Disorders
of the
Peripheral Vascular System

Risk Factors
Similar to risk factors for heart disorders– Age– Gender– Smoking– Hypertension– Hyperlipidemia– Obesity– Lack of exercise– Emotional stress– Diabetes Mellitus– Family History
![Page 3: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/3.jpg)
Assessment of Vascular Disorders Arterial Assessment
– First symptom is usually pain Occurs due to arterial insufficiency and ischemia Dull ache in calf muscles Leg fatigue and cramping Intermittent claudication
– Pain brought on by exercise
– Later symptoms of pain Pain at rest Burning, tingling, and numbness at night even lying down
– Pulses May be weak, thready, or absent
– Scale for documentation• 0 – absent• +1 – barely palpable, intermittent• +2 – weak , possibly thready, but constantly palpable • +3 – normal strength and quality• +4 – bounding, easily palpable, may be visible
![Page 4: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/4.jpg)
Assessment and Documentation– PATCHES
P for Pulses – Absence of pulses in generally a medical emergency
• Compare with previous findings• Look for other symptoms – may just be hard to feel• Use Doppler device if necessary
A for Appearance– Pale, mottled, cyanotic or discolored (red, black, brown)– Necrosis or bleeding (ulcers)
• Size, depth, and location• Edges jagged or smooth• Painful to touch
– Shiny or dull • Shiny may indicate edema• Dull may indicate inadequate arterial blood supply
– Superficial veins, erythema, or inflammation– Varicosities
• Have patient to stand
![Page 5: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/5.jpg)
T for Temperature– Cool
• Possible arterial problem– Warm
• Possible venous problem– Temperature changes may be caused by other problems as well
C for Capillary refill– Less than 2 seconds
H for Hardness– Supple or hard and inelastic
• Hardness may indicate chronic problems E for Edema
– Pitting edema• Usually acute problem• Assessment: Press on skin for 5 seconds and release
(Page 317 --Figure 8-17 and Table 8-3)– Non-pittting
• May be chronic condition• Assessment: Measure circumference of the extremity

![Page 8: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/8.jpg)
Diagnostic Tests
Noninvasive Procedures– Treadmill Test
Exercise to determine blood flow to extremities
– Plethysmography Assesses blood volume in the veins
– Digital Subtraction Angiography (DSA) IV contrast is administered Blood vessels are visualized by radiography using an image
intensifier video system and monitor
– Doppler Ultrasound Measures blood flow in arteries or veins
![Page 9: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/9.jpg)
Diagnostic Tests
Invasive Procedures– Phlebography or venography
Radiographic visualization of veins IV contrast is administered in a foot vein X-rays are taken to detect filling defects Assesses for condition of deep veins and to diagnose deep vein thrombosis
– 125 I-fibrinogen Uptake Test Assesses for acute calf vein thrombosis Fibrinogen is tagged with iodine 125 and given IV - it can then be
detected in the blood stream by a gamma ray detector
– Angiography IV contrast is administered X-ray to visualize arteries
![Page 10: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/10.jpg)
– D-dimer Serum Test D-dimer forms when fibrin is broken down When a thrombus is present D-dimer levels are
elevated – usually greater than 1591 ng/ml Normal value: 68-494 ng/ml
– Duplex Scanning Combination of ultrasound imaging and Doppler Determines location and extent of thrombus within
veins
![Page 11: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/11.jpg)
Arteriosclerosis & Atherosclerosis Arteriosclerosis
– thickening, loss of elasticity, and calcification of arterial walls, resulting in a decreased blood supply
Atherosclerosis– narrowing of the artery due to yellowish plaques of
cholesterol, lipids, and cellular debris in the inner layers of the walls of large and medium sized arteries
– a type of arteriosclerosis
![Page 12: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/12.jpg)

![Page 13: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/13.jpg)
Hypertension
Etiology/Pathophysiology– A sustained elevated systolic blood pressure greater
than 140 mm Hg and /or a sustained elevated diastolic blood pressure greater than 90 mm Hg.
– Vasoconstriction (increases B/P) caused by stimulation of the sympathetic nervous system
and the release of epinephrine and/or norepinephrine. Decreased blood flow to the kidneys causes the release of renin and the formation of angiotensin which is a vasoconstrictor.
![Page 14: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/14.jpg)
Hypertension– Essential (primary) hypertension
90-95% of all diagnosed cases Theories of causes:
– arteriolar changes, sympathetic nervous system activation, hormonal influence, genetic factors, obesity, sedentary lifestyle, increased sodium intake, excessive alcohol intake.
– Secondary hypertension Attributed to an identifiable medical diagnosis
– renal vascular disease– diseases of the adrenal cortex– coarctation of the aorta– head trauma or cranial tumor– pregnancy-induced hypertension
![Page 15: Nursing of Adults with Medical & Surgical Conditions](https://reader035.fdocuments.in/reader035/viewer/2022062718/56812ba4550346895d8fd849/html5/thumbnails/15.jpg)
