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.
