Interventional procedure overview of transfemoral carotid artery stent placement for asymptomatic extracranial carotid stenosis
Closed for comments This consultation ended on at Request commenting lead permission
Methods
NICE identified studies and reviews relevant to transfemoral carotid artery stent placement for asymptomatic extracranial carotid stenosis from the medical literature. The following databases were searched between 2011 to 28/02/2023: MEDLINE, PREMEDLINE, EMBASE, Cochrane Library and other databases. Trial registries and the internet were also searched (see the literature search strategy). Relevant published studies identified during consultation or resolution that are published after this date may also be considered for inclusion.
The following inclusion criteria were applied to the abstracts identified by the literature search.
Publication type: clinical studies were included with emphasis on identifying good quality studies. Abstracts were excluded if they did not report clinical outcomes. Reviews, editorials, and laboratory or animal studies, were also excluded and so were conference abstracts, because of the difficulty of appraising study methodology, unless they reported specific adverse events that not available in the published literature. Because of the size of the evidence base, a separate broad search was done to identify randomised controlled trials and systematic reviews.
Patients with asymptomatic carotid stenosis.
Intervention or test: transfemoral carotid artery stent placement.
Outcome: articles were retrieved if the abstract contained information relevant to the safety, efficacy, or both.
If selection criteria could not be determined from the abstracts the full paper was retrieved.
Potentially relevant studies not included in the main evidence summary are listed in the section on other relevant studies.

Two sets of searches were conducted – a precise search for all study designs and a more sensitive version that was limited by study design.
