Simple, fast detection of cerebrospinal fluid leakage due to head injuries is important for diagnosis and early start-up of correct treatment. We are not aware of any good, rapid diagnostic tests for detecting cerebrospinal fluid. Measuring sugar concentration and protein content normally yields uncertain results. At the University Hospital of North Norway in Tromsø, tinted chlorhexidine has be...

STUDY DESIGN This was a retrospective study of patients who had developed a dural tear after thoracic and lumbar spine surgery that was not recognized during the surgery, and was treated either by lumbar drainage or over-sewing of the wounds. PURPOSE To revisit the treatment strategies in postoperative dural leaks and present our experience with over-sewing of the wound and lumbar drainage. ...

We report three patients with spontaneous intracranial hypotension in whom spinal MR imaging revealed ventral extradural fluid collections that were centered at the cervicothoracic junction in two patients and extended throughout the entire spine in the third patient. These spinal fluid collections most likely resulted from the accumulation of CSF at the site of dural leakage. Knowledge of this...

STUDY DESIGN Cross sectional study. PURPOSE The purpose of this study was to determine the incidence and the associated risk factors of pinhole type of durotomy and cerebrospinal fluid (CSF) leakage following a simple laminectomy for spinal stenosis. OVERVIEW OF LITERATURE The incidence of spinal stenosis is expected to rise with increasing life expectancy. Moreover, lumbar spinal stenosis ...

BACKGROUND Post-dural puncture headache (PDPH) due to excessive cerebrospinal fluid (CSF) leakage is a well-known complication of lumbar puncture. Although various factors, especially the type of spinal needle, have been demonstrated to be associated with PDPH, the clinical implications of CSF leakage detected on magnetic resonance myelography (MRM) images remain unclear. The objective of this ...

The failure of wellbore sealing will cause leakage greenhouse gases, such as carbon dioxide and methane, which harm oil gas recovery environmental safety. Cementing is an important part sealing. Only good cementing can keep the seal for a long time improve well life. In this study, we considered construction horizontal shale in eastern China background analysed rheological properties annulus fl...
