We sought to assess general aspects of endovascular neurosurgery training, practice, and management for the treatment of intracranial aneurysms, arteriovenous malformations, acute ischemic stroke, and extracranial or intracranial occlusive disease within neurosurgery training and practice in the United States. ⋯ Our findings provide a snapshot of current neurosurgical endovascular practices in the United States.

To describe an approach to the analysis of deep brain stimulation (DBS) of the subthalamic nucleus (STN) using a hidden semi-Markov model (HsMM) and early results of the analysis of microelectrode recordings for STN DBS. ⋯ Further clinical work must be done; however, based on these data, HsMMs may be best suited to computer-assisted anatomic delineation for DBS.

Direct surgery for complex internal carotid artery (ICA) aneurysms can be difficult. In certain situations, sacrificing the parent artery is a unique way to obliterate the aneurysm and extracranial-to-intracranial (EC-IC) bypass is indispensable to prevent postoperative cerebral ischemia. This article discusses the indications for direct ICA occlusion, and the strategies, techniques, and outcomes in a series of patients treated for complex ICA aneurysms in a single institution. ⋯ Balloon occlusion test combined with computed tomographic perfusion can be an efficient way to evaluate the compromised cerebrovascular reserve in patients with complex ICA aneurysms after ICA occlusion. In conjunction with EC-IC bypass, ICA proximal occlusion or trapping can be an effective treatment strategy.
