Background Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence.Methods ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligible if they had severe unilateral or bilateral carotid artery stenosis and both doctor and patient agreed that a carotid procedure should be undertaken, but they were substantially uncertain which one to choose. Patients were randomly allocated to CAS or CEA and followed up at 1 month and then annually, for a mean 5 years. Procedural events were those within 30 days of the intervention. Intention-to-treat analyses are provided. Analyses including procedural hazards use tabular methods. Analyses and meta-analyses of non-procedural strokes use Kaplan-Meier and log-rank methods. The trial is registered with the ISRCTN registry, ISRCTN21144362.
Totally percutaneous, nonselective sac embolization during EVAR, with a single access on each femoral artery, is feasible and helpful to physicians who wish to perform intraoperative sac embolization without relevant changes in their usual EVAR procedure.
the recent coronavirus disease 2019 pandemic has significantly increased the burden placed on healthcare systems worldwide. This health emergency has led to changes being implemented in the organization of health institutions and has shifted the focus on pandemic management. This has led to marked changes being made in the treatment of patients without COVID-19, and has resulted in more difficult access to healthcare, with ensuing delays in diagnosis and treatment. Vascular diseases, including peripheral artery disease (PAD), require prompt treatment in the majority of cases in order to save affected limbs. Moreover, COVID-19 may result in acute arterial and venous complications, which need to be promptly recognized and treated. The present study describes three paradigmatic clinical cases of hospitalized patients, which are representative of the different forms of the 'lost syndrome' caused by either the direct effect of COVID-19 or by the effects of COVID-19 on the healthcare system and lifestyle factors. Prophylaxis against arterial and venous thrombotic events is crucial in patients with COVID-19, particularly those with a marked inflammatory state. On the other hand, the CoVID-19 pandemic has diminished the access to healthcare system for patients with other chronic pathologies, with potential severe consequences for vulnerable patient groups, such as those with PAD and cardiovascular diseases. For these patients, the authors' experience over the last few months suggests that more suitable measures need to be adopted to avoid additional severe consequences on public health. In addition, it is necessary to identify pathways that will allow these patients to have rapid access to treatment with marked improvements in outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
