BACKGROUND: Cerebrospinal fluid (CSF) leakage occurs in 4% to 32% of cranial surgeries and is associated with significant patient burden and expense. The use of sealant as an adjunct to primary dural closure is assumed to help prevent CSF leakage. OBJECTIVE: To examine the utility of different sealants for dural closure using an in Vitro model. METHODS: We evaluated 9 commonly used dural sealants, including Tachosil (Takeda Inc, Osaka, Japan), Adherus (Hyperbranch Inc, Durham, North Carolina), Duraform (Codman, Raynham, Massachusetts), Tissudura (Baxter, Deerfield, Illinois), Hemopatch (Baxter), TissuePatchDural (Tissuemed, Leeds, United Kingdom), Tisseel (Baxter), Duragen Secure (Integra, Plainsboro, New Jersey), and Duraseal, (Integra)...

Endoscopic endonasal surgery, an innovative surgical technique, is used to approach sinus lesions, lesions of the skull base, and intradural tumors. The cooperation of experienced otolaryngologists and neurosurgeons is important to achieve safe and reliable surgical results. The bath plug closure method is a treatment option for patients with cerebrospinal fluid(CSF)leakage. Although it includes dural and/or intradural procedures, surgery tends to be performed by otolaryngologists because its indications, detailed maneuvers, and pitfalls are not well recognized by neurosurgeons...

When a dural defect is encountered during spine surgery, the dura mater must be reconstituted to minimize the occurrence of minor or major life-threatening sequelae. The neurosurgical literature lacks strategies for managing large dural defects encountered during surgery. The authors describe a 24-year-old man who developed cauda equina syndrome secondary to altered CSF flow in a large thoracolumbar arachnoid cyst. Surgical decompression and fenestration of the arachnoid cyst were performed, and the large dural defect was treated using a multilayer closure with collagen matrix, titanium mesh, and methylmethacrylate...

Background: Dural arteriovenous fistulas (DAVF) are unusual intracranial vascular malformations consisting of anomalous connections between meningeal arteries and dural sinuses or the veins that pass through them. They have variable clinical presentation and prognosis, which depend on their location and venous hemodynamics. Treatment is based on the closure of the abnormal connections, which is usually conducted via arterial and/or transvenous endovascular techniques. Case Description: We present a male patient who complained of headaches and left-sided pulsatile tinnitus due to DAVF from the external carotid artery branches draining directly into the ipsilateral sigmoid sinus...

Postoperative continuous bloody cerebral spinal fluid (CSF) drainage with external ventricular drainage catheter could decrease the incidence of inflammation. But the drainage catheter left in place will interrupt the watertight dura matter closure. To prevent the related CSF leakage and subgaleal pseudomeningocele after the catheter removal, we developed a patched closure method to seal the dural outlet of the drainage catheter with a favorable clinical outcome.

BioGlue® is an inert, bioadhesive surgical substance commonly used in spinal surgery to aid dural closure. The authors describe two cases in which the use of BioGlue® caused a local reaction culminating in the formation of a granuloma that caused cord compression several years after surgery in one case in which a second operation was required to relieve cord compression and remove the foreign material. In the other case spontaneous resolution occurred. To our knowledge these are the first reports of delayed spinal cord compression secondary to BioGlue®-induced granuloma...

Cranioplasty is a comparatively simple neurosurgical procedure, and fatal complications are rare. This report describes two cases of critical brain swelling after otherwise uneventful cranioplasty. Both cases had subarachnoid hemorrhage and extremely similar clinical courses. They underwent decompressive craniotomy and clipping in the acute phase and had cranioplasty in the chronic phase, resulting in serious cerebral swelling and death. Deep venous sinus thrombosis was revealed in the autopsy for one case...

BACKGROUND: Dural repair in areas with limited operative maneuverability has long been a challenge in skull base surgery. Without adequate dural closure, postoperative complications, including cerebrospinal fluid (CSF) leak and infection, can occur. METHODS: We reviewed 53 consecutive surgical patients in whom a dural repair technique utilizing titanium microclips was performed from 2013 to 2016 at our institution. The repairs primarily involved difficult-to-reach dural defects in which primary suturing was difficult or impractical...

BACKGROUND: Treatment of thoracic spinal dural arteriovenous fistulas (DAVFs) by microsurgery has recently been approached using minimally invasive spine surgery (MISS). The advantages of such an approach are offset by difficult maneuverability within the tubular retractor and by the creation of "tunnel vision" with reduced luminosity to a remote surgical target. OBJECTIVE: To demonstrate how the pitfalls of MISS can be addressed by applying 3-D endoscopy to the minimally invasive approach of spinal DAVFs...

BACKGROUND: Pseudomeningocele, an extradural collection of cerebrospinal fluid (CSF), has only been rarely reported to occur spontaneously in conjunction with isthmic spondylolisthesis (with lysis) in the lumbar spine. CASE DESCRIPTION: A 68-year-old male presented with low back pain and neurogenic claudication of several years duration without any history of trauma, epidural spine injections, or spine surgery. Lumbosacral magnetic resonance imaging (MRI) revealed a grade-I L4-L5 isthmic spondylolisthesis with spinal canal narrowing and a posterior paravertebral collection consistent with CSF...

When a wide polygonal dural window is created, a short dural incision length is preferred by surgeons because suturing a wastefully long incision line during closure is troublesome. A locator to facilitate making the shortest dural incision when creating a polygonal dural window would be helpful. We geometrically analyzed the shortest incision design for a pentagonal dural window and produced a simple locator for intraoperatively implementing this design. The design for a pentagonal dural window with the shortest incision is the same as the design for a minimum Steiner tree (MST) problem with five vertices...

This is a case report of a 60-year-old male admitted on suspicion of relapse of idiopathic transverse myelitis (TM), who after further diagnostic workup underwent successful closure of a dural arteriovenous fistula (DAVF). Magnetic resonance imaging in DAVF usually shows longitudinal TM, which, unlike DAVF, is also seen with the more common inflammatory or infectious causes usually showing inflammation in the cerebrospinal fluid. The natural history of DAVF is progressive. Since curable options exist, timely diagnosis is most important...

INTRODUCTION: Development of a posttraumatic herniation of brain parenchyma through the orbit is a rare complication of orbital roof fracture. Mostly, the injury is due to a direct impact to the frontal region resulting in orbital roof fracture with dural defect and herniation of cerebrospinal fluid or brain parenchyma. These patients present with acute or gradually progressive proptosis with impending risk of loss of vision and mandate surgical decompression of optic nerve with watertight closure of the dural defect...

BACKGROUND: The presence of skull fracture in patients sustaining traumatic brain injury is an important risk factor for intracranial lesions. Assessment of integrity of dura in depressed skull fracture is of paramount importance because if dura is torn, lacerated brain matter may be present in the wound which needs proper debridement followed by water tight dural closure to prevent meningitis, cerebral abscess, and pseudomeningocoele formation. The objective of this study was to determine the frequency of dural tear in patients with depressed skull fractures...

Patients with penetrating head trauma with retained projectiles develop intracranial abscesses as a common complication. The most common presentation is a suddenly worsening headache. The most common pathogen identified is staphylococcus. Outcomes are related to adherence of Matson's tenets. This case study details the presentation of a 19-year-old patient that presented to the neurological surgery clinic without neurologic deficits. Further questioning revealed complaints of intermittent diffuse headaches with bilateral upper extremity shock-like sensation for two weeks...
