Surgery or Endovascular Therapy for Chronic Limb-Threatening Ischemia

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Interventional Radiology

Background:

• Chronic limb-threatening ischemia (CLTI) signifies severe peripheral artery disease with significant morbidity.
• CLTI is defined by ischemic rest pain or tissue loss persisting over two weeks.
• Timely diagnosis and intervention are crucial to prevent amputation.

Purpose of the Study:

• To outline the diagnostic workup for chronic limb-threatening ischemia.
• To emphasize the importance of a structured approach in evaluating CLTI patients.
• To detail the key components of the initial assessment for CLTI.

Main Methods:

• Detailed patient history focusing on ischemic symptoms.
• Comprehensive physical examination, including pulse assessment and wound evaluation.
• Noninvasive vascular studies such as ankle-brachial indices and toe pressures.
• Saphenous vein mapping for potential bypass surgery.
• Lower extremity arterial imaging (CT, MR, or angiography) when revascularization is considered.

Main Results:

• A systematic workup identifies patients with CLTI.
• Noninvasive studies provide initial assessment of arterial flow.
• Advanced imaging is essential for planning revascularization strategies.
• Accurate diagnosis guides subsequent treatment decisions.

Conclusions:

• A thorough diagnostic pathway is fundamental for managing CLTI.
• The described workup facilitates appropriate treatment planning.
• Effective management of CLTI relies on integrated clinical and imaging assessments.
