Carotid intima‐media thickness – a potential predictor for rupture risk of intracranial aneurysms
ConclusionThere is an association between IMT and intracranial aneurysm rupture status at the time of aneurysm treatment. Carotid IMT can be a potential predictor of aneurysm rupture. IMT may thus be a possible adjunct in the risk assessment of aneurysm rupture, and a helpful tool in patient risk stratification and counseling.

A Little Good...
Abstract My grandmother used to say: "If a little'll do a little good, a lot'll do a lotta good." Unfortunately, it is not that simple with antiplatelet agents. Many relevant facts are well-established. In identifiable subgroups of patients who present with TIA or minor stroke, the risk of a subsequent stroke is high.(1-3) Most of this risk is incurred during the first few days after a warning event.(2) Aspirin and other antiplatelet agents can lower the risk of secondary stroke by approximately 12-22%.(4,5) In patients with acute coronary syndromes, another thrombotic disorder, dual antiplatelet therapy offers a ...

Carotid endarterectomy for symptomatic low-grade carotid stenosis
Conclusions: This study shows that CEA is a safe, effective, and durable treatment for patients with symptomatic low-grade carotid stenosis associated with unstable plaque. Patients had excellent protection against further ischemic events and survived long enough to justify the initial surgical risk. Plaque instability seems to play a major part in the onset of ischemic events, regardless the entity of lumen narrowing.

Diagnosis of stroke due to cocaine and its complications.
CONCLUSIONS. The consumption of cocaine is associated with cerebrovascular disease through a number of different mechanisms, which each give rise to different complications. By identifying these complications, correct management can be implemented. PMID: 23884871 [PubMed - in process]

Subluxation of the shoulder joint in stroke patients and the influence of selected factors on the incidence of instability.
Conclusions: 1. The clinical symptoms of stroke are the cause of subluxation in the shoulder joint. 2. Subluxation occurs more frequently in patients with a known presence of fluid in the subhumeral and subdeltoidbursae and in patients with reduced functional capacity. 3. The reduction of subluxation and bursal fluid was influenced by the exercise program and improved functional capacity. PMID: 23898003 [PubMed - in process]

Potential of magnetic resonance‐guided focused ultrasound for intracranial hemorrhage: an in vitro feasibility study
ConclusionsThese results demonstrate the feasibility of obtaining reproducible, rapid, efficient, and accurate blood clot lysis using the magnetic resonance‐guided focused ultrasound system. Further in vivo studies are needed to validate the feasibility of magnetic resonance‐guided focused ultrasound as a treatment modality for intracranial hemorrhage.

Closing the Loop: A 21-year Audit of Strategies for Preventing Stroke and Death Following Carotid Endarterectomy
The objective of this review was to identify causes of stroke/death after carotid endarterectomy (CEA) and to develop transferable strategies for preventing stroke/death after CEA, via an overview of a 21-year series of themed research and audit projects. Three preventive strategies were identified: (i) intra-operative transcranial Doppler (TCD) ultrasound and completion angioscopy which virtually abolished intra-operative stroke, primarily through the removal of residual luminal thrombus prior to restoration of flow; (ii) dual antiplatelet therapy with a single 75-mg dose of clopidogrel the night before surgery in additio...

Neonatal neuroimaging predicts recruitment of contralesional corticospinal tracts following perinatal brain injury
AimUnilateral perinatal brain injury may result in recruitment of ipsilateral projections originating in the unaffected hemisphere and development of unilateral spastic cerebral palsy (USCP). The aim of this study was to assess the predictive value of neonatal neuroimaging following perinatal brain injury for recruitment of ipsilateral corticospinal tracts. MethodNeonatal magnetic resonance imaging (MRI) and cranial ultrasound scans of 37 children (20 males, 17 females; median [range] gestational age 36 wks+4 [26+6–42wks+5] and birthweight 2312 g ([770–5230g]) with unilateral perinatal arterial ischaemic stroke (n=23) ...

Carotid Artery Free-Floating Thrombus Caused by Paradoxical Embolization From Greater Saphenous Vein Ascending Thrombophlebitis
We report a case of a young woman without cardiovascular risk factors who was admitted to our emergency department with listlessness and altered mental status. The clinical examination revealed right lower limb swelling. Magnetic resonance imaging and contrast-enhanced computed tomographic scans revealed a free floating thrombus of the left internal carotid artery (ICA) with a large bilateral frontal ischemic lesion. The diagnosis of a medium-sized PFO with moderate right-to-left contrast shunting was made after transesophageal echocardiography. No other cardiac sources for embolization were detected, while an ascending th...

Use of Transcranial Doppler (TCD) Ultrasound in the Neurocritical Care Unit
Transcranial Doppler (TCD) is a portable device that uses a handheld 2-MHz transducer. It is most commonly used in subarachnoid hemorrhage where cerebral blood flow velocities in major intracranial blood vessels are measured to detect vasospasm in the first 2 to 3 weeks. TCD is used to detect vasospasm in traumatic brain injury and post-tumor resection, measurement of cerebral autoregulation and cerebrovascular reactivity, diagnosis of acute arterial occlusions in stroke, screening for patent foramen ovale and monitoring of emboli. It can be used to detect abnormally high intracranial pressure and for confirmation of total...

Brainstem Stroke: Anatomy, Clinical and Radiological Findings
Ischemic brainstem strokes constitute 10% of all ischemic brain strokes. Hemorrhagic complications are associated with an especially poor prognosis. Associated symptomatology includes vertigo, cranial nerve symptoms, and crossed or uncrossed corticospinal tract findings. Advanced neuroimaging techniques have become essential in the decision-making process of brainstem stroke management and may provide a means to identify those patients who may benefit from thrombolysis. Because many of the recommendations are based on limited data, additional research on treatment of acute brainstem stroke is needed.

Predictors of Severity of Cerebral Vasospasm caused by Aneurysmal Subarachnoid Hemorrhage
Background: Cerebral vasospasm is one of the leading causes of poor outcome after aneurysmal subarachnoid hemorrhage. The risk factors for the development of vasospasm have been evaluated in many clinical studies. However, it remains unclear if vasospasm severity can be predicted. The purpose of this study was to determine if different demographic and clinical factors that appear to be predictors of vasospasm can also prognosticate the severity of cerebral vasospasm.Methods: We retrospectively analyzed consecutive patients with subarachnoid hemorrhage who underwent endovascular vasospasm treatment in a single center. In or...
