[Peripheral arteriosclerosis. Early diagnosis]

Area of Science:

• Vascular Medicine
• Diagnostic Imaging

Context:

• Peripheral vascular disease (PVD) diagnosis relies heavily on symptom interpretation.
• Early-stage PVD may present with non-specific or absent pain, complicating clinical assessment.
• Traditional diagnostic methods can be limited in detecting subtle circulatory impairments.

Purpose:

• To evaluate the diagnostic utility of various methods for early peripheral vascular disease detection.
• To highlight the limitations of clinical history in diagnosing early-stage PVD.
• To compare the effectiveness of Doppler ultrasound and other techniques in identifying blood flow disturbances.

Summary:

• Pain is an unreliable early indicator of peripheral vascular disease.
• Doppler ultrasound is a simple and rapid diagnostic tool for PVD.
• Venous occlusion plethysmography, 133Xenon tissue clearance, and pulse wave analysis provide valuable data on early circulatory issues.
• Key pulse wave parameters include peak-flow, catacrote areal index, peak delay, and sum of pulse peak and delay.
• Cut-off value evaluation aids in differentiating normal, early pathological, and advanced pathological conditions.

Impact:

• Improves early detection rates of peripheral vascular disease.
• Facilitates timely intervention, potentially preventing disease progression.
• Enhances diagnostic accuracy, reducing reliance on subjective symptom reporting.
• Suggests future roles for B-scanning and digital subtraction angiography in PVD assessment.
