1

What structures within the vein assist in pushing blood back towards the heart?

Valves

2

Define VV (varicose veins)

Dilated, tortuous superficial veins in lower extremeties

3

What veins are most commonly affected by VV?

Greater saphenous and its branches

4

what does distention of the vein lead to in VV?

weakened/incompetent valves and dilation along the vein

5

What does dilation in VV lead to?

Increased pressure and distention of the vein segment below the valve and progressive failure of the next lower level

6

r/f for VV?

genetics
prolonged standing
pregnancy
congenital or acquired AV fistula

7

Primary VV orginate in the ______ system?

superficial

8

VV are more common in ____ than ____

females than males

9

Secondary VV originate in the _______ system and _______?

deep system and perforating veins

10

Signs and symptoms of VV

can be asymptomatic
doesn't correlate to number and size
if present develops after long periods of standing - dull ache/heaviness or fatigue of legs
may be palpablee in obese
Venous stasis dermatitis
brownish pigmentation and thinning of the skin above the ankle

11

W/u

Duplex imaging is best

12

DDX of VV

Chronic venous insufficiency
Leg pain d/t 2nd cause
-arthritis
-radiculopathy
-arterial insufficiency
congenital malformation/atresia of deep vein in adolescent patients

13

Complications of VV

Superfician Venous thrombosis (rare)
Bleeding (secondary to trauma)

14

Non-surgical TX for VV

avoid prolonged standing
compression stockings (med-heavy) when standing
Leg elevation when possible

15

Surgical Tx for VV

Radio frequency ablation
Greater saphenous vein stripping
Phlebectomy
compression sclerotherapy

16

When to refer to a vascular surgeon

Bleeding from VV
Superficial VV
Pain
cosmetic concerns

17

define superficial venous thrombosis

Clot that develops in superficial vein

18

Signs and symptoms of svt?

indurated warm red tender cord extending along superficial vein

19

T/f SVT can develop into PE?

F

20

R/f of SVT?

Pregnancy
varicose veins
thromboangitis obliterates
trama
systemic hypercoagulability

21

DDx for SVT?

cellulits
erythema nodosum
erythema induratum
lymphangitis
DVT

22

Supportive TX for SVT

Supportive:
elevation, warm compress, NSAID

23

When is anticoag used in the event of an SVT?

only when a thrombus has developed in thigh/arm and is exteding toward the saphenofemoral junction or cephalon-axillary junction (could potentially migrate to the deep system)

24

Definition of CVI

condition that occurs when wall and/or valves aren't working effectively. Blood can't return to heart

25

How are CVI and VV different

VV is dilation and malfunctioning
CVI is when the walls and valves aren't working properly

CVI is a complication of VV but not everyone with VV will develop CVI

26

CVI is mc in _____ than _____

females than males

27

Causes of CVI

Secondary to DVT
Hx of leg trauma
VV
Pelvic tumor
Vaslcular malformation

28

with CVI the ______ ______ are either thickened or scarred, or functionaly inadequate. This causes abnormally high hydrostatic forces that are transmitted to the ______ and _____ of the lower leg.

Valve leaflets
subcutaneous veins and tissues

29

What secondary changes can occur from chronic edema?

fibrosis of subcu tissue and skin
pigmentation of skin
ulceration that are slow to heal
Varicosities if d/t post-thrombotic event

30

DVT
VV
Obestiy
Pregnancy
inactivity
smoking
extended periods of sitting/standint
female
age over 50
