GeneralGreater than 60% associated with diabetes mellitus and renal insufficiency |
Clinical PresentationClaudication: exertional
cramping pain due to
ischemia of muscle bed | Critical Limb Ischemia:
insufficient blood flow
to meet metabolic demand | Iliac vessels Thigh | 1. Rest pain | Femoral Calf | 2. Ulceration | | | 3. Gangrene |
| | Diagnosis and AssessmentA. FUNCTIONAL STATUS
Ambulation - walk up 1 flight of stairs
B. LIMB FACTORS
NM disease, edema, infection
C. ARTERIAL PERFUSION - assess for multilevel disease
| Pulse exam: femoral (R/O suprainguinal inflow disease), popliteal (R/O flow-limiting prox stenosis), PT/DP not commonly palpable
Physiologic testing* - confirm dx of PAD, localize level of obstructive lesions and assess adequacy of tissue perfusion and wound healing potential |
Physiologic TestingDoppler exam
Triphasic - normal transduction of systolic and diastolic pulse
Biphasic - mild/moderate disease
Pressure indices
Ankle-Brachial Index (ABI)
>1.3-1.5 medial calcification resistant to compression
>1.0 Normal
>0.9-1.0 Asymptomatic or minimal disease
0.5-0.9 Claudication
<0.5* Ischemic rest pain/CLI (~ ankle pressure <50)
*ABI >0.5 = single level, <0.5 multilevel disease |
