Brachial, Axillary Artery/Venous Study

Questions and Answers

1.

Which Branch of the External Carotid Artery provides a collateral pathway to the Vertebral Artery?
- A.
  
  Lingual Artery
- B.
  
  Occipital Artery
- C.
  
  Facial Artery
- D.
  
  Superficial Temporal Artery
Correct Answer
B. Occipital Artery
2.

In the case of vertebral artery occlusion, which vessel is likely to be enlarged?
- A.
  
  Ipsilateral external carotid
- B.
  
  Contralateral internal mammary
- C.
  
  Contralateral vertebral
- D.
  
  Ipsilateral Subclavian
Correct Answer
C. Contralateral vertebral

Explanation
In the case of vertebral occlusion, compensatory enlargement of Contralateral vertebral is quite common

3.

A 48 y/o mal presents with retrograde flow in the left vertebral artery. This most likely related to occlusion of the:
- A.
  
  Left Subclavian
- B.
  
  Right Vertebral
- C.
  
  Right Subclavian
- D.
  
  Innomonate
Correct Answer
A. Left Subclavian

Explanation
In the case of proximal left subclavian artery occlusion, the left vertebral artery flow will reverse to provide blood flow to the left are. This is termed subclavian steal. Although it occurs more commonly on the left side, it can present to either side of the body.

4.

What is the most common anomaly of the Circle of Willis?
- A.
  
  Duplication of the posterior communicating arteries
- B.
  
  Hypoplasia of the proximal segment of one of the anterior arteries
- C.
  
  Absence of one of the middle cerebral arteries
- D.
  
  Absence or hypoplasia of one or both of the communicating arteries
Correct Answer
D. Absence or hypoplasia of one or both of the communicating arteries
5.

Which of the following is not a branch of the subclavian artery?
- A.
  
  Vertebral artery
- B.
  
  Thyrocervical trunk
- C.
  
  Internal mammary artery
- D.
  
  Brachial artery
Correct Answer
D. Brachial artery
6.

The most common anatomic variant of the aortic arch is:
- A.
  
  A common origin of the innominate and left common carotid arteries
- B.
  
  Origin of the left vertebral from the arch
- C.
  
  Origin of the right subclavian from the aortic arch
- D.
  
  Origin of the right subclavian from the aortic arch
Correct Answer
A. A common origin of the innominate and left common carotid arteries

Explanation
Occurring in approximately 22% of individuals

The subclavian artery becomes knows as what artery after crossing the Lateral margin of the first rib?
- A.
  
  Brachiocephalic artery
- B.
  
  Axillary artery
- C.
  
  Brachilal artery
- D.
  
  Vertebral Artery
Correct Answer
B. Axillary artery

Explanation
The subclavian artery continues as the axillary artery after is passes the lateral margin of the first rib. The axillary artery in turn becomes the brachial artery

8.

The first branch of the external Carotid artery is usually the:
- A.
  
  Facial Artery
- B.
  
  Superficial Temporal Artery
- C.
  
  Internal Maxillary Artery
- D.
  
  Superior Thyroid Artery
Correct Answer
D. Superior Thyroid Artery
9.

The vertebral Artery enters the Transverse foramina of the cervical spine of what level?
- A.
  
  C1
- B.
  
  C7
- C.
  
  C6
- D.
  
  C2
Correct Answer
C. C6
10.

Differentiation of the cervical internal carotid artery from the external carotid is accomplished by all the following EXCEPT:
- A.
  
  The internal carotid artery is usually located anteromedial to the external carotid artery
- B.
  
  The external carotid gives off multiple branches
- C.
  
  There are normally no branches of the ICA
- D.
  
  A bulbous area is seen at the origin of the ICA
Correct Answer
A. The internal carotid artery is usually located anteromedial to the external carotid artery
11.

Which of the following vessels joins the Brachial Veins to form the Axillary Vein?
- A.
  
  Subclavian Vein
- B.
  
  Innominate Vein
- C.
  
  Cephalic Vein
- D.
  
  Basilic Vein
Correct Answer
D. Basilic Vein

Explanation
The basilic vein is a superficial vein in the upper extremity that joins with the brachial veins to form the axillary vein. It begins on the ulnar side of the forearm & crosses ventrally at the antecubical region. The basilica vein lies medial to the brachial artery in the upper arm.

Which vein in the antecubital fossa connects with the cephalic and basilica veins?
- A.
  
  Axillary vein
- B.
  
  Median cubital vein
- C.
  
  Cephalic Vein
- D.
  
  Basilic Vein
Correct Answer
B. Median cubital vein
13.

All of the following are deep veins of the upper extremity EXCEPT:
- A.
  
  Brachial vein
- B.
  
  Cephalic vein
- C.
  
  Axillary vein
- D.
  
  Radial Vein
Correct Answer
B. Cephalic vein

Explanation
The deep veins of the upper extremity included palmer venous arch, radial veins, ulnar veins and interosseous of the forearm, brachial veins, and axillary vein. The deep veins accompany same named arteries & are usually paired. The cephalic, basilica, and medial cubital veins are superficial veins. They do not accompany an artery and are not paired.

The braciocephalic veins is found:
- A.
  
  Only on the right side of the neck
- B.
  
  Only on the left side of the neck
- C.
  
  On both the right and left sides of the neck
- D.
  
  There is no such vein
Correct Answer
C. On both the right and left sides of the neck

Explanation
The venous anatomy of the neck varies from the arterial anatomy in that brachiocephalic vein occurs bilaterally, whereas the brachiocephalic (innominate) artery is found only on the right side. The brachiocephalic vein is formed by the junction of the subclavian and the internal jugular veins.
