Unit 6 PVS Flashcards
Arterial disease involves
occlusive disease and aneurysms
Venous disease involves
Venous Thrombosis VTE and Chronis Venous insufficiency
what is happening in PAD
thickening of the arterial, narrowed lumen, loss of elasticity
who is at risk for PAD
Older, diabetes, CVS disease, smoking, hyperlipidemia, uncontrolled hypertension, family history, obesity, stress, male, sedentary lifestyle
Occlusive disease
Decreased or absent blood flow to the lower extremities, most commonly from femoral and popliteal.
Why is occlusive disease popular in pateints with diabetes
because diabetes affects the lining around the cells in teh blood veessels. Making the blood vessels less felxible.
Diabetes and blood clotting
The blood is hypercoagulable platelets clump together more often which speeds up the process of PAD.
What does insulin resistants have to do with PAD
throws off cellular homeostasis- the balance of chemicals and other substances coming in and out of the cells that line the blood vessels means the cells can’t work as well as they should, which increases the chances of PAD.
Signs and Symptoms of PAD
Intermittent Claudication
Erectile dysfunction
Paresthesia
Peripheral Neuropathy
Wounds that don’t heal
Change in skin colour
Changes in skin
Delayed wound healing
Intermittent Claudication
Narrowing involving the femoral or popliteal arteries causes claudication in the calf/buttock during exercise
-This causes lactic acid accumulation
Findings for PAD in inspection
Shiny taut skin, decreased hair growth, purple/red colour, Elevation is pallor and pain
Skin changes in PAD
Thin
Shiny
Hair loss
Elevation pallor
Dependent Rubour
Ulceration
Delayed healing
Gangrene
Loss of palpable peripheral pulses
Why is there so many skinn changes in PAD
Because the skin is not getting enough oxygenated blood and therefore is not able to do its job properly
Arterial wounds are also known as
Arterial ulcers and ischemic ulcers
