Antiplatelet therapy is mandatory for prevention of thrombotic events in patients with a recent history of acute coronary syndromes and/or percutaneous coronary interventions. However, if an urgent surgery is required during antiplatelet therapy, a compromise between the ischemic/thrombotic and hemorrhagic risk has to be reached. Different bridging schemes are reported in the literature, but there is no clear consensus on the optimal treatment strategy in terms of efficacy and safety. Although some indications about the perioperative management of antiplatelet therapy regarding specific surgical specializations are available, balancing the thrombotic and hemorrhagic risk on an individual basis, no evidence referring to neurosurgical or neuro-oncologic procedures is reported...

BACKGROUND:  Skull metastases from follicular thyroid carcinoma (FTC) are infrequent but clinically significant, often presenting with localized pain, neurologic deficits, and cranial nerve dysfunction. Early detection and accurate diagnosis pose challenges due to their asymptomatic nature in some cases. METHODS:  A systematic literature review, conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, identified and analyzed 15 relevant studies focusing on large skull metastases in FTC...

BACKGROUND:  Although, cranioplasty is a commonly performed neurosurgical procedure worldwide, the cost of available cranioplasty implants is a major issue in a low-income country like India. The aims of this study were to introduce a novel and low-cost technique using a single standard three-dimensional (3D) skull model to guide the polymethyl methacrylate (PMMA) cranioplasty flap production and to evaluate the functional and cosmetic outcomes. METHODS:  We retrospectively evaluated 47 cases of PMMA cranioplasty in the period from February 2019 to June 2022...

BACKGROUND:  Quality of life (QoL) may be affected due to various reasons such as low back or leg pains with accompanying neurologic problems. Lumbar disk surgery is one of the most common performed surgeries to relieve those symptoms. Various anesthetic techniques can be used safely to perform lumbar disk surgeries. Properties that make an anesthetic technique good are mainly the quick onset and returning of the effects. This large retrospective study with patients who have undergone lumbar disk surgery under spinal anesthesia aims to evaluate the perioperative and postoperative parameters of the spinal anesthesia and review the literature...

BACKGROUND AND OBJECTIVE: Stereo-electroencephalography (SEEG) electrodes are implanted using a variety of stereotactic technologies to treat refractory epilepsy. The value of SINO-robot for SEEG electrode implantation is rarely reported. The aim of the current study was to assess the value of SINO-robot in conjunction with Angio Render technology, in SEEG electrode implantation. We also assess its efficacy by examining factors such as localization error, operation time, and complications...

BACKGROUND: The present study aimed to compare the clinical and radiological outcomes of oblique lumbar interbody fusion (OLIF) combined with lateral screw fixation and minimally invasive transforaminal lumbar interbody fusion (Mis-TLIF) for the treatment of single-level degenerative lumbar spondylolisthesis (DLS). METHODS: Data regarding clinical and radiological outcomes for single-level DLS treated using OLIF combined with lateral screw fixation or Mis-TLIF between November 2017 and June 2020 were retrospectively analyzed...

BACKGROUND:  This study investigates the correlation of the radiologic sign of interhemispheric subdural hematoma (iSDH) in different injury patterns with clinical coagulation disorders. It is hypothesized that the presence of iSDHs is correlated with clinical coagulation disorders in patients with traumatic brain injuries and subdural hematoma (SDH). METHODS:  Between January 1, 2020 and June 30, 2022, 154 patients with SDH were identified. Coagulation disorders were assessed using chart review and patients were divided into four groups: SDH without iSDH without further injuries (SDH), SDH with iSDH without further injuries (SDH + iSDH), SDH without iSDH with further brain injuries (Combi), SDH with iSDH with further injuries (Combi + iSDH)...

BACKGROUND:  A neurovascular conflict (NVC) is considered the cause of trigeminal neuralgia (TN) in 75% of cases, and if so, a microvascular decompression (MVD) can lead to significant pain relief. A reliable preoperative detection of NVC is essential for clinical decision-making and surgical planning, making detailed neuroradiologic imaging an important component. We present our experiences and clinical outcomes with preoperative planning of the MVD procedure in a virtual reality (VR) environment, based on magnetic resonance imaging (MRI) including magnetic resonance angiography (MRA) and magnetic resonance venography (MRV) sequences...

PURPOSE: To evaluate changes in radiological parameters and clinical outcomes following unilateral biportal endoscopic unilateral laminotomy bilateral decompression for treatment of central lumbar spinal stenosis. METHODS: Forty-one central lumbar spinal stenosis patients who underwent unilateral biportal endoscopic unilateral laminotomy bilateral decompression (UBE ULBD) were enrolled from April 2021 to February 2023. Visual analog scale (VAS) back pain, VAS leg pain, Oswestry Disability Index (ODI) score and the modified MacNab criteria were assessed preoperatively, postoperatively...

BACKGROUND:  Subdural hematoma (SDH) occasionally accompanies dural metastasis and is associated with high recurrence rate, significantly impacting patient morbidity and mortality. This systematic review aims to evaluate the characteristics, management options, and outcomes of patients with SDH associated with dural metastasis. METHODS:  A comprehensive search of the PubMed and Cochrane databases was conducted for English-language studies published from inception to March 20, 2023, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

BACKGROUND:  Gamma Knife radiosurgery (GKRS) has been demonstrated to be an effective and safe treatment method for dural arteriovenous fistulas (DAVFs). However, only few studies, mostly with limited patient numbers, have evaluated radiosurgery as a sole and upfront treatment option for DAVFs. METHODS:  Thirty-three DAVF patients treated with GKRS as a stand-alone management at our institution between January 1992 and January 2020 were included in this study...

OBJECTIVE We analyzed clinical and radiographic outcomes in patients undergoing anterior lumbar interbody fusions (ALIFs) using a new biomimetic titanium fusion cage (Titan nanoLOCK interbody, Medtronic, Minneapolis, Minnesota). This specialized cage employs precise nanotechnology to stimulate inherent biochemical and cellular osteogenic reactions to the implant, aiming to amplify the rate of fusion. To our knowledge, this is the only study to assess early clinical and radiographic results in ALIFs. METHODS We conducted a retrospective review of data for patients who underwent single or multilevel ALIF using this implant between October 2016 and April 2021...

BACKGROUND: Cerebral vasospasm, a serious complication of subarachnoid hemorrhage (SAH), has been extensively studied for its neurochemical and pathophysiological mechanisms. However, the contribution of inner elastic membrane dissection and subintimal hemorrhage to basilar artery occlusion remains underexplored. This study investigates inner elastic membrane-related changes in the basilar artery after SAH. METHODS: Twenty-four hybrid rabbits were divided into control, sham, and SAH groups, with SAH induced by autologous blood injection...

Background The event of extradural hematoma in the absence of head trauma is a rare central nervous system complication of sickle cell disease. We report here a case of spontaneous extradural hematoma in a patient being treated for sickle cell vaso-occlusive crisis complicated by hyperinflammation and thrombotic microangiopathy. The significance of inflammation as an integral component of the pathomechanism of vaso-occlusive crisis in patients with sickle cell disease and the role of heme in activating the complement system's alternative pathway are highlighted in this case report...

Treatment of vertebral artery aneurysms can be challenging due to the unusual vascular anatomy or unfeasibility of traditional endovascular techniques. We describe a novel approach for endovascular treatment of a ruptured intracranial vertebral artery aneurysm with bilateral vertebral artery occlusions and hypoplasia of the posterior communicating arteries. Successful coil embolization was performed using a collateral pathway for microcatheterization via anastomosis between the deep cervical artery and the vertebral artery...

BACKGROUND: In pediatrics, shunt infection is considered the most common complication of ventriculoperitoneal (VP) shunts insertion and the main cause of shunt failure. Careful surgical technique and hygienic skin preparations are highly important for prevention of shunt infections. Our objective was to assess the significance of using preoperative chlorhexidine/alcohol as a skin antiseptic in reducing the infection rate in pediatric VP shunts surgery. PATIENTS AND METHODS: A retrospective, case control study conducted on 80 pediatric patients with active hydrocephalus...

BACKGROUND:  Multiple hippocampal transection (MHT) is a surgical technique used for the treatment of drug-resistant mesial temporal lobe epilepsy in situations where standard procedures would pose a high risk for memory deterioration. During MHT, the longitudinal fibers of the hippocampus, implicated in epilepsy spreading, are interrupted, while the transverse memory circuits are spared. The extent of MHT is governed by intraoperative electrocorticography; abolition of epileptic discharges serves as an end point to terminate the transection...
