Varicose Veins Flashcards
Define Varicose Veins?
Veins that become prominently elongated, dilated and tortuous, most commonly the superficial veins of the lower limbs
What are the primary causes of Varicose Veins?
Due to genetic or developmental weakness in the vein wall
Results in increased elasticity, dilation and valvular incompetence
What are the secondary causes of Varicose Veins?
Due to venous outflow obstruction
Due to Valve damage (e.g. after DVT)
Due to high flow (e.g. arteiovenous fistula)
What are some examples of causes that are linked to venous outflow obstruction in Varicose Veins?
Pregnancy Pelvic Malignancy Ovarian Cysts Ascites Lymphadenopathy Retroperitoneal Fibrosis
What are the risk factors for Varicose Veins?
Age Female Family History Caucasian Obesity
What is the epidemiology of Varicose Veins?
Common
Incidence increases with age
10-15% of men
20-25% of women
What are the presenting symptoms of Varicose Veins?
Patients may complain about the cosmetic appearance Aching in the legs Aching is worse towards the end of the day of after standing for long periods of time Swelling Itching Bleeding Infection Ulceration
How do we inspect a patient with Varicose Veins?
When standing
What are the signs of Varicose Veins on palpation?
May feel fascial defects along the veins
Cough impulse may be felt over the saphenofemoral junction
Tap Test
Palpation of a thrill or auscultation of a bruit would suggest an AV fistula
What is the Tap Test in the palpation of Varicose Veins?
Tapping over the saphenofemoral junction will lead to an imoulse felt distally (this wouldn’t happen if the valves were competent)
What is the Trendelenburg Test in the physical examination of Varicose Veins?
Allows localisation of the sites of valvular incompetence
Leg is elevated and the veins are emptied
A hand is placed over the saphenofemoral junction
The leg is put back down and filling of the veins is observed before and ater the hand is released from the saphenofemoral junction
A Doppler US can be used to show saphenofemoral incompetence
When we do a Rectal or Pelvic examination for Varicose Veins?
If secondary causes are suspected
What are signs of Venous Insufficiency?
Varicose Eczema Haemosiderin Staining Atrophie Blanche Lipodermatosclerosis Oedema Ulceration
What investigation would you do for Varicose Veins and why?
Duplex US
Locates sites of incompetence or reflux
Allows exclusion of DVT
What is the conservative management plan for Varicose Veins?
Exercise - improves skeletal muscle pump
Elevation of legs at rest
Support stockings
