Lobar Hemorrhage

Background: Baseline volume, spot sign, and coagulation status all predict early hematoma expansion (HE) in intracerebral hemorrhage (ICH). However, the role of ICH location on HE remains unclear. We hypothesized that lobar-located ICH would facilitate HE as it provides a larger potential volume for expansion as compared to deep locations. However, due to the close proximity of critical structures and increased risk of ventricular rupture, we also hypothesized that deep ICH would have a paradoxically increased risk of mortality and morbidity. Our objective was to assess the effect of lobar vs. non-lobar hemorrhage on HE and clinical outcome. Methods: We analyzed data from the prospective multicentre PREDICT study where patients with ICH presenting to hospital under 6 hours of symptom onset received a baseline CT, CTA, 24 hour follow-up CT, and 90-d mRS. ICH location was categorized as lobar vs deep, and primary outcomes were significant HE (>6mL) and poor clinical outcome (mRS >3). Multivariable regression with stepwise selection was used to adjust for relevant covariates. Sensitivity analysis was conducted by expanding the inclusion criteria to include patients who died or were treated with Factor VIIa and/or surgery prior to follow-up CT. Results: Among 302 patients meeting the inclusion criteria, lobar hemorrhage was associated with increased hematoma expansion >6mL (p=0.003), poor clinical outcome (p=0.011) and mortality (p=0.017). When adjusted for covariates, lobar hemorrhage independently predicted significant hematoma expansion (aOR 2.3 [95% CI: 1.2-4.4], p=0.02). Sensitivity analysis included a total of 353 patients and lobar location was no longer significantly associated with poor outcome (p=0.198). This appeared to be related to a higher proportion of IVH in the excluded population (33% Primary vs. 65% Excluded, p<0.001). Conclusion: Lobar hemorrhage led to expansion and poor clinical outcome in the primary analysis population. Sensitivity analysis of the excluded population revealed that deep bleeds are associated with a higher degree of mortality and morbidity, likely due to a higher frequency of IVH. Our findings suggest that baseline ICH location should be considered for risk stratification algorithms.

Introduction: Infarct in new territory (INT) is a known complication of endovascular therapy. We assessed the prevalence, predictors and clinical relevance of INT Methods: We included patients from the ESCAPE-NA1: a multicenter, international randomized study that assessed the efficacy of intravenous nerinetide in patients with acute ischemic stroke who underwent EVT within 12 hours from onset. All imaging was re-evaluated, and INT was defined by presence of infarct in new vascular territory, outside the baseline target occlusion(s) on follow up CT and MRI. INT’s were classified by maximum diameter (<2mm, 2-20mm and >20mm) and location. Results: Of 1099 analyzed patients in ESCAPE NA1, 107 had INT (9.7%, mean age 67 years, 51.4% females). There were no differences at baseline in those with vs without INT. Most INTs (75.7%) were angiographically occult and 41(38.3%) were > 20mm. The most common INT territory was the ACA alone or in combination with MCA/PCA (30.3%). The presence of emboli in new territory angiographically was significantly associated with INT (OR 16.39, 95%CI 8.14-33.09). Alteplase use, balloon guide catheter use, nerinetide and initial occlusion site did not predict INT. INT patients had higher final median infarct volumes compared to non-INT (44.5cc vs 23.3cc, P<0.001). Large INT (diameter of >20mm) were associated with poor clinical outcome compared to INT (<2mm) OR (mRS 0-2) 0.17, 95%CI 0.05-0.55). Conclusion: Infarcts in new territory are common and are associated with poor outcome.

Dissecting Aneurysms

Introduction : Acute dissecting aneurysms are among the uncommon causes of subarachnoid hemorrhage. Established endovascular treatment options include parent artery occlusion and stent‐assisted coiling, but appear to be associated with an increased risk of ischemic stroke. reconstruction of the vessels with flow diverters is an alternative therapeutic option. Methods : This is a retrospective analysis of 53 consecutive acutely ruptured dissecting aneurysms treated with flow diverters. The primary end point was favorable aneurysm occlusion, defined as OKM C1‐3 and D . Secondary end points were procedure‐related complications and clinical outcome. Results : 23 aneurysms (43.4%%) arose from the intradural portion of the vertebral artery, 10 (18.8%) were located on the posterior inferior cerebellar artery and 3 (5.6%) posterior cerebral artery, 7 (13.2%) MCA, (18.8%) ICA . 45 aneurysms presented by SAH while 8 presented by Ischemic manifestation. Flow diverter placement was technically successful in all cases . immediate postoperative rerupture occurred in two case (3.7%), thromboembolic complications in 3 cases (5.7%). Median clinical follow‐up was 640 days and median angiographic follow‐up was 690 days. ten patients (18.9%) with poor‐grade subarachnoid hemorrhage died in the acute phase. Favorable clinical outcome (modified Rankin scale ≤2) was observed in 27 of 53 patients (51%) and a moderate outcome (modified Rankin scale 3/4) was observed in 12 of 53 patients (22.6%). All aneurysms showed complete occlusion at follow‐up. Conclusions : Flow diverters might be a feasible, alternative treatment option for acutely symptomatic dissecting aneurysms and may effectively prevent rebleeding in ruptured aneurysms.

Anterior Ankle Impingement

Objective To determine potential predictive associations between patient-/lesion-specific factors, clinical outcome and anterior ankle impingement in patients that underwent isolated autologous matrix-induced chondrogenesis (AMIC) for an osteochondral lesion of the talus (OLT). Design Thirty-five patients with a mean age of 34.7 ± 15 years who underwent isolated cartilage repair with AMIC for OLTs were evaluated at a mean follow-up of 4.5 ± 1.9 years. Patients completed AOFAS (American Orthopaedic Foot and Ankle Society) scores at final follow-up, as well as Tegner scores at final follow-up and retrospectively for preinjury and presurgery time points. Pearson correlation and multivariate regression models were used to distinguish associations between patient-/lesion-specific factors, the need for subsequent surgery due to anterior ankle impingement and patient-reported outcomes. Results At final follow-up, AOFAS and Tegner scores averaged 92.6 ± 8.3 and 5.1 ± 1.8, respectively. Both body mass index (BMI) and duration of symptoms were independent predictors for postoperative AOFAS and Δ preinjury to postsurgery Tegner with positive smoking status showing a trend toward worse AOFAS scores, but this did not reach statistical significance ( P = 0.054). Nine patients (25.7%) required subsequent surgery due to anterior ankle impingement. Smoking was the only factor that showed significant correlation with postoperative anterior ankle impingement with an odds ratio of 10.61 when adjusted for BMI and duration of symptoms (95% CI, 1.04-108.57; P = 0.047). Conclusion In particular, patients with normal BMI and chronic symptoms benefit from AMIC for the treatment of OLTs. Conversely, smoking cessation should be considered before AMIC due to the increased risk of subsequent surgery and possibly worse clinical outcome seen in active smokers.

Abstract Background Diabetes is an independent risk factor for atrial fibrillation (AF), which is associated with increases in mortality and morbidity, as well as a diminished quality of life. Renal involvement in diabetes is common, and since chronic kidney disease (CKD) shares several of the same putative mechanisms as AF, it may contribute to its increased risk in individuals with diabetes. The objective of this study is to identify the relationship between CKD and the rates of newly-diagnosed AF in individuals with diabetes taking part in a screening program using a self-applied wearable electrocardiogram (ECG) patch. Materials and methods The study included 608 individuals with a diagnosis of diabetes among 1738 total actively monitored participants in the prospective mHealth Screening to Prevent Strokes (mSToPS) trial. Participants, without a prior diagnosis of AF, wore an ECG patch for 2 weeks, twice, over a 4-months period and followed clinically through claims data for 1 year. Definitions of CKD included ICD-9 or ICD-10 chronic renal failure diagnostic codes, and the Health Profile Database algorithm. Individuals requiring dialysis were excluded from trial enrollment. Results Ninety-six (15.8%) of study participants with diabetes also had a diagnosis of CKD. Over 12 months of follow-up, 19 new cases of AF were detected among the 608 participants. AF was newly diagnosed in 7.3% of participants with CKD and 2.3% in those without (P < 0.05) over 12 months of follow-up. In a univariate Cox proportional hazard regression analysis, the risk of incident AF was 3 times higher in individuals with CKD relative to those without CKD: hazard ratios (HR) 3.106 (95% CI 1.2–7.9). After adjusting for the effect of age, sex, and hypertension, the risk of incident AF was still significantly higher in those with CKD: HR 2.886 (95% CI 1.1–7.5). Conclusion Among individuals with diabetes, CKD significantly increases the risk of incident AF. Identification of AF prior to clinical symptoms through active ECG screening could help to improve the clinical outcomes in individuals with CKD and diabetes.

Abstract Heart failure (HF) remains the most common major cardiovascular complication arising in pregnancy and the postpartum period. Mothers who develop HF have been shown to experience an increased risk of death as well as a variety of adverse cardiac and obstetric outcomes. Recent studies have demonstrated that the risk to neonates is significant, with increased risks in perinatal morbidity and mortality, low Apgar scores, and prolonged neonatal intensive care unit stays. Information on the causal factors of HF can be used to predict risk and understand timing of onset, mortality, and morbidity. A variety of modifiable, nonmodifiable, and obstetric risk factors as well as comorbidities are known to increase a patient's likelihood of developing HF, and there are additional elements that are known to portend a poorer prognosis beyond the HF diagnosis. Multidisciplinary cardio‐obstetric teams are becoming more prominent, and their existence will both benefit patients through direct care and increased awareness and educate clinicians and trainees on this patient population. Detection, access to care, insurance barriers to extended postpartum follow‐up, and timely patient counseling are all areas where care for these women can be improved. Further data on maternal and fetal outcomes are necessary, with the formation of State Maternal Perinatal Quality Collaboratives paving the way for such advances.

Background and purposeFlow diverters are sometimes used in the setting of acutely ruptured aneurysms. However, thromboembolic and hemorrhagic complications are feared and evidence regarding safety is limited. Therefore, in this multicenter study we evaluated complications, clinical, and angiographic outcomes of patients treated with a flow diverter for acutely ruptured aneurysms.MethodsWe conducted a retrospective observational study of 44 consecutive patients who underwent flow diverter treatment within 15 days after rupture of an intracranial aneurysm at six centers. The primary end point was good clinical outcome, defined as modified Rankin Scale score (mRS) 0–2. Secondary endpoints were procedure-related complications and complete aneurysm occlusion at follow-up.ResultsAt follow-up (median 3.4 months) 20 patients (45%) had a good clinical outcome. In 20 patients (45%), 25 procedure-related complications occurred. These resulted in permanent neurologic deficits in 12 patients (27%). In 5 patients (11%) aneurysm re-rupture occurred. Eight patients died resulting in an all-cause mortality rate of 18%. Procedure-related complications were associated with a poor clinical outcome (mRS 3–6; OR 5.1(95% CI 1.0 to 24.9), p=0.04). Large aneurysms were prone to re-rupture with rebleed rates of 60% (3/5) vs 5% (2/39) (p=0.01) for aneurysms with a size ≥20 mm and <20 mm, respectively. Follow-up angiography in 29 patients (median 9.7 months) showed complete aneurysm occlusion in 27 (93%).ConclusionFlow diverter treatment of ruptured intracranial aneurysms was associated with high rates of procedure-related complications including aneurysm re-ruptures. Complications were associated with poor clinical outcome. In patients with available angiographic follow-up, a high occlusion rate was observed.

Abstract Acute ischemic stroke (IS) and transient ischemic attack (TIA) are associated with raised von Willebrand factor (VWF) and decreased ADAMTS13 activity (ADAMTS13Ac). Their impact on mortality and morbidity is unclear. We conducted a prospective investigation of the VWF-ADAMTS13 axis in 292 adults (acute IS, n = 103; TIA, n = 80; controls, n = 109) serially from presentation until &gt;6 weeks. The National Institutes of Health Stroke Score (NIHSS) and modified Rankin scale (mRS) were used to assess stroke severity. Presenting median VWF antigen (VWF:Ag)/ADAMTS13Ac ratios were: IS, 2.42 (range, 0.78-9.53); TIA, 1.89 (range, 0.41-8.14); and controls, 1.69 (range, 0.25-15.63). Longitudinally, the median VWF:Ag/ADAMTS13Ac ratio decreased (IS, 2.42 to 1.66; P = .0008; TIA, 1.89 to 0.65; P &lt; .0001). The VWF:Ag/ADAMTS13Ac ratio was higher at presentation in IS patients who died (3.683 vs 2.014; P &lt; .0001). A presenting VWF:Ag/ADAMTS13Ac ratio &gt;2.6 predicted mortality (odds ratio, 6.33; range, 2.22-18.1). Those with a VWF:Ag/ADAMTS13Ac ratio in the highest quartile (&gt;3.091) had 31% increased risk mortality. VWF:Ag/ADAMTS13Ac ratio at presentation of ischemic brain injury was associated with higher mRS (P = .021) and NIHSS scores (P = .029) at follow-up. Thrombolysis resulted in prompt reduction of the VWF:Ag/ADAMTS13Ac ratio and significant improvement in mRS on follow-up. A raised VWF:Ag/ADAMTS13Ac ratio at presentation of acute IS or TIA is associated with increased mortality and poorer functional outcome. A ratio of 2.6 seems to differentiate outcome. Prompt reduction in the ratio in thrombolysed patients was associated with decreased mortality and morbidity. The VWF:Ag/ADAMTS13Ac ratio is a biomarker for the acute impact of an ischemic event and longer-term outcome.

Introduction: Ischemic strokes with tandem occlusions are associated with a poor prognosis. Recent studies demonstrating the effectiveness of endovascular treatment for large vessel occlusions have shown less impressive results in patients with tandem occlusions than in those with isolated intracranial occlusions. Besides, the indications and effects of ICA stenting remain unclear. Hypothesis: To determine the factors associated with favorable outcome at 3-month in this subtype of AIS. Methods: From a prospectively gathered registry, we analyzed the data of 70 consecutive patients who underwent mechanical endovascular treatment for acute stroke with tandem occlusions from November 2011 to August 2014. Clinical (including demographics, NIHSS, and stroke etiology), imaging (including DWI-ASPECTS), and endovascular treatment data were assessed and reviewed in consensus by two observers. Good clinical outcome was defined as a modified Rankin Scale (mRS) of ≤2 at 3-month follow-up. The mRS at 3 months follow-up was available in 67 patients. Results: At 3-month follow-up, 33 of 67 (49.3%) patients had a good clinical outcome and 34 (50.8%) had a poor clinical outcome, including 9 deaths (13.4%). Lower NIHSS (initial, at day 1, and at discharge) and successful recanalization (TICI 2b-3) were associated with a good clinical outcome (P<0.05). There were no statistically significant differences between patients with a good or poor clinical outcome in terms of intravenous tissue plasminogen activator use, delay between symptom onset and recanalization, and endovascular technique, including the ICA stenting. Conclusions: Despite the recent randomized control trials demonstrating the effectiveness of thrombectomy, there is still a research gap about tandem occlusions. This subtype of stroke, which usually responds poorly to intravenous thrombolysis, is also difficult to treat by endovascular means.
