Lecture 13: Upper Extremity Angiology Flashcards
Axillary Artery Aneurysim
- in patients w/frequent rapid arm movements (Baseball Pitcher)
- compress Brachial Plexus –> leading to loss of sensation and muscle weakness
Scapular Anastomosis
- ligate distal to SUBSCAPULAR artery = cut off ALL blood flow to arm
- Dorsal Scapular and Suprascapular flow into Circumflex Scapular Artery via collateral flow
What is the most common site of venipuncture and why?
Median Cubital Vein
- very superficial and easy to find
- Bicipital Aponeurosis protects structures below from being damaged
What veins form the Axillary Vein?
- 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?
- Axillary Lymph Nodes
- common site for breast cancer to metastisize at
Subclavian Artery Part 1 (branches and muscles supplied)
- Thyrocervical Trunk of the Axillary Artery
- 2 branches:
- Transverse Cervical A –> Trapezius M.
2. Suprascapular A –> Supra/Infraspinatous M.’s
- Transverse Cervical A –> Trapezius M.
Subclavian Artery Part 2 (branch)
- Costocervical Trunk of the Axillary Artery
- found BEHIND Anterior Scalene M.
Subclavian Artery Part 3 (branch and muscles supplied)
- Dorsal Scapular Artery
- supplies Levator Scapulae, Rhomboid Major/Minor M.
Where does the Subclavian Artery become the Axillary Artery?
anterior to 1st rib
Axillary Artery Part 1 (branch and areas supplied)
Superior Thoracic Artery
- supplies: Superior Thoracic Wall
Axillary Artery Part 2 (branches and muscles supplied)
- Thyroacromial Branch (C,A,D,P)
- Pectoral Branch supplies Pec. Major/Minor
- Lateral Thoracic Artery
- supplies: Serratus Anterior M.
Axillary Artery Part 3 (branches and muscles supplied)
- Subscapular Artery (2 branches off)
- Circumflex Scapular Artery (scapular anastomoses)
- Thoracodorsal Artery (Latissimus Dorsi)
- Anterior Circumflex Humeral Artery
- Posterior Circumflex Humeral Artery
- supplies Pec. Major/Minor muscles
Where does the Axillary Artery become the Brachial Artery?
Distal to Teres Major M.
What arteries do the Superior Ulnar Collateral and Inferior Ulnar Collateral Arteries become?
SUCA –> Posterior Ulnar Recurrent Artery
- behind medial epicondyle
IUCA –> Anterior Ulnar Recurrent Artery
What arteries do the Radial Collateral Artery and Middle Collateral Artery become?
RCA –> Radial Recurrent Artery
MCA –> Interosseous Recurrent Artery
- behind elbow, connects with Posterior Interosseous Artery
What two branches does the Deep Brachial Artery form?
Radial Collateral Artery and Middle Collateral Artery
What is the order of arteries that supply the palmar side of the digits and come off of the Superficial and Deep Palmar Arches?
Common Palmar Digital Arteries –> Proper Palmar Digital Arteries
What are the palmar arteries that supplies the thumb and 2nd digit?
Thumb –> Princep Pollicis A.
2nd Digit –> Radialis Indicis A.
What two arteries supply the Dorsal Carpal Arch and are located on the posterior side of the forearm?
Anterior Interosseous A. and Posterior Interosseous A.
What is the series of arteries that come off of the Dorsal Carpal Branches to supply the dorsal digits?
Dorsal Metacarpal A. –> Dorsal Digital A.
What are the two arteries that supply the dorsal side of the thumb and lateral dorsal side of the 2nd digit?
Thumb: Dorsalis Pollicis A.
2nd Digit –> 1st Dorsal Metacarpal A.
What is the artery that supplies the medial side of the 5th digit on the palmar side?
Palmar Digital A.
