Catch Up with the Latest Trend in Vascular Intervention-Chronic Limb-threatening Ischemia Up to Date

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Endovascular Interventions

Background:

• Endovascular treatment is widely used for lower extremity artery disease, with proven durability for intermittent claudication.
• Clinical outcomes for endovascular treatment in chronic limb-threatening ischemia (CLTI) are less understood.
• CLTI cases often present complex lesions (small vessels, calcification, CTOs, poor runoff) leading to poorer results.

Purpose of the Study:

• To review existing guidelines and reports on endovascular treatment for lower extremity artery disease.
• To highlight the challenges and current understanding of endovascular treatment in CLTI.
• To provide an overview of the current landscape of endovascular interventions for CLTI.

Main Methods:

• Literature review of previous guidelines and clinical reports.
• Analysis of studies focusing on endovascular treatment for lower extremity artery disease.
• Synthesis of data concerning outcomes in patients with intermittent claudication versus CLTI.

Main Results:

• Endovascular treatment is increasingly recommended for intermittent claudication.
• Data on the efficacy and durability of endovascular treatment for CLTI remains limited.
• Complex lesion characteristics in CLTI contribute to treatment challenges and suboptimal outcomes.

Conclusions:

• While endovascular treatment is effective for intermittent claudication, its application in CLTI necessitates further research.
• Addressing complex lesions in CLTI remains a significant challenge for endovascular therapies.
• The review underscores the need for continued investigation into optimizing endovascular strategies for CLTI.
