Prognosis of dolichoectasia in non-cardioembolic transient ischemic attack and minor stroke.

This study aimed to estimate the prognosis of dolichoectasia in non-cardioembolic transient ischemic attack (TIA) and minor stroke patients. Methods Data were derived from the imaging subgroup of patients in the Clopidogrel in High-risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial. Dolichoectasia was defined as ectasia (basilar artery diameter>4.5 mm) and dolichosis (either basilar artery bifurcation above the suprasellar cistern or lateral to the margin of the clivus or dorsum sellae). The prognosis included ischemic stroke recurrence and poor functional outcome (modified Rankin scale 2-6) at 12-month follow-up. The association of dolichoectasia with risk factors and prognosis of patients were assessed using multivariable Cox regression models. Results Overall, 1089 patients with magnetic resonance images in the CHANCE trial were included in this subanalysis. A total of 98 (9.0%) patients were detected with dolichoectasia, and 106 (9.7%) patients had a recurrent ischemic stroke at 12 months. Small artery occlusion (SAO) was more prevalent in patients with dolichoectasia compared with those without dolichoectasia (29.6% vs. 22.7%, hazard ratio [HR] 2.87, 95% confidence interval [CI] 1.59-5.17, p

Abstract Major efforts are currently made promoting neuronal plasticity and brain remodeling in the postacute stroke phase. Experimental studies evaluating new stroke therapies are mostly performed in rodents, which compared to humans exhibit a short lifespan. These studies widely employ young, otherwise healthy, rodents that lack the vascular risk factors and comorbidities of stroke patients. These risk factors compromise postischemic neurological recovery and brain plasticity and in several contexts reduce the brain responsiveness to recovery-inducing plasticity-promoting treatments. By examining risk factor mod...

This study is registered with Clinicaltrials.gov, NCT01335087 and is now closed.FindingsBetween April 25, 2011, and Feb 2, 2018, a total of 2834 patients with ACS had respiratory polygraphy, of whom 2551 (90·01%) were recruited. 1264 (49·55%) patients had OSA and were randomly assigned to the CPAP group (n=633) or the UC group (n=631). 1287 (50·45%) patients did not have OSA, of whom 603 (46·85%) were randomly assigned to the reference group. Patients were followed up for a median of 3·35 years (IQR 1·50–5·31). The prevalence of cardiovascular events was similar in the...

In order to assess a potential cardioembolic source an echocardiogram was performed revealing a large mass consistent with a thrombus in transit through a patent foramen ovale. Due to the high risk of systemic embolism emergent surgical thrombectomy was performed,...

TaylorAbstractIntracerebral haemorrhage (ICH) accounts for around 10–20% of all strokes and results from a variety of disorders. ICH is more likely to result in death or major disability than ischaemic stroke or subarachnoid haemorrhage. Rapid imaging allows early diagnosis and characterization of the localization and severity of the haemorrhage. Patients with significant acute ICH should be managed in a critical care unit. Treatment entails general supportive care, control of blood pressure an...

CONCLUSIONS: In our large series, the addition of a routine contrast-enhanced neck MRA to our pediatric stroke MR imaging protocol was of extremely low yield. We believe the use of neck MRA should reasonably be limited to cases in which abnormalities are initially detected on standard brain sequences or to patients with atypical presentation or recurrent pathology.

AbstractBackground and purposeMechanical thrombectomy (MT) improves early clinical outcome in patients with acute ischemic stroke but insights on determinants of long-term outcome after MT treatment are scarce.MethodsData from stroke patients with anterior circulation large vessel occlusion of a prospective MT registry (01/2014 –06/2017) of a large comprehensive stroke center were analyzed regarding clinical outcome between short- (3 months) and long-term (12 months) assessment reflected by a change of modified Rankin scores (∆mRS). Secondary endpoints included favorable long-term outcome (mRS 0–2)....
