Aortic dissection is a rare and life-threatening event. While pain is the most common symptom of aortic dissection, it may be absent in ten percent of patients and present with a myriad of symptoms suggestive of a diverse range of other conditions. A high index of clinical suspicion is mandatory for the accurate and rapid diagnosis of aortic dissection. We report a 25-year-old woman with aortic...

Sir, Verbal mutism is described as the speechless state in a cognitively alert patient, without buccolingual apraxia. It has been a well-documented complication of resective surgery for posterior fossa tumors, especially in children. 1,2 However, there are only few reports of posterior fossa mutism that are not due to neuro-trauma or neuro-surgical trauma. 3-5 We report the case of transient mu...

Air pollution is potential environmental risk factors for stroke. There is strong association between short term exposure to air pollution and admission to hospital for stroke and mortality from stroke. These associations were strongest in low and middle income countries, suggesting the need for policy changes to reduce personal exposure to air pollutants. Ambient sulfur dioxide (SO2) is consid...

BACKGROUND AND PURPOSE The purposes of this study were to evaluate and review the risk factors and clinical features of patients with posterior circulation stroke involving mesencephalon and neighboring structures and to describe the clinical syndromes according to the mesencephalic arterial territory involved. METHODS We studied all patients with acute posterior circulation stroke involving ...

CONTEXT The microsurgical anatomy of the posterior circulation is very complex and variable. Surgical approaches to this area are considered risky due to the presence of the various important blood vessels and neural structures. AIMS To document the microsurgical anatomy of the posterior circulation along with variations in the Indian population. MATERIALS AND METHODS The authors studied 25...

One in five strokes affects the posterior circulation. Diagnosing posterior circulation stroke can be challenging, as the vascular anatomy can be variable, and because presenting symptoms are often non-specific and fluctuating. Nevertheless, making the correct diagnosis is important, as these strokes have a high chance of recurrence, can be life threatening, and can lead to equally life-threate...

INTRODUCTION The intracranial vascular anatomical variations, although rare, represent a interesting field of research, since many anomalous variants are possible and in most cases they remain asymptomatic. The capability of the cerebral circulation to adapt to several flow changes is confirmed by the fact that in several cases these anatomical variation compensate for an eventual unsuccessful ...

A 6‐year‐old female presented with sudden‐onset right‐sided hemiparesis with motor aphasia for the past 7 days. Magnetic resonance imaging of the brain [Figure 1a] revealed acute infarct in the left parietooccipital region. Magnetic resonance angiogram (MRA) [Figure 1b] and computed tomography angiogram (CTA) [Figure 2] showed narrowing of bilateral supraclinoid internal carotid arteries (ICAs)...

BACKGROUND AND PURPOSE Limited data exist on childhood posterior circulation arterial ischemic stroke (PCAIS). We describe clinical and radiological features of childhood PCAIS to determine whether there are differences in infarct topography, vascular abnormalities, risk factors, and stroke subtypes when compared to adults. METHODS Children with radiologically confirmed PCAIS were prospective...

The objective of this paper was to analyse the technical and clinical outcome in patients receiving endovascular treatment for posterior circulation intracranial aneurysms at Royal Perth Hospital. The case notes and angiograms of 35 patients with ruptured and unruptured posterior circulation aneurysms treated by endovascular coil occlusion between 1992 and 1998 were included in the study. The d...
