Abstract
OBJECTIVE To evaluate the safety of carotid artery stenting (CAS) and carotid endarterectomy (CEA) after thrombolytic therapy (TT). DATA SOURCES Medline, Scopus, and Cochrane databases. REVIEW METHODS Systematic review and meta-analysis of studies involving patients who underwent CEA/CAS after TT. RESULTS In 25 studies (n = 147 810 patients), 2 557 underwent CEA (n = 2 076) or CAS (n = 481) following TT. After CEA, the pooled peri-procedural stroke/death rate was 5.2% (95% confidence interval [CI] 3.3 - 7.5) and intracranial haemorrhage (ICH) was 3.4% (95% CI 1.7 - 5.6). After CAS, the pooled peri-procedural stroke/death rate was 14.9% (95% CI 11.9 - 18.2) and ICH was 5.5% (95% CI 3.7 - 7.7). In case control studies comparing CEA outcomes in patients receiving TT vs. no TT, peri-procedural death/stroke was non-significantly higher after TT (4.3% vs. 1.5%; odds ratio [OR] 2.34, 95% CI 0.74 - 7.47), but ICH was significantly higher after TT (2.2% vs. 0.12%; OR 7.82, 95% CI 4.07 - 15.02), as was local haematoma formation (3.6% vs. 2.26%; OR 1.17, 95% CI 1.17 - 2.33). In case control studies comparing CAS outcomes in patients receiving TT vs. no TT, peri-procedural stroke/death was significantly higher after TT (5.2% vs. 1.5%; OR 8.49, 95% CI 2.12 - 33.95) as was ICH (5.4% vs. 0.7%; OR 7.48, 95% CI 4.69 - 11.92). Meta-regression analysis demonstrated an inverse association between the time interval from intravenous (IV) TT to undergoing CEA and the risk of peri-procedural stroke/death (p = .032). Peri-operative stroke/death was 13.0% when CEA was performed three days after TT and 10.6% when performed four days after TT, with the risk reducing to within the currently accepted 6% threshold after six-seven days had elapsed. CONCLUSION Peri-procedural ICH and local haematoma were significantly more frequent in patients undergoing CEA after TT (vs. no TT), although there were no randomised comparisons. Peri-procedural hazards were also significantly higher for CAS after TT. The inverse relationship between timing to CEA and peri-procedural stroke/death mandates careful patient selection and suggests that it may be safer to defer CEA for six-seven days after TT.

Abstract
INTRODUCTION Acute ischemic stroke is a leading cause of morbidity and mortality worldwide, and the incidence of ischemic stroke is predicted to increase in coming years. Carotid atherosclerotic occlusive disease accounts for up to 20% of all ischemic strokes, and mounting evidence suggests that, in the setting of an acute ischemic stroke due to carotid disease, earlier treatment with carotid intervention results in better outcomes. In patients with acute ischemic stroke, systemic or intravenous thrombolysis (IVT) has revolutionized ischemic stroke therapy, and intravenous tissue plasminogen activator (tPA) has become the principal treatment for acute ischemic stroke when administered within 3 to 4.5 hours of neurologic symptom onset. Given these trends in acute ischemic stroke therapy, vascular specialists are increasingly asked to perform carotid intervention following IVT, but reports in the literature examining outcomes in this circumstance are scarce, and the data regarding the appropriate interval from IVT to carotid endarterectomy (CEA) remains controversial. EVIDENCE ACQUISITION Literature searches were performed in PubMed (MEDLINE) and Ovid examining journal articles published between January 1st, 1998 and September 30th, 2019. The search terms used were: "urgent carotid endarterectomy," "carotid endarterectomy" AND "thrombolysis," "acute stroke and thrombolysis," "timing of carotid endarterectomy," and various combinations of these terms. EVIDENCE SYTNHESIS A total of 21 published reports detailing outcomes in 1165 patients have been published to date, with an average interval from IVT to CEA of 7.1 days, a cumulative 30-day stroke and death rate of 4.1% (0-18%) and a mean frequency of intracranial hemorrhage of 2.6% (0-18%). The aggregate data from the 21 reported series suggest that CEA can be performed safely within the first 14 days after the onset of neurologic symptoms in patients receiving antecedent IVT, however, data regarding the safety of urgent CEA within 48 to 72 hours of thrombolysis is conflicting, with some series reporting excellent results and others showing an increased risk of ICH, stroke, and/or death in these select patients. CONCLUSIONS Given the trend toward expedited treatment of acute ischemic stroke with subsequent transfer to regional referral centers, vascular specialists will be confronted with an increasing number of patients who may require urgent CEA after antecedent IVT. Further study is warranted to clearly delineate the appropriate interval from IVT to CEA and, specifically, to establish the safety of CEA with 72 hours of tPA administration.

Abstract
BACKGROUND Thrombolysis is the standard of care for acute ischemic stroke patients presenting in the appropriate time window. Studies suggest that the risk of recurrent ischemia is lower if carotid revascularization is performed early after the index event. The safety of early carotid revascularization in this patient population is unclear. OBJECTIVE To evaluate the safety of carotid revascularization in patients who received thrombolysis for acute ischemic stroke. METHODS The Nationwide Inpatient Sample database was queried for patients admitted through the emergency room with a primary diagnosis of carotid stenosis and/or occlusion. Each patient was reviewed for administration of thrombolysis, carotid endarterectomy, (CEA) or carotid angioplasty and stenting (CAS). Primary endpoints were intracerebral hemorrhage (ICH), postprocedural stroke (PPS), poor outcome, and in-hospital mortality. Potential risk factors were examined using univariate and multivariate analyses. RESULTS A total of 310 257 patients were analyzed. Patients who received tissue plasminogen activator (tPA) and underwent either CEA or CAS had a significantly higher risk of developing an ICH or PPS than patients who underwent either CEA or CAS without tPA administration. The increased risk of ICH or PPS in tPA-treated patients who underwent carotid revascularization diminished with time, and became similar to patients who underwent carotid revascularization without tPA administration by 7 d after thrombolysis. Patients who received tPA and underwent CEA or CAS also had higher odds of poor outcome and in-hospital mortality. CONCLUSION Thrombolysis is a strong risk factor for ICH, PPS, poor outcome, and in-hospital mortality in patients with carotid stenosis/occlusion who undergo carotid revascularization. The increased risk of ICH or PPS due to tPA declines with time after thrombolysis. Delaying carotid revascularization in these patients may therefore be appropriate. This delay, however, will expose these patients to the risk of recurrent stroke. Future studies are needed to determine the relative risks of these 2 adverse events.

Abstract
OBJECTIVE Vascular specialists are increasingly being requested to perform carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) for stroke patients, raising concerns about hemorrhagic complications. Few case series and registry reports have assessed the question, and even fewer studies have included a control group. The aim of this study was to evaluate the overall outcome of patients undergoing CEA after IVT and to compare them with contemporary patients with CEA after simple stroke (non-IVT group). It also aimed to evaluate the differences in outcomes of stroke patients requiring CEA between nonvascular and vascular centers. METHODS The data of 169 consecutive patients who have undergone CEA after stroke in a single center was analyzed from January 2011 to December 2016, 27 of them (16%) having undergone previous IVT. A comparative analysis between the non-IVT and the IVT groups was performed. The time between stroke diagnosis and referral to a vascular specialist was also studied. RESULTS Age, sex, and cardiovascular comorbidities were similar in both groups. Median time between stroke and CEA was 13 days (Q1-Q3, 8-23 days), with 16 of the 27 patients (59%) in the IVT group undergoing CEA less than 14 days after the initial event. There were three intracranial hemorrhages (2.1%) in the non-IVT group versus one (3.7%) in the IVT group (P = NS). The overall 30-day combined stroke and death rate was 7.1% (6.3% in the non-IVT group vs 11.1% in the IVT group; P = .70). The incidence of postoperative cervical hematoma requiring reoperation was similar in both groups (2.1% vs 3.7%; P = NS). The median time between diagnosis of stroke and referral to a vascular specialist was higher for patients in nonvascular centers compared with vascular centers (3.5 days vs 1.0 day; P < .001), which translated to fewer patients referred from nonvascular centers undergoing surgery in the 14-day window period (38% vs 67%; P < .001). CONCLUSIONS In this retrospective analysis, CEA after IVT showed similar outcomes when compared with the overall CEA after stroke population. Stroke patients diagnosed in nonvascular centers were referred later than those in vascular centers and, although postoperative outcomes were similar, that was correlated with fewer patients undergoing surgery in a timely fashion.

Abstract
Acute occlusion of the extracranial internal carotid artery (eICA) is associated with poor prognosis. Surgical desobliteration has not received adequate attention in recent years. We therefore conducted a literature review and meta-analysis of surgical studies published after 2000 that treated eICA occlusion surgically in an emergency setting. The search identified 10 relevant articles that included a total of 175 patients. The outcomes analysed included rates of recanalization (93 %), early neurological improvement (66 %), modified Rankin Scale 0-2 (62 %), mortality (5 %), early reocclusion (4 %), in-hospital stroke (4 %) and symptomatic intracerebral haemorrhage (4 %). In conclusion, acute surgical desobliteration of eICA occlusion leads to high rates of recanalization and a majority of patients experience early neurological improvement and achieve favourable outcome. Rates of mortality, early reocclusion, in-hospital stroke and sICH are acceptable in the view of unfavourable natural history.

Abstract
BACKGROUND Intravenous recombinant tissue-type plasminogen activator (rt-PA) with/without endovascular treatment is not as effective in atherosclerotic steno-occlusive acute ischemic stroke. Urgent superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is effective to some extent in progressing stroke, but the safety of STA-MCA anastomosis soon after rt-PA therapy is unknown. Our aim was to clarify the safety of STA-MCA anastomosis within 24 h after intravenous rt-PA. METHOD From 2005 to 2015, rt-PA was administered to 225 patients presenting with acute ischemic stroke according to the Japanese Stroke Guidelines, in our institution. Five patients underwent urgent STA-MCA anastomosis after rt-PA administration with or without endovascular recanalization. Clinical time course, surgical complications, and patients' prognosis were investigated. RESULTS The average of patient age was 65.4 years (range 49-77 years); three patients had internal carotid artery occlusion, and two patients had middle cerebral artery occlusion. The median National Institutes of Health Stroke Scale score on admission was 12.4 (range 6-17 points) and operation occurred 10.6 h (range 5.3-23.6 h) after intravenous rt-PA administration. Hemostasis was achieved during standard STA-MCA anastomosis, and there were no hemorrhagic complications. CONCLUSIONS In our consecutive cases, urgent STA-MCA anastomosis after at least 5.3 h after intravenous rt-PA was performed safely without hemorrhagic complications.

Abstract
Tandem internal carotid artery (ICA) origin occlusion and middle cerebral artery (MCA) thromboembolism is a life-threatening condition with poor neurological outcome. The authors report on a patient presenting with acute ischemic stroke from a tandem ICA and MCA occlusion with penumbra. Emergency MCA mechanical thrombectomy was performed through percutaneous cervical ICA access due to the inability to cross the cervical carotid occlusion. Emergency carotid endarterectomy to reperfuse the poorly collateralized hemisphere and repair the ICA access site was performed 2 hours after completion of tissue plasminogen activator (tPA) infusion. This case illustrates the shortest reported interval between tPA infusion and open surgical intervention for carotid revascularization, as well as the role of direct carotid artery access for mechanical thrombectomy. The authors also describe the use of a temporizing femoral artery-to-ICA shunt to maintain cerebral perfusion in the setting of ICA occlusion.

Abstract
BACKGROUND The timing of carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) is still a controversial issue. The aim of this study was to assess the safety of early carotid interventions in patients treated with thrombolysis for acute ischemic stroke. METHODS A retrospective analysis was performed using prospectively collected data from consecutive patients who underwent CEA for symptomatic internal carotid artery stenosis within 14 days after the index neurological event during the period from January 2013 to July 2016. Patients who had undergone IVT before CEA were identified. The primary outcome measures were any stroke and death rate at 30 days, symptomatic intracerebral hemorrhage and surgical site bleeding requiring intervention. RESULTS A total of 93 patients were included for the final analysis. Among these, 13 (14.0%) patients had undergone IVT before CEA while 80 (86.0%) patients had CEA only. The median time interval between IVT and CEA was 2 days (range: 0-13). A subgroup of 6 patients underwent CEA within 24 hours of administration of IVT. The 30-day combined stroke and death rate was 7.7% (1 of 13) among patients undergoing IVT before CEA and 5.0% (4 of 80) among those undergoing CEA only (P = 0.690). In the IVT group, there were no cerebral hemorrhages or significant surgical site bleeding events requiring reintervention. CONCLUSIONS Our experience indicates that CEA performed early after IVT for acute ischemic stroke, aiming not only to reduce the risk of stroke recurrence but also to achieve neurological improvement by reperfusion of the ischemic penumbra, may be safe and can lead to favorable outcomes.

Abstract
Although intravenous recombinant tissue plasminogen activator (IV rt-PA) is effective in many cases of acute ischemic stroke, the neurologic symptoms can worsen after IV rt-PA because of sustained vessel occlusion. For such cases, several reperfusion modalities are available, including intra-arterial thrombolysis (IAT), carotid endarterectomy, and superficial temporal artery-middle cerebral artery (STA-MCA) bypass. Invasive procedures, such as major surgery, should be generally avoided within 24 hours after the administration of IV rt-PA. A 66-year-old man with no previous medical history developed left hemiparesis. A computed tomography scan revealed no acute lesion and he received IV rt-PA within 1.5 hours after symptom onset. Emergent magnetic resonance imaging showed significant diffusion-perfusion mismatch. He received IAT 2 hours after IV rt-PA administration, but IAT failed because of total occlusion of the cervical internal carotid artery. We initially planned to perform STA-MCA bypass the next morning because he had received IV rt-PA, but, 8 hours after IV rt-PA administration, his hemiparesis worsened from motor grade 3/4 to motor grade 1/2. Because of the large perfusion defect in both MCA divisions, double-barrel STA-MCA bypass was performed 10 hours after IV rt-PA administration. His symptoms rapidly improved after surgery and his modified Rankin Scale score 3 months later was grade 0. We suggest that emergent double-barrel bypass can be a viable option in patients who have perfusion defects of both MCA divisions in acute ischemic stroke after IV rt-PA administration.

Abstract
OBJECTIVE/BACKGROUND The timing of carotid endarterectomy (CEA) after thrombolysis is still a matter of debate. The aim of this study was to analyse a cohort of patients undergoing urgent endarterectomy after intravenous thrombolysis for acute ischaemic stroke. METHODS This was an observational study. Prospective databases were reviewed and matched to identify patients who underwent CEA early after intravenous thrombolysis (2009-14). The focus was carotid surgery performed within 12 hours of stroke onset in patients with a high grade (≥70%) symptomatic carotid stenosis, associated with vulnerable plaques or stroke in evolution, and evidence of a significant salvageable ischaemic penumbra on perfusion computed tomography scan. Demographic and clinical information, as well as data on relevant outcomes were extracted. RESULTS Thirty four consecutive stroke patients who underwent CEA within 2 weeks of thrombolysis for acute ischaemic stroke and ipsilateral high grade carotid stenosis were identified. In 11 patients the surgical procedure was performed within 12 hours of the onset of symptoms. All patients showed a clinical improvement after combined treatment. The 3 month outcome was favourable (modified Rankin Scale ≤ 2) in 10 patients. No haemorrhagic complications were registered. There was neither peri-operative stroke nor stroke within 3 months of surgery. One patient died from acute myocardial infarction 3 days after intervention. CONCLUSION This experience suggests that very early CEA after thrombolysis, aimed at removing the source of potential embolisation and restoring blood flow, may be safe and can lead to a favourable outcome.

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
BACKGROUND Carotid endarterectomy (CEA) for symptomatic carotid artery stenosis and intravenous tissue-type plasminogen activator (IV-tPA) for acute ischemic stroke are proven therapies; however, the safety of CEA in stroke patients who recently received IV-tPA has not been established. OBJECTIVE To evaluate the safety of CEA in stroke patients who recently received IV-tPA. METHODS A retrospective review of patients who underwent CEA for symptomatic carotid artery stenosis was performed. The primary end point was postoperative symptomatic intracerebral hemorrhage (sICH). A univariate analysis of potential risk factors for sICH, including IV-tPA therapy, timing of CEA, degree of stenosis, and stroke severity, was performed. Factors with a value of P < .1 on univariate analysis were tested further. RESULTS Among 142 patients, 3 suffered sICH after CEA: 2 of 11 patients treated with IV-tPA (18.2%) and 1 of 131 patients not treated with IV-tPA (0.8%). Both IV-tPA patients suffering sICH underwent CEA within 3 days of tPA administration. On univariate analysis, IV-tPA (P = .02), female sex (P = .09), shorter time between ischemic event and CEA (P = .06), and lower mean arterial pressure during the first 48 hours of admission (P = .08) were identified as risk factors for sICH. On multivariate analysis, IV-tPA was the only significant risk factor (P = .002 by stepwise logistic regression; P = .03 by nominal logistic regression). CONCLUSION This study indicates that IV-tPA is an independent risk factor for sICH after CEA. This suggests that CEA should be pursued cautiously in patients who recently received IV-tPA. Early surgery may be associated with an increased risk for sICH.

Abstract
Whether to provide surgical intervention within 24 hours of intravenous recombinant tissue plasminogen activator (rt-PA) treatment is a subject of controversy. In this study, we report a case in which neurological deterioration was prevented by urgent bypass surgery performed shortly after rt-PA treatment.

Abstract
Background. Patients with acute ischemic stroke due to internal carotid artery (ICA) disease are at high risk of early stroke recurrence. A combination of IV thrombolysis and early carotid artery stenting (CAS) may result in more effective secondary stroke prevention. Objective. We tested safety and durability of early CAS following IV thrombolysis in stroke patients with residual stenosis in the symptomatic ICA. Methods. Of consecutive patients treated with IV rtPA, those with residual ICA stenosis ≥70% or <70% with an ulcerated plaque underwent early CAS (>24 hours). The protocol included pre-rtPA MRI and MR angiography, and post-rtPA carotid ultrasound and CT angiography. Stroke severity was assessed by the NIH Stroke Scale (NIHSS). Three- and twelve-month stent patency was assessed by ultrasound. Twelve-month functional outcome was assessed by the modified Rankin Scale (mRS). Results. Of 145 consecutive IV rtPA-treated patients, 6 (4%) underwent early CAS. Median age was 76 (range 67-78) years, median NIHSS at stroke onset was 12 (range 9-16) and 7 (range 7-8) before CAS. Median onset-to-CAS time was 48 (range 30-94) hours. A single self-expandable stent was implanted to cover the entire lesion in all patients. The procedure was uneventful in all patients. After 12 months, all patients had stent patency, and the functional outcome was favourable (mRS ≤ 2) in all but 1 patient experiencing a recurrent stroke for new-onset atrial fibrillation. Conclusion. This small case series of a single centre suggests that early CAS may be considered a safe alternative to CEA after IV rtPA administration in selected patients at high risk of stroke recurrence.

Abstract
Abstract
Background
Thrombolysis with intravenous recombinant tissue plasminogen activator improves the probability of complete neurological recovery if given promptly following the onset of acute ischaemic stroke. Carotid endarterectomy (CEA) can reduce the risk of further embolic stroke in selected patients and is most effective within 14 days of the incident event. The safety of surgery so soon after thrombolysis is unknown. The aim of this study was to report the immediate outcomes of this management strategy early in the unit experience and to encourage pooling of data, recognizing that this will be an uncommon procedure even in busy stoke units with an active lysis programme.
Methods
Data were extracted from two prospectively collected databases, and included patient demographics, type of stroke, type and timing of surgical procedure, and immediate outcome. On presentation with a stroke, all patients underwent urgent computed tomography (CT) of the brain. Those eligible received thrombolysis according to the unit protocol. They underwent CT angiography 24 h after thrombolysis and patients with a severe carotid stenosis had surgery.
Results
Ten of a cohort of 450 patients who had received lysis underwent CEA. Seven of these were women and eight of the procedures were carried out under local anaesthetic. Surgery was performed a median of 8 (range 2–23) days after the index event; there were no major complications.
Conclusion
Few patients with acute stroke are eligible, but CEA performed soon after thrombolytic therapy for stroke appears to be safe.

Abstract
We report the case of a 55-year-old man who presented with a left hemisphere stroke. The initial computed tomography scan demonstrated a cerebral infarct in association with a left middle cerebral artery occlusion. Carotid duplex ultrasound imaging revealed a surgical grade stenosis of the proximal left internal carotid artery; however, in view of the uncertain benefits of internal carotid endarterectomy in the face of ipsilateral middle cerebral artery occlusion, surgery was deferred. Subsequent surveillance by transcranial Doppler imaging and repeat computed tomography demonstrated spontaneous recanalization. The patient proceeded to carotid endarterectomy with no complications.
