Risultati per: Utilizzo degli stent-retriever nell’ictus ischemico acuto

Circulation, Volume 148, Issue Suppl_1, Page A17285-A17285, November 6, 2023. Background:In-stent yellow plaque (YP) evaluated by coronary angioscopy (CAS) 1 year after stent implantation is associated with the future adverse cardiac event. However, the impact of baseline YP on vascular response has not been fully investigated.Methods:This was a sub-analysis of the Collaboraiton-1 study (multicenter, retrospective, observational study). A total of 88 lesions from 80 patients with chronic coronary syndrome who underwent percutaneous coronary intervention with polymer-free biolimus A9-coated stent or durable-polymer everolimus-eluting stent implantation were analyzed. Optical coherence tomography (OCT) and CAS were serially performed immediately and 11 months after stent implantation. YP was defined as the stented segment with yellow or intensive yellow color assessed by CAS. Neoatherosclerosis was defined as a lipid or calcified neointima assessed by OCT. Neointimal coverage (NIC) over the stent was classified into 4 grades by CAS: grade 0, stent struts fully visible; grade 1, stent struts bulging into the lumen, although covered; grade 2, stent struts embedded in the neointima, but translucently visible; and grade 3, stent struts fully embedded and invisible. OCT and CAS findings at 11 months were compared between the lesions with baseline YP (YP group) and those without YP (Non-YP group).Results:Baseline YP was detected in 37 lesions (42%). OCT findings at 11 months showed that the incidence of neoatherosclerosis was significantly higher in YP than Non-YP groups (11% versus 0%, P=0.028) and mean neointimal thickness tended to be lower (104±43 μm versus 120±48 μm, P=0.098). CAS finding at 11 months demonstrated that dominant and minimum NIC grades were significantly lower (Figure) and maximum yellow color grade was significantly higher in YP than Non-YP groups.Conclusions:Baseline YP affected the incidence of neoatherosclerosis as well as poor neointimal coverage at 11 months after stent implantation.

Stroke, Ahead of Print. Background:The carotid stent design may influence the risk of embolization during carotid artery stenting. The aim of the study was to assess this risk by comparing the quantity of embolized material captured by filters during carotid artery stenting, using different stent designs.Methods:We conducted a single-center retrospective study of patients undergoing carotid artery stenting for asymptomatic carotid stenosis >70% (2010–2022) in a tertiary academic hospital (Padua University Hospital, Italy). Carotid stents were classified according to their design as open-cell (OCS), closed-cell (CCS), or micromesh stents (MMS). A distal filter protection was used in all patients, and the amount of captured embolized particles was semiautomatically analyzed using a dedicated software (Image-Pro Plus, Media Cybernetics). Primary end point was embolic filter debris (EFD) load, defined as the ratio of the filter area covered by particulate material to the total filter area. Secondary end points were 30 days major stroke and death.Results:Four-hundred-eighty-one carotid artery stentings were included; 171 (35%) using an OCS, 68 (14%) a CCS, and 242 (50%) a MMS. Thirty-days mortality was 0.2% (n=1) and major stroke rate was 0.2% (P=0.987). Filters of patients receiving MMS were more likely to be free from embolized material (OCS, 30%; CCS, 13%; MMS, 41%;P

Endosonography-guided choledochoduodenostomy with a lumen-apposing metal stent (EUS-CDS) is a promising modality for the management of malignant distal biliary obstruction (MDBO) with potential for better stent patency. We compared its outcomes with endoscopic retrograde cholangiopancreatography with metal stenting (ERCP-M).
