The EVICEL® Neurosurgery Phase III Study
Cerebrospinal Fluid LeakThe objective of this study is to evaluate the safety and efficacy of EVICEL® Fibrin Sealant (Human) for use as an adjunct to sutured dural repair in cranial surgery.
Acetazolamide for the Prevention of Post Operative CSF Leak
Cerebrospinal Fluid LeakThe purpose of this research is to test the use of Acetazolamide in preventing post-operative cerebrospinal fluid leak in patients having endoscopic skull base surgery (it is a surgery performed through the nose and sinus).
The Efficacy and Safety of a Latest Dural Substitute
Cerebrospinal Fluid LeakThis prospective, multi-center, randomized, parallel-controlled clinical trial was designed to evaluate the efficacy and safety of Lyoplant Onlay in repairing cerebral dura mater. DURAFORM was regarded as the control group. a total of 80 patients were randomized into experimental and control group (1:1).Data were collected on complications resulting in CSF leaks, surgical site infections, instrument performance parameterized other neurological complications within 30 days. Surgeons also provided data on the ease of use of the dural sealing techniques, as well as preparation and application times. The above-mentioned date were used to evaluate the efficacy and safety of Lyoplant Onlay .
Mobilisation Algorithm After Incidental Durotomy
Cerebrospinal Fluid LeakPatients with persistent symptoms of cerebrospinal-fluid leakage (positional headache, photophobia, nausea and vomiting, clear drainage from the wound, fluctuant subcutaneous wound) after a primary repair should be considered for revision surgery to avoid potentially serious complications including CSF (cerebro spinal fluid) fistula formation. Prolonged bed rest immediatel after reapir of an ID () incidental durotomy) is widely accepted and frequently applied. current literature provides supporting retrospective evidence that prolonged bed rest may not be required after watertight closure of dural tears. The purpose of this study is to further investigate the impact of prolonged bed rest on the need for early reoperation following primary repair of an ID after lumbar spinal surgery. The primary endpoint of this study is the difference in reoperation rate between the two study groups to further investigate if either one or the other postoperative mobilisation regimen provides a significant benefit in terms of persistent dural leakage.
The Effect of an ASC-seeded Collagen Hydrogel on Cerebrospinal Fluid Leak Rates Following Skull...
CSF LeakThis project seeks to test whether a cell-seeded collagen hydrogel dressing can reduce CSF leak after skull base surgery. Normally, patients at risk for CSF leak are treated with a commercial collagen matrix called Duragen. In this study, our sterile, cGMP manufactured collagen hydrogel dressing will be seeded with the stromal vascular fraction (SVF) mechanically isolated from lipoaspirate taken intra-operatively. This SVF contains pro-regenerative adipose stem cells (ASCs). The ASC-seeded hydrogel will be used as a supplement to Duragen to reinforce the skull base closure. The goal is to establish safety as well as to secondarily evaluate for effectiveness in reducing CSF leak postoperatively.
Free Middle Turbinate Flap for Repair of Low Flow Cerebrospinal Fluid Leak
CSF LeakageLimited literature has been reported the use of free middle turbinate flap during an endoscopic approach to treat cerebrospinal fluid (CSF) leak, and the results were inconclusive. The overall purpose of this study was to assess the efficacy and safety of free middle turbinate flap in reparing CSF leak during an endoscopic approach.
Evaluation of a Simulation Based Workshop in an Anesthesia Residency Program
Cerebrospinal Fluid Drainage CatheterThe study aim is to determine whether simulation based learning would improve senior anesthesiology residents' patient care performance during the insertion and management of cerebrospinal fluid drainage catheters when compared to interactive problem based learning (PBL) using the Anesthetist's Nontechnical Skills Global rating scale
Value of Radionuclide Cisternography
CSF LeakFistulaRadionuclide cisternography (RC) is a nuclear medicine examination based on intrathecal injection of [111In]diethylenetriaminepentaacetic acid ([111In]DTPA). It is prescribed for two recommendations: detection of cerebrospinal fluid (CSF) leak/fistula and diagnosis of normal pressure hydrocephalus. In the search part of CSF leak/fistula, RC offers the benefit of a 24-hour study of CSF unlike other reference tests. In addition to SPECT/CT imaging, the radiopharmacist performs sampling in nasal cavities and throat of the patient to collect a possible flow of CSF. These samples are analysed by radioactivity measurements and bring an added value to the exam. The interest of this examination for management of CSF leak/fistula remains unclear. The aim of this study is to identify and analyse results of all RC examinations performed since 2005 in the Nuclear Medicine department of the Neurological Hospital. The full analysis of patients will allow discussing the role of RC in management of CSF leak/fistulae in clinical practice.
Cerebrospinal Fluid Rhinorrhea After Functional Endoscopic Sinus Surgery
Cerebrospinal Fluid LeakageSinus surgery is a common procedure. A potential complication is injuring the membranes of the brain. This can lead to leakage of brain fluid through the nose. We would like to estimate the incident rates of that complication. At the end of the operation, a thin gauze is inserted into the nose on both sides in addition to the usual tampon. This gauze will be analyzed at the laboratory for beta-2-transferrin, which is a biomarker for brain liquid.
Perioperative CSF Leak Management - an Opinion Study
Cerebrospinal Fluid LeakCerebrospinal fluid (CSF) leak is a rare condition. When it involves the ventral skull base, a surgical closure may be achieved using endoscopic skull base surgery techniques. The major principles remain in achieving a watertight closure that can also support the brain (and avoid brain sagging) in case of extensive skull base defects. Surgical techniques are well described. Many clinical factors may influence the successful rate of the reconstruction. However, there is a lack of clinical study on perioperative management of CSF leaks. The purpose of this study is to gather the opinion of skull base surgeons on the post-operative management of patients to avoid CSF leak recurrence. •Methods: The investigators will collect data from skull base surgeons using an electronic survey questionnaire (Google Form, Google, Mountain View, California, U.S.A.) submitted by e-mail to the members of the French Association of Rhinology, to the European Rhinologic Society, to the French college of neurosurgeons, to the Italian skull base society members, and to the former students of the European endoscopic skull base diploma. This is an anonymous 60-items survey. Questions were classified in eight sections: general questions, material used at the end of the surgical procedure, post-operative resting position, drugs, CSF depletion, post-operative advices, explorations in case of early recurrence of the rhinorrhoea, and follow-up modalities. •Discussion: The investigators aim to understand the actual practice of skull base surgeons after closure of ventral skull base CSF leaks. This can serve as a basis for conducting clinical studies in the future.
