Peripheral vascular disease: venous and arterial Flashcards

1
Q

peripheral vascular disease

A

Disrupt the flow of blood through the arteries and veins
Most clients with a PVD have arterial disease rather than venous involvement (some have both)
Atherosclerosis is most common cause

Q

peripheral artery disease

A

More common and results in possible limb loss. Would expect to see pale, cool, thin shiny skin on limb due to lack of blood supply with weak or absent pulses

Q

key features of PAD

A

PAD is term that denotes stenotic, occlusive, and aneurysmal diseases of the aorta and its branch arteries
Fatty deposits build up in artery walls decreasing blood flow to vital organs
Patients at significant risk for: stroke, heart attack, kidney failure, and loss of limb

Q

extensive list of signs/sx of PAD

A

Depends on which arteries are affected (most are leg arteries)
Cramping, pain/discomfort, fatigue in legs and buttocks during activity that stops when activity stops (Claudication)
Numbness, tingling, (paresthesia) or coldness in lower legs or feet
Sores or infection on feet/legs that heal slowly (*still have sensation of pain)
High blood pressure that is hard to control with medication
Decrease in kidney function

Q

stages of chronic PAD

A

Stage 1: Asymptomatic, bruit or aneurysm may be present, pedal pulses may be decreased but can still feel them

Stage 2: Claudication, pain and cramping with exercise so decreased activity

Stage 3: Rest Pain, pain at rest, may awaken patient at night. Typically when pt seeks medical help

Stage 4: Necrosis/Gangrene, feet ulcers

Q

diagnosis for PAD

A
Medical history and physical exam
ABI or ankle brachial index 
Stress (exercise) testing
Duplex ultrasound, graphs of arterial flow
MRA magnetic resonance angiogram
CT angiogram
Regular (catheter-based) angiogram

Q

medical management for PAD

A

Treatment includes antiplatelet agents Pletal (cilostazol) and Trentol (pentoxifylline)

Other antiplatelets include: ASA & Plavix

Anticholesterol medication taken at night bc stomach is empty and cholesterol is made at night

Q

PVD

A

Defects or damage in the peripheral veins

Peripheral venous disorders include:
Thrombophlebitis
varicose veins
venous insufficiency
Effects deep veins, not necessarily superficial

Q

thrombophlebitis

A

Occurs when a blood clot blocks one or more of your veins, typically in your legs and causing inflammation.

Thrombophlebitis can be caused by trauma, surgery or prolonged inactivity. Superficial thrombophlebitis may occur in people with varicose veins.

Warmth, pain, swelling

Heat, elevate, NSAIDs

Q

Varicose veins

A

Weakened valves and veins in legs. Blood pools and veins become weak, large, and twisted.

Run in families

Also obesity and standing long periods increase pressure

Wear compression stockings

Sclerotherapy or Laser Ligation and stripping

14
Q

Venous insufficiency

A

Vein walls are weakened and valves are damaged. This causes the veins tostay filled with blood, especially when you are standing.

Risk with age, obesity, pregnancy, hx DVT, sit or stand for long periods of time

Dull, aching, cramping feeling in legs

Long-term condition

Reddish skin in lower extremities with swelling

Vericose veins superficial and this is deeper

Elevate LE and wear compression stockings, do not sit for long periods of time, keep moving, get proper care for any wounds

16
Q

signs/ sx (50% have 0 or mild sx)

A

Mild inflammation
Fever
Swelling, redness and tenderness to touch, especially in the calf or thigh
Warmth in the affected area
Pain and discomfort with Homan’s sign *no longer reliable

17
Q

DVT

A

clot in deep vein, 98% in LE (those in UE likely due to central line), may lead to PE

18
Q

signs/ sx of PE

A

SOB, unexplained inc in HR, CP

19
Q

preventative measures for DVT

A

SCD, TED hose, lovenox injectoins, anticoag

20
Q

cause of DVT

A

Virchow’s triad: Stasis of blood, Trauma to vessel, Hypercoagulability

21
Q

pathophys of DVT

A

Platelet adherence to endothelium and become clumpy and thick
Platelet Aggregation

22
Q

predisposing factors to DVT

A

immobility (recent travel/ bedrest), disease process (DM, PVD), pressure on area, clotting dysfunction, recent surgery

23
Q

manifestation of DVT

A
None obvious
Related to size and location of thrombus
Unilateral edema
Vital signs (slight inc in temp)
Warmth and pain in calf 

Severe pain is not a sign of DVT!

24
Q

most reliable test for DVT

A

US

25
Q

nursing assessment of pt with DVT (history)

A

history of clot, description of pain, duration of pain, injury or immobility to limb, dehydration

26
Q

nursing eval for pt with DVT

A

Degree of edema
Skin color, compare both sides, temp, assess areas of pain
Peripheral pulses
Assess for Pulmonary Emboli (SOB, CP, inc HR)

27
Q

DVT management

A
Prevention
Immobilization
Anticoagulant therapy
Thrombolytic therapy (TPA)
Compression stockings
Peripheral Intervention Cath lab
Surgical management
28
Q

PVD treatment

A

29
Q

33
Q

How many adults in the US have one or more types of cardiovascular disease?

A

81 million

34
Q

In preparation for home care the nurse initiates a teaching plan about home care after DVT. The effectiveness of the plan can be determined when the patient tells the nurse she will:

A

Not sit or cross legs for prolonged periods
