Venous ulcers Flashcards
Define:
Large, shallow and sometimes painful ulcers usually found above the medial malleoli
Aetiology:
Caused by incompetent valves which lead to the stasis of blood and an increase in pressure leading to ulceration.
Risk factors:
immobility
obesity
recurrent DVT
previous leg injury and surgery
varicose veins
age
Epidemiology:
very common
incidence increases with increased age
Symptoms:
Large + shallow usually painless ulcers above the medial malleoli
- have an IRREGULAR MARGIN
History of:
- DVT
- Varicose veins
- phlebitis
- trauma
- fracture
- surgery
- family history
may have other symptoms:
- swelling
- aching
- itching
Signs:
as above
stasis eczema
lipodermatosclerosis (can look like reverse champagne bottle if severe)
Haemosidern deposition (dark colour)
Investigations:
ABPI - if less than 0.8 do not apply pressure bandage as it can make it a lot worse.
measure surface area to check the progression of the ulcer
swabs for microscopy
biopsy
management:
gradual compression to increase venous stasis - make sure you exclude: diabetes, PVD, neuropathy etc
debridement + cleaning
antibiotics if infected
topical steroids - help with surrounding dermatitis
complications:
recurrence
infection
prognosis:
good
better if there are fewer comorbidities
