Transvalvular pulmonic stent angioplasty: procedural outcomes and complications in 15 dogs with pulmonic stenosis
2021, Journal of Veterinary CardiologyCitation Excerpt :We do not know the true rate of thrombosis or granulation tissue ingrowth or at what stage this type of stent may endothelialize in dogs and, therefore, when it is safe to discontinue antiplatelet drugs. One study suggests that a bare metal stent in a peripheral canine artery was completely endothelialized by six months [28]. Ongoing follow-up of these and future cases is planned to better provide information to veterinary cardiologists wishing to perform TPSA using this technique in the future.
Endovascular management of internal carotid artery pseudoaneurysms: Retrospective observational study
2021, Interdisciplinary Neurosurgery: Advanced Techniques and Case ManagementCitation Excerpt :Use of stent-grafts leads to immediate occlusion of the PSA, provided there is no endoleak. Slower endothelialization and thick neointima formation is noted in covered stents compared to bare metal stents (BMS) [24]. Saatci et al, Yi et al and Hoppe et al reported their experience of covered stents in PSA and carotid blow out syndromes with good results [11,25,26].
Surgical and Endovascular Treatments of Extracranial Carotid Artery Aneurysms—Report of Six Cases
2017, Journal of Stroke and Cerebrovascular DiseasesCitation Excerpt :Subacute thrombosis and intimal hyperplasia may be the primary mechanisms in relation to covered stents. Dolmatch et al reported a slower endothelialization and a thicker neointima using a covered stent compared to a bare metal stent in an animal experiment.23 An optimal protocol of antithrombotic therapy, including the duration and type of antiplatelet agent, has not been established on the use of a covered stent for ECAAs.15
Short-Term and Long-Term Outcomes after Polytetrafluoroethylene-Covered Stent Implantation for the Treatment of Coronary Perforation
2015, American Journal of CardiologyCitation Excerpt :The other concern after PCS implantation is the incidence of ST. Other studies have reported a high rate of ST, ranging from 5.5% to 33% from 3 to 6 months.17–20,27 The reason is unknown but may be related to delayed endothelialization of PCS and early discontinuation (<3 months) of DAPT.28,29 In our study, there were no patients who stopped DAPT before the mandated 12 months, with no occurrence of definite early ST. However, late definite ST was seen in 2 patients.
