Q

When is it considered a DVT? What should be done?

Q

SVT is associated with an occult of DVT ___% of the time

A

20%

20
Q

DDX of SVT (2)

A

Lymphangitis

Cellulitis

21
Q

What are the LSV branches below the knee

A
Posterior accessory (medial) 
Anterior accessory
22
Q

The posterior accessory vein of the GSV communicates with the _____ via the _____

A

Posterior accessory vein of GSV communicates with
Posterior tibial veins
Via
medial calf perforators

23
Q

Differentiating factor between superficial veins and deep veins (3)

A
  • Superficial travel without accompanying A (like the deep)
  • Superficial V encapsulated within fascia
  • Function to bring blood to skin (not return blood to heart)
24
Q

Where does the GSV enter the femoral V

A

Through foramen ovale at the SFJ

25
Q

What does the surgeon need to do in the Rx of the varicose vein?

A

Because there are many tributaries joining the GSV at SFJ, the surgeon needs to ligate all these tributaries and + GSV to prevent recurrence of varicose veins

26
Q

How many tributaries join the GSV at the SFJ and what are they draining

A

At least 6

Draining perineum, lower abdo/groin

27
Q

What is the other name for superficial vein thrombosis SVT

A

Superficial throbophlebitis

28
Q

does the clot in superficial venous system pose any threat of PE

A

Yes

29
Q

Where the thrombus should be in the superficial system near the juction within the deep system to pose a threat of PE and treat as DVT

A

Within 2 cm of the deep system

30
Q

what is felt with an enlarged superficial vein with clot

A

Leg discomfort

31
Q

why is the clot unlikely to dislodge from the superficial veins compared with deep

A

Because superficial veins are NOT surrounded by muscles. Instead, superficial are surrounded by fascia

32
Q

Where do must SVT occur

A

Vericose veins

33
Q

What is the % of saphenous vein duplication below the knee

A

30%

34
Q

Medial calf perforators connect what

A

Posterior accessory vein of LSV and posterior tibial vein

35
Q

Where does the short saphenous vein arise from (SSV), where does it course, where does it dump into

A

Dorsal venous arch of lateral aspect passing behind lateral malleolus

Runs posterolateral up calf

Dump into popliteal vossa

36
Q

the giacomini vein is what? How does it course

A

It is the SSV BUT it passes more superiorly in thigh to join profunda femoris vein

NOT the popliteal vein in pop crease

37
Q

Perforator vein role (2)

A

Superficial to deep

Keeps blood from pooling at skin level

38
Q

Standard sites for perforators (2)

A

Junction midthigh to distal thigh

At calf

39
Q

If deep and perforators become incompetent, where does blood go?

A

Superficial system

40
Q

Where does superficial thrombophlebitis occur

A

Basilic and cephalic veins

41
Q

where do basilic/cephalic veins dump into

A

Subclavian vein

42
Q

What is the most common cause of SVT in upper limb

A

IV infusion - chemical injury to vein wall - inflammation - inevitable thrombosis

43
Q

SVT in upper limb is associated with (2)

A

Trosseau’s syndrome

Buerger’s disease

44
Q

Does SVT accompany DVT of upper limb

A

Yes, it is often SVT accompanies DVT in the upper limb

45
Q

What are the findings of SVT in the upper limb (3)

A

Palpable tender cord in neck/axilla
Bluish discolouration fingers
Aching pain forearm exacerbated by exercise
