Cerebral aneurysms in complex anatomical locations and intraoperative rupture of aneurysms are challenging for neurosurgeons and anaesthetists alike. Mechanical and non-mechanical methods to reduce blood flow into aneurysms are well-recognised techniques to facilitate aneurysm exclusion from the circulation. Mechanical methods like temporary clipping of parent arteries, carotid artery ligation and endovascular balloon occlusion are commonly used in clinical practice. However, non-mechanical techniques such as rapid ventricular pacing and adenosine-induced cardiac standstill with hypotension are still emerging strategies...

Existing literature suggests that use of telemedicine during postoperative appointments can increase access to care and is valued by patients and providers alike. While research examining the clinical equivalency of telemedicine visits for postoperative care has been growing, few studies have reported on telemedicine follow-up after neurosurgery. This study examined if a videoconferencing visit could substitute for an in-person clinic visit for elective neurosurgical cases in the USA. This was a single-center prospective study of patients who underwent elective neurosurgical procedures (aneurysm clipping, resection of cavernous angiomas, resection of arterial venous malformation, microvascular decompression for trigeminal neuralgia and hemifacial spasm, and certain benign brain tumors) and were offered telemedicine follow-up care by an allied health professional during the first 90 days after neurosurgery...

Postoperative wound healing can pose a problem in patients undergoing instrumented surgery for pyogenic spondylodiscitis. Robotic guidance allows the minimally invasive placement of pedicle screws in the thoracolumbar spine. We assessed whether using this technique to perform minimally invasive surgery had an impact on wound healing in patients with pyogenic spondylodiscitis when compared to conventional open fluoroscopy-guided surgery. We reviewed charts of 206 consecutive patients who underwent instrumentation for pyogenic spondylodiscitis...

The aim of this study was to estimate the incidence, identify the causes, and explore treatments of the injuries to the brachial plexus and peripheral nerves of the shoulder girdle and upper limb in the 1,220,000-inhabitant Italian region Friuli Venezia Giulia.We linked at the individual patient level various administrative databases using an anonymous stochastic key: list of residents, hospital discharge, emergency department, and outpatient care prescriptions database. We abstracted hospital discharge records with at least one discharge diagnosis code ICD-9-CM 953...

Intramedullary spinal cord tumors (IMSCTs) are relatively infrequent lesions with ependymomas and astrocytomas representing the most common types. Microsurgical resection is established as the treatment of choice for these challenging lesions. We reviewed the surgical outcome of 29 cases operated for IMSCTs by the same surgeon between 2009 and 2015. The median follow-up period was 31 months, and all patients were followed up at least for 1 year. Among these 29 cases, 5 patients were previously operated for partial resection elsewhere...

Post-radiotherapy carotid blowout syndrome (CBS) of the skull base is a rare but often catastrophic complication of head and neck malignancies. The existing literature on the treatment of this condition with flow-diverting devices (FDD) is extremely limited and disappointing. We present a case of impending CBS in a patient previously irradiated for nasopharyngeal cancer that was successfully treated with use of multiple FDDs, adjunctive endonasal packing and delayed reinforcement with pedicled naso-septal flap, yielding an excellent outcome at 14-months follow-up...

REVIEW
Martin Májovský, David Netuka, Vladimír Beneš
In this short review, the authors performed a database search and summarize current knowledge of the management of patients with pineal cysts (PCs) and investigate the role of surgical treatment. The scientific literature on the surgical treatment of PCs is sparse and encompasses only case series with little over 200 operated patients combined. All included papers reported favorable results after pineal cyst surgery with improvement of symptoms in most patients. Microsurgical resection of PCs, preferably using the supracerebellar-infratentorial approach, could be considered as a viable treatment option in symptomatic patients...

Acute intracranial subdural hematoma (ASDH) is commonly associated with a grave prognosis citing a high incidence of morbidity and mortality. The parameters to decide on surgical evacuation of the hematoma are sometimes controversial. In this study, we theorized that the ratio between maximal hematoma thickness and midline shift would be varied by associated intrinsic brain pathology emanating from the trauma and would thus objectively evaluates the prognosis in ASDH. The records of patients diagnosed with ASDH who were submitted to surgical evacuation through a craniotomy were revised...

The risk of developing a de novo shunt-dependent hydrocephalus (HC) after undergoing a craniotomy for brain tumor in adult patients is largely unknown. All craniotomies for intracranial tumors at Oslo University Hospital in adult patients ≥18 years of age during a 10-year period (2004-2013) were included. None were lost to follow-up. Patients who developed a shunt-dependent HC were identified by cross-linking our prospectively collected tumor database to patients with a NCSP surgical procedure code of hydrocephalus (AAF)...

Extreme long-term clinical outcome studies following anterior cervical discectomy and fusion (ACDF) with an autologous iliac crest with and without Caspar plating (ACDF + CP) for the treatment of radiculopathy caused by cervical disc herniation (CDH) are extremely rare. Hospital records of patients who underwent ACDF or ACDF + CP for the treatment of CDH at least 17 years ago were reviewed. Information about diagnosis, surgery, pre- and postoperative clinical process, and repeated procedure was analyzed...

REVIEW
Yanfei Shen, Xuping Cheng, Weimin Zhang
Fragility of randomized controlled trials (RCTs) has been evaluated using a novel metric called fragility index (FI), which measures how many events the statistical significance of a dichotomous outcome depends on. This study aimed to evaluate the fragility of RCTs in intracranial hemorrhage. Literature search (PubMed/Embase) identified all RCTs of intracranial hemorrhage since 2006. The overall distribution of FI was evaluated. Subgroup and spearman correlation analyses were made to explore potential factors that may affect FI value...

Hemorrhagic complication is one of the notable surgical complications of the revascularization surgery for moyamoya disease (MMD). Cerebral hyperperfusion (CHP) has been considered as the underlying cause of this complication. It mostly occurs several days after surgery, but the intra-operative hemorrhage immediately after bypass has not been reported previously. A 21-year-old woman presented right thalamic hemorrhage and was diagnosed as having MMD by cerebral angiography. In light of the location of the hemorrhage at the vascular territory of posterior circulation and the manifestation of transient ischemic attack during the follow-up period, she underwent revascularization surgery to prevent future ischemic attack and rebleeding...

Meningioma consistency is a critical factor that influences preoperative planning for surgical resection. Recent studies have investigated the utility of preoperative magnetic resonance elastography (MRE) in predicting meningioma consistency. However, it is unclear whether existing methods are optimal for application to clinical practice. The results and conclusions of these studies are limited by their imaging acquisition methods, such as the use of a single MRE frequency and the use of shear modulus as the final measurement variable, rather than its storage and loss modulus components...

Injury to the lumbosacral (LS) plexus is a well-described complication after lateral retroperitoneal transpsoas approaches to the spine. The prognosis for functional recovery after lumbosacral plexopathy or femoral/obturator neuropathy is unclear. We designed a retrospective case-control study with patients undergoing one-level lateral retroperitoneal transpsoas lumbar interbody fusion (LLIF) between January 2011 and June 2016 to correlate electrodiagnostic assessments (EDX) to physiologic concepts of nerve injury and reinnervation, and attempt to build a timeline for patient evaluation and recovery...

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911...

In view of their age and vascular co-morbidities, people are often taking an antithrombotic drug when diagnosed with chronic subdural haematoma (CSDH). It is unclear whether antithrombotic use at CSDH diagnosis, or resumption afterwards, is associated with recurrent CSDH or vaso-occlusive events. We systematically reviewed the literature for studies reporting CSDH recurrence or vaso-occlusive events after drainage of CSDH associated with antithrombotic drug use. We searched Medline 1946-2016 and Embase 1974-2016 inclusive for cohort studies reporting the risk of CSDH recurrence or vaso-occlusive events after CSDH associated with antithrombotic (anticoagulant or antiplatelet) drug use...

Olfactory neuroblastoma (ONB) is a potentially curable disease, despite being an aggressive malignancy with a poor natural history. Our goal was to evaluate management outcomes for patients with ONB treated at our institution. Our prospective database for brain tumors and the pathology registry of head and neck cancers at Oslo University Hospital were searched to identify all patients treated for ONB between 1998 and 2016. Variables extracted from these databases, supplemented by retrospective chart reviews, underwent thorough analysis...

Chronic subdural hematoma (CSDH) with brain herniation signs is rarely seen in the emergent department. As such, there are few cumulative data to analyze such cases. In this study, we evaluated the clinical features, risk factors, and rates of completion with impending brain herniation on arrival in a cohort study. We analyzed 492 consecutive patients with CSDH between January 2010 and October 2015. First, we analyzed the clinical factors and compared them between patients with or without brain herniation signs on admission...
