Acute Vestibular Syndrome

Abstract: Introduction and aim: To diagnose acute vestibular syndrome (AVS) in a prospective study by a new bedside test (providing 1A evidence) based on oculomotor analysis and assessment of hearing loss. To assess the frequency of central and peripheral causes of acute vestibular syndrome in the emergency room. To establish the diagnostic accuracy of acute cranial computed tomography as compared to oculomotor analysis done by video oculography goggles and audiometry. Method: Between 1st March 2016 and 1st March 2017 we documented 125 patients (62 women, 63 men, average age 53 years) in the emergency room of the Petz Aladár County Teaching Hospital using the above bedside and instrumental testing. Diagnosis was verified by cranial magnetic resonance imaging. Results: According to the results of the instrumental examination in AVS in 67% we found a peripheral cause and in 33% a central pathology. In 62% isolated posterior circulation stroke manifested itself by isolated vertigo without additional focal signs and the acute cranial computed tomography showed negative results in 96%. The instrumental examination increased diagnostic accuracy by making the diagnosis of isolated inferior semicircular canal vestibular neuritis possible. Conclusions: The new bedside oculomotor test is suitable for the diagnosis of posterior circulation stroke manifesting with isolated vertigo in early cases, when the routine neuroradiologic methods have a lower sensitivity or are not available.

Ventricular Response

Catheter ablation of atrial fibrillation (AF) has established itself as a safe and proven rhythm control strategy for selected patients with AF over the past decade. Thromboembolic complications of catheter ablation are becoming rare in anticoagulated patients with a risk of stroke reported as 0.3%. A particular challenge is posed by clinical presentation due to ischaemic stroke involving the posterior circulation following catheter ablation because of its substantial differences from the carotid territory stroke, making the timely diagnosis and treatment very difficult. It is crucial to keep an index of clinical suspicion in patients presenting with neurological deficits related to vertebrobasilar circulation following ablation. We describe the case of a man who presented with dizziness and palpitations after radiofrequency catheter ablation of AF. He was found to be in AF with a rapid ventricular response. His dizziness was initially attributed to the cardiac dysrhythmia. As his symptoms continued despite heart rate control, he underwent further investigations and was eventually diagnosed with a posterior circulation stroke resulting in left cerebellar infarction. He was treated with antiplatelet therapy and improved significantly over the following few days. We review and present an up-to-date brief literature review on the complications of catheter ablation of AF and describe pathophysiology, clinical features, diagnosis and treatment options for posterior circulation stroke after AF ablation. This case aims to raise awareness among clinicians about posterior circulation stroke after AF ablation.

Abstract Background Intravenous thrombolysis (IVT) with alteplase is the first-line therapy for acute ischemic anterior and posterior circulation strokes (ACS and PCS). Knowledge about safety and efficacy of IVT in posterior circulation stroke is deficient as most of the Egyptian studies either assessed IVT outcome in comparison to conservative therapy or its outcome in anterior circulation stroke only. Therefore, our aim was to compare the relative frequency and outcome after intravenous thrombolysis in anterior versus posterior circulation stroke patients presenting to stroke centers of Ain Shams University hospitals (ASUH). Results A total of 238 anterior circulation stroke and 61 posterior circulation strokes were enrolled, onset-to-door and door-to-needle time were statistically insignificant. NIHSS showed comparable difference at all time points despite higher scores along anterior circulation stroke; 90-day modified Rankin Scale (mRS) showed significant improvement in both groups from mRS >2 to ≤2 with a better percentage along posterior circulation stroke patients. There was insignificant difference for either incidence of death or intracranial hemorrhage (ICH) between the two groups. Conclusion IVT significantly reduced NIHSS for both anterior and posterior circulation stroke along different studied time points. Meanwhile, a higher percentage of patients with posterior circulation stroke had a better mRS outcome at 90 days.
