Alternative access for peripheral vascular interventions.

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Endovascular Interventions

Background:

• Advanced lower extremity peripheral arterial disease (PAD) and chronic limb-threatening ischemia (CLTI) are increasingly managed with percutaneous endovascular interventions.
• Endovascular techniques provide safe and effective revascularization, particularly for high-risk surgical patients.
• The standard transfemoral approach has limitations, with up to 20% of lesions being difficult to access.

Purpose of the Study:

• To review alternative arterial access sites utilized in endovascular management of CLTI and PAD.
• To discuss the outcomes associated with various alternative access strategies for limb salvage.

Main Methods:

• Review of literature focusing on endovascular interventions for PAD and CLTI.
• Discussion of alternative access sites including transradial, transpopliteal, transpedal, transbrachial, and transaxillary approaches.
• Analysis of technical success, patency rates, and limb salvage outcomes for each approach.

Main Results:

• Alternative access sites are crucial for managing challenging lesions in CLTI and PAD.
• Transradial, transpopliteal, and transpedal approaches offer viable options when transfemoral access is unsuccessful.
• These alternative methods contribute to successful limb salvage in complex peripheral arterial disease cases.

Conclusions:

• Alternative endovascular access sites are essential for comprehensive management of peripheral arterial disease and limb salvage.
• Exploring diverse access routes expands treatment options for patients with chronic limb-threatening ischemia.
• Optimizing access strategies improves outcomes in challenging lower extremity interventions.
