Extracranial Carotid Stenosis
1.1 Guidelines
1.1.1 Guideline oftheEuropean Society forVascular Surgery (ESVS) [1]
1.1.1.1 Unchanged Recommendations
• No. 19: For average surgical risk patients with an asymptomatic 60–99% steno-
sis, carotid endarterectomy should be considered in the presence of one or more imaging or clinical characteristics that may be associated with an increased risk of late stroke, provided 30day stroke/death rates are ≤3% and patient life expec­tancy exceeds 5 years. (Class IIa/Level B).
• No. 20: For average surgical risk patients with an asymptomatic 60–99% steno-
sis in the presence of one or more imaging or clinical characteristics that may be associated with an increased risk of late stroke, carotid stenting may be an alter­native to carotid endarterectomy, provided 30 day stroke/death rates are ≤3% and patient life expectancy exceeds 5 years. (Class IIb/Level B).
• No. 40: For patients reporting carotid territory symptoms within the preceding 6
months and who have a 70–99% carotid stenosis, carotid endarterectomy is recommended provided the 30 day risk of death/stroke rate is <6%. (Class I/Level A).
• No.41: For patients reporting carotid territory symptoms within the preceding 6
months and who have a 50–69% carotid stenosis, carotid endarterectomy should be considered provided the documented 30day risk of death/stroke rate is <6%. (Class IIa/Level A).
• No. 42: For patients aged ≥70years who have experienced a carotid territory
transient ischaemic attack or ischaemic stroke within the preceding 6months in association with a 50–99% carotid stenosis, it is recommended that they should

be treated by carotid endarterectomy, rather than carotid stenting. (Class I/ Level A).
• No. 43: For patients aged <70years who have experienced a carotid territory
transient ischaemic attack or ischaemic stroke within the preceding 6months in association with a 50–99% carotid stenosis, carotid artery stenting may be con­sidered an alternative to endarterectomy, provided the documented 30day risk of death/stroke is <6%. (Class IIb/Level A).
• N0. 44: For symptomatic patients with a 50–99% stenosis in whom a carotid
intervention is considered appropriate, it is recommended that this be performed as soon as possible, preferably within 14 days of symptom onset. (Class I/ Level A).
• No. 45: For patients who are undergoing revascularisation within the rst 14days
after onset of symptoms, it is recommended that they should undergo carotid endarterectomy, rather than carotid stenting. (Class I/Level A).
• No. 46: For patients with 50–99% stenoses who experience a disabling stroke
(modied Rankin score≥3), or whose area of infarction exceeds one third of the ipsilateral middle cerebral artery territory, or who have altered consciousness/ drowsiness, it is recommended to defer carotid interventions to minimise the risks of post-operative parenchymal haemorrhage. (Class I/Level C).
• No. 47: For patients with 50–99% stenoses who present with stroke in evolution
or crescendo transient ischaemic attacks, urgent carotid endarterectomy should be considered, preferably within 24h. (Class IIa/Level C).
1.1.1.2 New Class IRecommendations Are Among Others
• No. 23: For symptomatic carotid stenosis patients who are not being considered
for carotid endarterectomy or stenting following a transient ischaemic attack or minor ischaemic stroke, short term aspirin plus clopidogrel for 21days followed by clopidogrel monotherapy, or long term aspirin plus dipyridamole modied release is recommended.
• No. 24: For recently symptomatic carotid stenosis patients who are not being
considered for carotid endarterectomy or stenting who are intolerant of, or aller­gic to, aspirin and clopidogrel, dipyridamole monotherapy or ticagrelor mono­therapy is recommended.
• No. 25: For recently symptomatic carotid stenosis patients in whom carotid end-
arterectomy is being considered, it is recommended that neurologists/stroke phy­sicians and vascular surgeons develop local protocols to specify preferred antiplatelet regimens (combination therapy vs. monotherapy), so as not to delay urgent carotid surgery.
• No. 58: For patients presenting with recent carotid territory symptoms and evi-
dence of free oating thrombus within the carotid artery, therapeutic anticoagu­lation is recommended.
• No. 63: For patients with a transient ischaemic attack or minor ischaemic stroke
in the presence of newly diagnosed or known atrial brillation and an ipsilateral

50–99% carotid stenosis, comprehensive neurovascular work up with multidisciplinary team review is recommended to determine whether urgent carotid revascularisation or anticoagulation alone is indicated.
• No. 64: For patients who have been started on anticoagulation (on the basis that
cardiac embolism was considered the most likely cause of their transient isch­aemic attack or stroke) but who then report recurrent event(s) in the territory ipsilateral to a 50–99% carotid stenosis whilst on therapeutic levels of anticoagu­lation, carotid endarterectomy or carotid artery stenting is recommended.
• No. 66: For patients undergoing carotid endarterectomy, it is recommended that
the operation be performed by trained vascular surgeons, rather than by surgeons from other specialties.
• No. 91: For patients experiencing a peri-operative stroke, it is recommended to
differentiate between an intra-operative and a post-operative stroke.
• No. 92: For patients who develop an ipsilateral neurological decit after ow is
restored following carotid clamp release when carotid endarterectomy is per­formed under locoregional anaesthesia, immediate re-exploration of the carotid artery is recommended.
• No. 93: For patients who develop an ipsilateral or contralateral stroke at any time
period following carotid endarterectomy or carotid artery stenting, urgent diag­nostic neurovascular imaging of both carotid arteries and the brain is recommended.

1.1.1.3 New Class IIa Recommendations
• No. 49: For patients with acute ischaemic stroke due to a symptomatic 50–99%
carotid stenosis who have received intravenous thrombolysis, delaying carotid endarterectomy or carotid stenting by 6 days following completion of throm­bolysis should be considered.
• No. 54: For recently symptomatic patients with 50–99% stenoses and contralat-
eral carotid occlusion or previous cervical radiation therapy, the choice of carotid endarterectomy or carotid artery stenting should be considered on an individ­ual basis.
• No. 62: For patients with conrmed ocular ischaemia syndrome and a 50–99%
ipsilateral carotid stenosis, carotid endarterectomy or carotid stenting should be considered to prevent further ischaemia induced retinal neovascularisation.
• No. 77: For patients undergoing carotid endarterectomy, intra-operative comple-
tion imaging with angiography, duplex ultrasound or angioscopy should be con­sidered in order to reduce the risk of peri-operative stroke.
• No. 82: For patients selected to undergo carotid artery stenting, transradial or
transcarotid artery revascularisation should be considered as an alternative to transfemoral carotid artery stenting, especially where transfemoral access may confer a higher risk of complications.

1 Extracranial Carotid Stenosis
• No. 83: For patients undergoing carotid artery stenting, decisions regarding stent
design (open cell, closed cell) should be considered at the discretion of the operator.
• No. 85: For patients undergoing carotid artery stenting, when pre-dilatation is
planned, balloon diameters <5mm should be considered in order to reduce the risk of peri-procedural stroke or transient ischaemic attack.
• No. 88: For patients undergoing carotid artery stenting, decisions regarding
choice of cerebral protection (lter, proximal ow reversal) should be considered at the discretion of the operator.
1.1.1.4 New Class IIb Recommendations
• No. 51: For a patient with acute ischaemic stroke undergoing intracranial
mechanical thrombectomy with a tandem 50–99% carotid stenosis and a small area of ipsilateral infarction, synchronous carotid stenting may be considered in the presence of poor antegrade internal carotid artery ow or poor collateralisa­tion via the circle of Willis after mechanical thrombectomy.
• No. 57: For patients with carotid near occlusion and distal vessel collapse with
recurrent carotid territory symptoms (despite best medical therapy), carotid end­arterectomy or carotid artery stenting may be considered only after multidisci­plinary team review.
• No. 59: For patients presenting with recent carotid territory symptoms and free
oating thrombus who develop recurrent symptoms whilst receiving anticoagu­lation therapy, surgical or endovascular removal of the thrombus may be considered.
• No. 61: For symptomatic patients with a carotid web [=shelf-like protrusions of
intimal brous tissue arising at the posterior wall of the carotid bulb/focal intimal variant of bromuscular dysplasia] in whom no other cause for stroke can be identied after detailed neurovascular work up, carotid endarterectomy or carotid artery stenting may be considered to prevent recurrent stroke.
• No. 90: For patients undergoing transfemoral carotid stenting, at least twelve
carotid stent procedures per year (per operator) may be considered an appropri­ate operator volume threshold to maintain optimal outcomes.
• No. 101: In selected high risk for surgery patients or emergency patients with
suspected prosthetic patch infection, insertion of a covered stent may be consid­ered, as part of the three stage EndoVAC technique.
1.1.1.5 Class III: Non-recommendations
• No. 60: For patients presenting with recent carotid territory symptoms and evi-
dence of free oating thrombus, intravenous thrombolysis is not recommended.
