Lecture 13: Upper Extremity Angiology

Question 1

Axillary Artery Aneurysim

Answer 1

• in patients w/frequent rapid arm movements (Baseball Pitcher)
• compress Brachial Plexus –> leading to loss of sensation and muscle weakness

Question 2

Scapular Anastomosis

Answer 2

• ligate distal to SUBSCAPULAR artery = cut off ALL blood flow to arm
• Dorsal Scapular and Suprascapular flow into Circumflex Scapular Artery via collateral flow

Question 3

What is the most common site of venipuncture and why?

Answer 3

Median Cubital Vein

• very superficial and easy to find
• Bicipital Aponeurosis protects structures below from being damaged

Question 4

What veins form the Axillary Vein?

Answer 4

• Basilic and Brachial Veins come together to form the Axillary Vein
• Cephalic Vein dumps into Axillary Vein around the shoulder region

Which UE Lymph Node is related to metastatic cancer?

Answer 5

• Axillary Lymph Nodes

Question 7

Subclavian Artery Part 2 (branch)

Answer 7

• Costocervical Trunk of the Axillary Artery

Question 8

Subclavian Artery Part 3 (branch and muscles supplied)

Answer 8

• Dorsal Scapular Artery

- supplies Levator Scapulae, Rhomboid Major/Minor M.

Question 9

Where does the Subclavian Artery become the Axillary Artery?

   • Thoracodorsal Artery (Latissimus Dorsi)
2. Anterior Circumflex Humeral Artery
3. Posterior Circumflex Humeral Artery
