Abstract
Importance Thromboembolic stroke attributable to an ipsilateral carotid artery plaque is a leading cause of disability in the United States and a major source of morbidity. Randomized clinical trials have demonstrated the efficacy of carotid endarterectomy and carotid stenting at minimizing stroke risk in patients with minor stroke and transient ischemic attack. However, there is no consensus on guidelines for medical management and the timing of revascularization in patients with multiple recurrent episodes of transient ischemic attack over hours or days, an acute neurological event known as crescendo transient ischemic attack. Objective To review the management of and timing of intervention in patients presenting with crescendo transient ischemic attack. Evidence Review This systematic review included all English-language articles published from January 1, 1985, to January 1, 2019, available from PubMed (MEDLINE) and Google Scholar. Articles were excluded if they did not include analysis of patients with symptoms, did not report the timing of intervention after crescendo transient ischemic attack, or mixed analysis of patients with stroke in evolution with patients with crescendo transient ischemic attack. The quality of the evidence was assessed with the modified rating from the Oxford Centre for Evidence-based Medicine. Observations Patients with crescendo transient ischemic attack were found to have a higher risk of stroke or death after carotid endarterectomy compared with patients with a single transient ischemic attack or stable stroke. With medical therapy alone, a considerable number of patients with crescendo transient ischemic attack experience a completed stroke within several months and have a poor prognosis without intervention. Urgent carotid endarterectomy, typically performed within 48 hours of initial presentation, is beneficial in carefully selected patients. There have been several reports of operative treatment within the first 24 hours of presentation; however, review of these reports does not show any additional benefit from emergency treatment. Carotid artery stenting is reserved only for selected patients with prohibitive surgical risk for endarterectomy. The literature does not clearly support any additional benefit of intravenous heparin therapy over mono or dual antiplatelet therapy prior to carotid endarterectomy. Conclusions and Relevance Crescendo transient ischemic attack is best managed with optimal medical management as well as urgent carotid endarterectomy within 2 days of presentation. Surgical endarterectomy appears to be preferred because of the increased embolic potential of bifurcation plaque, whereas stenting is an option for patients with contraindications for surgery. With ongoing advances in cerebrovascular imaging and medical treatment of stroke, there is a need for better evidence to determine the optimal timing and preoperative medical management of patients with crescendo transient ischemic attack.

Abstract
Abstract
Carotid revascularization has been recommended as the maximally beneficial treatment for stroke prevention in patients with recently symptomatic carotid stenosis (SCS). The appropriate timing for performing carotid endarterectomy (CEA) within the first 14 d after the occurrence of the index event remains controversial. We aim to provide a snapshot of the pertinent current literature related to the timing of CEA for patients with SCS. A systematic review of literature was conducted to study the timing of CEA for SCS. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) were followed. A total of 63 articles were identified as relevant to this topic. A summary of 15 articles favoring urgent CEA (within 48 h) for SCS within 48 h of index event and 9 articles not favoring urgent CEA is presented. A consensus is still to be achieved on the ideal timing of CEA for SCS within the 14-d window presently prescribed. The current literature suggests that patients who undergo urgent CEA (within 48 h) after nondisabling stroke as the index event have an increased periprocedural risk as compared to those who had transient ischemic attack (TIA) as the index event. Further prospective studies and clinical trials studying this question with separate groups classified as per the index event are required to shed more light on the subject. The current literature points to a changing paradigm towards early carotid surgery, specifically targeted within 48 h if the index event is TIA, and within 7 d if the index event is stroke.

Abstract
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.

Abstract
OBJECTIVE Carotid stenosis with crescendo-transient-ischemic-attack (cTIA) requires a prompt intervention to reduce the stroke risk. Few data are reported in literature about cTIA suggesting a different perioperative risk compared with patients with single TIA (sTIA). This study aimed to compare the outcome of carotid endarterectomy (CEA) in patients with TIA (single/crescendo) and evaluate the outcome risk-factors. METHODS Data from two tertiary hospitals for vascular treatment were analyzed from 2007 to 2016. All patients with TIA subjected to CEA were considered, comparing the 30-day postoperative stroke and stroke/death in patients with cTIA and sTIA, particularly in the urgent (≤48 h) setting. RESULTS On a total of 3866 CEA, 888 (23%) were performed in symptomatic patients and 515 for TIA: 365 (71%) patients with sTIA and 150 (29%) with cTIA. When compared with sTIA, cTIA patients were younger and less frequently affected by coronary disease, dyslipidemia, and chronic pulmonary disease; however, contralateral carotid occlusion was more common (20% vs. 10%, P = .004; 56% vs. 46, P = .03; 16% vs. 7%, P = .01; >80 years 26% vs. 16%, P = .01 and 2% vs. 10%, P = .001; respectively). Postoperative stroke and stroke/death were significantly higher in cTIA compared with sTIA (5.3% vs. 1.6%, P = .02 and 6.0% vs. 2.2%, P = .03; respectively). Urgent CEA was performed in 58% ( n: 87) cTIA and in 11% ( n: 56) sTIA( P<.01). The urgent setting did not influence the stroke and stroke/death rate of CEA for sTIA (3.6% vs. 1.3%, P = .21 and 3.6% vs. 1.9%, P = .44, respectively), but was associated with lower rate of events in cTIA (1.1%vs. 11.1%, P = .01 and 2.3% vs. 11.1%, P = .03, respectively). This beneficial effect in patients with cTIA treated within 48-h was confirmed also by multivariate analysis (OR: 0.09, 95% CI: 0.76-0.01, P=.02). CONCLUSIONS cTIA subjected to CEA have a higher stroke and stroke/death risk compared with patients with sTIA. The urgent setting seems to reduce the stroke/death rate cTIA; for sTIA with a stable neurological condition, the timing of CEA did not influence the outcome.

Summary of Evidence on Early Carotid Intervention for Recently Symptomatic Stenosis Based on Meta-Analysis of Current Risks. Stroke 2015; 46:3423-36. [DOI: 10.1161/strokeaha.115.010764] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2015] [Accepted: 09/14/2015] [Indexed: 12/16/2022]
Abstract
Background and Purpose—
This study aimed to assess the evidence on the periprocedural (<30 days) risks of carotid intervention in relation to timing of procedure in patients with recently symptomatic carotid stenosis.
Methods—
A systematic literature review of studies published in the past 8 years reporting periprocedural stroke/death after carotid endarterectomy (CEA) and carotid stenting (CAS) related to the time between qualifying neurological symptoms and intervention was performed. Pooled estimates of periprocedural risk for patients treated within 0 to 48 hours, 0 to 7 days, and 0 to 15 days were derived with proportional meta-analyses and reported separately for patients with stroke and transient ischemic attack as index events.
Results—
Of 47 studies included, 35 were on CEA, 7 on CAS, and 5 included both procedures. The pooled risk of periprocedural stroke was 3.4% (95% confidence interval [CI], 2.6–4.3) after CEA and 4.8% (95% CI, 2.5–7.8) after CAS performed <15 days; stroke/death rates were 3.8% and 6.9% after CEA and CAS, respectively. Pooled periprocedural stroke risk was 3.3% (95% CI, 2.1–4.6) after CEA and 4.8% (95% CI, 2.5–7.8) after CAS when performed within 0 to 7 days. In hyperacute surgery (<48 hours), periprocedural stroke risk after CEA was 5.3% (95% CI, 2.8–8.4) but with relevant risk differences among patients treated after transient ischemic attack (2.7%; 95% CI, 0.5–6.9) or stroke (8.0%; 95% CI, 4.6–12.2) as index.
Conclusions—
CEA within 15 days from stroke/transient ischemic attack can be performed with periprocedural stroke risk <3.5%. CAS within the same period may carry a stroke risk of 4.8%. Similar periprocedural risks occur after CEA and CAS performed earlier, within 0 to 7 days. Carotid revascularization can be safely performed within the first week (0–7 days) after symptom onset.

Abstract
BACKGROUND AND PURPOSE Symptomatic carotid stenosis (sCS), a common cause of transient ischemic attack (TIA), is correlated with higher stroke risk. We investigated the frequency and associated factors of sCS in patients with TIA and the association between sCS and stroke risk following TIA. METHODS Over a three-year period (2011-2013), 861 consecutive patients with TIA, who were admitted to the Department of Neurology at the University of Lübeck, Germany, were included in a monocenter study and prospectively evaluated. Diagnosis of TIA was in accordance with the tissue-based definition (transient neurological symptoms without evidence of infarction by brain imaging). RESULTS Of 827 patients (mean age, 70 ± 13.2 years; 49.7% women), 64 patients (7.7%; 95% confidence interval [CI], 5.9%-9.7%) exhibited sCS and 3 patients (0.3%) showed an occlusion of the corresponding internal carotid artery. Logistic regression revealed that sCS was associated with male sex (odds ratio [OR], 2.7; 95% CI, 1.2-3.6; p = 0.012), amaurosis fugax (OR, 8.1; 95% CI, 3.4-19-4; p < 0.001), unilateral weakness (OR, 3.4; 95% CI, 1.9-6.1; p < 0.001), symptom duration less than 1 h (OR, 2.0; 95% CI, 1.1-3.4; p = 0.019) and previous stroke (OR, 2.7; 95% CI, 1.5-4.7; p = 0.001). During hospitalization (mean, 6.6 days), five patients (0.6%; 95% CI, 0.1%-1.2%) suffered from stroke. The stroke risk was higher in patients with sCS than in those without sCS (6.3% vs. 0.1%; p < 0.001), whereas the recurrent TIA risk (2.6%) did not differ between the groups (4.7% vs. 2.5%; p = 0.29). CONCLUSION SCS appears to be associated with a higher risk of stroke in patients with TIA defined according to the tissue-based definition.

Abstract
BACKGROUND The aim of this study was to compare outcomes of early (<15 days) versus delayed carotid endarterectomy (CEA) in symptomatic patients. METHODS All CEA procedures performed for symptomatic carotid stenosis between January 2006 and May 2010 were retrospectively reviewed. Postoperative mortality (within 30 days), stroke, and myocardial infarction (MI) rates were analyzed in the early and delayed CEA groups. RESULTS During the study period, 149 patients were included. Carotid revascularization was performed within 15 days after symptom onset in 62 (41.6%) patients and longer than 15 days after symptom onset in 87 (58.4%) patients. The mean time lapse between onset of neurological symptoms and surgery was 9.3 days (range 1-15) in the early surgery group and 47.9 days (range 16-157) in the delayed surgery group. Thirty-day combined stroke and death rates were, respectively, 1.7% and 3.5% in the early and the delayed surgery groups. Thirty-day combined stroke, death, and MI rates were, respectively, 1.7% and 5.9% in the early and the delayed surgery groups. CONCLUSION During the study period, the reduction of the symptom-to-knife time in application to the carotid revascularization guidelines did not impact our outcomes suggesting that early CEA achieves 30-day mortality and morbidity rates at least equivalent to those of delayed CEA.

Abstract
OBJECTIVE This study examined the effect of acute ischemic stroke (AIS) care coordination between vascular surgery and stroke neurology services with primary focus on acute patient stabilization and expeditious carotid endarterectomy (CEA). METHODS A standardized AIS protocol was instituted between vascular surgery and stroke neurology services in an academic hospital (group I) that included: (1) rapid patient evaluation and imaging inclusive of brain and carotid computed tomography/magnetic resonance angiography, carotid duplex ultrasound imaging or conventional arteriogram, or both; (2) patient admission to a dedicated stroke unit with minimum 1:2 intensive care nurse-to-patient staffing and a 24-hour available neurointensivist; (3) treatment of all patients with ipsilateral moderate or severe carotid stenosis by CEA with cervical block (158 [81%]) or general anesthesia (38 [19%]). Patient exclusion from undergoing expeditious CEA included (1) stroke in evolution, and (2) dense neurologic deficit or National Institutes of Health Stroke Scale score >15 (severe), or both. Comparisons of data were performed between group I patients and those treated in outlying hospitals (group II) for similar indications. All data were prospectively collected in a computerized database and outcomes evaluated retrospectively. RESULTS From November 2002 to November 2012, 369 patients underwent CEA for AIS ≤1 week of presentation. There were 192 patients in group I and 177 in group II. There were no differences in group I and II in mean stroke-to-CEA interval (3.4 vs 3.9 days) or in the performance of eversion CEA (94% vs 97%), respectively. Intraoperative shunt use was greater in group I (28%) than in group II (18%; P = .021). Fewer total neurologic events (stroke or transient ischemic attack) occurred in group I (6 [3.1%] vs 14 [7.3%]; P = .03). No patients died in either group. Postoperative National Institutes of Health Stroke Scale scores available in group I patients showed improvement from preoperative baseline in mild and moderate stroke patients (P < .001). CONCLUSIONS In patients with stable acute stroke, early CEA is feasible and relatively safe. Stroke or death occurs in only 1%, and most complications are of nonfatal cardiac origin. A standardized stroke team protocol that is inclusive of stroke neurologists and vascular surgeons allows for expeditious and safe CEA in the setting of an acute stroke.

AORTA : OFFICIAL JOURNAL OF THE AORTIC INSTITUTE AT YALE-NEW HAVEN HOSPITAL 2013; 1:110-6.

Abstract
BACKGROUND To evaluate the feasibility and the safety of performing urgent (within 24 hours) carotid endarterectomy in patients with carotid stenosis presenting with repetitive transient ischemic attacks or progressing stroke. METHODS Thirty consecutive patients underwent urgent carotid endarterectomy for repetitive transient ischemic attacks (N = 12) or progressing stroke (N = 18) according to the following criteria: two or more transient ischemic attacks or a fluctuating neurological deficit over a period of less than 24 hours (progressing stroke), no impairment of consciousness, no cerebral infarct larger than 1.5 cm in diameter on computed tomography and a carotid artery stenosis of 70% or more on the appropriate side, diagnosed by echodoppler ultrasonography and/or arteriography. Patients with cerebral hemorrhage were excluded. All patients were examined pre- and postoperatively by the same neurologist and surgery was performed by the same vascular surgeon. All the patients underwent a cerebral CT scan within 5 days after surgery. RESULTS There were 19 men and 11 women. The mean age was 71 ± 7.6 years. The time delay of surgery after the onset of transient ischemic attacks or progressing stroke averaged 19.4 ± 11.5 hours. For patients suffering progressive stroke, one developed a fatal ischemic stroke 24 hours after surgery, five showed no improvement of their neurological status after surgery, but none worsened. Twelve patients experienced significant improvement of their neurological status with an European Stroke Scale of 77.9 ± 25.2 at admission and 95.8 ± 4.6 at discharge, and all but one of those patients had a Barthel's index value over 85/100 at discharge. The 12 patients with repetitive transient ischemic attacks had an uneventful postoperative outcome. The mean duration of follow-up was 3.4 ± 1.2 years. No patient developed another transient ischemic attack or ischemic stroke during the follow-up period. CONCLUSIONS The results of our series documented the feasibility and the safety of performing urgent (within 24 hours) carotid endarterectomy in patients presenting with repetitive transient ischemic attacks or progressing stroke. This procedure seems to us to be justified by the fact that waiting for surgery may lead to the development of a more profound deficit or another stroke in these neurologically unstable patients whose only chance for neurological recovery is in the early phase.

Abstract
BACKGROUND AND PURPOSE Patients with symptomatic carotid stenosis (sCS) have a higher risk of stroke recurrence following the first ischaemic event. Guidelines recommend that patients undergo carotid revascularization (CR), preferably within 2 weeks of the event. We aimed to determine the rate of stroke recurrence during hospitalization in patients who were admitted to the hospital with an acute ischaemic event and who underwent CR for recently sCS. METHODS As part of the stroke registry in Schleswig-Holstein, Germany (QugSS2; Qualitätsgemeinschaft Schlaganfallversorgung in Schleswig-Holstein), over a 4.5-year period (starting 2007) all patients (N = 15,797) who were admitted to the hospital with an acute cerebral ischaemic event were included and prospectively evaluated. RESULTS A total of 597 (3.8%) patients (mean age, 71 ± 10 years; 30% women) underwent a CR. The median time between symptom onset and admission to hospitals was 6 h. During the mean hospitalization of 10 days, 30 patients (5%) suffered a stroke. The rates of stroke recurrence were higher, albeit non-significantly, in men compared with women (6% vs. 2.3%, respectively; P = 0.059), and in patients admitted with ischaemic stroke compared with patients admitted with transient ischaemic attack (6.1% vs. 2%, respectively; P = 0.052). The risk of stroke recurrence did not show any association with the other demographic and clinical parameters. CONCLUSION The rate of stroke recurrence was 5% in patients with recently sCS who scheduled for CR. This suggests that CR should be performed immediately after presenting event to prevent stroke recurrence.

Abstract
Carotid stenoses of ≥50% account for about 15-20% of strokes. Their degree may be moderate (50-69%) or severe (70-99%). Current diagnostic methods include ultrasound, MR- or CT-angiography. Stenosis severity, irregular plaque surface, and presence of microembolic signals detected by transcranial Doppler predict the early recurrence risk, which may be as high as 20%. Initial therapy comprises antiplatelets and statins. Benefit of revascularization is greater in men, in older patients, and in severe stenosis; patients with moderate stenoses may also profit particularly if the plaque has an irregular aspect. An intervention should be performed within <2 weeks. In large randomized studies comparing endarterectomy and stenting, endovascular therapy was associated with a higher risk of periprocedural stroke, yet in some studies, with a lower risk of myocardial infarction and of cranial neuropathy. These trials support endarterectomy as the first choice treatment. Risk factors for each of the two therapies have been indentified: coronary artery disease, neck radiation, contralateral laryngeal nerve palsy for endarterectomy, and, elderly patients (>70 years), arch vessel tortuosity and plaques with low echogenicity on ultrasound for carotid stenting. Lastly, in direct comparisons, a contralateral occlusion increases the risk of periprocedural complications in both types of treatment.
