OBJECTIVES
![Page 5: Jr approach to the patient with varicose veins april 2010](https://reader036.vdocument.in/reader036/viewer/2022081413/54960065b4795999728b4667/html5/thumbnails/5.jpg)
Scope of the problem
• About 50 % by age 50 (women);men somewhat less 25 % by age 40
• Incidence increases with age for all types of v.v.(spider veins,truncal varicosities).
• Heredity impacts largely on the incidence;eg:if you are female and BOTH parents have v.v.,then the chance is 90%.
![Page 6: Jr approach to the patient with varicose veins april 2010](https://reader036.vdocument.in/reader036/viewer/2022081413/54960065b4795999728b4667/html5/thumbnails/6.jpg)
ANATOMY• Understand that there are 2 parallel systems:• -A)DEEP SYSTEM:responsible for >90% of
venous circulation.Surrounded by muscle pump.
• -B)SUPERFICIAL SYSTEM:Truncal veins are subfascial;the majority in loose subcutaneous tissue.
• -C)PERFORATING VEINS:connect surface to deep.

Pathophysiology
• No one specific ‘cause’.• Primary and secondary causes• Definite genetic component• Primary changes to the integrity of the vein
wall(poorly organized smooth muscle,reduced amounts of elastin,increased amounts of collagen)-all lead to lack of compliance and diminished coaptation of valves.

Pathophysiology
• All changes to the wall and valvular insufficiency lead to venous hypertension and resultant inflammation.
• Many other secondary causes:obstruction(dvt,abdominal,pelvic),mus-cle pump ineffeciency,environmental(hormones,clothing,trauma).

Spider veins

CLINICAL
.Asymptomatic VS Symptomatic
.Asymptomatic have esthetic concerns which may have an impact on their lives
Definite symptoms associated with V.V.

SYMPTOMS
• Discomfort described as heaviness, throbbing,and aching especially when standing
• Night cramps(restless legs)• Swelling-edema• Pruritus-rash• Even spider veins may be symptomatic.Relief
with compression.

Spectrum
• Surface varicosities:• -A)Telangiectasia:spider veins.Smallest veins 1
mm in caliber.May or may not be associated with deeper varicosities.
• -B)Reticular veins:usually 3 mm or less in caliber.Often found on lateral surface of legs.More common in women.
![Page 15: Jr approach to the patient with varicose veins april 2010](https://reader036.vdocument.in/reader036/viewer/2022081413/54960065b4795999728b4667/html5/thumbnails/15.jpg)
Spectrum
• Truncal varicosities:• -leads to dilated,tortuous and bulging veins• -A)GSV:medial aspect proximal to distal with
different patterns.May also be anterior or posterior if tributaries are involved
• -B)SSV:present in posterior calf• -C)Tributaries:more superficial because they
are not subfascial.Anterior/posterior.

Spectrum
• Other;• -Corona phlebectatica:flare of veins on
medial/lateral ankle.Often represents advanced disease.
• -Lipodermatosclerosis:Fibrosis of the skin and subcutaneous tissue.Advanced disease.
• -Venous ulcer:usually found medial ankle.Painful.Advanced CVD.
