PERIPHERAL VASCULAR DISEASE Valerie Robinson D.O. Peripheral Vascular Disease AKA Peripheral Artery Disease • AKA Arteriosclerosis Obliterans • Caused by atherosclerosis • Arterial walls lose compliance • Is usually progressive • May occlude medium and large arteries • Vascular disease may manifest acutely when thrombi, emboli, or acute trauma compromises perfusion. • Risk factors • Dyslipidemia • Diabetes • CAD • HTN • Renal failure • Smoking • Hx of CVA or MI Symptoms • Most commonly found in the lower extremities • Claudication – worse when walking fast, uphill, or for a long distance • Aortoiliac disease manifests as pain in the thigh and buttock, whereas femoral-popliteal disease manifests as pain in the calf • • • • • • • • Slow healing Poor circulation (pale, cool feet) Raynaud’s phenomenon Ulcers and/or Gangrene Neuropathy Night-time leg cramps Pain gets better when leg is hanging Leriche syndrome is a clinical syndrome described by intermittent claudication, impotence, and significantly decreased or absent femoral pulses. Diagnosis: Physical Exam • Peripheral signs of peripheral vascular disease are the classic "5 P's": • Pulselessness • Paralysis • Paraesthesia • Pain • Pallor • Ankle-brachial index • Bruits • Loss of hair on legs and feet, skin becomes pale and shiny • Atrophied muscles, especially calf • Ulcers • Cyanosis/paleness Diagnosis: Tests • Ankle-Brachial Index (ABI) • BPankle/BPbiceps • If <0.9, mild PAD. • Between 0.5 and 0.9 is moderate dz with claudication • If <0.5, severe PAD often has gangrene or ulcers • Doppler • Angiography, MRA, or CTA • Before and after stent Treatment • Increase exercise, but allow time for rest • Control risk factors such as smoking, HTN, lipids, DM • Anti-platelet drugs: aspirin, Plavix (clopidogrel) • Phosphodiesterase inhibitors: Trental (pentoxifylline), • • • • Pletal (cilostazol) Statins Amputation, ABI<0.3 Angioplasty with stents Bypass References • “Peripheral artery disease – legs.” A.D.A.M.
