AbstractThere is no consensus for the treatment of a tandem occlusion (TO) in a patient presenting with an acute ischemic stroke. In this review article, we will focus on the controversial treatment strategies for TOs. First, we will discuss treatment options including retrograde, antegrade, and delayed approaches. Second, the role of carotid stent placement versus balloon angioplasty for the extracranial occlusion will be presented. Third, anticoagulation and antiplatelet regimens for the treatment TOs published in the literature will be reviewed. Finally, we will discuss whether there is a role for coil occlusion of the cervical carotid artery or whether staged carotid revascularization days after mechanical thrombectomy of the intracranial occlusion maybe appropriate. The optimal treatment strategy of TO has not been established and further larger trials need to be performed to answer the question.

Tandem Occlusion

Introduction Tandem lesions involving a large vessel occlusion intracranially with concomitant cervical carotid critical stenosis or occlusion are a common presentation of acute ischemic stroke. These lesions are both challenging and time-consuming but can be extremely beneficial for patients when successful. We present a technique utilizing the pusher wire of the stent retriever used for intracranial thrombectomy as the workhorse wire for carotid intervention using a monorail system to perform cervical carotid angioplasty. Methods We reviewed four successive patients who presented with a tandem occlusion and underwent thrombectomy and simultaneous carotid artery intervention using this technique. Results All four patients had radiographically successful intracranial thrombectomy and cervical carotid revascularization. Time from groin puncture to intracranial stent retriever deployment was 63 min on average. Then, using the pusher wire as a monorail workhorse, time from stent retriever deployment to carotid angioplasty was on average 6 min. Discussion This technique allows for cervical carotid revascularization to begin during the recommended 5-min wait time after stent retriever deployment, allowing for rapid near-simultaneous revascularization across both lesions. This technique has been reported briefly in the past for management of a cervical dissection. There is continued debate regarding the management of tandem occlusions, as to which lesion should be managed first. Conclusion As the management paradigms of tandem occlusions continue to evolve, this technique may improve outcomes by expediting endovascular intervention. Using the stent retriever wire provides a method of expediting the management of the proximal lesion after addressing the more distal intracranial occlusion first.

Three recently published trials, MR RESCUE, IMS III, and SYNTHESIS Expansion, evaluating the efficacy and safety of endovascular treatment of acute ischemic stroke have generated concerns about the future of endovascular approach. However, the tremendous evolution that imaging and endovascular treatment modalities have undergone over the past several years has raised doubts about the validity of these trials. In this paper, we review the role of endovascular treatment strategies in acute ischemic stroke and discuss the limitations and shortcomings that prevent generalization of the findings of recent trials. We also provide our experience in endovascular treatment of acute ischemic stroke.

Abstract As ischemic stroke care advances with more patients eligible for mechanical thrombectomy, so too does the role of the neurosurgeon in these patients. Neurosurgeons are an important member of the team from triage through the intensive care unit. This paper explores current research and insights on the contributions of neurosurgeons in care of acute ischemic stroke patients in the acute setting.

Arterial Thrombolysis

Cerebrovascular disease is the second cause of death and the sixth cause of morbidity worldwide, which will rise to fourth place by 2020. The treatment strategies for acute ischemic stroke (AIS) divided into two groups, including intravenous or intra-arterial thrombolysis and mechanical thrombectomy. Regarding growing development in the realm of diagnosis and treatment of stroke through state-of-the-art approaches, including emergent thrombectomy, there are new opportunities for investigation in this area. This is while a rough rate of 85% for strokes is occupied by, and the remained is hemorrhagic. Hence, the present study aimed to review recent advances in AIS with a focus on emergent thrombectomy. Here, we first provided the relevant history, and then the recent advances were discussed. The library data collection method was employed so that such databases as Web of Science, PubMed, and Science Direct used for data extraction. The evidence confirms the importance of emergent thrombectomy as all believe the famous statement "time is the brain." However, further investigations are required to find more strong evidence accordingly.

Механическая тромбэктомия в настоящее время является золотым стандартом в лечении острого ишемического инсульта при окклюзии крупных сосудов передней циркуляции мозгового кровообращения. Однако проблема лечения так называемой тандемной окклюзии - это одновременная окклюзия или критический стенозэкстракраниальной части внутренней сонной артерии (ВСА) в комбинации с окклюзией крупныхвнутримозговых сосудов передней циркуляции мозгового кровообращения в настоящее времяостается актуальной. В данной статье представлен клинический случай успешного лечения тандемной окклюзии внутренней сонной артерии и средней мозговой артерии путем проведения механической тромбэктомии с одномоментным стентированием внутренней сонной артерии. Однако для разработки единого стандарта лечения тандемных окклюзийнеобходимо проведение дальнейших исследований. Mechanical thrombectomy is currently the gold standard in the treatment of acute ischemic stroke with occlusion of large vessels of the anterior circulation of cerebral circulation. However, the problem of treating the so-called tandem occlusion is simultaneous occlusion or extracranial part of the internal carotid artery (ICA) critical stenosis in combination with occlusion of large intracerebral vessels of the anterior cerebral circulation currently remains relevant. This article presents a clinical case of successful treatment of tandem occlusion of the internal carotid artery and middle cerebral artery by mechanical thrombectomy with simultaneous ICA stenting. However, further research is needed to develop a unified standard for the tandem occlusions treatment.

Abstract Background: Mechanical thrombectomy (MT) is an effective treatment for large-vessel occlusion in acute ischemic stroke, however, only some revascularized patients have a good prognosis. For stroke patients undergoing MT, predicting the risk of unfavorable outcomes and adjusting the treatment strategies accordingly can greatly improve prognosis. Therefore, we aimed to develop and validate a nomogram that can predict 3-month unfavorable outcomes for individual stroke patient treated with MT. Methods: We analyzed 238 patients with acute ischemic stroke who underwent MT from January 2018 to October 2020. The primary outcome was a 3-month unfavorable outcome, assessed using the modified Rankin Scale (mRS), 3-6. A nomogram was generated based on a multivariable logistic model. We used the area under the receiver-operating characteristic curve to evaluate the discriminative performance and used the calibration curve and Spiegelhalter’s Z-test to assess the calibration performance of the risk prediction model. Results: After multivariable logistic regression, six variables (gender, bridging therapy, postoperative mTICI, stroke-associated pneumonia, preoperative creatinine and Na) remained independent predictors of 3-month unfavorable outcomes in stroke patients treated with MT, thus forming a nomogram. The area under the nomogram curve was 0.848 with good calibration performance (P = 0.946 for the Spiegelhalter’s Z-test). Conclusions: A novel nomogram consisting of gender, bridging therapy, postoperative mTICI, stroke-associated pneumonia, preoperative creatinine and Na can predict the 3-month unfavorable outcomes in stroke patients treated with MT.

Broad Overview

Neuroimaging has expanded beyond its traditional diagnostic role and become a critical tool in the evaluation and management of stroke. The objectives of imaging include prompt accurate diagnosis, treatment triage, prognosis prediction, and secondary preventative precautions. While capitalizing on the latest treatment options and expanding upon the “time is brain” doctrine, the ultimate goal of imaging is to maximize the number of treated patients and improve the outcome of one the most costly and morbid disease. A broad overview of comprehensive multimodal stroke imaging is presented here to affirm its utilization.
