Summary
The Outback® re-entry device effectively achieves true lumen access in tibio-peroneal arteries, improving outcomes for patients with critical limb ischemia. This study demonstrates its high success rate in challenging cases.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Interventions
Background:
- Re-entry devices are crucial for subintimal recanalization of chronic arterial occlusions.
- Their application in tibio-peroneal arteries is less documented.
- This study evaluates the Outback® device for tibio-peroneal true lumen access.
Purpose of the Study:
- To retrospectively evaluate the efficacy of the Outback® re-entry device.
- To assess its use for targeted true lumen access in tibio-peroneal arteries.
- To determine its role in cases of failed spontaneous re-entry.
Main Methods:
- Retrospective analysis of 14 patients using the Outback® catheter (9/2017-10/2020).
- Device used for failed spontaneous re-entry in tibio-peroneal arteries.
- Data collected included demographics, occlusion characteristics, procedural success, and SVS runoff scores.
Main Results:
- Successful technical and procedural re-entry in all 14 patients (Rutherford stage 4-6).
- Median re-entry accuracy of 0.25 cm.
- Significant improvement in SVS runoff score (14.5 to 7, p<0.01).
Conclusions:
- The Outback® catheter demonstrates high technical and procedural success for tibio-peroneal re-entry.
- It is a valuable option when other recanalization methods fail.
- Consideration for complex tibio-peroneal interventions is recommended.
