“…Lenticulostriate arteries (LSAs) are among the largest perforating arteries in the brain. These vessels originate from the MCA and range from 2 to 12 in number [33]. ICA occlusion leads to a decrease in anterograde blood flow in the LSAs.…”

Background: Treatment for acute ischemic stroke due to large vessel occlusion (LVO) with mild symptoms is under discussion. Although most patients have good outcomes, some patients deteriorate and have unfavorable results. Imaging findings that predict the prognosis of LVO with mild symptoms are needed to identify patients who require treatment. In this study, we focused on watershed infarctions (WSIs), because this clinical phenomenon quite sensitively reflects changes in cerebral blood flow. The purpose of this study was to assess positive rates of WSI on MRI findings in patients with internal carotid artery (ICA) occlusion, and compare WSI-positive rates between patients divided according to their clinical course. Methods: We retrospectively collected data of 1,531 patients who presented with acute ischemic stroke between June 2006 and July 2019. Among them, we chose symptomatic ICA occlusion patients with a past history of atrial fibrillation who were treated conservatively. We divided these patients into two groups, those with maintenance or improvement in their NIHSS score after hospitalization, and those whose NIHSS score worsened. We compared WSI-positive rates between these two groups. Results: Thirty-seven of the 1,531 patients were included in this study. Of them, total NIHSS score was maintained or improved in 8 patients (group A), 3 of whom (37.5%) had internal watershed infarctions (IWIs). In group B, consisting of patients whose NIHSS score worsened by > 2 at 7 days from symptom onset, 24 (82.8%)

“…Overall, PED placement across perforating lenticulostriate arteries remains safe, probably due to the discrepancy between the wire size of the PED (30 m) and the diameter of lenticulostriate arteries (mean, 480 m; range, 100-1280 m). 27 Furthermore, in a computational model, Appanaboyina et al 25 observed that the coverage of 90% of the perforating vessel ostium reduced Ͻ10% of the flow through the inlet. These data suggest that even if 3 wires cross a perforator ostium with a diameter of 100 m, the coverage of the orifice area will never be Ͼ90%.…”

BACKGROUND AND PURPOSE: Flow-diverter technology has proved to be a safe and effective treatment for intracranial aneurysm based on the concept of flow diversion allowing parent artery and collateral preservation and aneurysm healing. We investigated the patency of covered side branches and flow modification within the parent artery following placement of the Pipeline Embolization Device in the treatment of intracranial aneurysms.

“…Correlation of radiologic and surgical anatomy is often difficult, particularly in the submillimeter environment of microneurosurgery. 9 Neuroradiologists are often forced to make educated guesses on the location of the aneurysm if it is truly intradural or the relationship of a vascular structure to surrounding tissues without the luxury of direct visualization. The main objective of this study was to describe a technique that allows neurosurgery residents to understand and correlate the radiologic and surgical anatomy.…”

“…Neuroanatomical and microsurgical training have become an integral part of neurosurgical training in institutions of excellence. [1][2][3][4][5][6][7][8][9] Cadaver dissections simulating complex neurosurgical approaches help the training of residents with respect to surgical neuroanatomy, improve manual dexterity, and facilitate the development of new microsurgical techniques. Knowledge of the complex anatomy of the cerebral vasculature coupled with a precise and accurate microsurgical technique is the mainstay for success in cerebrovascular surgery.…”

“…Knowledge of the complex anatomy of the cerebral vasculature coupled with a precise and accurate microsurgical technique is the mainstay for success in cerebrovascular surgery. 9 The well-described technique of injecting colored silicone into the cerebral vessels has been demonstrated to facilitate the identification and dissection of the cerebral vessels from the surrounding tissues. 1,5,6,10,11 In most centers, this technique is the basis for training, planning, practicing, developing, and refining neurosurgical approaches.…”

Background and Study Aim To enhance the visualization of the intracranial vasculature of cadavers under gross examination with a combination of imaging modalities. Material and Methods A total of 20 cadaver heads were used to test two different perfusion techniques. First, fixed cadaver heads were perfused with water; second, fresh cadavers were perfused with saline and 10% formalin. Subsequently, brains were removed and fixed. The compounds used were silicone rubber, silicone rubber mixed with powdered barium sulfate, and silicone rubber mixed with tantalum dioxide prepared by the first perfusion technique and gelatin mixed with liquid barium prepared with the second technique. Conventional X-ray imaging, computed tomography (CT), dynamic computed tomography (dCT), and postprocessing three-dimensional (3D) images were used to evaluate all the heads. Results Gelatinized barium was better visualized when compared with tantalum dioxide in conventional X-ray images. The blood vessels injected with either tantalum dioxide or gelatinized barium demonstrated a higher enhancement than the surrounding soft tissues with CT or dCT. The quality of the 3D reconstruction of the intracranial vasculature was significantly better in the CT images obtained from the gelatinized barium group. Conclusions Radiologic examinations of the heads injected with gelatinized barium facilitates the 3D understanding of cerebrovascular anatomy as an important tool for neuroanatomy training.
