Peripheral venous Flashcards
If you see varicose veins, how do you know which vein it is?
short saphenous - posterior lower leg
long saphenous - medial lower leg & thigh
How would you examine saphena varix? How is it different from a femoral hernia?
while pt is standing w/ cough impulse
femoral hernia is more lateral, smaller, usually reducible
saphena varix - bluish-discoloration
How would you describe inverted champagne bottle legs?
lipodermatosclerosis of the ankles, with edema above the ankles
How would you describe a venous ulcer?
Hx - varicose veins; DVTs site: medial gaiter region of lower leg sloped edges lots of exudate shallow not a lot of pain usually associated w/ limb edema assoc features: venous eczema; hemosiderosis; lipodermatosclerosis; atrophie blanche
How would you Rx a venous ulcer?
conservative - graduated compression dressing w/ antibiotics for infection
How do you know where are the sites of valvular incompetence in varicose veins?
doing the Tredelenburg test
- if no filling on standing & rapid filling on release of tourniquet –> isolated sapheno-femoral junction incompetence
- slow filling on standing & rapid filling on release on tourniquet –> mixed sapheno-femoral junction & perforating vein incompetence
How do you manage varicose veins?
conservative
- elastic support hose
- weight loss
- regular exercise
- avoid prolonged standing
injection sclerotherapy
- suitable for small varices below knee due to incompetence of local perforators
- not satisfactory for varices assoc w/ SFJ incompetence (recurrence inevitable)
surgery
US-guided foam sclerotherapy
Radiofrequency/laser obliteration of LSV/SSV
Why is there a scar from medial malleolus to the knee?
Vein harvesting
Why is there a scar from the medial malleolus to groin?
femoral-distal bypass
What are the causes of chronic venous insufficiency?
valvular incompetence of deep veins (90%)
- primary (etio same as varicose veins)
- secondary (damaged by DVT)
obstruction of deep veins by DVT (10%)
What do you call chronic venous insufficiency secondary to DVT?
post-thrombotic syndrome
What are the causes of unilateral LL swelling?
DVT
Cellulitis
filiriasis
What are the causes of bilateral swelling?
systemic conditions - cardiac failure
How much of a calf difference is significant?
> 3 cm
