    Study Notes

    Peripheral Arterial Disease (PAD)

    • Chronic condition marked by partial or total arterial occlusion, leading to lower extremity tissue damage due to insufficient oxygen and nutrients.
    • Most common cause of PAD is atherosclerosis, characterized by arterial plaque buildup.

    Risk Factors

    • Tobacco use and atherosclerosis increase risk.
    • Diabetes and hypertension (HTN) are significant contributors.
    • High cholesterol and age over 60 are also key factors.

    Assessment & Symptoms

    • Intermittent Claudication: Primary indicator; results in muscle pain due to inadequate blood flow.
    • Rest Pain: Numbness or burning in the lower extremities, often occurring at night relieved by hanging the legs down.
    • Lower Extremity Symptoms: Discomfort in back/buttocks, dry/scaly skin, loss of hair, cold and discolored skin, thickened toenails, and reduced peripheral pulses.
    • Elevational Pallor: Skin turns pale when legs are raised, exhibiting reddish color when dependent.

    Complications

    • Prolonged ischemia can lead to skin and muscle atrophy, delayed healing, wound infections, tissue necrosis, and non-healing arterial ulcers or gangrene.
    • Collateral circulation can mitigate gangrene risk, often seen in the elderly.
    • Severe cases may necessitate amputation if blood flow is not restored.

    Arterial Ulcers

    • Typically found on toes or pressure points, appearing pale or cyanotic with irregular margins.
    • Often painful, especially at night; surrounding skin may be shiny and tight.

    Diagnostic Studies

    • Doppler Ultrasound: Maps blood flow; detects significant pressure drops indicating PAD.
    • Ankle-Brachial Index (ABI): Compares ankle and arm blood pressures; a lower ABI suggests PAD.
    • Angiography/Magnetic Resonance Angiography (MRA): Imaging techniques for vascular occlusive diseases.

    Drug Therapy

    • ACE Inhibitors: Effective for reducing PAD symptoms (e.g., Ramipril).
    • Antiplatelet Agents: Aspirin and Clopidogrel to prevent clotting complications.
    • Intermittent Claudication Treatments: Cilostazol promotes vasodilation; Pentoxifylline improves blood flow and reduces viscosity.
    • Exercise: Walking for 30-45 minutes, three times a week is beneficial for claudication management.

    Blood Pressure Medications

    • Calcium channel blockers and vasodilators are used to alleviate symptoms and improve circulation.
    • For severe cases: prostacyclin infusion and surgical debridement might be necessary.

    Phlebitis

    • Acute inflammation of small veins due to IV use, manifests as pain, warmth, and swelling.
    • Treatment involves removing the IV, elevating the limb, and using NSAIDs for inflammation.

    Venous Thrombosis

    • Formation of clots within veins; may lead to deep vein thrombosis (DVT) or superficial vein issues.
    • Venous thromboembolism (VTE) poses a risk of clots traveling to the lungs (pulmonary embolism).

    Venous Stasis

    • Occurs from dysfunctional valves leading to inactive muscle extremities affecting blood flow.
    • At-risk groups include the obese, pregnant, and those with chronic heart failure or prolonged immobility.

    VTE Characteristics

    • Manifestations: Unilateral edema, pain, and redness in the lower extremities along with dilated veins.
    • Diagnostic Tests: Blood tests (e.g., D-Dimer), ultrasound for venous compression, and CT or MR venography for detailed imaging.

    Prevention & Treatment

    • Early mobilization and compression stockings aid in preventing VTE.
    • Anticoagulation therapy is critical for management, using drugs like Warfarin, Heparin, and Direct Thrombin Inhibitors.

    Varicose Veins

    • Caused by dilated superficial veins from increased venous pressure; risk factors include obesity and prolonged standing.
    • Symptoms include heaviness and pain, especially after long standing periods, relieved by movement and leg elevation.

    Chronic Venous Insufficiency (CVI)

    • Abnormalities leading to edema, skin changes, and ulcers due to underlying venous issues.
    • Nursing management includes compression therapy, elevation plans, appropriate nutrition, and monitoring for infections.

    General Management

    • Educate about proper leg care, nutritional needs, and activity to prevent complications.
    • Regular assessments and adjustments to treatment plans based on individual conditions are necessary for effective management.
