HA | PAD vs PVD Only
Description
This episode covers everything PAD vs PVD and highlighting the differences and similarities.
🔎 Big Picture (Pareto)
- PAD = arterial inflow failure ➜ ischemia.
- PVD (venous) = return failure ➜ pooling/edema.
- Position test: PAD pain ↓ with dangling ⬇️🦵; PVD pain/edema ↓ with elevation ⬆️🦵.
- Skin/ulcers: PAD = pale, cool, shiny, hairless; distal, dry “punched-out” ulcers (toes). PVD = warm, brown (hemosiderin), thick; medial ankle, wet/irregular ulcers.
- Pulses: PAD weak/absent 🚫; PVD usually present ✅.
🩸 PAD (Peripheral Artery Disease)
Patho: Progressive arterial narrowing → ↓ perfusion → claudication → rest pain → CLI. Hallmarks: Intermittent claudication (exertional ischemic pain, resolves ≤10 min with rest), paresthesia, shiny/taut skin, hair loss, elevation pallor & dependent rubor, rest pain worse at night/elevation. CLI red flags: >2 wks rest pain, nonhealing arterial ulcers, gangrene (↑ risk w/ DM, HF, prior stroke).
Dx 🧪:
- ABI = ankle SBP / higher brachial SBP (⚠️ may be falsely high in DM/elderly due to calcification).
- Doppler/duplex, segmental pressures, (MR)angiography.
Procedures: PTA ± stent; surgical bypass (autogenous vein preferred); prostanoids (CLI, not FDA-approved for CLI); conservative CLI care (pain control, infection prevention, protect limb).
Nursing priorities 🩺:
- Post-revasc: Hourly distal pulses, color/temp/cap refill; REPORT new pain, pallor/cyanosis, numbness/tingling, pulse loss ➜ possible acute occlusion.
- Positioning: Avoid knee flexion, early ambulation, no prolonged sitting.
- Education: Smoking cessation, daily foot checks, protective shoes (round toe, soft insole), avoid trauma.
- Symptom relief: Dangle legs for rest pain (gravity aids flow).
♻️ CVI & Venous Leg Ulcers (chronic venous PVD)
Patho: Venous hypertension → fluid/RBC leak → edema, inflammation, brown (hemosiderin) discoloration, thick/leathery skin; eczema; painful dependent legs; high infection risk.
Cornerstones of care 🧵:
- Compression = primary (stockings/bandages/IPC/wraps) ONLY after ruling out PAD (ABI first).
- Elevate legs above heart, daily walking; avoid prolonged sitting/standing & trauma.
- Moist wound care, monitor for infection; nutrition: protein + vitamins A/C + zinc; tight glucose control in DM.
🚨 Rapid Compare (teach-back)
- Pain: PAD ⛔ elevation, ✅ dangling; PVD ✅ elevation.
- Pulses/Temp: PAD ↓/cool; PVD normal/warm.
- Color/Skin: PAD pale→rubor, shiny/hairless; PVD brown, thick, edematous.
- Ulcers: PAD toe/distal, dry & round; PVD medial ankle, wet & irregular.
- First moves: PAD ➜ assess pulses, dangle, no compression; PVD ➜ elevate + compress (if no PAD). ✅
