Meta Analyses

Background: COVID-19 has been shown to induce a hypercoagulable state thereby increasing the risk of arterial thrombosis resulting in Large Vessel Occlusion Stroke (LVOs) Objective: We performed a systematic review of published reports to study the clinical characteristics, and outcomes of COVID-19 acute ischemic stroke (AIS) patients with LVO treated with mechanical thrombectomy (MT) and compared them with historical controls. Methods: We conducted a systematic literature search from December 2019 to July 2020 using multiple combinations of keywords from PubMed and Ovid databases according to the PRISMA meta-analyses and systemic reviews guidelines and then pooled data from individual case series. We included studies where COVID -19 associated LVO cases were treated with MT and their clinical outcomes were reported. We then compared these findings with the historic patient data from the five landmark randomized MT trials, the Hermes collaborators (HC). Results: An initial search generated 12 studies but after excluding case reports and multiple reports comprising of the same series of patients, a total of five reports consisting of 51 patients were analyzed. The mean age of patients was 59 years (IQR 36-75), and 40 (78 %) were men. Median NIHSS on presentation was 20 (IQR 10-29). AIS with LVO was the presenting manifestation of COVID-19 in 16 (20%) of patients. Intracranial ICA was the most common site of occlusion found in 27 (53%) of patients with multi-territory occlusion in 10 (20 %). Final recanalization TICI ≥ 2b was achieved in 33 (64%) of patients but reocclusion was noted in 7 (14 %). Modified Rankin score (mRS) 0-2 was reported in 12 (23 %) of patients with 40 % in-hospital mortality. When compared to historic data from HC, COVID -19 patients were younger (59 vs 69 years), presented with a higher median NIHSS score (20 vs 17), and had a higher prevalence of ICA terminus occlusion (53% vs 21% ). Similarly, patient outcomes were poor in the COVID -19 group with mRs 0-2 in (23 % versus 46 %) and mortality (40 % vs 15 %) compared to Hermes group. Conclusion: COVID -19 AIS patients with LVO who underwent MT were younger, had multiple territory occlusions with a propensity for ICA terminus location, and had poor angiographic and clinical outcomes as compared to historic data.

Abstract Background and PurposeStroke is a drastic complication and a poor prognostic marker of COVID-19 disease which emphasizes the importance of early identification and management of this complication. In this case series, we describe our experience of mechanical thrombectomy of large vessel occlusions (LVO) in patients with COVID-19.MethodsWe performed a retrospective study of a series of confirmed COVID-19 patients who underwent endovascular thrombectomy for acute cerebrovascular ischemic disease with large vessel occlusion. Patient demographics, presentations, lab values, angiographic and clinical outcomes were also reviewed.ResultsThree COVID-19 patients with large vessel occlusion who underwent endovascular thrombectomy were identified in our multi-center institution. Two patients had respiratory symptoms prior presentation and one patient presented initially with clinical deficits. Two patients had anterior circulation occlusion in the middle cerebral artery territory vs one had posterior circulation occlusion in the basilar artery. There was good angiographic outcome post thrombectomy in all patients, however poor clinical outcomes noted with no significant improvement in neurological manifestations in comparison with baseline at presentation. All patients developed critically severe symptoms during hospitalization requiring intubation and one patient died of COVID-19 related respiratory failure.ConclusionIn this small case series, we noted worse clinical outcomes in COVID-19 related LVO stroke despite effective thrombectomy, which may be related to the underlying COVID-19 disease and/or the nature of clot in these patients.

The Impact

ObjectivePermissive hypertension may benefit patients with non-recanalized large vessel occlusion (nrLVO) post mechanical thrombectomy (MT) by maintaining brain perfusion. Data evaluating the impact of post-MT blood pressure (BP) levels on outcomes in nrLVO patients are scarce. We investigated the association of the post-MT BP course with safety and efficacy outcomes in nrLVO.MethodsHourly systolic BP (SBP) and diastolic BP (DBP) values were prospectively recorded for 24 hours following MT in consecutive nrLVO patients. Maximum, minimum, and mean BP levels were documented. Three-month functional independence (FI) was defined as modified Rankin Scale (mRS) scores of 0–2.ResultsA total of 88 nrLVO patients were evaluated post MT. Patients with FI had lower maximum SBP (160±19 mmHg vs 179±23 mmHg; P=0.001) and higher minimum SBP levels (119±12 mmHg vs 108±25 mmHg; P=0.008). Maximum SBP (183±20 mmHg vs 169±23 mmHg; P=0.008) and DBP levels (105±20 mmHg vs 89±18 mmHg; P=0.001) were higher in patients who died at 3 months while minimum SBP values were lower (102±28 mmHg vs 115±16 mmHg; P=0.007). On multivariable analyses, both maximum SBP (OR per 10 mmHg increase: 0.55, 95% CI 0.39 to 0.79; P=0.001) and minimum SBP (OR per 10 mmHg increase: 1.64, 95% CI 1.04 to 2.60; P=0.033) levels were independently associated with the odds of FI. Maximum DBP (OR per 10 mmHg increase: 1.61; 95% CI 1.10 to 2.36; P=0.014) and minimum SBP (OR per 10 mmHg increase: 0.65, 95% CI 0.47 to 0.90; P=0.009) values were independent predictors of 3-month mortality.ConclusionsOur study demonstrates that wide BP excursions from the mean during the first 24 hours post MT are associated with worse outcomes in patients with nrLVO.

Symptomatic Intracranial Hemorrhage

Background and purpose Successful reperfusion can be achieved in more than two-thirds of patients with usual large-vessel occlusion stroke causes treated with mechanical thrombectomy. However, the safety and outcomes after mechanical thrombectomy in the setting of large-vessel occlusion related to infective endocarditis is not known. In this study, we investigated the impact of mechanical thrombectomy in infective endocarditis patients on angiographic and clinical outcomes. Methods This was a multicenter study from five comprehensive stroke centers. We compared the outcomes of mechanical thrombectomy treated stroke patients due to infective endocarditis with patients presenting atrial fibrillation. Clinical outcomes included 90-day modified Rankin Scale, symptomatic intracerebral hemorrhage, and mortality. Results Between June 2013 and March 2019, 28 patients presenting large-vessel occlusion stroke due to IE were included. These cases were matched with 84 large-vessel occlusion stroke related to atrial fibrillation. Successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b/3) was obtained in 85.7%. Symptomatic intracranial hemorrhage, favorable outcome and mortality rates were respectively 8.0%, 25.9%, and 25.9%. In the case–control analysis, we demonstrated no difference in terms of successful reperfusion, procedural complication, symptomatic intracranial hemorrhage, and mortality rates. Three-month favorable outcome was less often achieved in the infective endocarditis group. Conclusions Mechanical thrombectomy of infective endocarditis patients presents similar safety and angiographic results compared to patients suffering from atrial fibrillation.

Objective:There are limited data evaluating the effect of post mechanical thrombectomy (MT) blood pressure (BP) levels on early outcomes of patients with large vessel occlusions (LVO). We sought to investigate the association of BP course following MT with early outcomes in LVO.Methods:Consecutive patients with LVO treated with MT during a 3-year period were evaluated. Hourly systolic BP (SBP) and diastolic BP (DBP) values were recorded for 24 hours following MT and maximum SBP and DBP levels were identified. LVO patients with complete reperfusion following MT were stratified in 3 groups based on post-MT achieved BP goals: <140/90 mm Hg (intensive), <160/90 mm Hg (moderate), and <220/110 mm Hg or <180/105 mm Hg when pretreated with IV thrombolysis (permissive hypertension). Three-month functional independence was defined as modified Rankin Scale score of 0–2.Results:A total of 217 acute ischemic stroke patients with LVO were prospectively evaluated. A 10 mm Hg increment in maximum SBP documented during the first 24 hours post MT was independently (p = 0.001) associated with a lower likelihood of 3-month functional independence (odds ratio [OR] 0.70; 95% confidence interval [CI] 0.56–0.87) and a higher odds of 3-month mortality (OR 1.49; 95% CI 1.18–1.88) after adjusting for potential confounders. In addition, achieving a BP goal of <160/90 mm Hg during the first 24 hours following MT was independently associated with a lower likelihood of 3-month mortality (OR 0.08; 95% CI 0.01–0.54; p = 0.010) in comparison to permissive hypertension.Conclusions:High maximum SBP levels following MT are independently associated with increased likelihood of 3-month mortality and functional dependence in LVO patients. Moderate BP control is also related to lower odds of 3-month mortality in comparison to permissive hypertension.

Background: Endovascular therapy has been proven effective for the treatment of large vessel occlusion strokes (LVOS). However, the feasibility and potential benefits of repeat thrombectomy for recurrent stroke is unclear. We aim to report our experience with repeat thrombectomy for recurrent LVOS. Methods: We reviewed our prospectively collected endovascular database for patients who underwent repeated mechanical thrombectomy. Baseline characteristics, procedural data and outcomes were evaluated. Patients with repeat thrombectomy were compared to patients with single thrombectomy. For patients with repeat thrombectomy, imaging and procedural variables were compared between first and last procedures. Results: Out of 697 patients treated within the study period, 15 patients (2%) had repeat thrombectomies (14 treated twice and one thrice). The mean age was 63 ± 15 years and 40% were males. The median time between the first and last procedure was 18 (1-278) days. Cardioembolism (66%) was the most common etiology, followed by intracranial atherosclerosis (13%) and large vessel atherosclerosis (6%). At 90 days after the last thrombectomy, 60% of patients achieved a modified Rankin Scale score of 0-2 and 20% were deceased. There were no statistically significant differences in demographics, stroke severity, time from last known normal to puncture, reperfusion rates, hemorrhagic complications, good clinical outcomes and mortality between patients who underwent repeat thrombectomy and those who had a single thrombectomy. Conclusion: In properly selected patients suffering recurrent LVOS, repeated mechanical thrombectomy appears to be feasible and safe. A previous thrombectomy should not discourage aggressive treatment as these patients may achieve similar rates of good clinical outcomes as those who undergo single thrombectomy.
