Long-term follow-up study of endarterectomy versus angioplasty in patients with symptomatic severe carotid stenosis trial.

BACKGROUND AND PURPOSE: We aimed at comparing the long-term benefit-risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis. METHODS: Long-term follow-up study of patients included in Endarterectomy Versus Angioplasty in Patients With Symptomatic Severe Carotid Stenosis (EVA-3S), a randomized, controlled trial of carotid stenting versus endarterectomy in 527 patients with recently symptomatic severe carotid stenosis, conducted in 30 centers in France. The main end point was a composite of any ipsilateral stroke after randomization or any procedural stroke or death. RESULTS: During a median follow-up of 7.1 years (interquartile range, 5.1-8.8 years; maximum 12.4 years), the primary end point occurred in 30 patients in the stenting group compared with 18 patients in the endarterectomy group. Cumulative probabilities of this outcome were 11.0% (95% confidence interval, 7.9-15.2) versus 6.3% (4.0-9.8) in the endarterectomy group at the 5-year follow-up (hazard ratio, 1.85; 1.00-3.40; P=0.04) and 11.5% (8.2-15.9) versus 7.6% (4.9-11.8; hazard ratio, 1.70; 0.95-3.06; P=0.07) at the 10-year follow-up. No difference was observed between treatment groups in the rates of ipsilateral stroke beyond the procedural period, severe carotid restenosis (≥70%) or occlusion, death, myocardial infarction, and revascularization procedures. CONCLUSIONS: The long-term benefit-risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis favored endarterectomy, a difference driven by a lower risk of procedural stroke after endarterectomy. Both techniques were associated with low and similar long-term risks of recurrent ipsilateral stroke beyond the procedural period. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Migraine with aura in patients over 50 years of age: the Marseille's registry.

The goal of this study was to describe specifically the clinical characteristics of migraine with aura inpatients over the age of 50. During 1 year, three neurologists working in a tertiary headache center included all patients aged 50 years and over presenting migraine with aura in a prospective registry. Fifty-seven patients with migraine with aura aged 50 years and over were interviewed using a standardized questionnaire during a consultation. Auras were visual for all the patients, paresthesic for 16 patients, and aphasic for 16. One patient had a sporadic hemiplegic migraine. The headache followed the aura in a large majority of patients and fulfilled the International Headache Society criteria for migraine headache for 38 patients. Typical aura without headache was described in 26 patients and was the only expression of the disease for five patients. Two groups can be defined: in the first one, migraine with aura began before 50 years (39 patients). Thirty-one patients had typical aura with migraine headache and 15 complained of typical aura without headache. The second group (18 patients) included patients who developed migraine with aura over 50 for the first time. Among them, patients may have typical aura with migraine headache (seven patients), typical aura with non-migraine headache (eight patients) and/or typical aura without headache (11 patients). Late-life onset transient visual phenomena are not rare. These symptoms may occur for the first time after 50, in the absence of headache. When migraine with aura began after 50 years, headache has more often the characteristics of typical aura with nonmigraine headache, or migraine may have the presentation of typical migraine without headache.

Impact of cerebrovascular complications on mortality and neurologic outcome during infective endocarditis: a prospective multicentre study.

AIMS: To analyse the risk of death according to the type of cerebrovascular complications (CVC) during infective endocarditis (IE) and to analyse the determinants of outcome in patients with IE and a CVC. METHODS AND RESULTS: In two referral centres, 496 consecutive patients with definite IE were prospectively included. Cerebral CT scan was performed in 453 patients. During a mean 2.9 year follow-up, 139 (28%) patients died and CVC occurred in 109 (22%) patients. Stroke was an independent predictor of death, although no significant excess mortality was observed in patients with silent CVC or transient ischaemic attack (TIA). Among CVC patients, mortality was predicted by the presence of a mechanical prosthetic valve IE and a low Glasgow Coma Scale. When valvular surgery was performed in patients after CVC, neurologic exacerbation was rare [4 (6.3%) patients] and was observed only in patients with symptomatic stroke. Among CVC patients, survival was better in operated patients when compared with patients treated conservatively despite theoretical indication for surgery (P < 0.0001). However, the latter group had more comorbidities (P = 0.007) and a lower Glasgow Coma Scale (14.6 +/- 1 vs. 12 +/- 4, P < 0.0001). CONCLUSION: Patients with silent CVC or TIA have a relatively good prognosis, whereas those with stroke have significant excess mortality particularly in case of mechanical prosthetic valve IE or impaired consciousness. Valvular surgery can be safely performed after silent CVC or TIA and may improve survival in selected patients with stroke.
