I70.22
Atherosclerosis of native arteries of extremities with rest pain
Clinical Classification Guidelines
Medical Intelligence & Overview
Atherosclerosis of native arteries of the extremities with rest pain (ICD-10 code I70.22) is a condition where buildup of fatty deposits narrows the arteries supplying blood to the legs or arms. This reduced blood flow can cause pain even when at rest, indicating a more severe stage of arterial disease. It's part of a broader category of peripheral artery disease (PAD), which affects blood flow in the limbs. Recognizing and understanding this condition is important for appropriate management and preventing complications such as tissue damage or limb loss.
Causes & Symptoms
Clinical Causes: Chronic buildup of fatty deposits in the arteries (atherosclerosis) High cholesterol levels Chronic smoking High blood pressure (hypertension) Diabetes mellitus Sedentary lifestyle Obesity Family history of vascular disease Aging
Key Symptoms: Resting pain in the legs or arms, especially during the night Numbness or weakness in the limbs Coldness or pallor in the affected extremities Slow or non-healing wounds or ulcers on toes, feet, or fingers Decreased hair growth on the affected limb Weak or absent pulses in the arteries of the limb Cramping or fatigue in limbs during activity
Diagnostic & Treatment
Diagnosis Path: Physical examination to check for pulse strength, color, and temperature of the extremities Ankle-brachial index (ABI) measurement to compare blood pressure in the ankle and arm Doppler ultrasound to evaluate blood flow Angiography, using X-ray imaging with contrast dye, to visualize arteries Magnetic resonance angiography (MRA) or computed tomography angiography (CTA) for detailed images
Treatment Protocols: Lifestyle modifications: quitting smoking, adopting a healthy diet, engaging in regular exercise tailored to the patient's condition, and managing blood pressure and cholesterol Medications: antiplatelet agents (like aspirin), cholesterol-lowering drugs (statins), medications to improve blood flow, and pain management medications Revascularization procedures: angioplasty with or without stenting, and bypass surgery to restore blood flow Wound care: proper management of ulcers or wounds to prevent infection and promote healing In severe cases, limb amputation may be necessary if tissue death (gangrene) occurs
