Imaging Characteristics

Background and Purpose— Thrombus imaging characteristics have been reported to be useful to predict functional outcome and reperfusion in acute ischemic stroke. However, conflicting data about this subject exist in patients undergoing endovascular treatment. Therefore, we aimed to evaluate whether thrombus imaging characteristics assessed on computed tomography are associated with outcomes in patients with acute ischemic stroke treated by endovascular treatment. Methods— The MR CLEAN (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands) Registry is an ongoing, prospective, and observational study in all centers performing endovascular treatment in the Netherlands. We evaluated associations of thrombus imaging characteristics with the functional outcome (modified Rankin Scale at 90 days), mortality, reperfusion, duration of endovascular treatment, and symptomatic intracranial hemorrhage using univariable and multivariable regression models. Thrombus characteristics included location, clot burden score (CBS), length, relative and absolute attenuation, perviousness, and distance from the internal carotid artery terminus to the thrombus. All characteristics were assessed on thin-slice (≤2.5 mm) noncontrast computed tomography and computed tomography angiography, acquired within 30 minutes from each other. Results— In total, 408 patients were analyzed. Thrombus with distal location, higher CBS, and shorter length were associated with better functional outcome (adjusted common odds ratio, 3.3; 95% CI, 2.0–5.3 for distal M1 occlusion compared with internal carotid artery occlusion; adjusted common odds ratio, 1.15; 95% CI, 1.07–1.24 per CBS point; and adjusted common odds ratio, 0.96; 95% CI, 0.94–0.99 per mm, respectively) and reduced duration of endovascular procedure (adjusted coefficient B, −14.7; 95% CI, −24.2 to −5.1 for distal M1 occlusion compared with internal carotid artery occlusion; adjusted coefficient B, −8.5; 95% CI, −14.5 to −2.4 per CBS point; and adjusted coefficient B, 7.3; 95% CI, 2.9–11.8 per mm, respectively). Thrombus perviousness was associated with better functional outcome (adjusted common odds ratio, 1.01; 95% CI, 1.00–1.02 per Hounsfield units increase). Distal thrombi were associated with successful reperfusion (adjusted odds ratio, 2.6; 95% CI, 1.4–4.9 for proximal M1 occlusion compared with internal carotid artery occlusion). Conclusions— Distal location, higher CBS, and shorter length are associated with better functional outcome and faster endovascular procedure. Distal thrombus is strongly associated with successful reperfusion, and a pervious thrombus is associated with better functional outcome.

Background and Purpose— Collateral circulation status at baseline is associated with functional outcome after ischemic stroke and effect of endovascular treatment. We aimed to identify clinical and imaging determinants that are associated with collateral grade on baseline computed tomography angiography in patients with acute ischemic stroke due to an anterior circulation large vessel occlusion. Methods— Patients included in the MR CLEAN trial (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands; n=500) and MR CLEAN Registry (n=1488) were studied. Collateral status on baseline computed tomography angiography was scored from 0 (absent) to 3 (good). Multivariable ordinal logistic regression analyses were used to test the association of selected determinants with collateral status. Results— In total, 1988 patients were analyzed. Distribution of the collateral status was as follows: absent (7%, n=123), poor (32%, n=596), moderate (39%, n=735), and good (23%, n=422). Associations for a poor collateral status in a multivariable model existed for age (adjusted common odds ratio, 0.92 per 10 years [95% CI, 0.886–0.98]), male (adjusted common odds ratio, 0.64 [95% CI, 0.53–0.76]), blood glucose level (adjusted common odds ratio, 0.97 [95% CI, 0.95–1.00]), and occlusion of the intracranial segment of the internal carotid artery with occlusion of the terminus (adjusted common odds ratio 0.50 [95% CI, 0.41–0.61]). In contrast to previous studies, we did not find an association between cardiovascular risk factors and collateral status. Conclusions— Older age, male sex, high glucose levels, and intracranial internal carotid artery with occlusion of the terminus occlusions are associated with poor computed tomography angiography collateral grades in patients with acute ischemic stroke eligible for endovascular treatment.

Abstract Background and purpose Safety and predictors of rescue therapy in patients with acute ischemic stroke due to large artery atherosclerosis still remain unclear. This study aimed to test safety of rescue therapy and evaluate predictors of it after failed mechanical thrombectomy.Methods This retrospective study enrolled consecutively 245 patients with acute ischemic stroke treated by endovascular treatment from March 2016 to April 2019 in a single stroke center. We analyzed the clinical data and laboratory test for safety and predictors of rescue therapy. Binary logistic analysis was applied to confirm the independently relationship.Results There were totally 145 patients enrolled among 245 patients. Rescue therapy was independently associated with the excellent outcome [p=0.048, adjusted OR: 2.655, 95%CI: 1.008 – 6.989] and longer procedure time of endovascular treatment [p=0.004, adjusted OR: 3.722, 95%CI: 1.519-9.122], but there was no significance on complications and mortality. Prestrike incidence [p=0.004, adjusted OR:4.427, 95%CI:1.618-12.114], use of rt-PA [p=0.003, adjusted OR:4.792, 95%CI:1.688-13.602], tandem occlusion [p=0.001, adjusted OR:0.021, 95%CI:0.002-0.194], PLT [p=0.012, adjusted OR:3.234, 95%CI:1.289-8.113], P-LCR>42.3% [p=0.031, adjusted OR:0.132, 95%CI:0.021-0.827] were independent predictors of rescue therapy.Conclusions Rescue therapy for acute ischemic stroke due to large artery atherosclerosis costs more procedure time of endovascular treatment, but it can successfully recanalize the occlusive large artery and is independently related to the excellent clinical outcome without increasing ICH, sICH, reocclusion and others. Prestroke incidence, use of rt-PA, tandem occlusion, PLT and P-LCR may be independent predictors of rescue therapy in acute ischemic stroke due to large artery atherosclerosis.

Background: We report our single center experience of endovascular treatment of stroke by the technique of direct clot aspiration. Methods: From September 2013 to July 2014, from our prospectively gathered database, we reviewed 114 patients presenting with large vessels occlusion in the settings of acute ischemic stroke and treated with the ADAPT technique in first intention. Results: Hundred and fourteen patients (55 female and 54 male patients (mean age: 64 y.o) presented with a median NIHSS score of 15,9 (1-26). The localisation of arterial occlusion was the MCA in 52/114 (45%), the ICA in 16/114 (14%), a tandem occlusion in 35/114 (30,7%) and the vertebro basilar territory in 11/114 (9,65%). Procedures were performed under sedation in 66% of cases and general anesthesia in 33%. The aspiration technique alone was successful in achieving TICI 2b/3 in 48,2% of cases (55/114) with a mean of 2 passes. The additional use of stent retrievers improved the TICI 2b/3 revascularization rate to 87,5%. With aspiration alone, the average time from groin puncture to at least TICI 2b recanalization was 37 min (from clot contact to recanalisation: 17 min). Ninety day functional outcomes was available for 87/114 patients with 50% of good functional outcomes (mRS≤ 0-2) and 15% death (mRS 6). For the overal series there were 10 cases (8,7%) of procedural complications (one non occlusive dissection, 4 distal emboli, and 5 Subarachnoid hemorrhages) and 2 symptomatic intracerebral hemorrhages (2,5%). Discussion: The aspiration technique utilizing large bore aspiration catheters technique alone was effective in 48% of the cases being fast, safe and simple, but to achieve a recanalization rate of 87,5% it add to be completed by the use of stentrievers in the other cases. The relevance of this technique needs to studied in larger prospective multicentric studies.

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.

Background. The assessment of clinical manifestations in patients with acute pre-circular infarction is important for verification of the lesion, the choice of the treatment program, prediction of the stroke consequences. The purpose is to investigate the clinical, neurological, and neuroimaging features of lacunar and non-lacunar carotid infarctions in acute ischemic stroke and to assess their short-term consequences. Materials and methods. There was performed a clinical and radiological analysis of carotid infarction in 540 patients with acute ischemic stroke, which were divided into two groups: 155 patients were verified for infarcts in the cortex and white matter of the brain in the vasculature of the anterior and middle cerebral artery; in 385 patients, infarct foci were found in the area of the deep hemispheres of the brain (subcortical-capsular infarcts). Results. Clinical neuroimaging analysis of patients with ischemic stroke in the vasculature of the cortical branches of the anterior and middle cerebral arteries of the anterior circulatory basin showed that acute cerebral circulatory disorders caused the development of small cortical infarctions in 89 (57.4 %) patients and 65 (41 %) — lacunar infarction, in one patient (0.7 %) with occlusion of the proximal anterior cerebral artery — total infarction. The neurological clinical picture of infarcts of varying localization, which was determined by the location and size of the lesion, was described. Conclusions. The obtained results showed that the consequences of anterior circular infarctions depended on the localization of the lesion of the arterial area, the caliber of the infarction of the dependent artery, the size of the infarct locus. For the most part, these factors determined the background severity of neurological deficit after the development of acute ischemic stroke.
