Peripheral Venous & Arterial Disease Flashcards
Where are superficial veins located
Subcutaneous tissue
Where are deep veins located
Between muscles in limb
In healthy veins blood travels from 1. to 2.
- Superficial
- Deep
What is the course of the superficial veins
Short and long saphenous veins
Deep veins drain into…
Popliteal vein
Femoral vein
Which muscles contribute to the calf muscle pump
Soleus
Gastrocnemius
Function of calf muscle pump
Pushing blood against gravity back towards the heart
Describe how the calf muscle pump works
- Valves open
- Blood pushed through deep vein
- Valves close to prevent retrograde movement
- Perforating valves (between sup. and deep) open again allowing filling from superficial veins
Peripheral venous disease
Varicose veins
-walls of vein weaken
-twisted veins
Varicose veins
Valves ineffective and blood movement is slow/reversed
-saphenous veins are common site of pathology
Symptoms of PVD (peripheral venous disease)
Heaviness
Aching
Muscle cramps
Throbbing
Sign of peripheral venous disease
-leg cramps
-ankle swelling
-varicose eczema
-haemorrhage
Risk factors of peripheral venous disease
Age
Family history
Female sex
No. of births
Occupation-standing a lot
What can peripheral venous disease lead to
Superficial vein thrombophlebitis
-painful erythematous (redness of skin)
-varicose veins
-increased risk of DVT
Examples of chronic venous insufficiency
Complications of varicose veins
-haemorrhage (budge from skin, more susceptible to damage)
-thrombophlebitis (inflammation causes swelling and pain)
-venous hypertension
What is Thrombophlebitis
Inflammation of a vain abused by the formation of a small clot
Complications of venous hypertension
Oedema
Varicose eczema
Lipodermatosclerosis
Venous ulceration
DVT
Main leg pulses
Femoral: mid inguinal point
Popliteal: deep in the popliteal fossa
Dorsalis pedis: lateral to the extensor hallucinations longs tendon
Posterior tibial: behind the medial malleolus
Symptoms of Artery Stenosis
Intermittent claudication
Critical ischaemia (rest pain)
What may develop if artery stenosis is left untreated
Ulceration
Gangrene
Different types of stenosis
Aortoiliac stenosis
Common iliac artery stenosis
Common femoral artery stenosis
Superficial femoral artery stenosis
Sign & Symptoms of occlusion of an artery
