1. Parallels in the evolution of x-ray angiographic systems and devices used for minimally invasive endovascular therapy Charles Strother - DSA, invented by Dr. Charles Mistretta at UW-Madison, was the technology which enabled the development of minimally invasive endovascular procedures. As DSA became widely available and the potential benefits for accessing the cerebral vasculature from an endovascular approach began to be apparent, industry began efforts to develop tools for use in these procedures. Along with development of catheters, embolic materials, pushable coils and the GDC coils there was simultaneous development and improvement of 2D DSA image quality and the introduction of 3D DSA...

Pituitary adenomas are a common intracranial neoplasm, usually demonstrating a benign phenotype. They can be classified according to pathological, radiological or clinical behaviour as typical, atypical or carcinomas, invasive or noninvasive, and aggressive or nonaggressive. Prolactinomas account for 40-60% of all pituitary adenomas, with dopamine agonists representing the first-line treatment and surgery/radiotherapy reserved for drug intolerance/resistance or in neuro-ophthalmological emergencies. We present the case of a 62-year-old man with an apparently indolent prolactin-secreting macroadenoma managed with partial resection and initially showing a biochemical response to cabergoline...

In our current medical practice, an increasing number of specialists now have access to radiology technical platforms in order to perform imaging-guided procedures. Although knowledge about the current guidelines and radiation protection devices is a pre-requisite for the use of radiation, the preventive measures are often more or less strictly followed, leading to chronic daily exposure to significant doses of radiation and large accumulated lifetime exposures. Aortic intervention, electrophysiology, and neuro intervention in particular can result in large doses to the operators...

To meet the needs of critically ill patients with time-sensitive needs, the University of Maryland Medical Center (UMMC) created the Critical Care Resuscitation Unit (CCRU), a six-bed, short-stay ICU designed to accelerate care to resource-heavy patients who require immediate evaluation and treatment. The CCRU is modeled after UMMC's trauma resuscitation unit, but with resources and staff geared toward non-trauma, critically ill patients, many of whom require life-saving care. The unit is largely staffed by emergency providers who have undergone additional training in critical care...

BACKGROUND: Diffuse brainstem glioma is a devastating disease with very poor prognosis. The most commonly used radiological treatment is conventional fractionated radiation. So far, there is no meta-analysis or systematic review available that assesses the benefits or harms of radiation in people with diffuse brainstem glioma. OBJECTIVES: To assess the effects of conventional fractionated radiotherapy (with or without chemotherapy) versus other therapies (including different radiotherapy techniques) for newly diagnosed diffuse brainstem gliomas in children and young adults aged 0 to 21 years...

OBJECTIVE Early rehabilitation is effective in an array of acute neurological disorders but it is not established as part of treatment guidelines after aneurysmal subarachnoid hemorrhage (aSAH). This may in part be due to the fear of aggravating the development of cerebral vasospasm, which is the most feared complication of aSAH. The aim of this study was to evaluate the effect of early rehabilitation and mobilization on complications during the acute phase and within 90 days after aSAH. METHODS This was a prospective, interventional study that included patients with aSAH at the neuro-intermediate ward after aneurysm repair...

INTRODUCTION: Epistaxis secondary to a ruptured cavernous-carotid aneurysm that has eroded into the sphenoid sinus is a life-threatening condition. When it is unilateral, balloon or coil embolization of the parent vessel should be considered. When bilateral, coiling the aneurysm to gain hemostasis followed by stent insertion after anticoagulation has been shown to be successful in achieving stabilization of the aneurysm wall whilst maintaining flow through the artery. CASE REPORT: We present a case of epistaxis secondary to giant bilateral cavernous-carotid aneurysm...

Brain abscesses occur as an uncommon complication of bacterial meningitis in the neonatal period. A 34 weeks preterm at-risk neonate presented with abnormal breathing pattern and inability to maintain the oxygen saturation in room air. Magnetic resonance imaging (MRI) study revealed intra-parenchymal brain abscesses in the left basal ganglion and bilateral fronto-parietal regions. Intravenous piperacillin - tazobactam was commenced and continued for 6 weeks in Neonatal Intensive Care Unit. No surgical intervention was required...

We herein report on a patient with a cerebral aneurysm located at the petrous portion of the internal carotid artery (ICA). An 18-year-old male, previously diagnosed with neurofibromatosis, was referred to our emergency service complaining of severe headache, pulsatile tinnitus, nausea, and vomiting which occurred suddenly. Neuro-radiological studies including computed tomography and magnetic resonance imaging of the cerebral artery showed a large aneurysm arising from the petrous segment of the left ICA. He was treated with a neuro-interventional technique such as intra-arterial stenting and coil embolization for the aneurysm...

The authors empirically evaluated the context of intra-procedural physician-patient communication during imaging-guided procedures in a radiology/neuroradiology interventional clinical framework. Different intra-procedural communicative scenarios are reported.They conclude that the quality of intra-procedural physician-patient communication should be considered an important element of individual and team ethical and professional behaviour, able to strongly influence the therapeutic alliance. As for the whole medical communication strategy, an approach which takes into account the psychological and cultural background of the individual patient is preferred...

The clinical and neuroimaging characteristics of brain infections related to Propionibacterium acnes are not well-characterized, making early diagnosis and treatment a challenge. More recently, life-threatening central nervous system infections with P. acnes are being reported with increasing frequency as complications of neurointerventional procedures. We present a rare case of P. acnes cerebritis that occurred as a sequela of bare platinum aneurysm coiling and a contaminant of percutaneous angiographic intervention...

A 47-year-old Indian woman with dark hair developed dramatic alopecia of the occipito-vertical area two weeks after a fluoroscopically-guided endovascular procedure for treatment of cerebral aneurysm. There was spontaneous repopulation of hair in 14 weeks. Neuro-radiological intervention procedures are becoming commoner by the day in India, and the rare but documented possibility of such reactions occurring in patients should be kept in mind by the treating surgeon as well as dermatologist. Necessary counseling regarding this uncommon side-effect is of essence, especially when the radiation dose exceeds 3 Gy...

Although clinical involvement by interventional radiologists in the care of their patients was advocated at the inception of the specialty, the change into the clinical paradigm has been slow and patchy for reasons related to pattern of practice, financial remuneration or absence of training. The case for the value of clinical responsibilities has been made in a number of publications and the consequences of not doing so have been manifest in the erosion of the role of the interventional radiologists particularly in the fields of peripheral vascular and neuro intervention...

Imaging cerebral infarction in first few hours after the onset of clinical symptoms is a challenge. The role of stroke imaging underwent a paradigm shift from confirmation of infarction from and exclusion of hemorrhage to the detection of the tissue at risk that may be rescued with restoration of circulation. Computed tomography (CT) is generally performed before starting the therapy in order to exclude the presence of bleeding and tumors. Although CT may show findings of infarction as early as 3-6 hours after ictus 30% of CT scans are normal in the first few hours after ischemic insult...

INTRODUCTION: Recognition of severe forms of posterior reversible encephalopathy syndrome (PRES) has improved. Management of these patients remains challenging, particularly in patients with the combination of edema and hemorrhage. METHODS: A prospective inpatient neuro-intensive care database was queried for patients with PRES. Malignant PRES was diagnosed by clinical assessments (GCS less than 8 and clinical decline despite standard medical management for elevated intracranial pressure) and radiographic criteria (edema with associated mass effect; brain hemorrhage exerting mass effect; effacement of basal cisterns, transtentorial, tonsillar, or uncal herniation)...
