Peripheral arterial disease treatment planning using noninvasive and invasive imaging methods

Area of Science:

• Vascular Surgery
• Medical Imaging
• Cardiovascular Disease

Background:

• Peripheral arterial disease (PAD) presents growing prevalence and mortality, necessitating accurate preoperative assessment and risk stratification.
• Current imaging techniques for PAD often lack the detail required for personalized treatment planning, particularly regarding plaque composition.
• Determining the optimal indication for endovascular versus open surgical procedures in PAD remains a clinical challenge.

Purpose of the Study:

• To review the implications of recent invasive and noninvasive imaging techniques for lower extremity peripheral arterial disease.
• To highlight how advanced imaging can improve the assessment of plaque composition and calcification patterns.
• To discuss future directions in imaging for guiding therapeutic decision-making in PAD.

Main Methods:

• Review of state-of-the-art noninvasive and invasive imaging modalities for lower extremity arterial systems.
• Analysis of imaging capabilities in visualizing complex vascular anatomy, plaque burden, and plaque structures.
• Evaluation of current and emerging techniques for assessing pathologic calcium distribution patterns.

Main Results:

• Advanced imaging modalities provide detailed views of vascular anatomy, plaque burden, and complex plaque structures in the lower extremities.
• These techniques offer insights into pathologic calcification patterns, crucial for interventional procedure effectiveness.
• Current limitations in imaging detail are being overcome by newer, more sophisticated diagnostic methods.

Conclusions:

• State-of-the-art imaging enhances the understanding of plaque composition and calcification in peripheral arterial disease.
• Improved imaging accuracy facilitates better patient selection for endovascular treatment and personalized therapy.
• Future advancements in diagnostic methods will further refine treatment planning and device selection for PAD.
