Current approach to peripheral arterial sonography.

Area of Science:

• Vascular Medicine
• Diagnostic Imaging
• Medical Ultrasound

Background:

• Color and pulsed Doppler ultrasound are established noninvasive tools for evaluating lower-extremity arterial occlusive disease.
• Ultrasound imaging, combined with indirect arterial tests, is recommended for screening peripheral arterial disease.
• It provides detailed information on disease location, severity, and frequency, aiding therapeutic decisions.

Purpose of the Study:

• To highlight the prominent role of ultrasound imaging in assessing lower-extremity arterial occlusive disease.
• To emphasize the importance of ultrasound in graft surveillance for identifying flow-reducing lesions.
• To explore the potential of emerging ultrasound technologies in peripheral arterial disease assessment.

Main Methods:

• Utilized color and pulsed Doppler imaging for noninvasive evaluation.
• Integrated indirect arterial tests for comprehensive screening.
• Applied ultrasound for graft surveillance to detect flow-limiting lesions.

Main Results:

• Ultrasound imaging effectively determines disease location, severity, and frequency.
• It guides optimal therapeutic approaches before invasive procedures.
• Ultrasound is mandatory for graft surveillance, preventing bypass failure.

Conclusions:

• Ultrasound imaging is a cornerstone in managing lower-extremity arterial occlusive disease.
• Emerging technologies like contrast agents, 3D imaging, and B-flow imaging show significant potential.
• These advancements are expected to enhance diagnostic capabilities and expand vascular applications of ultrasound.
