What is the subclavian steal syndrome? (SSS)

60%
|

|
Allen´s test
|
|
What is Allen´s test?
|
Grasp patient elevated wrist, compress radial and ulnar arteries while patient makes fist.
Then lower arm while arteries still compressed. Release pressure of one artery. Hand turns red within seconds. Repeat with other artery |
|
Name of test to test the patency of arteries in lower extremities?

1. Lift both legs 45-6+ degrees and hold 30sec
- Note skin color of plants 2. Repeated plantar and dorsal flexion of foot - Note time to provoke claudicatory pain 3. Patient sits up on the bench - Note return of normal color (5s) - Note filling of dorsal veins (10s) - Note redness of whole foot (15s) |

How does acute arterial occlusion manifest symptomatically in patients?
|
Acute sharp pain
Coldness and pallor of extremity Extremity turn cyanotic with ecchymoses Absent pulse No treatment --> Gangrene |
|
What is ecchymoses?
|
Subcutaneous purpura or hematoma larger than 1cm.Wrongly called bruise
|
|
Name 4 syndromes of the upper thoracic aperture?
|
1. Scalenus syndrome
2. Cervical rib syndrome 3. Costoclavicular syndrome 4. Hyperabduction syndrome |
|
What is the scalenus syndrome?
|
Compression between scalenus anticus and medicus muscles
Pressure affect nerves and blood vessels of upper thoracic aperture |
|
By which maneuver (and how does it work) can you document the scalenus syndrome?
|
By Adson´s maneuver.
Arms on knees, head flexed backwards,turned to affected extremity |
|
What is the costoclavicular syndrome?
|
Compression between clavicle and 1st rib
|
|
Costoclavicular syndrome is provoked by?
|
Military attention position, shoulders pressed caudad
|
|
Hyperabduction syndrome is?
|
Compression between clavicle, 1st rib and small pectoral muscle
|
|
Hyperabduction syndrome is provoked by?
|
Hyperabduction of the arm
|
|
Most frequent disease of the veins is?
|
Primary varicosity (varices)
|
|
What are secondary varices?
|
Veins that serve as collaterals in e.g. DVT´s, portal obstruction or IVC obstruction
|
|
Primary varices only occur where?
|
Lower extremities
|
|
Primary varices most frequently affect which vessels?
|
Greater and smaller saphenous vein
|
|
Arterial obstruction is usually due to?
|
Emoblism - less frequent thrombosis
|
|
What does it mean if you feel regurgitating blood in greater saphenous vein when patient cough?
|
Incopentence of ostium / valves
|
|
3 venous systems of LE?
|
1. Deep veins
2. Superficial veins 3. Connecting veins / communicating / perforating |
|
Function of the connecting veins?
|
Connect the deep and superficial system
|
|
Greater saphenous vein is connected with deep venous system via 3 connecting veins. Names?
|
1. Cockett´s connection
2. Boyd´s connection 3. Dodd´s connection |
|
Dodd´s connection is found in which canal?
|
Hunter´s canal - on thigh
|
|
Location of Boyd´s connecting veins?
|
Proximal 3rd of leg (after knee)
|
|
Location of Cockett´s connecting veins?
|
Distal 3rd of leg (before ankle)
|
|
Are there venous valves in legs and feet?
|
Only legs, not feet
|
|
Name of test to test the function of valves in saphenous and communicating veins? (in patients with varicose veins!)
|
Trendelenburg test
|
|
The trendelenburg test: 1st tourniquet, place, function and sign?
|
Place 1st tourniquet on upper thigh in supine patient, to compress the superficial veins.
Patient stand up. Superficial saphenous vein will fill from below in 3-5 seconds. If it fills faster - a problem with valves of deep communicating veins. After 20 s tourniquet released. If rapid filling then - there is a problem with valves of superficial veins. |
