  1. Membrane meshcoveredstentshave a bright future the iron-guardstudy Laura Capoccia Vascular and Endovascular Surgery Division, Chief Prof. Francesco Speziale, Department of Surgery “Paride Stefanini”, Policlinico Umberto I, “La Sapienza” University of Rome, ITALY on behalf of the IRONGUARD Study Group Collaborators

  2. Risk of embolism RISK OF CAS-RELATED EMBOLISM? Nitinol expansion Stent deployment Filter positioning Predilatation Time Postdilatation

  3. Plaquehealing 28 days? OCT Plaque proplase and distal embolization through the stent struts during the first 30-day

  4. Reductionofperioperativeneurologicembolization Membrane-coveredstent Distalembolicprotectiondevice stenting ballooning Flow-reversalembolicprotectiondevice time

  5. IS A MESH-COVERED STENT ABLE TO CAPTURE EVERY KIND OF EMBOLISM?

  6. EVEN THE “OFF-TABLE” ONE?

  7. New generation stents IDEAL PORE SIZE Double-layers surface to prevent embolization CGUARD™ Closed cell stent Open cell stent TERUMO * Average in lesion at expanded state C-Guard stent is an innovative monorail, self-expanding, open cell, nitinol stent covered by a polyethylene terephthalate (PET) micromesh. GORE

  8. Iron-guardstudy To report on outcomes in a prospective series of patients submitted to protected CAS with C-Guard stent (InspireMD, Boston, MA, USA) between 04-2015 and 06-2016 Primary endpoints Periop. Major Adverse Cerebrovascular Cardiac Event (MACCE) Procedure-related brain embolism (24/72hrs DWMRI) Secondary endpoints technical success, procedural success, 1 month MACCE Post-op and 12-month results analysis Speziale, Capoccia et al. EuroIntervention 2017

  9. Iron-guardstudy Physician-initiated prospective multicenter registry 12 centers performing >50 CAS per year 200 patients enrolled • Inclusion Criteria: • ≥ 50% symptomatic stenosis, or ≥ 70% asymptomatic stenosis; • target lesion located in the distal CCA, ICA, or carotid bifurcation; • target vessel diameter between 4mm and 9mm; • life expectancy > 12 months; • willing and able to comply with follow-up requirements.

  20. conclusions Data from the present physician-initiated, real-life, multi-center study demonstrate 30-day efficacy and safety of CAS using exclusively the novel MicroNet-covered embolic prevention stent CGuard, with a significant reduction of post-procedural adverse neurologic events in a predominantly asymptomatic cohort.

  21. The cas dilemma Is the C-Guard the answer …

  22. The cas dilemma …to the “embolus-hunt”?

  23. Is the c-guard the answer to the “embolus-hunt”? yes Because the embolism rate is extremely low (19.6%) no Because that embolism rate is observed at 24-72 hours postoperatively

  24. plaquehealingperiod 28/30 days When is the best time to perform DWMRI? Do we need more than one DWMRI? Is DWMRI able to detect all we want to know about the after-CAS brain?
