Flashcards in Peripheral Vein Disease Deck (69)
What structures within the vein assist in pushing blood back towards the heart?
Define VV (varicose veins)
Dilated, tortuous superficial veins in lower extremeties
What veins are most commonly affected by VV?
Greater saphenous and its branches
what does distention of the vein lead to in VV?
weakened/incompetent valves and dilation along the vein
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
r/f for VV?
congenital or acquired AV fistula
Primary VV orginate in the ______ system?
VV are more common in ____ than ____
females than males
Secondary VV originate in the _______ system and _______?
deep system and perforating veins
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
Duplex imaging is best
DDX of VV
Chronic venous insufficiency
Leg pain d/t 2nd cause
congenital malformation/atresia of deep vein in adolescent patients
Complications of VV
Superfician Venous thrombosis (rare)
Bleeding (secondary to trauma)
Non-surgical TX for VV
avoid prolonged standing
compression stockings (med-heavy) when standing
Leg elevation when possible
Surgical Tx for VV
Radio frequency ablation
Greater saphenous vein stripping
When to refer to a vascular surgeon
Bleeding from VV
define superficial venous thrombosis
Clot that develops in superficial vein
Signs and symptoms of svt?
indurated warm red tender cord extending along superficial vein
T/f SVT can develop into PE?
R/f of SVT?
DDx for SVT?
Supportive TX for SVT
elevation, warm compress, NSAID
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)
Definition of CVI
condition that occurs when wall and/or valves aren't working effectively. Blood can't return to heart
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
CVI is mc in _____ than _____
females than males
Causes of CVI
Secondary to DVT
Hx of leg trauma
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.
subcutaneous veins and tissues
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
