Fluid Attenuated Inversion Recovery

Introduction: Because acute fluid-attenuated inversion recovery vascular hyperintensities (FVH) represent disordered blood flow, FVH has been considered as a marker of major arterial occlusions. Contrary, the role of absence of FVH (negative-FVH) is unknown. Hypothesis: We hypothesized that negative-FVH may indicate chronic occlusion. Thus, we investigated the clinical characteristics and neuroimaging findings in patients with negative-FVH and major arterial occlusion. Methods: Consecutive acute stroke patients within 24 hours of onset and major arterial occlusion on magnetic resonance angiography (MRA) were studied. All patients were examined using serial angiography to evaluate the presence of recanalization. Patients were classified into two groups (NF: group without FVH, F: group with FVH). Results: Seventy-two patients (49 [68%] males, 76 [66-83] years) were enrolled. Thirty-six (50%) patients were treated with acute recanalization therapy, including the intravenous thrombolysis or endovascular therapy. On admission, 10 patients were NF group and 62 were F group. Initial National Institutes of Health Stroke Scale (NIHSS) score was 4 (2-8) in NF group and 10 (4-21) in F group (p=0.012). The rate of internal carotid artery occlusion was similar between NF and F group (20% vs. 29%, p=0.716). Serial angiography studies revealed that recanalization was achieved in only 1 (10%) of the 10 patients with NF group and 49 (79%) of the 62 patients with F group during hospitalization (p<0.001). When all patients divided into 2 groups based on the presence or absence of recanalization, patients with recanalization were younger (p=0.023), had higher NIHSS (p=0.008), earlier admission (p=0.014), higher prevalence of atrial fibrillation (p=0.010), and frequently treated with acute recanalization therapy (p=0.040). When multivariate regression analysis was conducted, that Negative-FVH (odds ratio 0.061, 95% CI 0.06-0.620, p=0.018) was a negative independent factor associated with recanalization during hospitalization. Conclusions: Negative-FVH was independently associated with no recanalization during hospitalization. Negative-FLAIR may present not acute occlusion but chronic occlusion.

PurposeThe absence of the susceptibility vessel sign (negative SVS) on gradient-recalled echo or susceptibility-weighted imaging (SWI) in thrombolytic therapy has not been well studied. Since positive and negative SVS may have different components, we aimed to investigate the difference in risk factors for clinical outcome between patients with positive and negative SVS.MethodsWe retrospectively examined clinical and imaging data from 85 consecutive patients with acute ischemic stroke with middle cerebral artery occlusion who underwent SWI before intravenous thrombolysis (IVT). We then examined the predictors of negative SVS and the risk factors for a poor outcome (defined as modified Rankin Scale score ≥3) 3 months after IVT in subgroup analysis.ResultsMultivariate regression analysis indicated that previous antiplatelet use (OR 0.076; 95% CI 0.007 to 0.847; p=0.036) and shorter time from onset to treatment (OR 1.051; 95% CI 1.003 to 1.102; p=0.037) were inversely associated with poor outcome in patients with negative SVS, while higher baseline National Institutes of Health Stroke Scale (NIHSS) score was associated with poor outcome in patients with positive SVS (OR 1.222; 95% CI 1.084 to 1.377; p=0.001).ConclusionsThe risk factors for clinical outcome after IVT in patients with negative SVS may differ from those with positive SVS.

Current Guidelines

The efficacy of intravenous thrombolysis and endovascular therapy and their favorable treatment outcomes have been established in clinical trials irrespective of age. Current guidelines do not recommend an age limit in selecting eligible patients for reperfusion treatment as long as other criteria are satisfied. A 103-year-old woman was admitted at our hospital within 1 h of stroke onset secondary to a left internal carotid artery terminus occlusion. On admission, her National Institutes of Health Stroke Scale (NIHSS) score was 30, with a small left thalamic diffusion restriction lesion on MRI. Her medical history included paroxysmal atrial fibrillation, prior myocardial infarction, hypertension, chronic kidney disease, and diabetes mellitus. Her pre-stroke modified Rankin Scale score was 0, and she was fully independent before stroke. Once intravenous thrombolysis was started, the patient successfully underwent mechanical thrombectomy, and thrombolysis in cerebral infarction-3 recanalization was achieved 225 min after symptom onset. She showed dramatic recovery (NIHSS score of 5 after 48 h) and was discharged on day 7 with a modified Rankin Score of 1. To our knowledge, our patient is the second oldest documented patient who successfully underwent bridging therapy for stroke.

Hospital Arrival

Background: It is unknown whether the effect of onset-­­to-door (OTD) time on clinical outcomes differs between ­patients with and without large artery occlusion (LAO) who undergo hyperacute recanalization therapy. Methods: Hyperacute recanalization therapy includes intravenous thrombolysis tissue-plasminogen activator (tPA), and endovascular therapy (EVT). Favorable clinical outcome was defined as modified Rankin Scale of ≤2 at discharge. Results: Among 164 patients, 117 (71%) patients received tPA, 86 (52%) received EVT, and 39 (24%) received tPA and EVT. One hundred and fifteen patients (70%) were classified into the LAO group and 49 (30%) into the non-LAO group. In the total cohort, multivariate regression analysis showed OTD time (OR 0.809 [95% CI 0.693–0.944], p = 0.007) was an independent factor related to the favorable outcome. Similarly, among patients with LAO, OTD was an independent negative factor for the favorable outcome (0.779 [0.646–0.940], p = 0.009). On the contrary, OTD was not associated with the favorable outcome (1.5 [0.7–2.5] vs. 1.7 [1.1–3.2], p = 0.155) in patients without LAO. This was confirmed with multivariate regression analysis, which did not show OTD to be an independent factor for the favorable outcome (0.900 [0.656–1.236], p = 0.516). Conclusion: The effect of early hospital arrival on clinical outcome differed between patients with and without LAO.

Progressive Occlusion

Spontaneous “non-moyamoya” arterial occlusion of the intracranial arteries is very unusual. Progressive occlusion of a major intracranial artery, independently from the etiology, can lead to the development of collateral arterial networks that supply blood flow to distal territories beyond the occlusion. These collateral arteries are typically small and conduct low flows, but the hemodynamic stress within them can lead to aneurysm formation within the collateral network. In this report we present a case of spontaneous internal carotid artery occlusion and collateral network aneurysm for the first time in the literature and discuss the main features of the etiology and endovascular treatment of this rare, challenging aneurysm.
