Evaluating Deep Learning Techniques for Detecting Aneurysmal Subarachnoid Hemorrhage: A Comparative Analysis of Convolutional Neural Network and Transfer Learning Models.

Objective: Machine learning and deep learning techniques offer a promising multidisciplinary solution for subarachnoid hemorrhage (SAH) detection. The novel transfer learning approach mitigates the time constraints associated with the traditional techniques and demonstrates a superior performance. This study aims to evaluate the effectiveness of convolutional neural networks (CNNs) and CNN-based transfer learning models in differentiating between aneurysmal SAH and nonaneurysmal SAH.

Aim: To evaluate the effect of osteoplastic pterional craniotomy on temporal hollowing and its sequelae.

Material And Methods: A total of 97 patients who underwent pterional craniotomy for an aneurysm were analyzed retrospectively. Of these 97 patients, 63 underwent surgery via the conventional pterional approach and 34 underwent surgery via the osteoplastic pterional approach.

Influence of Spinopelvic Alignment on the Clinical Outcomes Following Decompression Surgery for Lumbar Stenosis.

Introduction The role of sagittal spinopelvic alignment in lumbar spinal stenosis (LSS) patients and its potential influence on post-decompression surgery outcomes is a topic of growing interest. Lumbar spinal stenosis is a prevalent degenerative condition, and with an aging population, the frequency of surgical interventions for LSS has risen. While decompression surgery aims to relieve symptoms, the potential impact of preoperative spinopelvic alignment on postoperative results remains controversial.

The Role of Computed Tomographic Angiography in Predicting the Development of Vasospasm Following Ruptured Intracranial Aneurysm Microsurgery.

Introduction Following subarachnoid hemorrhage, cerebral vasospasm is the primary cause of morbidity and death. The aim of this study is to predict the development of vasospasm by detecting changes in vessel diameter after surgery using computed tomography angiography. Methods We retrospectively evaluated the patients who underwent aneurysm clipping due to a bleeding aneurysm between 2019-2022.

Dynamic Lateral Semisitting Position for Supracerebellar Approaches: Technical Note and Case Series.

Background: It has always been a matter of debate which position is ideal for the supracerebellar approach. The risk of venous air embolism (VAE) is the major deterrent for surgeons and anesthesiologists, despite the fact that sitting and semisitting positions are commonly used in these operations.

Objective: To demonstrate a reduction on the risk of VAE and tension pneumocephalus throughout the operation period while taking advantages of the semisitting position.

Cerebrospinal fluid-dissemination of a ovarian clear cell carcinoma: A leptomeningial carcinomatosis with diagnostic challenges.

Metastases from ovarian cancer to the central nervous system (CNS) are rare, in particular, isolated leptomeningeal metastases (LM) are extremely rare. The gold standard in the diagnosis of leptomeningeal carcinomatosis (LC) is the detection of malignant cells in cerebrospinal fluid (CSF) cytology. A 58-year-old woman diagnosed with ovarian cancer 2 years ago underwent lumbar puncture and CSF cytology in recent months due to new weakness, loss of strength in the lower extremities, and speech disorders.

Spinal Schwannomas: A Proposal for a New Classification to Aid Surgical Planning.

Background The treatment of spinal schwannomas, which is the most common nerve sheath tumor, is total microsurgical resection. The localization, size and relationship with the surrounding structures of these tumors are crucial in terms of preoperative planning. A new classification method is presented in this study for the surgical planning of spinal schwannoma.

Peritumoural Oedema as a Predictor of Overall Survival for Patients with Posterior Fossa Metastases.

Objective: To analyse the relationship between peritumoural oedema volume and tumour volume in relation to the impact of metastatic posterior fossa tumour survival rates.

Study Design: An observational study.

Place And Duration Of Study: Umraniye Training and Research Hospital, İstanbul, Turkey, from 2011-2021.

Interhemispheric Transcingulate Sulcus Approach to Deep-Seated Medial Frontal and Parietal Lesions-Fiber Dissection Study With Illustrative Cases.

Background: Surgery for lesions located in the medial frontal and parietal lobes can be quite challenging for neurosurgeons because of morbidities that may arise from damage to critical midline structures or intact neural tissue that need to be crossed to reach the lesion. In our anatomic studies, the cingulate sulcus was observed as an alternative access route for lesions located in medial frontal and parietal lobes.

Objective: To explain the microsurgical anatomy of the medial hemisphere and cingulate sulcus and to demonstrate the interhemispheric transcingulate sulcus approach (ITCSA) with 3 clinical cases.

Comparison of clinical and radiological results of dynamic and rigid instrumentation in degenerative lumbar spinal stenosis.

Objective: Lumbar spinal stenosis is defined as a clinical syndrome characterized by neurogenic claudication or radicular pain due to the narrowing of the spinal canal or neural foramen and the compression of its neural elements. Surgical treatment is applied to decompress the neural structures. In some cases, transpedicular instrumentation and fusion may also be applied.

Surgical Treatment of Spinal Arachnoid Cysts: Cyst Excision or Fenestration?

Aim: Arachnoid cysts in the spinal canal account for 1%-3% of all spinal canal lesions. There is no consensus on surgical treatment yet. Dural defect repair is crucial in surgical treatment patients with an extradural component.

Factors Associated with Nontraumatic Spontaneous Subdural Hematomas in Pediatric Patients.

Objective: In our study, we aimed to summarize the etiology of subdural hematoma that was not traumatic and required operation in pediatric patients. The subdural hematoma characteristics, possible etiologies, and treatment, as well as the patient outcomes, were analyzed.

Methods: A retrospective examination was made of pediatric patients with subdural hematoma who were operated on at Ümraniye Training and Research Hospital.

Can Posterior Midline Approach Provide Adequate Exposure for All Craniovertebral Junction Tumors?

Introduction: The surgical treatment of craniovertebral junction (CVJ) lesions remains a difficult process requiring advanced experience. The aim of this study was to present our experience and the clinical results of a posterior and posterolateral approach used for CVJ lesions in our clinic, and to discuss these in light of current literature.

Methods: Clinical, radiologic, and surgical aspects of 30 patients with CVJ tumors were retrospectively evaluated.

Role of Spinal Instability Neoplastic Score in Management of Spinal Plasmacytoma.

Objective: The decision to perform surgery in cases of spinal plasmacytoma (SP) is controversial. This study aimed to evaluate the reliability of the Spinal Instability Neoplastic Score (SINS) in evaluation of spinal instability in patients with SP.

Methods: Clinical and radiological characteristics of 10 patients with SP were retrospectively evaluated.

Acute Neurologic Deterioration in Mobile Spinal Schwannoma.

Background: Spinal schwannomas are commonly presented with minor symptoms, including radicular pain, sensory deficits, and minor neurologic deficit. Acute neurologic deterioration is uncommon.

Case Description: In this study, a case of cauda equina schwannoma presented with acute neurologic deficit after movement of spinal schwannoma is presented.

Nontraumatic Myositis Ossificans as an Uncommon Cause of Scoliosis: Case Report and Review of the Literature.

Background: A 5-year-old pediatric patient developed scoliosis associated with nontraumatic myositis ossificans in the lumbar region. Although there have been reports in literature of syndromes leading to widespread muscle ossifications resulting in shoulder deformities owing to impaired movement in the facet joints, to the best of our knowledge there has been no report of scoliosis associated with myositis ossificans.

Case Description: The case presented is of a 5-year-old girl who developed scoliosis associated with nontraumatic myositis ossificans in the lumbar region.
