Scientific titleStent-protected Percutaneous Angioplasty of the Carotid artery versus Endarterectomy
Study acronymSPACE
Study hypothesisTo compare carotid endarterectomy (CEA) and carotid stenting in patients with symptomatic >70% carotid artery stenosis.
To prove equivalence in the treatment of symptomatic >70% carotid artery stenosis in:
a. Prevalence of ipsilateral stroke (modified Rankin ≥4) or death at 30 days
b. Prevalence of ipsilateral stroke or death within 24 months after randomisation
c. Restenosis (>70%) according to North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria at 6, 12, 24 months
d. Procedural failure: technical or serious adverse events (SAE), subacute occlusion, (re)stenosis of 70% NASCET within 7 days
e. Prevalence of any stroke within 30 days and 2 years after randomisation
Ethics approval(s)Not provided at time of registration
ConditionStroke, secondary prevention
InterventionCarotid endarterectomy or Carotid artery stenting
Intervention typeOther
Primary outcome measureOccurrence of an ipsilateral stroke (ischaemic stroke and/or intracerebrale bleeding with symptoms lasting more than 24 hours) or the death of every cause, between randomisation and day 30
Secondary outcome measures1. Ipsilateral stroke (ischaemic stroke and/or intracerebral bleeding) or vascular death within the follow-up period of 24 months, beginning with the time of randomisation
2. Restenosis with at least 70% measured by Duplexsonography according to 70%-stenosis following the ECST-criteria or at least a 50%-stenosis after the criteria of the NASCET after 6, 12 and 24 months
3. Procedural technical failure (technically not feasible treatment, serious adverse events [SAE] during and/or by the treatment, occlusion of the vessel or restenosis with at least 70% measured by Duplexsonography according to 70%-stenosis following the ECST-criteria or at least a 50%-stenosis after the criteria of the NASCET on the 6th day ± 1 day and 30th day ± 3 day after treatment)
4. Ipsilateral stroke (ischaemic stroke and/or intracerebral bleeding with an impairment ≥3 on the modified Rankin scale) or death of every cause, between randomisation and day 30 ± 3 after treatment
5. Strokes of every localisation and severity 30 ± 3 days after the intervention
6. Strokes of every localisation and severity within 24 months ± 14 days after the intervention
