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
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
Ischemic stroke may occur in patients in whom vascular imaging shows the ipsilateral internal carotid artery (ICA) to be occluded. In younger patients this is often due to carotid artery dissection, while in older people this most likely results from cardiac embolism or thrombosis secondary to high-grade stenosis at the carotid bifurcation. Interventional techniques aim at recanalization of the carotid artery for early restoration of cerebral blood flow and secondary prevention of future strokes. In chronic ICA occlusion the ischemic infarct may be related to hemodynamic compromise. In this situation, extracranial-intracranial bypass surgery was introduced, but its role remains still unclear. Ischemic stroke may also occur in patients with a chronic occlusion of the contralateral ICA. This situation demands the usual stroke treatment, but surgical and neuroradiological interventions face a higher risk than unilateral vascular pathology. Medical treatment supports stroke prevention in carotid artery occlusion.

Abstract
Acute ischemic stroke is the fourth leading cause of death and the leading cause of disability in the United States. Stroke is a medical emergency. The development of stroke systems of care has changed the way practitioners view and treat this devastating disease. Ample evidence has shown that patients presenting early and receiving intravenous thrombolytic therapy have the best chance for significant improvement in functional outcome, particularly if they are transported to specialized stroke centers. Early detection and management of medical and neurologic complications is key at preventing further brain damage in patients with acute ischemic stroke.

Abstract
Object
The risk of recurrence of cerebrovascular events within the first 72 hours of admission in patients hospitalized with symptomatic carotid artery (CA) stenoses and the risks and benefits of emergency CA intervention within the first hours after the onset of symptoms are not well known. Therefore, the authors aimed to assess 1) the ipsilateral recurrence rate within 72 hours of admission, in the period from 72 hours to 7 days, and after 7 days in patients presenting with nondisabling stroke, transient ischemic attack (TIA), or amaurosis fugax (AF), and with an ipsilateral symptomatic CA stenosis of 50% or more, and 2) the risk of stroke in CA interventions within 48 hours of admission versus the risk in interventions performed after 48 hours.
Methods
Ninety-four patients were included in this study. These patients were admitted to hospital within 48 hours of a nondisabling stroke, TIA, or AF resulting from a symptomatic CA stenosis of 50% or more. The patients underwent carotid endarterectomy (85 patients) or CA stenting (9 patients). At baseline, the cardiovascular risk factors of the patients, the degree of symptomatic CA stenosis, and the type of secondary preventive treatment were assessed. The in-hospital recurrence rate of stroke, TIA, or AF ipsilateral to the symptomatic CA stenosis was determined for the first 72 hours after admission, from 72 hours to 7 days, and after 7 days. Procedure-related cerebrovascular events were also recorded.
Results
The median time from symptom onset to CA intervention was 5 days (interquartile range 3.00–9.25 days). Twenty-one patients (22.3%) underwent CA intervention within 48 hours after being admitted. Overall, 15 recurrent cerebrovascular events were observed in 12 patients (12.8%) in the period between admission and CA intervention: 3 strokes (2 strokes in progress and 1 stroke) (3.2%), 5 TIAs (5.3%), and 1 AF (1.1%) occurred within the first 72 hours (total 9.6%) of admission; 1 TIA (1.1%) occurred between 72 hours and 7 days, and 5 TIAs (5.3%) occurred after more than 7 days. The corresponding actuarial cerebrovascular recurrence rates were 11.4% (within 72 hours of admission), 2.4% (between 72 hours and 7 days), and 7.9% (after 7 days). Among baseline characteristics, no predictive factors for cerebrovascular recurrence were identified.
Procedure-related cerebrovascular events occurred at a rate of 4.3% (3 strokes and 1 TIA), and procedures performed within the first 48 hours and procedures performed after 48 hours had a similar frequency of these events (4.5% vs 4.1%, respectively; p = 0.896).
Conclusions
The in-hospital recurrence of cerebrovascular events was quite low, but all recurrent strokes occurred within 72 hours. The risk of stroke associated with a CA intervention performed within the first 48 hours was not increased compared with that for later interventions. This raises the question of the optimal timing of CA intervention in symptomatic CA stenosis. To answer this question, more data are needed, preferably from large randomized trials.

Outcomes of urgent carotid endarterectomy for stable and unstable acute neurologic deficits. J Vasc Surg 2013; 59:440-6.

Abstract
OBJECTIVE The aim of the study was to assess the outcomes of carotid endarterectomy (CEA) performed in an urgent setting on acutely symptomatic patients selected through a very simple protocol. METHODS From January 2002 to January 2012, 193 symptomatic patients underwent CEA. Of these, 90 presented with acute symptoms, and after a congruous carotid stenosis was identified, underwent urgent operations (group 1): 27 patients had transient ischemic attack (group 1A), 52 patients had mild to moderate stroke (group 1B), and 11 patients had stroke in evolution (group 1C). The remaining 103 patients with a nonrecent neurologic deficit were treated by elective surgery in the same period (group 2). End points were 30-day neurologic morbidity and mortality. RESULTS The median delay of urgent CEA (U-CEA) from deficit onset was 48 hours (interquartile range, 13-117 hours). Groups 1 and 2 were comparable in demographics. Acute patients showed a higher rate of stroke at presentation (70% vs 37%; P = .001) and of history of coronary artery disease (30% vs 13.5%; P = .007). Acute patients sustained six postoperative strokes (6.6%). Neurologic outcomes were correlated to clinical presentation: no strokes occurred in group 1A patients, and 5.8% group 1B patients and 27.3% group 1C patients had postoperative stroke (P < .01). Postoperative mortality was 4.4% for U-CEA: one fatal myocardial infarction, one intracranial hemorrhage, and two thromboembolic strokes. Elective patients sustained four postoperative strokes (3.9%), with one death (0.9%) as a consequence of hyperperfusion cerebral edema. U-CEAs performed ≤48 hours from symptom onset had a lower postoperative stroke rate than those performed >48 hours (4.4% vs 8.8%; P = .3). Among patients presenting with a stroke (group 1B), the National Institutes of Health Stroke Scale (NIHSS) assessment at discharge showed improvement in 79% (although only 25% had ≥4 points in reduction), stability in 17%, and deterioration in 4%. Patients with moderate stroke were slightly better in NIHSS improvement than those with mild stroke (median NIHSS variation at discharge, -3 vs -1; P = .001). CONCLUSIONS Our results with U-CEA confirm that this population has a higher risk profile compared with elective surgery. The type of acute presentation is correlated with perioperative risk. U-CEA was safe when performed on patients presenting with transient ischemic attack. An acceptable complication rate was achieved for patients with minor to moderate strokes. The poorest outcomes occurred in patients presenting with stroke in evolution: U-CEA in these patients should be offered with extreme caution, although we are aware that a conservative treatment may not grant a better prognosis.

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 The authors present an overview of the current evidence and management recommendations for evaluation and treatment of adults with acute ischemic stroke. The intended audiences are prehospital care providers, physicians, allied health professionals, and hospital administrators responsible for the care of acute ischemic stroke patients within the first 48 hours from stroke onset. These guidelines supersede the prior 2007 guidelines and 2009 updates. METHODS Members of the writing committee were appointed by the American Stroke Association Stroke Council's Scientific Statement Oversight Committee, representing various areas of medical expertise. Strict adherence to the American Heart Association conflict of interest policy was maintained throughout the consensus process. Panel members were assigned topics relevant to their areas of expertise, reviewed the stroke literature with emphasis on publications since the prior guidelines, and drafted recommendations in accordance with the American Heart Association Stroke Council's Level of Evidence grading algorithm. RESULTS The goal of these guidelines is to limit the morbidity and mortality associated with stroke. The guidelines support the overarching concept of stroke systems of care and detail aspects of stroke care from patient recognition; emergency medical services activation, transport, and triage; through the initial hours in the emergency department and stroke unit. The guideline discusses early stroke evaluation and general medical care, as well as ischemic stroke, specific interventions such as reperfusion strategies, and general physiological optimization for cerebral resuscitation. CONCLUSIONS Because many of the recommendations are based on limited data, additional research on treatment of acute ischemic stroke remains urgently needed.

Abstract
Patients with symptomatic tight carotid stenosis have an increased short-time risk of stroke and an increased long-term risk of ischaemic vascular events compared with the general population. The aim of this study is to assess the safety, efficacy, and limitations of urgent CEA or CAS, in patients with carotid stenosis greater than 70% and clinically characterized by recurrent TIA or brain damage following a stroke (<2.5 cm). This study involved 28 patients divided into two groups. Group A consisted of sixteen patients who had undergone CEA, and group B consisted of twelve patients who had undergone CAS. Primary endpoints were mortality, neurological morbidity (by NIHSS) and postoperative hemorrhagic cerebral conversion, at 30 days. Ten patients (62.5%) of group A experienced an improvement in their initial neurological deficit while in 4 cases (26%) the deficit remained stable. Two cases of neurologic mortality are presented. At 1 month, 9 patients (75%) of group B experienced an improvement in their initial neurological deficit while 3 patients (25%) had a neurological impairment. Urgent or deferred surgical or endovascular treatment have a satisfactory outcome considering the profile in very high-risk patient population. Otherwise in selected patients CEA seems to be preferred to CAS.

Abstract
Background and Purpose—
Reliable data on the risk of carotid endarterectomy (CEA) in relation to timing of surgery are necessary to plan CEA most effectively, to adjust risks for case-mix, and to understand the mechanisms of operative stroke.
Methods—
We performed a systematic review of all studies published from 1980 to 2008 inclusive that reported the risk of stroke and death due to CEA in relation to the time between presenting symptom and surgery. Pooled estimates of risk by the time since the last event were obtained by Mantel–Haenszel meta-analysis.
Results—
Of 494 published operative series, only 47 stratified risk by timing of surgery. The pooled absolute risks of stroke and death after urgent CEA were high in patients with stroke-in-evolution (20.2%, 95% CI 12.0 to 28.4) and in patients with crescendo TIA (11.4%, 6.1 to 16.7), with no trends toward reduced risks in more recent studies. However, there was no significant difference between early and later CEA in neurologically stable patients with recent TIA or nondisabling stroke (<1 week versus ≥1 week, OR=1.2, 0.9 to 1.7,
P
=0.17; <2 weeks versus ≥2 weeks, OR=1.2, 0.9 to 1.6,
P
=0.13).
Conclusions—
Emergency endarterectomy for stroke-in-evolution has a high operative risk, but the risk may be somewhat lower in patients with crescendo TIA. Surgery in the first week in neurologically stable patients with TIA or minor stroke is not associated with a substantially higher operative risk than delayed surgery. More data are required on the risk and benefit of more urgent surgery for TIA and minor stroke and for early versus delayed surgery in patients with major nondisabling stroke.

Abstract
We reviewed our experience with urgent carotid intervention in the setting of acute neurological deficits. Between June 1992 and August 2008, a total of 3145 carotid endarterectomies (CEA) were performed. Twenty-seven patients (<1.0%) were categorized as urgent. The mean age was 74.1 years (range 56-93 years) with 16 (60%) men, and 11 (40%) women, Symptoms included extremity weakness or paralysis (n = 13), amaurosis fugax (n = 6), speech difficulty (n = 2), and syncope, (n = 3). Three patients exhibited a combination of these symptoms. Three open thrombectomy were performed. Regional anesthesia was used in 13 patients (52%). Seventeen patients (67%), required shunt placement. At 30-days, 2 patient (7%) suffered a stroke, and 1 (4%) died. Urgent CEA can be performed safely. A stroke rate of 7% is acceptable in those who may otherwise suffer a dismal outcome without intervention.

Abstract
Current evidence suggests that carotid endarterectomy (CEA) performed within 2 weeks of symptoms produces better long-term results than if it is delayed. Urgent endarterectomy following unstable presentations such as crescendo transient ischemic attack (cTIA) or progressive stroke has been associated with variable results. The evidence for this treatment strategy required reviewing. A systematic review of articles related to urgent CEA between 1980 and 2008 was performed. For cTIA, there was an odds ratio of 5.6 (95% confidence interval 3.3–9.7, p ≤ .0001) for combined stroke or death compared with surgery for “standard” indications. For unstable stroke, the odds ratio was 5.5 (95% confidence interval 3.1–9.3, p ≤ .0001). Patients with unstable neurologic presentations are at higher risk of complications if operated on urgently. Clearer definitions would help more precise patient selection to avoid inadvertently operating on patients with an unacceptably high risk of poor outcome.

Abstract
BACKGROUND Computed tomography (CT) and magnetic resonance imaging (MRI) are tools of investigation in acute stroke. We wondered if the additional information offered by MRI outweighs the disadvantage of its longer scanning duration for systemic thrombolysis. METHODS Two hundred ninety-four consecutive patients (66 +/- 13 years) were subjected to thrombolysis between 1999 and 2004. Inclusion criteria were ischemic infarction, scoring at entry and discharge with the NIH stroke scale and modified Rankin scale, systemic thrombolysis within 3 hours after symptom onset, multimodal MRI or standard CT. Subgroup analysis of 42 patients compared standard CT with CT and CT angiography. RESULTS Patients were similarly affected on admission (P > .1). At discharge, 6 days after stroke onset, the patients investigated with MRI were less impaired than those investigated with standard CT (P < .05). Symptomatic hemorrhage was rare in both groups. Also, patients investigated with CT and CT angiography were less impaired at discharge than those with standard CT (P < .02). A multifactorial regression showed that systolic blood pressure, glucose level and initial neurological impairment determined the neurological outcome at discharge. CONCLUSIONS Systolic blood pressure, glucose level and neurological impairment but not the imaging modality determined the neurological outcome following systemic thrombolysis in the 3-hour window.

Abstract
BACKGROUND Epidemiologic studies suggest sex differences in evaluation of patients presenting with ischemic stroke. Sex differences in stroke evaluation could lead to sex differences in the validity of diagnosing ischemic stroke subtypes. This study assessed sex differences in the Ischemic Stroke Genetics Study (ISGS). METHODS The ISGS is a prospective case-control genetic association study of patients with first-ever ischemic stroke at 5 US tertiary stroke centers. The diagnostic tests performed as part of medical care were recorded for each enrolled patient. RESULTS A total of 505 patients were enrolled; 45% (229 of 505) were women and 55% (276 of 505) were men. Mean age at time of stroke was greater for women (66.6 v 61.9 years; P = .001). Frequency of brain computed tomography was 92% (254 of 276) for men and 90% (206 of 229) for women (P = .42). Magnetic resonance imaging was completed in 84% (232 of 276) of men and 83% (191 of 229) of women (P = .91). Frequency of electrocardiography was 91% (252 of 276) for men and 90% (206 of 229) for women (P = .60). Echocardiography was done in 74% (203 of 276) of men and 79% (180 of 229) of women (P = .19). Cervical arterial imaging occurred in 91% (208 of 229) of women and 86% (237 of 276) of men (P = .09). Intracranial vascular imaging was performed in 75% (207 of 276) of men and 79% (181 of 229) of women (P = .28). CONCLUSIONS Our findings suggest no significant sex differences in the extent to which major diagnostic tests were performed in patients in ISGS. Dedicated tertiary stroke centers may reduce the sex bias in stroke evaluation that has been identified by previous studies.

Abstract
BACKGROUND AND PURPOSE We examined indications for emergent revascularisation of acutely occluded internal carotid artery (ICA) using current diagnostic methods. MATERIAL AND METHODS From 1997 to 2006 we prospectively followed 34 consecutive patients undergoing emergency revascularisation due to acute extracranial ICA occlusion and acute ischaemic stroke within 72 h after symptom onset (mean 25) and within 36 h after admission (mean 16). Exclusion criteria were occlusion of the intracranial ICA or ipsilateral middle cerebral artery (MCA), ischaemic infarction of more than one third of the MCA perfusion area, or reduced level of consciousness. All patients underwent duplex sonography, cerebral CT, and/or MRI and angiography (MRA and/or DSA). We performed endarterectomy and thrombectomy of the ICA. RESULTS Confirmed by postoperative duplex sonography at discharge, ICA revascularisation was successful in 30 (88%) of 34 cases. Postoperative intracranial haemorrhage was detected in two patients (6%) and perioperative reinfarction in one (3%). Compared to the preoperative status, 20 patients (59%) showed signs of clinical improvement by at least one point on the Rankin scale, ten patients (29%) remained stable, and two patients (6%) had deteriorated. The 30-day mortality was 6% (two patients). CONCLUSION After careful diagnostic workup, revascularisation of acute extracranial ICA occlusion is feasible with low morbidity and mortality.

Abstract
BACKGROUND AND PURPOSE In middle cerebral artery (MCA) stroke, ischemia usually is unevenly distributed within the MCA territory. We sought to investigate which brain structures are critical for the acute neurological deficit in severe MCA stroke. METHODS We used magnetic resonance (MR) imaging and statistical parametric mapping in 64 consecutive stroke patients (64 +/-13 years) to study the pattern of the initial perfusion abnormality. RESULTS Patients with lesion progression had more severe time-to-peak (TTP) abnormalities (P < .0001) in the inferior frontal gyrus, superior temporal gyrus, insula, and underlying hemispheric white matter than those with lesion regression. Also, patients with lesion progression had more severe T2 abnormalities on day 8 than those with lesion regression. In contrast, the changes of water diffusion were similar among the two groups resulting in a perfusion-diffusion mismatch in lesion progression. TTP-lesions were related to the neurological deficit score (r(s)=-0.563, P < .0001), T2-lesions (r= 0.686, P < .0001), and cerebral artery abnormalities assessed on MR-angiography (r(s)= 0.399, P < .01). CONCLUSIONS In major MCA, stroke ischemia was most severe in the central portion of the MCA territory. It is suggested that involvement of hemispheric white matter accentuated the neurological deficit probably by affecting cortico-cortical and cortico-subcortical fibers.

Abstract
OBJECTIVE This study audited operative risk in patients undergoing urgent carotid surgery for crescendo transient ischemic attacks (TIAs). METHODS Interrogation of the vascular unit database (January 1992 to July 2004) identified 42 patients operated on urgently for crescendo TIAs, which were defined as>or=3 TIAs within the preceding 7 days. Stroke, death, and any major cardiac events were analyzed. RESULTS Thirty-nine patients underwent conventional endarterectomy, and three underwent interposition vein bypass. Crescendo TIA patients had sustained a median of five TIAs (range, 3 to 20) in the 7 days before surgery. Three patients died or had a stroke after surgery, for a combined stroke/death rate of 7%. This compares with 2.4% in 1000 patients undergoing elective carotid endarterectomy in this unit during the same time period. The combined stroke/death/major cardiac event rate was 14% (n=6). CONCLUSIONS The combined risk of neurologic and cardiac complications after urgent carotid surgery for crescendo TIA is higher than that expected after elective cases but is still acceptable considering the natural history of patients with unstable neurologic symptoms.

Abstract
Purpose—
Our goal is to provide an overview of the current evidence about components of the evaluation and treatment of adults with acute ischemic stroke. The intended audience is physicians and other emergency healthcare providers who treat patients within the first 48 hours after stroke. In addition, information for healthcare policy makers is included.
Methods—
Members of the panel were appointed by the American Heart Association Stroke Council’s Scientific Statement Oversight Committee and represented different areas of expertise. The panel reviewed the relevant literature with an emphasis on reports published since 2003 and used the American Heart Association Stroke Council’s Levels of Evidence grading algorithm to rate the evidence and to make recommendations. After approval of the statement by the panel, it underwent peer review and approval by the American Heart Association Science Advisory and Coordinating Committee. It is intended that this guideline be fully updated in 3 years.
Results—
Management of patients with acute ischemic stroke remains multifaceted and includes several aspects of care that have not been tested in clinical trials. This statement includes recommendations for management from the first contact by emergency medical services personnel through initial admission to the hospital. Intravenous administration of recombinant tissue plasminogen activator remains the most beneficial proven intervention for emergency treatment of stroke. Several interventions, including intra-arterial administration of thrombolytic agents and mechanical interventions, show promise. Because many of the recommendations are based on limited data, additional research on treatment of acute ischemic stroke is needed.

The intended audience is physicians and other emergency healthcare providers who treat patients within the first 48 hours after stroke. In addition, information for healthcare policy makers is included. METHODS Members of the panel were appointed by the American Heart Association Stroke Council's Scientific Statement Oversight Committee and represented different areas of expertise. The panel reviewed the relevant literature with an emphasis on reports published since 2003 and used the American Heart Association Stroke Council's Levels of Evidence grading algorithm to rate the evidence and to make recommendations. After approval of the statement by the panel, it underwent peer review and approval by the American Heart Association Science Advisory and Coordinating Committee. It is intended that this guideline be fully updated in 3 years. RESULTS Management of patients with acute ischemic stroke remains multifaceted and includes several aspects of care that have not been tested in clinical trials. This statement includes recommendations for management from the first contact by emergency medical services personnel through initial admission to the hospital. Intravenous administration of recombinant tissue plasminogen activator remains the most beneficial proven intervention for emergency treatment of stroke. Several interventions, including intra-arterial administration of thrombolytic agents and mechanical interventions, show promise. Because many of the recommendations are based on limited data, additional research on treatment of acute ischemic stroke is needed.

Abstract
PURPOSE To determine whether the perfusion deficit could predict brain infarction in patients with chronic cerebral ischemia who experienced recurring episodes of neurological symptoms and showed a perfusion-diffusion mismatch on magnetic resonance (MR) images. MATERIALS AND METHODS In 53 consecutive patients (38 males and 15 females, 62+/-13 years old) with ischemia in the middle cerebral artery (MCA) territory, lesion volumetry was performed on parametric maps of the time-to-peak, the cerebral blood volume, and diffusion-weighted (DW) images. The infarct lesions were assessed on follow-up T2-weighted (T2W) MR images after eight days. Cerebrovascular changes were determined by time-of-flight (TOF) MR angiography (MRA). Inferential and correlation statistics were used. RESULTS Patients with chronic ischemic brain disease (N=39) who presented with a severe perfusion-diffusion mismatch in the presence of a normal cerebral blood volume had no or small brain infarctions as found on follow-up T2W images. MRA revealed widespread abnormalities of the basal cerebral arteries compatible with brain perfusion abnormalities. In contrast, in acute stroke patients (N=14) the deficit of cerebral perfusion predicted the infarct lesion in the T2W images. CONCLUSION Our results suggest that in chronic cerebral ischemia the normal blood volume was maintained despite the depression of cerebral perfusion and recurring minor insults.

Abstract
Despite the earlier accepted notion that CEA should be delayed 4 to 6 weeks after a stroke, current evidence suggests that CEA may be performed safely earlier than this in most patients who have mild to moderate deficits once symptoms stabilize. The gray areas, however, remain gray, as outlined. Crescendo TIAs are urgent cases in the authors' practice; others advocate a more moderate delayed approach in such cases. Almost everyone agrees that propagating intraluminal thrombus is treated best with a moderate delayed approach that allows the thrombus to resolve first with anticoagulants. Acute carotid occlusion must be assessed on an individual basis: cases that occlude under observation should be explored immediately; cases that come from the field with profound deficits have dismal outcomes, but even here surgery may be effective in salvaging a small group of good functional survivors, and the natural history without surgery is atrocious. Surgery for stroke in evolution is associated with higher morbidity and mortality rates; selected patients may benefit from emergency surgery. A final thought is that for patients who have routine TIA or small stroke, with minimal imaging evidence of infarction or mass effect, a stable deficit, and a normal level of consciousness, there is no reason to empirically delay carotid reconstruction, and patients are served best by a fast-track approach to surgical treatment.

Abstract
OBJECTIVES To evaluate safety of early carotid endarterectomy (CEA) in patients with acute brain ischemia presenting to the emergency department stroke units (EDSU). METHODS The neurologists, neuroradiologists and vascular surgeons on duty in emergency departments enrolled 96 patients who underwent very early CEA according to a predefined protocol within two years. The protocol included evaluation of neurological status by National Institute of Health Stroke Scale (NIHSS), neuroimaging assessment, ultrasound of the carotid arteries and Transcranial Doppler. Patients with NIHSS>22 or whose neuroimaging showed brain infarct >2/3 of the middle cerebral artery territory were excluded. All eligible patients underwent CEA as soon as possible. Primary end points of the study were mortality, neurological morbidity by NIHSS and postoperative hemorrhagic conversion on neuroimaging. Statistical analysis was performed by univariate analysis. RESULTS The mean time elapsing between the onset of stroke and endarterectomy was 1.5 days (+/-2 days). The overall 30-day morbidity mortality rate was 7.3% (7/96). No neurological mortality occurred. On hospital discharge, three patients (3%) experienced worsening of the neurological deficit (NIHSS score 1 to 2, 1 to 3 and 9 to 10 respectively). Postoperative CT demonstrated there were no new cerebral infarcts nor hemorrhagic transformation. At hospital discharge 9/96 patients (9%) had no improvement in NHISS scores, 37 were asymptomatic and 45 showed a median decrease of 4.5 NIHSS points (range 1-18). By univariate analysis none of the considered variables influenced the clinical outcome. CONCLUSION Our protocol selected patients who can safely undergo very early (<1.5 days) surgery after acute brain ischemia. Large randomized multicenter prospective trials are warranted to compare very early CEA versus best medical therapy.

Abstract
Ischemic stroke is the most frequent neurological disease, characterized by an age-related incidence and chronic disability in the majority of patients. A great challenge in acute stroke is to predict the degree to which a patient will eventually recover. Magnetic resonance imaging has revealed that treatment-induced reperfusion limits the extent of ischemic brain damage, thereby enabling rapid and profound recovery. Nevertheless, patients may retain deficits in motor, sensory or cognitive functions due to the residual lesion. Functional neuroimaging and transcranial magnetic stimulation have shown that recovery is associated with abnormal activation in the perilesional vicinity and in brain areas remote from the lesion. This is likely related to altered functional properties or morphological changes in both cerebral hemispheres. Recent neurorehabilitative strategies, including forced use, mental imagery and peripheral nerve or cortex stimulation, aim at modulating these functional networks. Accordingly, translational research has provided new vistas on the neurobiological mechanisms of recovery and opened future avenues for science-based pharmacological and neurophysiological training strategies in stroke.

Abstract
BACKGROUND Although it is recognized that carotid endarterectomy (CEA) is the treatment of choice in symptomatic internal carotid artery (ICA) stenosis, in the past, very early CEA has been shown to carry substantial risks. We assessed an interdisciplinary concept of very early CEA in patients with high-grade (>70%) symptomatic ICA stenosis at a single center. PATIENTS AND METHODS The course of treatment and outcomes of patients who underwent CEA as early as possible after being referred to the stroke unit for symptoms of transient ischemic attack and stroke were prospectively evaluated, including the following parameters: age, severity of ischemia-related symptoms according to the modified Rankin scale, duration of symptoms until admission, multimodal imaging findings (color-coded duplex, cranial computed tomography, magnetic resonance imaging, positron emission tomography), duration until CEA, perioperative course and complications, as well as duration of in-hospital care. RESULTS Fifty consecutive patients (median age 68 years, range 44-90) with clinical and imaging signs of transient ischemic attack (n = 19) or stroke (n = 31) were included from January 2000 until December 2004. All except 1 patient showed a preoperative Rankin < 4. There was a median time period of 6 h between the onset of symptoms and admission (range 1 h to 15 days) and a median duration of 4 days after admission until operation (range 1-21 days). Seven patients underwent CEA of the contralateral, severely stenosed ICA after symptomatic ipsilateral ICA occlusion. Four out of 5 patients who primarily underwent systemic thrombolysis recovered almost completely. Three patients (6%) experienced a clinical deterioration before surgery. In the majority of patients (43/50), CEA was performed under local anesthesia with selective shunt use which became necessary in 26%. Three patients (6%) had postoperative worsening due to new infarcts. In 2 cases, an intracerebral hemorrhage occurred, of which 1 remained asymptomatic. In 1 case, surgical revision was necessary because of an ICA thrombosis without permanent neurological decline. Patients were discharged after a median time of 14.5 days (range 4-44). CONCLUSIONS After careful selection and preparation in a stroke unit, patients with acute stroke due to carotid stenosis can undergo very early CEA under local anesthesia with a perioperative risk comparable with the risk of later endarterectomy, therefore preventing very early stroke recurrences.

Abstract
There are very limited data in the literature about the reliability of duplex ultrasound (DU) verified by angiography in patients with restenosis of the internal carotid artery (ICA) after carotid surgery compared with primary carotid artery stenosis patients. Our objective was to compare the reliability of DU verified by conventional angiography in the diagnosis of severe primary stenosis versus restenosis of ICA. One hundred thirty-four patients (238 arteries) were examined by both DU and angiography. Severe stenosis (>70%) was found in 47 primary stenotic arteries and in 70 restenotic arteries. Accuracy, specificity, sensitivity, positive predictive value (PPV), and negative predictive value were obtained for basic DU criteria after verification of ultrasound data by angiography. The best accuracy for detection of >70% stenosis by end diastolic velocity was found for the velocity of 70 cm/sec or more in both groups, but accuracy for the restenosis group was significantly higher (96.9% vs. 89.8%, p = 0.025). Additionally, specificity (p = 0.01) and PPV (p = 0.01) were significantly higher in the restenosis group. The best accuracy for detection of >70% stenosis by peak systolic velocity was found for the velocity of 220 cm/sec or more for restenoses and 200 cm/sec or more for primary stenoses. The accuracy of the ultrasound was significantly higher in the restenosis group (94.6% vs. 87%, p = 0.04), as were specificity (p = 0.01) and PPV (p = 0.02). The diagnosis of severe restenosis by DU is reliable and can be used for decision making regarding surgery or stenting without angiography. In patients with Doppler parameters pointing to borderline moderate/severe primary carotid stenosis and technically complicated cases, angiography in addition to sonography before surgery is recommended.

Abstract
PURPOSE To prospectively determine if the degree of acute perfusion or diffusion abnormalities measured prior to treatment onset help predict the evolution of brain infarction on magnetic resonance (MR) images. MATERIALS AND METHODS Local ethics committee approval and informed consent were obtained. On parametric maps obtained in 64 patients (mean age, 64 years +/- 13 [standard deviation]; 37 men and 27 women) with acute middle cerebral artery infarction, lesion volumetry was performed to determine time to peak, mean transit time, cerebral blood volume, and apparent diffusion coefficient obtained within 3 hours of symptom onset. The infarct lesions were assessed on T2-weighted MR images obtained at follow-up on day 8. Cerebrovascular changes were determined on MR angiograms. Inferential and correlation statistics were used. RESULTS A perfusion delay of more than 6 seconds relative to the nonaffected hemisphere on time-to-peak maps helped to predict the lesion volume on T2-weighted images (r = 0.686, P < .001). In contrast, neither the volume nor the degree of the diffusion abnormality helped to predict the infarct volume (r < 0.46). This was because in one subgroup of patients there was an increase and in one subgroup there was a decrease in infarct volume on the T2-weighted images (P < .001). There was a greater prevalence (P < .02) of cerebral artery abnormalities in the patients with larger infarcts. Clinically, the neurologic impairment was more severe (P < .01) and the mean arterial pressure higher (P < .04) in these patients. CONCLUSION The results suggest that in acute stroke the severity of the initial ischemic event as determined on time-to-peak maps indicates hemodynamic compromise in addition to internal carotid artery or middle cerebral artery occlusion, because of abnormalities in other cerebral arteries.

Abstract
Carotid endarterectomy (CEA) has been used for the past several decades in patients with carotid occlusive disease. Large randomized controlled trials have documented that CEA is a highly effective stroke preventive among patients with carotid stenosis and recent transient ischemic attack or cerebral infarction. In asymptomatic patients with carotid stenosis, clinical trial data suggest that the degree of stroke prevention from CEA is less than among symptomatic patients. However, otherwise healthy men and women with an asymptomatic carotid stenosis of 60% or greater have a lower risk of future cerebral infarction, including disabling cerebral infarction, if treated with CEA compared with those treated with medical management alone. More recently, carotid artery stenting has been performed Increasingly for patients with carotid occlusive disease. As technology has improved, procedural risks have declined and are approaching those reported for CEA. The benefits and durability of CEA compared with carotid artery stenting are still unclear and are being studied in ongoing randomized controlled trials.
