What’s the Premise?
- Whether patient is presenting as Acute Non-threatened Limb or Non-Acute Limb:
→”Long CTO’s” can mostly consist of thrombus between the caps.

What do we usually do?- Acute
→Cross lesion and place lysis catheters
→ Drip as routine and bring back for treatment
- Non-Acute:
→Cross the CTO→atherectomy/balloon dilate and possible Stent/DCB
→In this method, we determine our final intervention based on the ENTIRE CTO length

What’s the Proposition??
- If wire cross the occlusion luminally (wire test)…
→Mechanical Aspiration initially with Cat8 (”Cat”)
→ Followed by Laser atherectomy of underlying lesion if present
(“Turbo”)
→Then can perform final Intervention

What’s the Premise?
- This unmasks underlying lesion, shorter than expected
- Laser can ablate/pulverize thrombus- (”Limb Salvage Following Laser-Assisted Angioplasty for Critical Limb Ischemia:Results of the LACI Multicenter Trial”Laird J, Zeller T, Gray BH, Sheinert D, Et al. J Endov Therapy. 13(1), 1-11)

Why Single Session?
- Reduce invasiveness and inpatient hospitalization
- Significant costs & morbidities with inpatient stays
- The risks of TPA, are still significant
- More patients with relative or absolute contraindications to CDT

Adjunctive Techniques
• Sometimes proximal stenosis needs pre-ballooning (prefer 3-4mm balloon)
• Contrast column helps visualize the aspiration
• Can instill TPA for 10min across the lesion
• Some have used EPD conjunctively

Summary- Increasing outpatient treatments for even the most
complex issues such as ALI and Decreasing the length of vessel interventions has multifaceted benefits
- Changing our Tx algorithms to single session management of Acute or Non-Acute Limb Ischemia is
one such opportunity
- “TurboCat” technique can result in Cost savings, patient comfort and reduction in comorbidities.
