Pain, paraesthesiae, perishingly cold, pallor, paralysis, pulseless.
Signs of a dead leg?
Mottling and complete neuro defector
Treatment of acute limb ischaemia?
Heparin if recovering, thrombolysis or embolectomy if not.
What is a complication of reperfusing an acutely ischaemic leg?
Sudden release of toxic metabolites, causes oedema which leads to compartment syndrome.
What is an ulcer?
It is a break in an epithelised surface through all the layers.
Risk factors for venous ulcer?
DVT, veinous insufficiency, over-weight, RHF, trauma.
Sloughy ulcer in medial gaiter region?
Venous.
How do you treat venous ulcers?
Swab and clean it. Compression stockings after ABPI confirming no arterial disease
Punched out, painless ulcer which is surrounded by callous?
Neuropathic
Punched out ulcer which is penetrating, painful and ground on pressure founds (between toes, medial aspect of ankle)
Arterial
How do you treat arterial ulcers?
Dress (but not compression bandage), analgesia and manage cardiovascular risk factors.
What vein runs down mid-line of calf and can become varicose?
Small saphenous
What vein runs in the medial aspect of the upper thigh and can become varicose?
Great saphenous vein.
What are varicose veins?
Long, dilated, tortuous veins of the superficial venous system.
How does blood usually flow from
Superficial to deep system?
Perforator veins, sapheno-femoral junction and sapheno-popliteal junctions.
What symptoms can varicose veins have?
Pain, heaviness, tingling, itching. Generally worse at the end of the day.
How are varicose veins classified?
The CEAP classification C0 no signs C1 reticular veins / telangevtasias C2 VV with no complications C3 VV with oedema C4 VV with haemosiderin deposition or lipodetmatosclerosis or eczema C5 healed venous ulcer C6 active ulceration
Treatment for varicose veins?
Conservative - weight loss, avoid prolonged standing
Surgical - radio frequency abalafion, endovascular laser ablation, injection sclerotherapy (liquid sclerosant> foam sclerosant), open surgery.
