Head computed tomography (CT) with perfusion imaging has become crucial in the selection of patients for mechanical thrombectomy. In recent years, machine learning has rapidly evolved and found applications in a wide variety of health care tasks. We report our initial experiences with training a neural network to predict the presence and laterality of a perfusion deficit in patients with acute ischemic stroke. ⋯ The field of machine learning, powered by convolutional neural networks for the task of image recognition and processing, has quickly developed in recent years. We constructed an artificial neural network that can identify and classify the presence and laterality of a perfusion deficit on CT perfusion imaging.

We compared the mid-term efficacy and safety of anterior cervical discectomy and fusion (ACDF) using a Zero-Profile device for cervical degenerative disc disease (CDDD) with and without osteoporosis. ⋯ ACDF with the Zero-Profile device can be used as an effective and reliable treatment for single-level CDDD with osteoporosis.

Delayed cerebral vasospasm is an important cause of morbidity and mortality in patients with subarachnoid hemorrhage (SAH). This study aimed to assess the effects of Astragaloside IV (AS-IV) on delayed cerebral vasospasm after SAH. ⋯ AS-IV may attenuate delayed cerebral vasospasm after SAH through inhibition of TLR4/NF-κB-mediated inflammatory signaling pathways.

Review Case Reports
Embolization of Ruptured Distal Lenticulostriate Artery Aneurysms.
To describe the critical role of endovascular treatment and safety for the patients who presented with intraventricular hemorrhage owing to rupture of the distal lenticulostriate artery aneurysms. ⋯ Endovascular therapy is available and safe as a treatment option for distal lateral lenticulostriate artery aneurysms.

Multicenter Study Comparative Study
Prospective Comparative Study in Spine Surgery Between O-Arm and Airo Systems: Efficacy and Radiation Exposure.
Pedicle screw placement remains challenging. The present study focuses on the comparison between 2 intraoperative-based neuronavigation systems (O-Arm and AIRO) during thoracolumbar screw instrumentation. ⋯ Intraoperative computed tomography-based navigation is a major innovation that improves the accuracy of pedicle screw positioning with acceptable patient radiation exposure and reduced surgical team exposure.
