Abstract Objective: To identify the predictors of ischemic events secondary to cervicocerebral artery dissection (CAD). Methods: Consecutive patients with cervicocerebral artery dissection from 2010 to 2017 were registered as study subjects, who were classified as patients with and without ischemic events. Clinical data were collected prospectively, such as demographics, vascular risk factors, headache and neck pain, dissection site and laboratory test. A case-control study was performed to compare the clinical data between two groups. Results: A total of 130 patients with cervicocerebral artery dissection were included, in which 70.0% (91/130) suffered from ischemic events, including 81 ischemic strokes and 10 transient ischemic attacks. There were 46.2% (42/91) and 25.6% (10/39) of the artery dissections located in the anterior circulation in the CAD patients with and without ischemic events respectively (p=0.029). The average level of HDL was (1.14±0.38) mmol/L in the CAD patients with ischemic events, and (1.28±0.48) mmol/L in the CAD patients without ischemic events (p=0.083). However, no significant differences were found in the other clinical data. Multivariate logistic regression analysis showed that there was a positive correlation between anterior circulation and ischemic events (OR=3.204, 95% CI 1.305-7.863, p=0.011) and HDL level was negatively correlated with ischemic events (OR=0.335, 95% CI 0.130-0.867, p=0.024) in CAD patients. Conclusion: Ischemic events are common complications of cerebrovascular disease in CAD patients, especially for those with an artery dissection located in the anterior circulation and low serum HDL level.

BackgroundFlow diversion (FD) is a common treatment modality for complex intracranial aneurysms. A major concern regarding the use of FD is thromboembolic events (TEE). There is debate surrounding the optimal antiplatelet regimen to prevent TEE. We aim to evaluate the safety and efficacy of ticagrelor as a single antiplatelet therapy (SAPT) for the prevention of TEE following FD for complex aneurysm treatment.MethodsA retrospective review of a prospectively maintained neuroendovascular database at three endovascular centers was performed. Patients were included if they had an intracranial aneurysm that was treated with FD between January 2018 and September 2019 and were treated with ticagrelor as SAPT. Primary outcomes included early (within 72 hours post-procedure) and late (within 6 months) ischemic events.ResultsA total of 24 patients (mean age 47.7 years) with 36 aneurysms were eligible for analysis, including 15 (62.5%) females. 14 (58.3%) patients presented with subarachnoid hemorrhage. 35 aneurysms arose from the anterior circulation and 1 from the posterior circulation. 23 aneurysms had a saccular morphology, whereas 7 were fusiform and 6 were blister. For the treatment of all 36 aneurysms, 30 procedures were performed with 32 FD devices. Procedural in-stent thrombosis occurred in 2 cases and was treated with intra-arterial tirofiban without complications. Aneurysm re-bleeding was reported in 1 (4.2%) patient. There were no reported early or late TEE. Three patients discontinued ticagrelor due to systemic side effects.ConclusionTicagrelor is a safe and effective SAPT for the prevention of TEE after FD. Large multicenter prospective studies are warranted to validate our findings.

Abstract Background Spontaneous Coronary Artery Dissection (SCAD) is an important cause of acute coronary syndrome particularly in young-middle aged women. Revascularisation is challenging due to an underlying disrupted and friable coronary vessel wall leading to widely reported worse outcomes than for atherosclerotic coronary disease. Therefore, a conservative approach where possible is favoured however in some cases haemodynamic instability, ongoing ischaemia and reduced distal flow mandates consideration of revascularisation. Purpose To compare SCAD survivors managed with PCI or conservatively in terms of presentation characteristics, complications and long-term outcomes. Methodology and results 226 angiographically confirmed SCAD survivors (95% female,47±9.7yrs) who underwent PCI were compared in a case control study with two hundred and twenty-five angiographically confirmed SCAD survivors (92% female, 49±9.9yrs) who were conservatively managed. Patients were recruited from UK, Spanish and Dutch SCAD registries and both groups were well matched in terms of baseline demographics. Those treated with PCI were more likely to present with proximal SCAD (30.8% vs 7.6% P<0.01) and ST elevation myocardial infarction (STEMI) or cardiac arrest with reduced flow (32.3% vs 6.3% P<0.01). Intervention was performed with stents in 72.4%, plain old balloon angioplasty in 21.1% and wiring in 6.4% of cases and more often for multi-segment disease (40.8% vs 26.3% P<0.01). In cases with initial reduced flow undergoing PCI an improvement in flow was seen in 83%. Analysis of UK PCI cases (n=144) reveal complications in 56 (38.8%). However, when assessed for significance defined by a reduction in flow in a proximal/mid vessel, stent extension into left main stem, iatrogenic dissection requiring PCI and CABG as a consequence of PCI only 13 cases (9%) met criteria. Iatrogenic dissection accounts for the majority (76.9%). SCAD lesion length was associated with presence of complications (P=0.025). There was a non-significant trend towards major adverse cardiovascular events (MACE) occurring more frequently in those undergoing PCI (18% vs 11% P=0.067) driven by revascularisation (5% vs 1% P=0.036). Median follow up was 2.7 years. Conclusions PCI in SCAD is often performed in higher risk patients; in those presenting with reduced flow, the majority demonstrate improvement. Importantly whilst overall complication rates were similar to those widely reported, clinically significant complications were low. Multivariate modelling will reveal factors associated with complications to aid future decision making in this challenging patient group.

Abstract Background Development of type 2 diabetes (T2D) is common in patients with heart failure (HF), but knowledge of future cardiovascular events is lacking. Purpose We compared risk of heart failure hospitalization (HFH) or death versus ischemic events in real-life HF patients with new-onset T2D, prevalent T2D and no T2D. Methods Using the Danish nationwide registers, we identified all patients with HF between 1998–2016. The patients were separated in two different HF cohorts based on the status of T2D. One cohort consisted of HF patients with either prevalent or absent T2D at the time of HF diagnosis. The other cohort consisted of HF patients, who developed new-onset T2D, included at time of diagnosis. The two HF cohorts were analyzed separately. Outcomes for both cohorts were analyzed as time-to-first event as either an ischemic event (i.e. composite outcome of fatal and non-fatal myocardial infarction, stroke, and peripheral artery disease), HFH, or event-free death (not related to HFH or the ischemic event). For each cohort, we estimated the five-year absolute risk of ischemic event, HFH and event-free death, along with five-year risk ratio of HFH or event-free death versus ischemic events. Effects among subgroups were investigated by stratifying both cohorts based on age, gender and comorbidities present at inclusion. Results A total of 139,264 HF patients were included between 1998 and 2016, of which 29,078 (21%) patients had prevalent T2D at baseline. A total of 11,819 (8%) developed new-onset T2D and were included in the second cohort. The median duration of time between HF diagnosis and new-onset T2D diagnosis was: 4.1 years (IQR:1.5; 5.8). The absolute five-year risk of an ischemic event in patients with new-onset T2D, prevalent T2D and no T2D was: 17.9% (95% confidence interval (CI): 17.2; 18.6), 26.1% (95% CI: 25.6; 26.7), and 18.8% (95% CI:18.6; 19.0). Corresponding estimates for HFH were: 31.5% (95% CI: 30.6; 32.3), 33.6% (95% CI: 33.0; 34.2), and 30,7% (95% CI: 30.5; 31.0). The absolute five-year risk of event-free death among patients with new-onset T2D, prevalent T2D and no T2D was: 20.9% (95% CI: 20.2; 21.7), 18.9% (95% CI:18.4; 19.3), and 18.6% (95% CI: 18.4; 18.8) (see Figure). The five-year risk ratio of experiencing HFH or event-free death versus an ischemic event was: 2.9 (95% CI: 2.8; 3.1), 2.0 (95% CI:2.0; 2.1), and 2.6 (95% CI: 2.6; 2.7) for patients with new-onset T2D, prevalent T2D and no T2D, respectively. Similar results of absolute and relative risk were present across all subgroups. Conclusion In our population of HF patients, 8% developed new-onset diabetes. Development of T2D in patients with HF increases the risk of HFH and mortality three-fold. The increased risk of new-onset T2D is higher than the importance of prevalent T2D in patients with HF.

Introduction: Few studies have investigated the association between pretreatment DWI-ASPECTS and functional outcome after stent-retriever thrombectomy in patients with acute anterior circulation stroke. Hypothesis: Patients with acute stroke and DWI-ASPECTS <7 might have a similar chance of a good outcome compared to those with a higher DWI-ASPECTS, if they are treated with a stent-retriever thrombectomy in a short time window. However, this hypothesis has not been tested. Thus, this study aimed to investigate the impact of DWI-ASPECTS on functional outcome in patients with acute anterior circulation stroke who received a stent-retriever thrombectomy. Methods: We retrospectively analyzed the clinical and DWI data from 171 patients with acute anterior circulation stroke who were treated with stent-retriever thrombectomy within 6 hours of symptom onset. The DWI-ASPECTS was assessed by two readers. A good outcome was defined as a modified Rankin Scale score of 0-2 at 3 months. Results: The median DWI-ASPECTS was 7 (interquartile range, 6-8). Receiver operating characteristics analysis revealed an ASPECTS ≥ 7 was the optimal cut-off to predict a good outcome at 3 months (area under the curve=0.57; sensitivity, 75.3%; specificity, 34.4%). The rates of good outcome, symptomatic hemorrhage, and mortality were not different between high DWI-ASPECTS (scores of 7-10) and intermediate (scores of 4-6) groups. In patients with an intermediate DWI-ASPECTS, good outcome was achieved in 46.5% (20/43) of patients with successful revascularization (modified TICI 2b or 3), whereas no patients without successful revascularization had a good outcome ( P =0.016). In multivariate logistic regression analysis, independent predictors of good outcome were age and successful revascularization. Conclusions: Our study suggested that treatment outcomes were not different between patients with a high DWI-ASPECTS and those with an intermediate DWI-ASPECTS who underwent stent-retriever thrombectomy for acute anterior circulation stroke. Thus, patients with an intermediate DWI-ASPECTS otherwise eligible for endovascular therapy should not be excluded for stent-retriever thrombectomy or stroke trials.

Background: Cervical artery dissections (CAD) are among the most common causes of stroke in young and middle-aged adults. In contrast to carotid dissections (CD) and anterior circulation ischemia, the clinical manifestations of vertebral dissections (VD) and posterior circulation ischemia are often nonspecific (e.g. dizziness and ataxia), and thus a high index of suspicion is necessary for diagnosis. Therefore, the reported incidence of VD in the medical literature is likely to be an underestimation. Methods: With IRB approval, we conducted a retrospective chart review study using the Neurology Database of Houston Methodist Neurological Institute to identify all patients diagnosed with CAD between August 2011 and March 2015. All patients presented with cerebral ischemia (TIA or stroke). The diagnosis of CAD was made by a stroke neurologist and was based on clinical presentation and appropriate vascular imaging studies. Patients with incidental CAD and those with questionable diagnosis of CAD clinically and radiographically were excluded. Over the studied period (32 months), a total of 677 TIA patients and 3230 stroke patients were admitted to our tertiary-care hospital. Results: Of 52 patients with CAD-related TIA or ischemic stroke, there were 34 patients (65.4%) with VD and 18 patients (34.6%) with CD. The average age of presentation is 47 years (range: 18 to 75 years) for VD patients and 51 years (range: 34 to 78 years) for CD patients. CAD was slightly more common in males, with 18 VD patients (52.9%) and 10 CD patients (55.5%) in our studied population were males. Out of 30 patients with VD who underwent both noninvasive vascular imaging (MRA or CTA) and cerebral angiogram, dissection was detected on noninvasive imaging in 10 patients (33.3%). On the other hand, out of 13 patients with CD who had both types of imaging modalities, dissection was detected on noninvasive testing in 8 patients (61.5%). Conclusions: VD was detected approximately twice as frequently as CD in our study. Both conditions are slightly more common in men with an average age of presentation is about 50 years. In addition, our data suggest that noninvasive testing is more likely to diagnose carotid dissection (in two-third of cases) than vertebral dissection (in one-third of cases).

A 16-year-old Korean boy presented with acute onset vertigo, dysphagia and gait ataxia of 16 hours duration. He had history of headache and neck pain along with transient vertigo during a water slide ride 12 days before presentation. CT brain showed left cerebellar and left lateral medullary infarcts. CT angiography showed left vertebral dissection with occlusion of left posterior inferior cerebellar artery. A 52-year-old Indian man, presented with acute onset global aphasia and right hemiparesis within 3 hours of onset of symptoms. He received intravenous tissue plasminogen activator (tPA) with partial improvement in his symptoms. He had headache and neck pain since 2 weeks, ever since he had a water slide ride. CT brain was normal, while the CT angiogram showed left carotid dissection. Cervical artery dissection has been reported with roller coaster rides and rarely with delayed presentations. Delayed presentation of cervical artery dissection after water rides have not been reported.
