Q

COLLATERAL CIRCULATION

Around the elbow

A

Superior ulnar collateral artery
- anastomoses with posterior ulnar recurrent artery

Inferior ulnar collateral artery
- anastomoses with anterior ulnar recurrent artery

Middle collateral artery
- anastomoses with interosseous recurrent artery

Radial collateral artery
- anastomoses with radial recurrent artery

16
Q

COLLATERAL CIRCULATION

In the hand

A

Superficial palmar arch

Deep palmar arch

17
Q

Most commonly used for access during long-term hemodialysis

A

Radial & Cephalic vein

18
Q

Placement of ligatures

A

Subclavian or Axillary artery between the thyrocervical trunk & Subscapular artery

Brachial artery distal to the inferior ulnar collateral artery

19
Q

Percutaneous arterial catheterization

A

Uses brachial artery if femoral artery approach is unavailable

Left brachial artery
- preferred because it allows access to the descending aorta without crossing the R Brachiocephalic trunk & L common carotid artery, thereby reducing risk of stroke

20
Q

Brachial plexus

A

Ventral primary rami (C5-T1)
- between anterior & middle scalene muscles

Upper middle & lower trunks
- posterior triangle of the neck

3 anterior & 3 posterior divisions
- deep to the clavicle & are named according to their relation to the axillary artery

Lateral, medial & posterior cords
- axilla, deep to the Pectoralis minor muscle

21
Q

5 terminal branches of BRACHIAL PLEXUS

A

MUSCULOCUTANEOUS nerve (C5,6,7)

AXILLARY nerve (C5,6)

RADIAL nerve (C5,6,7,8,T1)

MEDIAN nerve (C5,6,7,8,T1)

ULNAR nerve (C8,T1)

22
Q

Arise from the brachial plexus proximal to the terminal nerves

Innervate the proximal limb muscles (shoulder girdle muscles)

A

Collateral nerves

23
Q

COLLATERAL NERVE:

Dorsal scapular nerve

A

Structures innervated: RHOMBOIDS

24
Q

COLLATERAL NERVE:

25
Q

COLLATERAL NERVE

Suprascapular nerve

A

Structures innervated: SUPRASPINATUS & INFRASPINATUS

26
Q

27
Q

COLLATERAL NERVE

Medial pectoral nerve

A

Structures innervated: PECTORALIS MAJOR & MINOR

28
Q

A

Structures innervated: SUBSCAPULARIS

29
Q

A

Structure innervated: LATISSIMUS DORSI

30
Q

A

Structures innervated: SUBSCAPULARIS & TERES MAJOR

31
Q

COLLATERAL NERVE

Medial brachial cutaneous nerve

A

Structures innervated: SKIN OF MEDIAL ARM

32
Q

COLLATERAL NERVE

Medial antebrachial cutaneous nerve

A

Structures innervated: SKIN OF MEDIAL FOREARM

33
Q

Violent stretch between the head & shoulder (adduction traction of the arm & hyperextension of the neck)

Nerves damaged:

  • Musculocutaneous
  • Suprascapular
  • Axillary
  • Phrenic

Clinical sign:

  • pronated & medially rotated arm (waiter’s tip hand)
  • ipsilateral paralysis of diaphragm
A

ERB-Duchenne’s (C5 & C6, upper trunk)

34
Q

Sudden upward pull of the arm (abduction injury)

Nerves damaged:

  • Median
  • Ulnar
  • Sympathetic of T1
  • spinal nerve

Clinical sign:

  • loss of function of the wrist & hand
  • Horner syndrome
A

KLUMPKE’s (C8 & T1, lower trunk)
