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

outcomes data regarding IFD devices for the treatment of brain aneurysms. Compared with prior meta-analyses that have focused on WEB embolization of ruptured aneurysms, this review provides a comprehensive analysis of both ruptured and unruptured aneurysms treated using a variety of IFD devices. 29 – 31 At a mean radiographic follow-up duration of 15.7 months, complete occlusion was achieved in 58.2% of IFD-treated aneurysms with residual neck and aneurysm rates of 27.4% and 9.7%, respectively. However, there was significant study heterogeneity in the pooled data (p < 0

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

Endovascular Procedure An FDS implant was considered the preferred therapeutic strategy in 72 cases of acutely ruptured brain aneurysms and was implanted after failed coiling attempts in 4 cases. In all patients, FDS implantation was used as stand-alone therapy; no patient was treated with coils in addition to the FDS. Endovascular treatment was performed on SAH day 1 in 14 patients

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
