Safety of urgent endarterectomy in acute non-disabling stroke patients with symptomatic carotid artery stenosis: an international multicenter study.

BACKGROUND AND PURPOSE: International recommendations advocate that carotid endarterectomy (CEA) should be performed within 2 weeks from the index event in symptomatic carotid artery stenosis (sCAS) patients. However, there are controversial data regarding the safety of CEA performed during the first 2 days of ictus. The aim of this international, multicenter study was to prospectively evaluate the safety of urgent (0-2 days) in comparison to early (3-14 days) CEA in patients with sCAS. METHODS: Consecutive patients with non-disabling (modified Rankin Scale scores ≤2) acute ischaemic stroke or transient ischaemic attack due to sCAS (≥70%) underwent urgent or early CEA at five tertiary-care stroke centers during a 6-year period. The primary outcome events included stroke, myocardial infarction or death during the 30-day follow-up period. RESULTS: A total of 311 patients with sCAS underwent urgent (n = 63) or early (n = 248) CEA. The two groups did not differ in baseline characteristics with the exception of crescendo transient ischaemic attacks (21% in urgent vs. 7% in early CEA; P = 0.001). The 30-day rates of stroke did not differ (P = 0.333) between patients with urgent (7.9%; 95% confidence interval 3.1%-17.7%) and early (4.4%; 95% confidence interval 2.4%-7.9%) CEA. The mortality and myocardial infarction rates were similar between the two groups. The median length of hospitalization was shorter in urgent CEA [6 days (interquartile range 4-6) vs. 10 days (interquartile range 7-14); P < 0.001]. CONCLUSIONS: Our findings highlight that urgent CEA performed within 2 days from the index event is related to a non-significant increase in the risk of peri-procedural stroke. The safety of urgent CEA requires further evaluation in larger datasets.

Safety of early endarterectomy in patients with symptomatic carotid artery stenosis: an international multicenter study.

BACKGROUND AND PURPOSE: Although the latest recommendations suggest that carotid endarterectomy (CEA) should be performed in symptomatic carotid artery stenosis (sCAS) patients within 2 weeks of the index event, only a minority of patients undergo surgery within the recommended time-frame. The aim of this international multicenter study was to prospectively evaluate the safety of early CEA in patients with sCAS in everyday clinical practice settings. METHODS: Consecutive patients with non-disabling acute ischaemic stroke (AIS) or transient ischaemic attack (TIA) due to sCAS (≥ 70%) underwent early (≤ 14 days) CEA at five tertiary-care stroke centers during a 2-year period. Primary outcome events included stroke, myocardial infarction (MI) or death occurring during the 30-day follow-up period and were defined according to the International Carotid Stenting Study criteria. RESULTS: A total of 165 patients with sCAS [mean age 69 ± 10 years; 69% men; 70% AIS; 6% crescendo TIA; 8% with contralateral internal carotid artery (ICA) occlusion] underwent early CEA (median elapsed time from symptom onset 8 days). Urgent CEA (≤ 2 days) was performed in 20 cases (12%). The primary outcomes of stroke and MI were 4.8% [95% confidence interval (CI) 1.5%-8.1%] and 0.6% (95% CI 0%-1.8%). The combined outcome event of non-fatal stroke, non-fatal MI or death was 5.5% (95% CI 2.0%-9.0%). Crescendo TIA, contralateral ICA occlusion and urgent CEA were not associated (P > 0.2) with a higher 30-day stroke rate. CONCLUSIONS: Our findings indicate that the risk of early CEA in consecutive unselected patients with non-disabling AIS or TIA due to sCAS is acceptable when the procedure is performed within 2 weeks (or even within 2 days) from symptom onset.

Cerebral malaria is one of the most serious complications of Plasmodium falciparum infection, this protozoa of the Plasmodium family is the only known to induce cerebral malaria. This case is about a frontal lobe syndrome post cerebral malaria in a young man living in an endemic malaria area. This complication is rare and most common during childhood.
