BACKGROUND: Despite clinical reports of poor outcomes, the degree to which resuscitative endovascular balloon occlusion of the aorta (REBOA) exacerbates traumatic brain injury (TBI) is not known. We hypothesized that combined effects of increased proximal mean arterial pressure (pMAP), carotid blood flow (Qcarotid), and intracranial pressure (ICP) from REBOA would lead to TBI progression compared with partial aortic occlusion (PAO) or no intervention. METHODS: Twenty-one swine underwent a standardized TBI via computer Controlled cortical impact followed by 25% total blood volume rapid hemorrhage...

STUDY DESIGN: A retrospective review. OBJECTIVES: To evaluate the therapeutic efficacy of the triple layer closure technique to establish watertight sealing without diversion of lumbar drainage, in preventing persistent incidental subarachnoid-pleural fistula and other neurological complications related to excessive drainage of cerebrospinal fluid (CSF) after dural defect in transthoracic ossified posterior longitudinal ligament (OPLL) surgery. SUMMARY OF BACKGROUND DATA: CSF leakage into the pleural cavity leads to unfavorable conditions for natural healing of incidental durotomy due to the negative pressure environment of the pleural space and lack of wound healing around the bony cavity near the decompressed spinal cord...

BACKGROUND: Intracranial hypotension (IH) is a recognised cause of coma, however, the diagnosis is often challenging, especially in patients with superimposed traumatic brain injury (TBI). CASE REPORT: We report a case of a 67-year-old patient who became comatose following evacuation of bilateral acute subdural haematomas with concurrent respiratory failure. Imaging and intraparenchymal intracranial pressure (ICP) monitoring confirmed secondary IH. She was managed with an epidural blood patch, and a 72 hours period in the trendelenberg position guided by ICP monitoring and clinical assessment...

Cerebral venous thrombosis is a rare complication of intracranial hypotension. We describe 3 cases in which this phenomenon occurred, as a result of a lumbar puncture or due to a spontaneous cerebrospinal fluid leak. We emphasize the importance of early detection of the intracranial hypotension syndrome, the most common clinical manifestation being orthostatic headache. It is not an innocent condition as it is associated with other potential complications such as subdural hygroma/hematoma, cranial nerve palsies, cerebellar tonsillar descent, and even brainstem manifestations...

OBJECTIVE Spinal CSF leakage causes spontaneous intracranial hypotension (SIH). The aim of this study was to characterize CSF dynamics via lumbar infusion testing in patients with and without proven spinal CSF leakage in order to explore possible discriminators for the presence of an open CSF leak. METHODS This analysis included all patients with suspected SIH who were treated at the authors' institution between January 2012 and February 2015. The gold standard for "proven" CSF leakage is considered to be extrathecal contrast accumulation after intrathecal contrast injection...

BACKGROUND: Various types of lumbar dural punctures may contribute to neurological injury. The etiologies of dural injury include; inadvertent dural punctures due to epidurals placed for labor anesthesia, epidural steroid injections (ESI/transforaminal TESI; approximately 9 million ESI performed in the US per year), deliberate placement of intradural pain devices, and spontaneous cerebrospinal fluid (CSF) fistulas. Resulting neurological complications may include; spinal headaches/intracranial hypotension, subdural hematomas, and 6(th) nerve cranial palsies...

Patients with a spontaneous cerebrospinal fluid leak, normally at a spinal level, typically present with low-pressure headache. In refractory cases, an epidural blood patch may be attempted. We aimed to assess the efficacy of lumbar epidural blood patching in spontaneous, low-pressure headaches. Methods We retrospectively analysed notes of patients who had an epidural blood patch performed for spontaneous low-pressure headaches in a single centre. Information regarding demographics, radiology and clinic follow-up was extracted from an electronic patient record system...

Management of giant intracranial aneurysms presents unique challenges to the neurosurgical team. Various techniques such as adenosine-induced hypotension, rapid ventricular pacing, and inducing deep hypothermia are described in the literature to effect circulatory arrest for the successful obliteration of giant aneurysms. We describe a novel technique of induced hypotension for clipping a giant aneurysm by using an inflatable balloon across the main pulmonary artery with a successful outcome. This technique has not been described earlier in the literature...

BACKGROUND: Clinical presentation of spontaneous intracranial hypotension headache (SIHH) has similarities with postdural puncture headache (PDPH). Recommended treatment for both conditions is an epidural blood patch. Successful outcomes following greater occipital nerve blocks have been reported in the management of PDPH. We present the first report of greater occipital nerve treatment in SIHH. METHODS: A 40-year-old male presented with a 2-year history of daily postural headaches having a significant impact on quality of life...

A 47-year-old man presented with a 9-year history of a hypoalert hypoactive behaviour syndrome, caused by the deep brain swelling variant of spontaneous intracranial hypotension. Along with apathy with retained cognition, he had stable ataxia, impaired upgaze and episodes of central apnoea. MRI brain showed a sagging brainstem, pointed ventricles and reduced angle between the vein of Galen and the straight sinus, but no meningeal enhancement or subdural collections. A dopamine transporter scan showed preganglionic dopamine receptor deficiency; a fluorodeoxy glucose positron emission tomography scan showed bilateral hypothalamic hypometabolism...

OBJECTIVE: To evaluate the imaging characteristics and diagnostic utility of the "Dinosaur tail sign" in the diagnosis of cerebrospinal fluid (CSF) leakage. BACKGROUND: The authors propose the "Dinosaur tail sign," defined as a combination of the dorsal epidural hyperintensities, fat tissue, spinal cord, and cauda equine on lumbosacral sagittal fat-suppressed T2-weighted image (FST2WI), as a sensitive indicator for diagnosing CSF leakage. METHODS: Imaging characteristics of the "Dinosaur tail sign" was evaluated in seven spontaneous intracranial hypotension (SIH) and 23 iatrogenic CSF leakage (ICSFL) patients...

CONTEXT: Ventral longitudinal intraspinal fluid collection (VLISFC) presenting as hand amyotrophy has been described only in a few cases and there are no reports on associated intracranial CSF hypovolemia (ICH). We describe the clinical and imaging findings of a case with combined brachial amyotrophy and ICH secondary to VLISFC. FINDINGS: A 31 year old man presented with severe positional neck discomfort, radiating pain, progressive asymmetrical wasting and weakness of distal upper limbs...

Wittstatt Alexandra Whitaker-Lea, Alex B Valadka
Traumatic brain injury (TBI) continues to be a major public health problem. Proposed treatments have not withstood testing in clinical trials because of failure to account for different types of TBI and other weaknesses in trial design. Management goals continue to be prevention and prompt treatment of secondary insults (hypotension, hypoxia, and other physiologic derangements). This goal is best accomplished by careful attention to airway, breathing, circulation, and basic principles of intensive care unit management...

BACKGROUND AND PURPOSE: CSF hypovolemia is a core feature of spontaneous intracranial hypotension. Spontaneous intracranial hypotension is characterized by orthostatic headache and radiologic manifestations, including CSF along the neural sleeves, diffuse pachymeningeal enhancement, and/or venous engorgement. However, these characteristics are only qualitative. Quantifying intraspinal CSF volumes could improve spontaneous intracranial hypotension diagnosis and evaluation of hypovolemic statuses in patients with spontaneous intracranial hypotension...

OBJECTIVE: While a significant amount of experience has accumulated for awake procedures for brain tumor, epilepsy and carotid surgery, its utility for intracranial neurovascular indications remains largely undefined. Awake surgery, for select neurovascular cases, offers the advantage of precise brain mapping and robust neurological monitoring during surgery for lesions in eloquent areas, avoidance of potential hemodynamic instability, and possible faster recovery. Additionally, it opens the window for perilesional epileptogenic tissue resection with potentially less risk for iatrogenic injury...

Spontaneous intracranial hypotension (SIH) is classified as a decrease in cerebrospinal fluid (CSF) pressure secondary to a CSF leakage and consequent descent of the brain into the foramen magnum. Diagnosing SIH can be difficult due to its overlapping findings with Arnold-Chiari type 1 Malformation (CM1) where the cerebellar tonsils herniate into the foramen magnum. The similarity of both conditions calls for a more reliable imaging technique to localize the CSF leak which could narrow the differential diagnosis and aid in choosing the correct treatment...
