J Neurointerv Surg 2020; 13:141-145. [PMID: 32532859 DOI: 10.1136/neurintsurg-2020-015817] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 05/08/2020] [Accepted: 05/12/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND The benefit of acute carotid stenting compared with no acute stenting on clinical outcomes among patients with tandem lesions (TL) undergoing endovascular thrombectomy (EVT) remains unknown. METHODS We conducted a a systematic review and meta-analysis of studies comparing acute carotid stenting versus no stenting among TL patients undergoing EVT with regards to 90 day modified Rankin Scale (mRS) score, symptomatic intracerebral hemorrhage (sICH), and mortality. Four reviewers screened citations for eligibility and two assessed retained studies for risk of bias and data extraction. A random effects model was used for the synthesis of aggregated data. RESULTS 21 studies (n=1635 patients) were identified for the systematic review; 19 were cohort studies, 1 was a post-hoc analysis of an EVT trial, and 1 was a pilot randomized controlled trial. 16 studies were included in the meta-analysis. Acute stenting was associated with a favorable 90 day mRS score: OR 1.43 (95% CI 1.07, 1.91). No significant heterogeneity between studies was found for this outcome (I2=17.0%; χ2=18.07, p=0.26). There were no statistically significant differences for 3 month mortality (OR 0.80 (95% CI 0.50, 1.28)) or sICH (OR 1.41 (95% CI 0.91, 2.19)). CONCLUSIONS This meta-analysis suggests that among TL patients undergoing EVT, acute carotid stenting is associated with a greater likelihood of favorable outcome at 90 days compared with no stenting.

Limb shaking transient ischemic attacks: A follow-up of 28 patients. Rev Neurol (Paris) 2020; 176:587-591. [PMID: 31916976 DOI: 10.1016/j.neurol.2019.12.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 11/12/2019] [Accepted: 12/17/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND Limb shaking transient ischemic attack (LSTIA) is an uncommon picture of carotid-occlusive disease. The symptoms are a seizure like activity and misdiagnosed as partial motor seizures. We here present a series of patients in our registry who had limb-shaking activities and their long-term outcome after treatment of their disease. METHODS A total of 28 patients with limb shaking symptoms were recruited among 798 patients with TIA in our stroke registry. Risk factors and etiology of LSTIA were examined within hospitalization. After the initiaition of treatment patients were followed for a median of 6months. RESULTS Limb-shaking was observed mainly on the hand-arms (46%), and secondly on the legs (39%). We found five different DWI lesion patterns in patients with LSTIA, including unilateral or bilateral either cortical or borderzone ischemic hyperintensities. Carotid endarterectomy was performed in 9 (32%) patients and carotid angioplasty-stent (CAS) in 10 (36%), and after 6-months of follow-up none of the patients had LSTIA. Limb shaking continued only in a patient with chronic carotid occlusion who received only conservative treatment. CONCLUSIONS Limb shaking TIA point to carotid artery disease in the majority of patients and vertebrobasilar artery disease in one third. Fast and timely treatment with either surgical or CAS eliminates the attacks and also reduce their risk of stroke.

Abstract
This study aimed to evaluate the efficacy and safety of endovascular repair using detachable Solitaire AB stents for acute ischemic dissection of "S"-shaped carotid arteries. From May 2015 to December 2016, a total of 127 patients with acute ischemic stroke (AIS) underwent endovascular treatment in our center. Among them, five AISs were due to acute dissection of an "S"-shaped carotid artery. Coexisting carotid embolism was identified in all five patients, who first underwent successful Solitaire AB stent-based retrieval of the embolism. All patients then underwent Solitaire AB stenting to reopen the occluded carotid arteries, all of which were successfully recanalized. There were no procedure-related complications, except for minor hemorrhage transformation in one patient. The mean NIHSS scores were 12 ± 3.7 and 3.8 ± 3.4 at admission and 90 days after stenting, respectively (P = 0.018). The median modified Rankin Scale score at 90 days was 2.0 ± 1.4. Follow-up computed tomography angiography demonstrated in-stent patency in four of the five patients. Dissection of an "S"-shaped carotid artery infrequently leads to AIS. Such dissected arteries can be safely and reliably repaired by this stenting, ensuring successful reconstruction of the carotid arterial circulation.

Abstract
OBJECTIVES Acute cervical carotid occlusion is one of the most challenging scenarios encountered in endovascular stroke treatment. PATIENTS AND METHODS A retrospective analysis of 11 consecutive non-dissection stroke patients with concomitant cervical carotid and intracranial occlusion treated with intraarterial (IA) mechanical thrombectomy and/or pharmacologic thrombolysis over five years at two academic hospitals was performed. Data was analyzed using Fisher's exact test. RESULTS Patients included 3 females and 8 males. Average age was 64.7 years (range 30-94 years). All patients had both cervical carotid and intracranial occlusions. Intracranial occlusion involved the internal carotid artery in 7 patients and the middle cerebral artery in 4 patients. All of the patients received intracranial IA Tissue Plasminogen Activator (tPA). Six patients received carotid stents for cervical occlusion as part of their treatment. Five patients received only IA tPA via collateral circulation. Of the patients receiving stents, 5 of 6 (83.3%) had successful recanalization (Thrombolysis in Cerebral Ischemia 2b or 3 flow). Only 1 of 5 (20%) patients who did not receive stents prior to intracranial treatment had successful recanalization. The difference in recanalization rates approached statistical significance (p=.08). There were 4 total in-hospital mortalities: 2 in the group that received stents prior to thrombolysis and 2 in the non-stent group. There were 2 clinically significant hemorrhages in the study, both in the stent group. CONCLUSIONS Revascularization of the cervical carotid occlusion prior to treatment of the intracranial occlusion led to increased rates of recanalization in patients with tandem extracranial and intracranial occlusions. Whether a clinical benefit can be consistently derived likely relies on other factors, including the evaluation of cerebral perfusion.

Abstract
OBJECT Approximately 25% of patients with middle cerebral artery (MCA) occlusion will have a concomitant internal carotid artery (ICA) occlusion, and 50% of patients with an ICA occlusion will have a proximal MCA occlusion. Cervical ICA occlusion with MCA embolic occlusion is associated with a low rate of recanalization and poor outcome after intravenous thrombolysis. The authors report their experience with acute ischemic stroke patients who suffered tandem ICA/MCA (TIM) occlusions and underwent intravenous thrombolysis followed by extracranial ICA angioplasty and intracranial MCA mechanical thrombectomy. METHODS In a retrospective analysis of their stroke database (2008-2011), the authors identified 2 patients with TIM occlusion treated with intravenous thrombolysis followed by extracranial ICA angioplasty and intracranial mechanical thrombectomy. They examined early neurological improvement defined by a greater than 10-point reduction of National Institutes of Health Stroke Scale (NIHSS) score and an improved modified Rankin Scale (mRS) score at 60 days. Successful recanalization based on thrombolysis in cerebral infarction (TICI) score of 2 or 3 was also evaluated. RESULTS In both patients a TICI score of 2b or 3 was achieved, signifying successful recanalization. In addition, both patients had a reduction in the NIHSS score by greater than 10 points and an mRS score of 0 at 60 days. CONCLUSIONS Tandem occlusions of the cervical ICA and MCA may be successfully treated using the multimodality approach of intravenous thrombolysis followed by extracranial ICA angioplasty and intracranial mechanical thrombectomy.

Abstract
A comprehensive endovascular skill set is desirable and key to successful intervention in the patient with complex cardiovascular disease. Acute stroke intervention is the next frontier for the endovascular specialist. We report a case of acute stroke intervention in a patient with severe peripheral vascular disease performed by interventional cardiologists with peripheral endovascular skills that clearly demonstrates the new paradigm of global revascularization.

Abstract
Carotid stenosis is a major risk factor for stroke. With the aging of the general population and the availability of non-invasive vascular imaging studies, the diagnosis of a carotid plaque is commonly made in medical practice. Asymptomatic and symptomatic carotid stenoses need to be considered separately because their natural history is different. Two large randomized controlled trials (RCTs) showed the effectiveness of carotid endarterectomy (CEA) in preventing ipsilateral ischemic events in patients with symptomatic severe stenosis. The benefit of surgery is much less for moderate stenosis and harmful in patients with stenosis less than 50%. Surgery has a marginal benefit in patients with asymptomatic stenosis. Improvements in medical treatment must be taken into consideration when interpreting the results of these previous trials which compared surgery against medical treatment available at the time the trials were conducted. Carotid artery stenting (CAS) might avoid the risks associated with surgery, including cranial nerve palsy, myocardial infarction, or pulmonary embolism. Therefore and additionally to well-established indications of CAS, this endovascular approach might be a valid alternative particularly in patients at high surgical risk. However, trials of endovascular treatment of carotid stenosis have failed to provide enough evidence to justify routine CAS as an alternative to CEA in patients suitable for surgery. More data from ongoing randomized trials of CEA versus CAS will be soon available. These results will help determining the role of CAS in the management of patients with carotid artery stenosis.

Abstract
INTRODUCTION Internal carotid artery dissection with tandem internal carotid and middle cerebral artery occlusion may be responsible for large cerebral infarction that carries a general poor prognosis. Recanalization of internal carotid artery (ICA) dissection by stent-assisted thrombolysis has been recently proposed. We report two cases of acute symptomatic ICA dissection with tandem occlusion successfully treated with emergent endovascular stent-assisted thrombolysis using new self-expandable intracranial stents. METHODS A 37-year-old woman and a 59-year-old man were admitted in our hospital after acute severe symptoms of right-hemispheric stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 15 and 18, respectively. In both cases, magnetic resonance angiography showed tandem occlusion and angiography confirmed tandem occlusion with ICA dissection. An extensive mismatch region was diagnosed by Perfusion-diffusion MRI of the brain within 3 h after symptoms onset. Treatment was initiated 4 h after symptom onset by implantation of self-expandable intracranial stents into the dissected ICA and administration of intra-arterial recombinant tissue plasminogen activator. RESULTS Recanalization of the ICA and middle cerebral artery (MCA) was accomplished within 6 h after symptoms onset. In both cases, no periprocedural complication was observed and follow-up CT scan showed only a mild brain infarct in the MCA territory. After, respectively, 12 and 10 months follow-up, patients had a favorable outcome with NIHSS 0 and mRS < or = 1. CONCLUSION Endovascular stent-assisted thrombolysis appears to be a promising treatment in tandem occlusion due to ICA dissection. Our work underline the potential use of self-expandable intracranial stents in symptomatic acute ICA dissection.

Abstract
Acute symptomatic occlusion of the cervical internal carotid artery (ICA) can be treated by intravenous administration of tissue plasminogen activator, percutaneous transluminal angioplasty, and carotid endarterectomy. Carotid artery stenting (CAS) is now indicated for cervical ICA stenosis, but the safety and the efficacy of urgent CAS have not been established. We retrospectively reviewed 10 patients treated by urgent CAS for atherosclerotic occlusive lesions of cervical ICA with acute stroke. Five patients had complete occlusions and five had near total occlusions. Five of the 10 patients had intracranial tandem occlusions. Indication for urgent CAS was determined by mismatch of diffusion-weighted and perfusion-weighted magnetic resonance imaging findings. Stents were successfully deployed in all lesions. Three of five patients with concomitant intracranial tandem occlusions were treated by additional intraarterial fibrinolysis after the CAS. Intracranial artery occlusions were completely recanalized in one patient, and partially recanalized in two by fibrinolysis. Hyperperfusion syndrome did not occur in any of the patients. A favorable outcome (modified Rankin Scale < or =1) was obtained in all of the five patients with isolated cervical ICA occlusion and one of the five patients with intracranial tandem occlusions. Urgent CAS is a safe and effective treatment in patients with isolated cervical ICA occlusion. Treatment of intracranial tandem occlusions is an issue that must be resolved.

Abstract
BACKGROUND AND PURPOSE The timely re-establishment of intracranial perfusion, the effective prevention of early recurrent strokes, and the limitation of the incidence of reperfusion injury are the major factors that are key to successful treatment of patients with hyperacute stroke who had severe ipsilateral cervical internal carotid artery (ICA) stenosis. In an effort to reduce both the extent of the ongoing neurologic injury and the risk of early recurrent stroke, we have adopted an aggressive combined endovascular approach of intracranial thrombolysis and cervical carotid stent placement during the hyperacute phase. We report on the results of 5 such consecutive patients who presented to our center from January 2003 through January 2005. MATERIALS AND METHODS From January 2003 through January 2005, 5 consecutive patients presented to our center with hyperacute strokes and severe ipsilateral cervical ICA stenosis. All were treated with emergent carotid stent placement and intra-arterial thrombolysis. The medical records were reviewed and summarized. RESULTS One patient died. The remaining 4 patients had an average hospital stay of 4 days (range, 3-5 days) and a mean National Institutes of Health Stroke Scale (NIHSS) score of 2 (range, 0-3) at the time of discharge. With a mean clinical follow-up of 11 months (range, 6-24 months), all had excellent functional outcome with a modified Rankin score of 0 or 1. CONCLUSIONS Data on emergent carotid stent placement in the hyperacute management of stroke are limited. The summarized experience in these 5 patients demonstrates the feasibility of this aggressive therapeutic strategy that may bring about a good outcome.

Abstract
INTRODUCTION Carotid angioplasty with stenting (CAS) is becoming accepted as an effective and reliable treatment option for severe carotid artery stenosis. However, it is rarely applied for carotid occlusion, especially in its chronic stage. We report our experience of CAS for chronic internal carotid artery occlusion representing compromised cerebral blood flow using various protection methods. METHODS A 77-year-old woman, who was already diagnosed with severe left internal carotid artery stenosis, suddenly had right hemiparesis and aphasia. At that time, she was treated conservatively because her neurological status was quite good, in spite of left carotid artery occlusion. Her symptoms improved in the short term, except slight aphasia, but deteriorated again 18 days from the onset, and magnetic resonance imaging (MRI) showed new ischemic lesions. CAS was then performed for the occluded carotid artery on the 23rd day from the first onset. RESULTS Using the proximal protection technique, the occluded lesion was crossed carefully with a microguidewire. Stents were also placed successfully with the distal protection technique. The occluded carotid artery was completely recanalized without any unfavorable events or neurological deterioration. CONCLUSION In this patient, CAS was successfully to treat chronic carotid artery occlusion. These procedures and techniques are reviewed and discussed.

Abstract
BACKGROUND A CTO of the intracranial ICA is usually managed medically and rarely by EC-IC bypass in selected patients. Percutaneous transluminal angioplasty has not been used. CASE DESCRIPTION A 73-year-old man presented with frequent temporary blindness of the left eye and dizziness due to thrombotic occlusion of the left intracranial ICA, causing hemodynamic compromise. This patient was successfully treated by percutaneous angioplasty (balloon angioplasty and stent placement) under proximal balloon protection at 7 weeks from the ictus. Ischemic symptoms had not recurred during the 6-month follow-up period. CONCLUSION Percutaneous angioplasty for a CTO of the intracranial ICA is technically feasible and can be an alternative to EC-IC bypass in a selected group of patients with symptomatic hemodynamic compromise, which is refractory to the best medical treatment.

Background Limb shaking Transient Ischemic Attack is a rare manifestation of carotid-occlusive disease. The symptoms usually point towards a seizure like activity and misdiagnosed as focal seizures. On careful history the rhythmic seizure like activity reveals no Jacksonian march mainly precipitated by maneuvers which lead to carotid compression. We here present a case of an elderly gentleman who was initially worked up as suffering from epileptic discharge and then later on found to have carotid occlusion. Case presentation Elderly gentleman presented with symptoms of rhythmic jerky movements of the left arm and both the lower limbs. Clinical suspicion of focal epilepsy was made and EEG, MRI-Brain with MRA were done. EEG and MRI-Brain revealed normal findings but the MRA revealed complete occlusion of right internal carotid artery. On a follow-up visit jerky movements of the left arm were precipitated by hyperextension and a tremor of 3–4 Hz was revealed. Based on this the diagnosis of low flow TIA was made the patient was treated conservatively with adjustment of his anti-hypertensive and anti-platelet medications. Conclusion Diagnosis of limb-shaking TIA is important and should be differentiated from other disorders presenting as tremors. Timely diagnosis is important as these patients are shown to benefit from reperfusion procedures either surgical or radiological reducing their risk of stroke.

Abstract
SUMMARY Emergency revascularization of acute carotid artery occlusion is still controversial.We treated 15 patients (13 men and two women, mean age of 67.3 years) with acute atherosclerotic carotid occlusion by endovascular procedures and evaluated the usefulness of this treatment. All of the patients were evaluated with emergency MRI and MRA before treatment. Intracranial tandem arterial occlusion due to distal embolism was observed in nine patients, and contralateral carotid stenosis (> 70%) was observed in seven. The mean NIHSS score of the patients was 15.4 +/- 7.4 (mean +/- SD) before treatment. Treatment modality included local intraarterial fibrinolysis (LIF), percutaneous transluminal angioplasty (PTA), and carotid artery stenting (CAS). A protective balloon was successfully placed in the distal carotid artery through the plaque before recanalization in seven patients. Three patients were treated with LIF+PTA, five with PTA+CAS, six with LIF+PTA+CAS, and one with PTA only. Successful recanalization of the carotid artery was obtained in 14 of the 15 patients, and distal tandem middle cerebral artery occlusion was also successfully recanalized in eight of the nine patients. GOS was four or five in eight patients (good outcome group) and 1-3 in seven patients (poor outcome group). Mean NIHSS score of the 15 patients was (6.9 +/- 7.4) after treatment. Preoperative NIHSS score (10.3 +/- 7.4) in the good outcome group was significantly lower than that (21.3 +/- 5.4) in the poor outcome group. The protective balloon technique, PTA with stenting, seems to be useful for acute revascularization of urgent carotid occlusion. Simultaneous treatment of the intracranial tandem occlusive lesion is essential to achieve good clini-cal results. Patients with acute carotid occlusion with NIHSS scores of less than 16 could be good candidates for this advanced treatment.

Abstract
PURPOSE To evaluate retrospectively the outcome for patients with acute ischemic stroke in the territory of the middle cerebral artery (MCA) who had undergone stent implantation in the proximal segment of the internal carotid artery (ICA) in addition to intraarterial thrombolysis (IAT). MATERIALS AND METHODS Stent implantation and retrospective analysis of clinical and radiologic data were approved by the institutional ethical committee. Endovascular treatment was performed after obtaining informed consent from patients or their closest relatives. Informed consent for retrospective review was not required. After pharmacologic and/or mechanical IAT, 25 consecutive patients (seven women, 18 men; mean age, 59 years +/- 14 [standard deviation]) underwent stent implantation in the proximal segment of the ICA (endovascular group). The clinical and radiologic characteristics (ie, interval from symptom onset to arrival at the emergency department, prevalence of vascular risk factors, causes of stroke, stroke severity, early signs of cerebral ischemia, duration of endovascular intervention, type of occlusion, and prevalence of leptomeningeal collateral vessels), recanalization rates, and clinical outcomes for patients in the endovascular group were compared with those for patients in the medical group (10 women, 21 men; mean age, 62 years +/- 12) who experienced ischemic stroke in the territory of the MCA as a result of ICA occlusion and who received antithrombotic treatment only. Differences between groups were assessed by using the chi2 test. A logistic regression analysis was performed to assess the effect of clinical and radiologic factors on recanalization rates and outcome. RESULTS ICA recanalization was successful in 21 patients. Good recanalization of the MCA was achieved in 11 patients. In nine of these patients, recanalization of the MCA was achieved by using mechanical IAT only. In the remaining 12 patients, administration of intraarterial urokinase was performed in addition to mechanical thrombolysis. Two patients from the endovascular group experienced symptomatic intracerebral hemorrhage. At 3 months, 56% of the endovascular group and 26% of the medical group had a favorable outcome. Mortality was 20% in the endovascular and 16% in the medical group. CONCLUSION IAT and stent implantation in the proximal segment of the ICA seem to improve the outcome for patients with ischemic stroke caused by occlusion of the cervical portion of the ICA.

Abstract
Patients with complete carotid occlusion and recent ischemic symptoms are at high risk for subsequent stroke, particularly those with evidence of severe hemodynamic impairment due to poor collateral flow. Treatment options for these patients include direct extracranial to intracranial arterial bypass, or interventions aimed at improving collateral sources of flow such as endarterectomy or angioplasty and stenting of the ipsilateral external carotid artery, the contralateral carotid artery, or the vertebral arteries. The evidence supporting the use of these procedures for patients with complete occlusion of the carotid artery will be the focus of this article. The use of physiologic imaging to select subgroups of patients at high risk due to hemodynamic factors will also be discussed.
