Peripheral Vascular Disease (PVD) Flashcards
What does PVD affect?
Both Arteries and Veins
What is Arteriosclerosis?
The thickening, loss of elasticity and calcification of arterial walls
It is the most chronic arterial disorder
PAD is caused by arteriosclerosis
Peripheral Vascular Disease (PVD) include:
Peripheral Arterial Disease (PAD) &
Peripheral Venous Disorders.
PAD affects…?
Peripheral Venous Disease affects…?
Arterials - Vessels carrying blood Away from heart (to the periphery.)
Veins - Vessels carrying blood to the heart
What is Atherosclerosis?
Gradual thickening of the intima & media of the arteries, ultimately narrowing the vessel lumen. Plaques form on the wall.
Progressive arteriosclerosis (stiffening) & progressive atherosclerosis (narrowing) causes what?
Decreased blood supply to the peripheral tissues & increased resistance to blood flow
Where does tissue damage usually occur?
Below the arterial obstruction
What are some Risk Factors for PAD?
HTN Hyperlipidemia DM Cigarette Smoking Obesity Sedentary Lifestyle Familial Predisposition Age
What are some main Chief Complaints from a pt. with PAD?
Burning, Cramping Pain in the Legs During Exercise (KNOWN AS INTERMITTENT CLAUDICATION)
Numbness or Burning Pain When Elevated
How is pain relieved in patients with PAD?
Legs should be placed in a dependent position
What are some normal objective findings in patients with PAD?
- Bruit over femoral & aortic arteries
- Capillary refill >3 seconds
- Decreased or Nonpalpable Pulses
- Hairless, dry, scaly, shiny skin.
- Elevated Pallor or Dependent Rubor (RED)
- Muscle Atrophy
- Ulcers & gangrene toes
What are some diagnostic tests that can be performed for pt. with PAD?
Arteriography - Injection of Contrast X-ray
Stress Test - Used to Evaluate Intermittent Claudication
What are some nursing actions r/t Arteriography?
Monitor for bleeding & hemorrhage
Take vital signs
Palpate pedal pulses to ID possible occlusions
What are some Nursing Interventions to help a pt. with PAD?
- Encourage pt. to exercise - supports collateral circulation.Exercise gradually & slowly. Walk until claudication, stop & rest, then walk more.
- Positioning - Avoid crossing legs, No belts, Elevate Legs But Not Above Heart.
- Promote Vasodilation - Warm environment, socks, avoid cold.
What kind of medications should be administered to a pt. with PAD?
- Antiplatelets - ASA, Plavix:
Reduces blood viscosity, Increases blood flow
Monitor for bleeding - Abd pain, coffee ground emesis, black stools. - Statins - Simvastatin & Atorvastatin:
Relieves S/S of PAD claudication
What is Percutaneous Transluminal Angioplasty?
Using a Balloon & Stent to open & maintain patency of the vessel.
What are some nursing actions to care for a pt. that underwent PTA?
- Monitor for bleed
- Monitor vital signs, Peripheral pulses & Capillary refill
- Anticoagulant therapy
What is Arterial Revascularization Surgery?
Surgery reserved for severe PAD when pain happens during rest.
It’s a bypass graft that retoutes the circulation around the occlusion
What are some nursing actions r/t Arterial Revascularization bypass graft surgery?
- Maintain adequate circulation
- Pedal or dorsal pulse should be marked & strength compared with other leg with
- Assess for warmth, redness, edema of affected limb as a result of increased blood flow.
- Monitor the client for pain. May be severe bc of reestablishment of blood flow.
- Monitor BP. Hypotension may result & increase risk for clotting & HTN increases risk for bleeding.
What should I teach my pt. about bypass graft surgery?
- Do not cross legs
- Do not raise legs above heart level
- Instruct on wound care
- Discourage smoking & cold temperatures
- Foot care
Keep dry, wear good fitting shoes, no bare foot, cut toenails across
What is graft occlusion & what is the nurses priority?
Complication of arterial revascularization occurring within the 1st 24 hrs.
- Promptly notify physician of manifestations:
a. Decreased Pedal Pulses
b. Increased Pain
c. Change In Extremity Color
d. Temperature Change
What is compartment Syndrome?
Considered a medical emergency
Tissue pressure within a confined body space can restrict blood flow which results in ischemia that leads to irreversible tissue damage.
Clinical Manifestations of Compartmental Syndrome
& Nursing Interventions
Tingling Numbness Worsening Pain Edema Unequal Pulses IMMEDIATELY REPORT TO PHYSICIAN Loosen dressing
