Introduction
• The CFA has historically been designated as a ‘no stent zone’
• Treatment of choice - CFA endarterectomy and other surgical repair
• Concerns about CFA stent placement include – Device fracture
– Kinking
– Device failure (restenosis)
– Exclusion of the PFA
– Re-access for future procedures

Percutaneous Treatment of
the CFA • Not all patients are optimal
candidates for CFA surgery
• Unfavorable clinical features
include
– High medical risk
– Morbid obesity
– Prior surgery with failure
– High calcium burden

Percutaneous Treatment of
the CFA • Ideal strategy needs to be defined
• Basic principles
– Angioplasty +/- plaque modification first
– Stents reserved for failed PTA (ad hoc use)
• Ideal stent features
– Flexibility
– Radial strength
– Resistance to restenosis
– Preservation of side branches
– Ease of delivery

Options for Endovascular
Treatment • Balloon Angioplasty
– POBA
– Scoring balloon angioplasty
– Drug coated balloon angioplasty
– Atherectomy with PTA
• Stents
– Woven nitinol (Supera)
– Self expanding
• PTFE covered vs. laser cut nitinol
– Balloon expandable
• Bare metal vs. PTFE covered

So, what is the good, the bad
and the ugly?
• Balloon Angioplasty
– POBA – high restenosis rates
– Scoring balloon angioplasty – limited
data as stand alone therapy
– Drug coated balloon angioplasty –
limited data
• Role of atherectomy – not well
defined yet

So, what is the good, the bad
and the ugly?
• Stent Placement
– Braided nitinol (Supera) – limited
data, favorable properties
– Self expanding – some data, some
favorable properties
• PTFE covered vs. laser cut nitinol tube
– Balloon expandable – limited data,
limited utility, greatest potential for
fracture
• Bare metal vs. PTFE covered

CONCLUSIONS
LINC 2016 - Global Expert Exchange
• Not all patients with CFA disease are optimal candidates for CFA surgery.
• There are multiple viable options for percutaneous treatment of the CFA, incl. PTA and/or stent placement.
• The stent type must be individualized to the clinical situation.
