31- Venous Disease Flashcards
presence of a clot
thrombus
inflammation within a vein
phlebitis
inflammation of a vein with or without presence of a clot
thrombophlebitis
most common vein for superificial thrombophlebitis
great saphenous v. more commonly than lesser saphenous v.
tenderness, induration, pain and eyrthema along course of a superficial vein. Feel a palpable cord –>
superficial thrombophlebitis
treatment superficial thromboplebitis
NSAIDs, warm compress, elevation
anticoagulation if high risk
pathophysiology of varicose veins
- inadequate muscle pump
- incompetent valves leading to reflux
- venous obstruction
—> all these lead to venous HTN–> skin changes
diagnosis of varicose veins
venous duplex ultrasound reversed flow of greater than 0.5 seconds in duration
what changes are associated with chronic venous insufficiency?
capillary microcirculatory disorders
fibrin deposition
inflammation
–> impair oxygenation of skin and tissue –> edema, hyperpigmentation, fibrosis and ulcer formation
treatment for chronic venous insufficiency
- leg elevation
- exercise
- compression therapy
- skin care
ulcer care =
- debridement
- topical agents
- growth factors
- dressings
- skin grafting
DVT aka
venous thromboembolism
thrombus remains in the deep calf veins
distal DVT
thrombus involves popliteal, femoral or iliac veins
proximal DVT
*** higher risk PE than distal
DVT risk factors
- bed rest/immobilization
- recent surgery
- obesity
- prior thromboembolism
- LE trauma
- malignancy
- oral contraceptives/ hormone replacement therapy
- pregnancy
- stroke
