Duplex sonography of lower extremity arteries

Area of Science:

• Vascular Surgery
• Diagnostic Imaging
• Noninvasive Vascular Testing

Background:

• Indirect noninvasive tests are used for lower extremity arterial disease.
• Duplex scanning provides direct anatomic and physiologic data.

Purpose of the Study:

• To evaluate the role and effectiveness of duplex scanning in managing lower extremity arterial disease.
• To highlight duplex scanning as a primary diagnostic tool.

Main Methods:

• Duplex scanning with color Doppler imaging and spectral waveform analysis.
• Comparison of duplex scanning results with arteriography.
• Application in initial screening, post-procedure follow-up, and trauma evaluation.

Main Results:

• Duplex scanning results are comparable to arteriography.
• Color Doppler enhances identification of vessels and flow disturbances.
• Spectral waveform analysis is essential for disease severity classification.
• Duplex scanning effectively determines disease severity and lesion location.

Conclusions:

• Duplex scanning is a primary diagnostic tool for lower extremity arterial disease, comparable to arteriography.
• It is essential for screening, guiding interventions, post-procedural follow-up, and evaluating vascular trauma.
• Evolving applications continue to expand its role in vascular patient management.
