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.

To evaluate surgical management of cavernous malformations (CMs) involving the medulla oblongata and to predict risk factors of postoperative respiratory dysfunction (RDF). ⋯ Postoperative RDF and CR deficits could commonly occur in patients with CMs involving the medulla oblongata. However, patients with fewer preoperative hemorrhages, small lesion size, and operation within 8 weeks of the last bleeding are prone to be associated with a reduced possibility of bad postoperative respiratory status.

Meningioma: The Tumor That Taught Us Neurosurgery.
The history of neurosurgery is ever fascinating. The journey has been tedious; nevertheless, in the landscape of success and failures we have become more efficient and polished. Skills were learned, innovations were made, and in the process we evolved. ⋯ Countless stories that testify the momentous role of meningioma in the process of evolution and reformation of neurosurgical techniques exist in the literature. With every step and every attempt at conquering this tumor, we reformed to be better surgeons, more skilled and more precise. In this paper we have walked down the lane of neurosurgery and paid a due tribute to this "necessary evil."

The surgical approach for the trigeminal nerve involves veins connected to the superior petrosal and tentorial sinus, and we should pay special attention to these veins. We investigated intraoperative and postoperative bleeding using our database. ⋯ Microvascular decompression for trigeminal neuralgia involves potential risks of intraoperative and postoperative bleeding.
