INTRODUCTION: Deep vein thrombosis (DVT) continues to be a significant source of morbidity for surgical patients. Placement of a retrievable inferior vena cava (IVC) filter is used when patients have contraindications to anticoagulation or recurrent pulmonary embolism despite therapeutic anticoagulation. Although retrievable IVC filters are often used, they carry a unique set of risks. PRESENTATION OF CASE: A 67-year-old man presents to the Emergency Room (ER) following large volume melena and complaining of syncope...

At present, presurgical functional mapping is the most prevalent clinical application of functional magnetic resonance imaging (fMRI). Signal dropouts and distortions caused by susceptibility effects in the current standard echo planar imaging (EPI)-based fMRI images are well-known problems and pose a major hurdle for the application of fMRI in several brain regions, many of which are related to language mapping in presurgical planning. Such artifacts are particularly problematic in patients with previous surgical resection cavities, craniotomy hardware, hemorrhage, and vascular malformation...

A 68-year-old man presented with intracranial hemorrhage in the right frontal lobe, which rapidly increased the day after admission. We performed hematoma removal with a biopsy of the cortex around the hematoma. The day after the operation, a subcutaneous hematoma over the craniotomy appeared, and the computed tomography showed a recurrent hemorrhage with an acute subdural hematoma. We were aware of a bleeding tendency, and a detailed hematologic examination by hematologists revealed autoimmune acquired factor XIII deficiency due to an antifactor XIII antibody...

OBJECTIVE Temporal lobe encephaloceles and cerebrospinal fluid otorrhea from temporal bone defects that involve the tegmen tympani and mastoideum are generally repaired using middle fossa craniotomy, mastoidectomy, or combined approaches. Standard middle fossa craniotomy exposes patients to dural retraction, which can lead to postoperative neurological complications. Endoscopic and minimally invasive techniques have been used in other surgeries to minimize brain retraction, and so these methods were applied to repair the lateral skull base...

BACKGROUND: Neurosurgical patients are aging as the general population is getting older. METHODS: A retrospective review of patients ≥ 65 years of age who underwent an elective craniotomy from 2007-2015 to identify risk factors for 30-day morbidity/mortality was conducted. Key preoperative variables included age, co-morbidities, and functional status based on the Karnofsky Performance Status (KPS) score and modified Rankin Scale (mRS) score. Outcome variables included long-term care (LTC) complications, neurologic complications, systemic/infectious complications, length of stay (LOS), functional outcomes, and mortality...

BACKGROUND: The frontal aslant tract (FAT) is a deep frontal pathway connecting the superior frontal gyrus (SFG) to Broca's area. This fiber is assumed to be associated with language functions, especially speech initiation and spontaneity. OBJECTIVE: The aim of this study was to electrophysiologically investigate this network using cortico-cortical evoked potentials (CCEPs). METHOD: Eight patients with brain tumors or medically intractable focal epilepsies who underwent frontal craniotomy over the language dominant side were enrolled in this study...

We report a rare case of subarachnoid hemorrhage(SAH)due to ruptured extracranial aneurysm originating at the caudal loop of the left posterior inferior cerebellar artery(PICA). A 50-year-old woman presented with severe headache and mild consciousness disturbance. Computed tomography(CT)revealed SAH and intraventricular hemorrhage. Vertebral angiography showed an extracranial aneurysm located on the tonsillomedullary segment of the left PICA. During the surgery, no vessel branches were confirmed near the aneurysm, and the aneurysm was successfully clipped through suboccipital craniotomy with C1 laminectomy...

BACKGROUND: Chronic subdural hematoma(CSDH)generally occurs in the elderly, and is usually treated by burr-hole craniotomy with closed-system drainage. Treatment of recurrent CSDH is more challenging, especially when the hematoma is multi-lobular. A variety of approaches to the management of multi-lobular CSDH have been described, including evacuation through a wide craniotomy, placement of an Ommaya reservoir, subdural peritoneal shunting, and embolization of the middle meningeal artery...

BACKGROUND: The role of decompressive craniectomy in treating raised intracranial pressure (ICP) after traumatic brain injuries (TBI) is controversial. The aim of this study was to assess the differences in prognosis of patients initially treated by decompressive craniectomy, craniotomy, or conservatively. METHODS: We conducted a single-center retrospective study on adult blunt TBI patients admitted to a neurosurgical intensive care unit during 2009-2012. Patients were divided into three groups based on their initial treatment - decompressive craniectomy, craniotomy, and conservative...

OBJECTIVE The objective of this study was to detect 5-aminolevulinic acid (ALA)-induced tumor fluorescence from glioma below the surface of the surgical field by using red-light illumination. METHODS To overcome the shallow tissue penetration of blue light, which maximally excites the ALA-induced fluorophore protoporphyrin IX (PpIX) but is also strongly absorbed by hemoglobin and oxyhemoglobin, a system was developed to illuminate the surgical field with red light (620-640 nm) matching a secondary, smaller absorption peak of PpIX and detecting the fluorescence emission through a 650-nm longpass filter...

OBJECTIVE The best approach to deep-seated lateral and third ventricle lesions is a function of lesion characteristics, location, and relationship to the ventricles. The authors sought to examine and compare angles of attack and surgical freedom of anterior ipsilateral and contralateral interhemispheric transcallosal approaches to the frontal horn of the lateral ventricle using human cadaveric head dissections. Illustrative clinical experiences with a contralateral interhemispheric transcallosal approach and an anterior interhemispheric transcallosal transchoroidal approach are also related...

Georg C Clarici
CLINICAL ISSUE: In Austria approximately 2000 people suffer from severe brain injury per year. Brain trauma is the most common cause of death under the age of 45 years. In polytrauma patients the treatment and management of severe brain injury is particularly challenging because the life-threatening injuries of other organ systems significantly influence the timing of surgery and the outcome. The sequence of the necessary surgery is an interdisciplinary decision already made in the emergency room...

Patients with obstructive sleep apnea are frequently considered unsuitable candidates for awake craniotomy due to anticipated problems with oxygenation, ventilation, and a potentially difficult airway. At present, only a handful of such accounts exist in the literature. Our report describes the novel use of high-flow nasal oxygen therapy for a patient with moderate obstructive sleep apnea who underwent an awake craniotomy under deep sedation. The intraoperative application of high-flow nasal oxygen therapy achieved satisfactory oxygenation, maintained the partial carbon dioxide pressure within a reasonable range even during periods of deep sedation, permitted responsive patient monitoring during mapping, and provided excellent patient and surgeon satisfaction...
