Background and Purpose: The recognition of clinical features of transient vestibular symptoms (TVSs) preceding posterior circulation stroke (PCOS) would be informative to discriminate dizziness/vertigo due to vertebrobasilar transient ischemic attack from the acute transient vestibular syndrome. We sought to determine the prevalence and characteristics of TVSs preceding PCOS. Methods: We performed a prospective multicenter observational study that had recruited 447 patients with PCOS from referral-based 4 university hospitals in Korea. We investigated the timing, pattern, frequency, duration, and accompanying neurological symptoms of TVSs during the 3 months preceding PCOS. Results: The prevalence of TVSs preceding PCOS was 12% (55/447) during the previous 3 months. The TVSs preceding PCOS occurred within 1 week (33%), between 1 week and 1 month (16%), or between 1 and 3 months (51%). The TVSs were mostly dizziness/vertigo with (36%) or without (60%) imbalance, while the remaining 4% had an isolated imbalance. The dizziness/vertigo was spinning in 38% and was aggravated during head position in 45%. The duration of TVSs was mostly a few seconds (55%) or minutes (38%). Approximately 72% of the patients with PCOS had TVSs 1 to 5 times, while 16% had >10 times. Accompanying neurological symptoms, including headache, tinnitus, limb weakness, sensory change, dysarthria, visual field defect, and diplopia, were reported in 11%. Conclusions: Preceding TVSs can occur in 12% of PCOS during the previous 3 months. Isolated dizziness/vertigo of unknown cause needs to be considered as a vertebrobasilar transient ischemic attack symptom, especially in patients with vascular risk factors. The characteristics of isolated vestibular symptom in vertebrobasilar transient ischemic attacks is highly variable and atypical compared with other transient ischemic symptoms.

Ischemic Attack

Ischemic stroke and transient ischemic attack (TIA) are the most common cerebrovascular disorder and leading cause of death in China. The Effective secondary prevention is the vital strategy for reducing stroke recurrence. The aim of this guideline is to provide the most updated evidence-based recommendation to clinical physicians from the prior version. Control of risk factors, intervention for vascular stenosis/occlusion, antithrombotic therapy for cardioembolism, and antiplatelet therapy for noncardioembolic stroke are all recommended, and the prevention of recurrent stroke in a variety of uncommon causes and subtype provided as well. We modified the level of evidence and recommendation according to part of results from domestic RCT in order to facility the clinical practice.

Background and purpose: We aimed to investigate the role of perfusion MRI parameters (TTP: time to peak, CBF: cerebral blood flow, CBV: cerebral blood volume) as a prognostic factor for the risk of stroke recurrence or cardiovascular outcome in patients with transient ischemic attack (TIA) or minor stroke. Methods: We retrospectively reviewed TIA or minor stroke patients who underwent our stroke MRI protocol (DWI, perfusion MRI, and MRA) in a consecutively collected stroke registry. Primary outcome was nonfatal stroke recurrence and secondary outcome was cardiovascular composite outcome. Multivariate analysis was used to examine the association of perfusion MRI parameters and angiographic findings with the risk of stroke recurrence and cardiovascular event. Results: Of the 326 patients who met inclusion criteria, we identified 15(4.6%) nonfatal strokes and 25(7.7%) cardiovascular composite events during the first 1 year after the index TIA or minor stroke. The presence of regional delayed perfusion on TTP maps (p=0.002) and regional hyperperfusion on CBV maps (p<0.001) were associated with recurrent stroke. In MRA images, concomitant stenosis of the intracranial arteries and/or extracranial carotid arteries was associated with cardiovascular events (p=0.009). Using multivariate cox proportional hazard analysis, presence of regional hyperperfusion on CBV remained an independent predictor of recurrent stroke (HR 10.82, 95% CI 4.19-38.67, p<0.001) and cardiovascular event (HR 6.30, 95% CI 2.67-18.25, p<0.001). The AUC of the CBV maps was also greater than other parameters for the prediction of stroke recurrence (AUC=0.701, 95% CI 0.54-0.86) and cardiovascular composite outcome (AUC=0.628, 95% CI 0.50-0.76). Conclusions: Increased CBV on perfusion MRI, representing the hemodynamic status of postischemic hyperperfusion, could be more useful than other perfusion parameters in predicting poor prognosis of TIA or minor stroke patients.

Patients with symptomatic carotid stenosis benefit from revascularization. The risk of recurrent stroke is highest during the early period after a transient ischemic attack or stroke. Carotid endarterectomy and carotid stenting are options for treatment and should be considered within the first 2 weeks if feasible.
