Outback catheter-assisted simultaneous antegrade and retrograde access for subintimal recanalization of peripheral...

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Endovascular Techniques

Background:

• Severe peripheral vascular disease (PVD) with tissue loss or rest pain presents significant challenges, especially for patients with limited surgical options.
• Subintimal recanalization techniques have emerged as a viable treatment strategy for complex PVD.
• Percutaneous intentional extraluminal recanalization (PIER) aims to restore blood flow by accessing the subintimal space.

Observation:

• This report details the use of an Outback catheter for accessing the subintimal channel.
• The Outback catheter was employed in an antegrade fashion to gain entry from the true lumen.
• This approach was utilized within the framework of the subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) technique.

Findings:

• The study demonstrates the successful application of the Outback catheter in an antegrade manner for PIER.
• This represents the first reported use of the Outback catheter in this specific configuration within the SAFARI technique.
• The technique facilitated access to the subintimal space from the true lumen.

Implications:

• This novel application of the Outback catheter may expand treatment possibilities for patients with complex PVD.
• The SAFARI technique, augmented by this antegrade catheter approach, could offer a less invasive option for limb salvage.
• Further research is warranted to evaluate the long-term efficacy and safety of this specific technique.
