BACKGROUND: The flow pattern of the cerebrospinal fluid is probably the most important factor related to obstruction of ventricular catheters during the normal treatment of hydrocephalus. To better comprehend the flow pattern, we have carried out a parametric study via numerical models of ventricular catheters. In previous studies, the flow was studied under steady and, recently, in pulsatile boundary conditions by means of computational fluid dynamics (CFD) in three-dimensional catheter models...

OBJECTIVE Initiation of external CSF drainage has been associated with a significant increase in rebleeding probability after aneurysmal subarachnoid hemorrhage (aSAH). However, the implications for acute management are uncertain. The purpose of this study was to evaluate the role of the amount of drained CSF on aneurysmal rebleeding. METHODS Consecutive patients with aSAH were analyzed retrospectively. Radiologically confirmed cases of aneurysmal in-hospital rebleeding were identified and predictor variables for rebleeding were retrieved from hospital records...

Mortality and adverse neurologic sequelae from HIV-associated cryptococcal meningitis (HIV-CM) remains high due to raised intracranial pressure (ICP) complications. Cerebrospinal fluid (CSF) high opening pressure occurs in more than 50% of HIV-CM patients. Repeated lumbar puncture with CSF drainage and external lumbar drainage might be required in the management of these patients. Usually, there is a high grade of uncertainty and the basis for clinical decisions regarding ICP hypertension tends to be from clinical findings (headache, nausea and vomiting), a low Glasgow coma scale score, and/or fundoscopic papilledema...

BACKGROUND AND PURPOSE: Delayed cerebral ischemia (DCI) accounts for a major part of the morbidity and mortality after aneurysmal subarachnoid hemorrhage (SAH). MicroRNAs (miRNAs) are pathophysiologically involved in acute cerebral ischemia. This study compared miRNA profiles in cerebrospinal fluid from neurologically healthy patients, as well as SAH patients with and without subsequent development of DCI. METHODS: In a prospective case-control study of SAH patients treated with external ventricular drainage and neurologically healthy patients, miRNA profiles in cerebrospinal fluid were screened and validated using 2 different high-throughput real-time quantification polymerase chain reaction techniques...

PURPOSE: Anterior approach to the upper thoracic spine is difficult. It is important for spine surgeons to know the indication and the effect of anterior decompression for upper thoracic lesions and also to recognize the complications which are related to the approach with sternotomy. We present two patients for whom we took the sternum-splitting anterior approach for thoracic ossification of the posterior longitudinal ligament (OPLL) following posterior decompression and fusion surgery; the clinical course and surgical outcome are discussed, with particular reference to complication avoidance and also we review the previous literature...

BACKGROUND: Chiari Malformation Type I is a hindbrain abnormality characterized by cerebellar tonsils descent beneath the foramen magnum, frequently associated with symptoms or brainstem compression, impaired cerebrospinal fluid circulation and syringomyelia. Foramen magnum decompression represents the most common way of treatment. Rarely, subdural fluid collection and hydrocephalus represent postoperative adverse events. The treatment of this complication is still debated, and physicians sometimes are faced with the doubt of when undergoing diversion surgery and when more conservative managements...

BACKGROUND AND PURPOSE: External drainage of cerebrospinal fluid (CSF) is a commonly used neurosurgical procedure. Complications of the procedure comprise central nervous system (CNS) bacterial infections, the frequency of which is estimated at around 6-10%. Detection of these infections is ineffective in many cases. The aim of the study was to evaluate the usefulness of a polymerase chain reaction (PCR)-based detection of bacterial 16S rRNA gene (16S rDNA) in the CSF. MATERIAL AND METHODS: The study group consisted of 50 patients...

Primary spontaneous cerebrospinal fluid (CSF) rhinorrhea due to clival defect is an extremely rare presentation and only six cases have been reported in the literature so far(17). We present a unique case of a 64-year-old lady who presented with 2 years history of ongoing CSF rhinorrhea. She had similar episode at the age of 40 and suffered from meningitis. She had MRI, CT cisternogram as well as CT of brain and that showed clival defect with CSF leak into the sphenoid sinus. She underwent trans-sphenoidal repair of the clival defect with concurrent lumbar drain insertion for CSF drainage...

INTRODUCTION: Trisomy 9 is an unusual chromosome abnormality in live-born patients, which is frequently accompanied by functional and structural anomalies of the central nervous system. Among many other alterations, several studies have been published in the English-speaking literature that show an association between chromosome 9 abnormality and pathologies affecting the choroid plexuses. CASE REPORT: We report the case of a 4-month-old male with trisomy 9 mosaicism associated to hydrocephalus secondary to choroid plexus hyperplasia, who was referred due to a clinical picture of intracranial hypertension...

BACKGROUND: Retromastoid craniectomy (RSC) is a cardinal surgical approach used to access the posterior fossa. Hydroxyapetite bone cement (HBC) is frequently employed for cranioplasty in efforts to prevent cerebrospinal fluid (CSF) leak, whilst maintaining low complication rates and good cosmetic satisfaction. The authors aim to determine the safety and effectiveness of HBC for reconstruction RSC used for treatment of various cranial nerves disorders. METHODS: The authors conducted a retrospective one-center two surgeons review of 113 patients who underwent RSC filled with HBC for the treatment of cranial nerve disorders...

Raised intracranial pressure is a hallmark of cryptococcal meningitis and is associated with increased mortality. Continuous drainage of lumbar cerebrospinal fluid is suggested to control intracranial pressure. The complications induced by this treatment have been described. However, nursing care associated with identification and management of complications is less well known. We encountered a patient with human immunodeficiency virus-negative cryptococcal meningitis who developed increasing cerebrospinal fluid pressure, hearing impairment, and limb weakness...

Injury of the aortic isthmus is the second most frequent cause of death in cases of blunt traumatic injury. Conventional open repair is related to significant morbidity and mortality. Thoracic endovascular aortic repair (TEVAR) has increasing role in traumatic isthmic rupture, as it avoids the thoracotomy-related morbidity, aortic cross clamping, and cardiopulmonary bypass. Additionally to the technical difficulties of open repair, multi-trauma patients may not tolerate the manipulations necessary to undergo open surgery, due to concomitant injuries...

Cerebrospinal fluid (CSF) is known to be reabsorbed by the lymphatic vessels and drain into the lymph nodes (LNs) through peripheral lymphatic vessels. In the peripheral lymphatics, the contractile pumping action of lymphangions mediates lymph drainage; yet it is unknown whether lymphatic vessels draining cranial and spinal CSF show similar function. Herein, we used non-invasive near-infrared fluorescence imaging (NIRFI) to image (i) indocyanine green (ICG) distribution along the neuraxis and (ii) routes of ICG-laden CSF outflow into the lymphatics following intrathecal lumbar administration...

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...
