Peripheral venous assessment Flashcards
Risk factors for developing venous congestion in the lower legs
Obesity
Familial
Age
Pregnancy
Standing for long periods of time
Increased abdominal pressure
Complications of venous congestion in the lower limbs
Varicose veins
Thrombophlebitis
Varicose eczema
Venous ulcers
Blood supply to the leg
Superficial: Great and short saphenous veins
Deep: Femoral vein
Characteristics of a venous ulcer
Superficial
Itchy
Large
Medial malleolus
High exudate level (slough)
Minimal pain
Characteristics of an arterial ulcer
Deep
Small and punched out
Lateral aspect of the leg
Absent pulses
- What is this
- What is it caused by
- Presenting features
- What is the increased colour of the skin due to
- Varicose eczema
- Increased pressure in the venous drainage system of the leg
- Itchiness, appearance, breakage of the skin, oedema, venous ulcer
- Haemosiderin deposit
Why is this a venous ulcer?
Shallow, large, medial aspect of the leg, slough at the base, haemosiderin deposit, thickened skin, surrounded by eczematous skin
What are you looking for in the well’s score?
- Paralysis, paresis or recent orthopedic casting of lower extremity (1 point)
- Recently bedridden (more than 3 days) or major surgery within past 4 weeks (1 point)
- Localized tenderness in deep vein system (1 point)
- Swelling of entire leg (1 point)
- Calf swelling 3 cm greater than other leg (measured 10 cm below the tibial tuberosity) (1 point)
- Pitting edema greater in the symptomatic leg (1 point)
- Collateral non varicose superficial veins (1 point)
- Active cancer or cancer treated within 6 months (1 point)
- Alternative diagnosis more likely than DVT (Baker’s cyst, cellulitis, muscle damage, superficial venous thrombosis, post phlebitic syndrome, inguinal lymphadenopathy, external venous compression) (2 points)
DVT Risk Score Interpretation:
3-8 Points:High probability of DVT
1-2 Points:Moderate probability
0-2 Points:Low Probability
Risk factors for DVT
Age, being in hospital, bedridden, Oestrogen containing contraceptive therapy, HRT, thrombophilias, pregnancy, varicose veins with phlebitis, significant comorbodities, obesity.
NOT: varicose veins per se, admission to hospital (unless critical care)
