premiums for physicians. 12 , 20 Given the increasing emphasis on tort reform within the political sphere, and an increase in the rate at which brain aneurysms have been detected over the past several decades, 1 , 5 we sought to characterize the reasons for malpractice litigation related to the treatment of these lesions in the US, over a 30-year period. In addition, we hoped to better characterize the nature of these cases to better inform practicing physicians about the ways in which they can minimize these occurrences. Methods Institutional review board approval was

the real usefulness of a simulator, studies of its predictive validity are necessary. 11 Studies comparing different types of brain aneurysm surgical simulation have reported both face and content validity. 17 To our knowledge, concurrent and predictive validity have never been studied. These parameters refer to task-completing differences between experienced professionals and novices, the degree that 1 simulator correlates with previously described ones, and the end-point efficacy of simulators when one uses it to practice real situations. 18 The objectives of

Medical Association (AMA) to recommend that patient education materials be written at a reading level no higher than the 6th grade. 38 An increase in the use of magnetic resonance angiography and computed tomography angiography has resulted in a spike in the rate of aneurysm detection. 5 In this study we assessed the readability of online patient education materials about brain aneurysms that had been published by academic institutions. Methods A Google search was performed in 2016 using the key term “brain aneurysm.” Cerebrovascular education materials were

S ince the early 1990s, treatment of brain aneurysms has increasingly involved the use of the endovascular detachable coils first described by Guglielmi. 21 The endovascular approach has become an established and reliable technique for the treatment of certain types of aneurysms, particularly in persons who are at high risk if open surgical intervention is performed, and for lesions in anatomical locations that are difficult to access via a direct approach such as the basilar apex. 35 , 47 The long-term outcome of aneurysms treated with endovascular

N eurosurgical simulation has been explored, but few options are available to learn and practice brain aneurysm microsurgery. 1 , 3 To date, the human placenta model has been the only training tool with predictive validity for such surgery, 5 , 13 and the parameters used in evaluation were subjective, based on experts’ opinion. 5 The OSATS (Objective Structured Assessment of Technical Skills) 11 was the first scale reported for evaluation of surgical performance. Despite the inclusion of the word “objective” in its the name, the OSATS relies on the opinion of

T he discrepancy between the prevalence of brain aneurysms (as high as 5% or 10–15 million in the US population alone) and the incidence of aneurysmal rupture (∼ 30,000 cases identified annually in this country) leads investigators to infer that some brain aneurysms are more prone to rupture than others. 11, 32 Despite diagnostic and therapeutic advances, it is currently estimated that one half of persons afflicted with aneurysmal rupture—SAH—will die or become markedly disabled as a result of the original hemorrhage or a major complication such as rebleeding

I ntracranial saccular aneurysms are acquired lesions, accounting for ~ 80% of all nontraumatic SAHs. Several uncommon heritable disorders are associated with brain aneurysms, including autosomal-dominant polycystic kidney disease, 3 Marfan syndrome, 17 Ehlers–Danlos syndrome Type IV, 4 hereditary hemorrhagic telangiectasia, 11 pseudoxanthoma elasticum, multiple endocrine neoplasia Type I, and neurofibromatosis Type 1. 16 Outside of these rare heritable disorders, population-based 8 , 18 and nonpopulation-based 10 , 12–14 data suggest that there is

D evelopment of flexible self-expanding stents and stent-assisted coil occlusion of aneurysms facilitate endovascular treatment of wide-necked aneurysms arising in the brain. 2 , 5 , 9 , 15 The stent placement across the opening of a wide-necked aneurysm provides a good mechanical support, which helps to achieve denser coil packing and decreasing coil herniation or protrusion into the parent artery. The stent placement, in general, induces an alteration of intraaneurysmal hemodynamics. 3 , 7 , 8 In fact, there have been reports that some brain aneurysms

gain in treatment durability has promising implications for the pediatric population. In this paper, we present our early experience in the treatment of 3 pediatric brain aneurysms using the Pipeline embolization device (PED; ev3). To our knowledge, this is the first successful series of PED placements in children reported in the medical literature. Case Reports Case 1 History and Examination An 11-year-old girl, 13 kg in weight, with a history of Majewski osteodysplastic primordial dwarfism Type II (MOPD Type II), was known to have multiple
