[Rational approach to peripheral arterial occlusive diseases]
Insights
Physicians increasingly manage peripheral arterial occlusive disease (PAOD) in older adults, characterized by intermittent claudication. Early risk factor assessment and clinical evaluation are crucial for diagnosing and managing this common vascular condition.
Area of Science:
- Vascular Medicine
- Geriatrics
- Diagnostic Imaging
Context:
- The aging global population presents a growing challenge with an increasing prevalence of peripheral arterial occlusive disease (PAOD).
- Stage II PAOD, marked by intermittent claudication, is the typical presentation prompting patients to seek medical attention.
- Identifying established risk factors such as smoking, diabetes, hypertension, and hyperlipidemia is essential for comprehensive patient assessment.
Purpose:
- To outline the diagnostic approach for peripheral arterial occlusive disease.
- To summarize recommended diagnostic and therapeutic strategies for PAOD management.
- To emphasize the importance of assessing atherosclerosis in other vascular territories.
Summary:
- Clinical evaluation, including physical examination and exercise testing, effectively assesses peripheral perfusion.
- Non-invasive techniques like oscillography, Doppler-sonography, and duplex-scanning are increasingly utilized, often obviating the need for angiography.
- Conventional and digital subtraction-angiography remain valuable tools for specific indications in PAOD diagnosis.
Impact:
- Improved early detection and management of PAOD can enhance patient mobility and quality of life.
- Systematic risk factor modification and timely intervention can mitigate disease progression and reduce cardiovascular events.
- This comprehensive overview aids clinicians in optimizing the diagnostic and therapeutic pathways for patients with PAOD.
Abstract:
A growing proportion of over 65-year-old persons in the population will increasingly confront physicians with peripheral arterial occlusive disease. Intermittent claudication is the characteristic symptom of stage II disease at which most patients consult their physician. Known risk factors like cigarette smoking, diabetes, hypertension and hyperlipidemia have to be assessed. Manifestations of atherosclerosis in other vascular beds such as carotids and coronaries should be sought. Clinical angiologic evaluation with inspection, palpation of pulses, auscultation of vessels at rest and after exercise as well as measurement of the walking distance permits assessment of peripheral perfusion quite well. Oscillography and Doppler-sonography are increasingly used. Duplex-scanning can replace angiography in many cases. Conventional and digital subtraction-angiography have their specific uses. Diagnostic and therapeutic measures recommended for peripheral arterial occlusive disease are summarized.
