Purpose
1. To review the indications and rationale for performing alternative forms of access to perform or guide arterial recanalization. 2. Techniques include radial, brachial, popliteal, and pedal access. 3. To guide the reader through the anatomy, patient selection, interventional methods, benefits, and potential complications of these different access techniques. 4. Case examples will be presented to highlight the techniques.
Materials & Methods
The conventional access point for performing lower extremity and pelvic arterial intervention is the common femoral artery. However, the failure rate in recanalizing chronic total occlusions (CTOs) approximates 20% from this approach for lower extremity intervention. In these cases (and even for primary intervention), alternative arterial access sites can be utilized to facilitate or perform endovascular recanalization.
Results
A. Review of rationale for patient selection for different access sites for pelvic and lower extremity arterial recanalization. B. Graphic and radiographic guide to radial, brachial, popliteal, and pedal access, as well as various recanalization techniques, with case examples. C. Overview of relevant inventory for arterial recanalization via these access sites. D. Visual overview of outcomes and complications.
Conclusions
Ultrasound-guided arterial access via radial, brachial, popliteal, or pedal arteries provide alternatives/adjuncts to traditional access techniques for successfully treating lower extremity chronic total occlusions. Interventionalists treating peripheral arterial disease should be familiar with these techniques.
