Technical endovascular highlights for crossing the difficult aortic bifurcation.

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Endovascular Techniques

Background:

• Effective endovascular treatment necessitates precise vascular access to target lesions.
• Infrainguinal lesions require specific access strategies, including ipsilateral antegrade femoral, contralateral retrograde femoral, or transbrachial approaches.
• The contralateral retrograde femoral approach is common but presents challenges, particularly with scarred groins or complex aortic bifurcations.

Purpose of the Study:

• To provide technical guidance for challenges in obtaining contralateral femoral access.
• To address difficulties encountered during peripheral interventions involving a challenging aortic bifurcation.

Main Methods:

• Review of common techniques for contralateral femoral access.
• Discussion of anatomical considerations for difficult aortic bifurcations.
• Presentation of practical tips and strategies for successful access.

Main Results:

• Identification of key challenges in contralateral femoral access for infrainguinal interventions.
• Elaboration of specific technical maneuvers to navigate difficult aortic bifurcations.
• Guidance on optimizing access in scarred groins.

Conclusions:

• Contralateral femoral access is crucial for infrainguinal endovascular procedures.
• Specific technical tips can improve success rates when facing challenging aortic bifurcations.
• Mastering these techniques enhances the efficacy of peripheral interventions.
