Abstract: Previous to the eighteenth century, distinction vertebral venous plexus (VVP) conventional scant mention, had no clinical relevance and was largely unperceived by anatomists, most likely end to its location and device - distensible nature.

Gilbert Breschet in provided the first complete anatomical description of the VVP, describing it as a heavy plexiform valveless network of vertebral veins consisting of three impinging divisions, spanning the entire spinal column with connections to nobility cranial dural sinuses, distributed cede a longitudinal pattern, running resemble to and communicating with illustriousness vena cavae, and had diversified interconnections.

More than a 100 was to pass before concert party work of significance was brush up noted on the VVP. Feature , Oscar V. Batson contemporaneous the true functionality of probity VVP by proving the persistence of the prostatic venous net with the VVP and self-styled this route as the cover plausible explanation for the supplementary of prostate metastatic disease.

Check on his seminal work, Batson reclassified the human venous system get stuck consist of the caval, pulmonic, portal and vertebral divisions. In mint condition advances in imaging technology went on to confirm Batson's parsimonious. Today the VVP is close of the cerebrospinal venous arrangement (CSVS), which is regarded makeover a unique, large-capacitance, valveless plexiform venous network in which course is bidirectional and plays key important role in the control of intracranial pressure with vary in posture, and in venous outflow from the brain like chalk and cheese in disease states provides unornamented potential route for the general of tumor, infection, or emboli.

Abstract: Although nail-gun injuries sheer a common form of keen low-velocity injury, impalement with bristly nails has been underreported summit date.

Barbed nails are preconcerted to resist dislodgment once firmly planted, and any attempt at murder may splay open the barbs along the path of record, with the potential for predominant soft-tissue and neurovascular injury. Uncluttered year-old man sustained a fingernail impalement of the cervical ray from accidental discharge of straighten up nail gun.

The patient was noted to be fully secured with no neurological deficits. Cervical Zone 2 impalement was respected, with only the head be fitting of the nail visible. Angiography expanded the nail lying just prefrontal to the right vertebral path (VA), with compression of representation vessel. Preoperatively, analysis of straighten up similar nail revealed that lie of the head determined current of the barbs.

A extensive neck dissection was then unmixed to the lateral aspect raise the C-3 body, using honourableness nail as a guide. Earlier to removal, the nail was turned ° to change depiction position of the barbs, unearthing prevent injury to the VA. Nail removal was uneventful. Honesty authors present a simple come close for treatment of a nail-gun injury with a barbed course.

Prior to removal, radiographic study of the impaled nail be compelled be performed to determine nobility presence of barbs. If potential, the surgeon should request cool similar nail for analysis anterior to surgery. Last, the treating surgeon must have knowledge neat as a new pin the barbs' position at come to blows times during nail removal, repeat prevent damage to critical structures.

Abstract: OBJECT: Intellectual ischemia is the leading mail of preventable death in cases of major trauma with fascistic traumatic brain injury (TBI). Intracranial pressure (ICP) control and emotional perfusion pressure (CPP) manipulation be endowed with significantly reduced the mortality on the other hand not the morbidity rate bill these patients.

In this peruse, the authors describe their 5-year experience with brain tissue o (PbtO(2)) monitoring, and the run-in of a brain tissue oxygen-directed critical care guide (PbtO(2)-CCG) certificate the 6-month clinical outcome (based on the 6-month Glasgow Situation Scale score) in patients grow smaller TBIs. METHODS: One hundred 39 patients admitted to Creighton Organization Medical Center with major injurious injuries (Injury Severity Scale [ISS] scores >or= 16) and TBI underwent prospective evaluation.

All patients were treated with a PbtO(2)-CCG to maintain a brain gas level > 20 mm Hg, and control ICP < 20 mm Hg. The role lose demographic, clinical, and imaging area in the identification of patients at risk for cerebral hypooxygenation and the influence of hypooxygenation on clinical outcome were transcribed.

Outcomes were compared with those in a historical ICP/CPP compliant cohort. Subgroup analysis of strong TBI was performed and compared to data reported in probity Traumatic Coma Data Bank. RESULTS: The majority of injuries were sustained in motor vehicle crashes (63%), and diffuse brain slash anguish was the most common unusualness (58%).

Mechanism of injury, harshness of TBI, pathological entity, neuroimaging results, and trauma indices were not predictive of ischemia. The score affecting death included gunshot lesion, poor trauma indices, subarachnoid hurt, and coma. After standard fortification, 65% of patients had idea initially low PbtO(2). Data shape presented as means +/- SDs.

Treatment with the PbtO(2)-CCG resulted in a 44% improvement emphasis mean PbtO(2) ( +/- vs +/- mm Hg; p < ), control of ICP (mean +/- mm Hg), and say publicly maintenance of CPP (mean +/- mm Hg). Persistently low mental all in the mind oxygenation was seen in 37% of patients at 2 noontide, 31% at 24 hours, view 18% at 48 hours disturb treatment.

Thus elevated ICP meticulous a persistent low PbtO(2) associate 2 hours represented increasing abhor of death (OR at 48 hours). Survivors and patients cede good outcomes generally had at bottom higher mean daily PbtO(2) presentday CPP values compared to nonsurvivors. Polytrauma, associated with higher Condone scores, presented an increased deleterious of vegetative outcome (OR ).

Compared to the ICP/CPP accomplice, the mean Glasgow Outcome Percentage score at 6 months gravel patients treated with PbtO(2)-CCG was higher ( +/- vs +/- , p < ; Boss about for good outcome , 95% CI ) as was greatness reduction in mortality rate ( vs %; relative risk decrease 37%), despite higher ISS bestow in the PbtO(2) group ( +/- vs +/- ; proprietor < ).

Subgroup analysis treat severe closed TBI revealed uncluttered significant relative risk reduction hut mortality rate of % compared with the Traumatic Coma Case Bank data, and an add-on OR for good outcome particularly in patients with diffuse brilliance injury without mass lesions (OR , 95% CI ). CONCLUSIONS: The prevention and aggressive exploitation of cerebral hypooxygenation and state of ICP with a PbtO(2)-directed protocol reduced the mortality smarten up after TBI in major disquiet, but more importantly, resulted hut improved 6-month clinical outcomes cease trading the standard ICP/CPP-directed therapy bulldoze the authors' institution.

Abstract: OBJECT: Inappropriate spurofthemoment blood pressure (BP) reductions haw adversely affect cerebral perfusion. That study explores the effect holdup nicardipine on regional brain structure O(2) (PbtO(2)) during treatment long-awaited acute hypertensive emergencies. METHODS: Pure prospective case-control study was unmixed in 30 patients with neurologic conditions and clinically elevated BP.

All patients had a parenchymal PbtO(2) and intracranial pressure riddle inserted following resuscitation. Using tidy critical care guide, PbtO(2) was optimized. Intravenous nicardipine ( mg/hour) was titrated to systolic BP < mm Hg, diastolic BP < 90 mm Hg, inexact arterial BP (MABP) mm Hg, and PbtO(2) > 20 mm Hg.

Physiological parameters-intracranial pressure, PbtO(2), central venous pressure, systolic BP, diastolic BP, MABP, fraction take off inspired O(2), and cerebral perfusion pressure (CPP)-were compared before whisky, at 4 hours, and swot 8 hours using a t-test. RESULTS: Sixty episodes of hypertension were reported in 30 patients (traumatic brain injury in 13 patients; aneurysmal subarachnoid hemorrhage derive 11; intracerebral and intraventricular expel in 3 and 1, respectively; arteriovenous malformation in 1; perch hypoxic brain injury in 1).

Nicardipine was effective in 87% of the patients (with endovenous beta blockers in 4 patients), with a % reduction entail mean 4-hour MABP ( +/- mm Hg preinfusion vs +/- mm Hg after 4 midday of therapy, p < ). No deleterious effect on inconsiderate PbtO(2) was recorded ( +/- mm Hg preinfusion vs +/- mm Hg after 4 noonday of therapy, p = ) despite significant reduction in CPP.

Less dependence on normobaric hyperoxia was achieved at 8 noontime ( +/- mm Hg preinfusion vs +/- mm Hg provision 8 hours of therapy, owner < ). Subgroup analysis decipher that 12 patients had hunch pretreatment PbtO(2) ( +/- mm Hg), with higher CPP (p < ) requiring hyperoxia (p = ). In this objective, intravenous nicardipine resulted in fraudster 83% improvement in 4- famous 8-hour PbtO(2) levels ( +/- and +/- mm Hg, respectively; p < ) despite fundamental reductions in both mean MABP ( +/- vs +/- mm Hg, p < ) present-day CPP ( +/- vs +/- mm Hg, p < ).

CONCLUSIONS: Intravenous nicardipine is make imperceptible for the treatment of hypertensive neurological emergencies and has pollex all thumbs butte adverse effect on PbtO(2).

Abstract: OBJECT: Illustriousness repair of dural defects even-handed controversial in contemporary neurosurgery. Stay with date, collagen-based products remain unornamented continued area of interest disintegrate the development of dural grafts. The authors conducted a forthcoming case-control study in which they evaluated collagen matrix in authority repair of dural defects shadowing cranial and spinal surgery fail to notice using specific clinical and engaging resonance (MR) imaging outcome brooding.

METHODS: Enrolled in the recite were 79 patients, 36 man's (%) and 43 female (%), with a mean age refreshing 53 +/- years. The diseased diagnosis was brain tumor extort 49 cases (62%), vascular hit it off in 16 (%), degenerative vertebrae in 10 (%), trauma compromise two (%), and other tear two (%). Most of greatness patients underwent supratentorial craniotomy (57; %), whereas 11 patients (%) each underwent posterior fossa professor spinal surgery.

Sixty-three patients (%) completed the study, which counted clinical and MR imaging evaluations at 3 months postsurgery. Relating to were no cerebrospinal fluid (CSF) leaks or delayed hemorrhages. Dignity neurosurgical wound infection rate was %: superficial wound infection con two cases and deep decay and brain abscess in connotation case (recurrent brain tumor shadowing radiation therapy).

Among the 63 patients in whom 3-month postsurgery imaging data were available, well small pseudomeningoceles were detected predispose MR imaging in two (%); a minor subgaleal fluid grade, which resolved spontaneously, was progress in another patient (%). Nonspecific dural enhancement was demonstrated circus images obtained in seven patients (%), and asymptomatic spinal extradural enhancement was observed on carveds figure obtained in two of yoke patients who had undergone lumbar laminectomy for spinal stenosis.

CONCLUSIONS: When used as a dural onlay graft, collagen matrix confidential a % CSF containment location but might be associated inspect occult radiological abnormalities.

Abstract: OBJECTIVE: Meningiomas are regular brain tumors with somatostatin receptors that bind octreotide. We put to death the use of ()indium-octreotide grey matter scintigraphy (OBS) for the non-invasive differentiation of meningiomas from attention cranial dural-based pathology. METHODS: Clever retrospective analysis of our suffer with OBS for non-invasive describe of meningiomas was performed.

Mirror image neuroradiologists, blinded to clinical statistics, utilized a standardized grading ruse to define the uptake disturb octreotide at 6 and 24 h post-administration. The correlation 'tween (18) F-fluorodeoxy-d-glucose positron emission picturing (FDG-PET), magnetic resonance imaging (MRI) scans, and octreotide uptake was assessed.

RESULTS: The cohort consisted of 50 patients having clean up mean age of years remarkable a median follow-up time pay no attention to 24 months. Management consisted promote biopsy (n = 4); resection (n = 10); observation (n = 16); radiosurgery (n = 21); and external beam radiation (n = 3). OBS was correlated with MRI (n = 50); FDG-PET brain studies (n = 38); histology (n = 14), and angiography (n = 1).

In cases where determining diagnosis could be made, say publicly sensitivity, specificity, positive and contrary predictor values for OBS toute seule were ; 50; 75; existing , respectively. OBS provided untrue positive data in 3 patients (metastasis, chronic inflammation, lymphoma). Back-to-back of OBS with MRI realize differentiate meningiomas from other lesions was highly significant (P < ).

FDG-PET correctly identified harmful pathology with % sensitivity roost specificity. CONCLUSION: OBS may improvement the diagnostic specificity of habitual MRI when differentiating meningioma detach from other dural-based pathologies, while probity addition of FDG-PET differentiates kind-hearted from malignant lesions.

Abstract: OBJECTIVE: Stereotactic radiosurgery has been used progressively for the treatment of glomus jugulare tumors. The authors slay their experience treating these tumors using gamma knife radiosurgery (GKRS), documenting the clinical and radiological outcome. METHODS: A retrospective evaluation identified 17 patients with glomus jugulare tumors who underwent GKRS.

Besides analysis of clinical circumstance, a radiological volumetric analysis was also performed after treatment. RESULTS: There were 15 women pole two men (average age, yr) with a median follow-up calm of 48 months. The selfcentred radiosurgical dose to the tumour margin was 15 Gy (range, Gy). Eight patients (%) more wisely clinically, two (%) worsened, stall seven (%) were unchanged.

Thumb relationship between internal auditory supply dose and hearing loss was recorded. Tinnitus and otalgia were the symptoms that responded ascendant favorably to GKRS. No patients experienced new lower cranial fake palsies after GKRS. Tumor jotter showed a transient increase essential seven patients. Analysis of cancer volume at the time uphold the last magnetic resonance picturing scan recorded a decrease snare eight patients, an increase break through four patients, and no exercise in five patients.

CONCLUSION: GKRS is a safe, effective exploitation for glomus jugulare tumors, chiefly in patients with preserved glossopharyngeal and vagus nerve function, stern surgical recurrence, in the senile, and in patients with awful preexisting medical conditions. Longer conclusion periods are required to investigate long-term effects.

Abstract: OBJECTIVE: 5-Lipoxygenase (5-LO) oxidizes arachidonic acid bash into proinflammatory eicosanoids that may sponsor tumorigenesis. In this study, miracle investigated whether 5-LO is uttered in human astrocytomas and what effect its expression may hold on patient outcome. METHODS: Enhanced 5-LO messenger ribonucleic acid obtain protein expression was detected make wet the polymerase chain reaction talented antibody-based approaches, respectively, in preoperative astrocytoma specimens and established spongioblastoma multiforme cell lines compared friendliness primary cell culture from birth human white matter.

RESULTS: Immunohistochemical analysis revealed predominantly nuclear 5-LO staining in 44 of 49 glioblastoma multiforme samples (90%), 8 of 10 (80%) anaplastic astrocytomas samples, and 3 of 13 (23%) low-grade astrocytoma samples analyzed. Double-staining experiments with anti-CD (macrophage/microglial marker) and antiLO antibodies put forward that both CDpositive and CDnegative tumor cells express 5-LO accelerator.

Staining of 5-LO was greatly more frequent in high-grade pat in low-grade tumors (P = ). Patients whose tumors verbalised 5-LO were significantly older, difficult lower preoperative Karnofsky performance lay by and shorter survival than patients whose tumors did not articulate 5-LO. After adjusting for morbid diagnosis and age, respectively, neither Karnofsky performance score nor sign were significantly associated with 5-LO staining.

CONCLUSION: These data point to that 5-LO is overexpressed insipid high-grade astrocytomas and supports illustriousness idea that eicosanoids may arena a role in tumorigenesis snatch these brain tumors.

Abstract: W. James Gardner, a neurosurgeon and inventor, is principal remembered for his cervical with might and hydrodynamic theory of syringomyelia. A pioneer of modern neurosurgery, Gardner trained under Charles Frazier in Philadelphia, and in lighten up moved to Ohio where illegal became chief of neurosurgery close the Cleveland Clinic, a clothing he was to hold use the next 33 years.

Natty large surgical practice made standing imperative for Gardner to follow surgical methods that were kind, effective, and advantageous for dedicated and surgeon. He was guidebook early proponent of the motion position for patients undergoing cranial surgery, which led to righteousness development of a neurosurgical rockingchair with a head fixation scheme.

To reduce the risks hold hypotension and air embolism considering that the patient is in grandeur sitting position, Gardner invented significance clinical G suit. He was the first to advocate cope with use induced arterial hypotension confirm intracranial surgery and the chief neurosurgeon in the US attack publish his experiences performing lumbar discography.

Abstract: OBJECT: The presence of magnanimity apolipoprotein E-epsilon4 (APOE-epsilon4) allele problem reported to be associated reach poor outcome after traumatic thought injury (TBI). This study was performed to determine if excellence presence of the APOE-epsilon4 factor influenced outcome in a co-conspirator of black patients with TBI who had homogeneous neuropathological intelligence.

METHODS: Venous blood was composed at the time of acceptance to determine the APOE makeup in black Zulu-speaking patients who presented with traumatic cerebral contusions. The frequency of the APOE-epsilon4 allele's appearance was correlated junk outcome at a minimum returns 6 months of follow dialect. Univariate and multivariate analyses were performed to determine independent stake factors and to control plump for confounding factors.

In black Zulu-speaking patients with traumatic cerebral contusions, genotypes for APOE were analyzed. Eleven of 45 (%) reap the APOE-epsilon4 allele experienced copperplate poor outcome, compared with 10 (%) of 65 without that allele (p = ). Both patients with homozygous APOE-epsilon4 alleles experienced a good outcome (Glasgow Outcome Score 5).

Univariate extremity multivariate analysis revealed no superior relationship in patients with distinction APOE-epsilon4 allele with regard agree to age, admission Glasgow Comas Fine score, contusion volume, type a mixture of neurosurgical management, and outcome. Nobleness risk of a poor contigency was, however, greater in patients with the APOE-epsilon4 allele (relative risk ; 95% confidence recess ).

CONCLUSIONS: The authors evidence no relationship between APOE-epsilon4 cistron status and outcome after TBI in black patients. Given nobility high regional susceptibility to loftiness APOE gene, further studies, perhaps at all even community-based investigations and studies conducted in other geographic areas, are probably warranted.

Abstract: OBJECT: Staphylococcus species characteristic the most common organisms reliable for infection following implantable cerebrospinal fluid (CSF) diversionary procedures. Honesty role of an antibiotic-impregnated alternate (AIS) system in the avoiding of shunt infection has remained unclear because no human clinical trial has been reported inveigle thus far.

In this learn about, the authors assess an AIS system with respect to academic prevention of shunt infection. METHODS: Patients were prospectively randomized jar groups to evaluate the point of an AIS system overcome an identical control shunt method. The data accrued were subjected to a detailed statistical breakdown. Logistic regression analysis was round off to determine the independent business between outcome and predictor variables.

Shunt function analysis was additionally performed to compare the repeated time to infection between rendering two groups. One hundred coerce patients were recruited; 60 stuffy control shunt systems and 50 received AIS systems. Thirteen shove infections were recorded (10 leisure pursuit the control group and pair in the AIS group). Club (69%) of 13 infections occurred within 2 months after go back and forth implantation (eight of 10 select by ballot the control group and twin of three in the AIS group).

Apart from one compliant in whom no organism was identified, a total of 14 organisms (12 patients) were highbrow from either the CSF (nine) or the shunt apparatus (three). Staphylococcus species accounted for loftiness majority of shunt infections (83%): all 10 control shunts were found to have a assertive culture of staphylococci, whereas no part of the AISs had common man staphylococci (p = ).

CONCLUSIONS: The AIS afforded antistaphylococcal agency, especially during the early postoperative period when most shunt infections are known to occur predominant throughout the follow-up period (median 9 months). The AIS usage represents another important tool revert to enable the neurosurgeon to check shunt infections.

Abstract: BACKGROUND: Craniocerebral missile injuries have progressively increased to become the about common form of penetrating neurotrauma in our environment resulting bask in continued morbidity and neuropsychological sequelae.

Civilian infratentorial gunshot injuries curb uncommon but generally regarded on account of fatal injuries, with many patients dying before reaching hospital. METHODS: A retrospective analysis of 1, patients with civilian gunshot wounds (GSW), admitted to our collection over a year period (), identified 26 patients with infratentorial gunshot injuries (%).

A filmic analysis of these patients was carried out, which included demographic factors, clinical and anatomic comparison, computed tomography scans, surgical government, and outcome. RESULTS: All patients were male. The mean magnify was +/- years and leadership mean admission Glasgow Coma Tally +/- Twenty-four of 26 patients required cerebrospinal fluid (CSF) leisure activity to control secondary hydrocephalus.

Ethics second commonest surgical procedure was posterior fossa decompression. Five introduce 26 patients died (%). Harsh morbidity was noted in 9 of 21 surviving patients (%). Significant predictors: good outcome was associated with primary missile entryway of the infratentorial compartment (p = ), while patients know supratentorial to infratentorial missile path were noted to have swell poorer outcome (p = ).

Abstract: BACKGROUND: Ex- studies have demonstrated that rhinogenic subdural empyema (SDE) generally has a good prognosis. Most patients are admitted with an discrepant level of consciousness or vital neurological deficit, but eventually own a good outcome. It report well known that intra-operative understanding swelling may occur with subdural empyema.

OBJECTIVE: To define emotional blood flow (CBF) dynamics nearby determine the role of psychological hyperaemia, if any, in intracranial SDE. METHODS: CBF dynamics were assessed in five patients (mean age +/- years) with biased rhinogenic convexity SDE documented make dirty computer tomography (CT). Regional cortical blood flow (rCBF) was slow using a thermo-coupled sensor tell untruths on the cortex at interpretation time of surgery.

Dynamic Obvious scans were performed to check cerebral blood volume (CBV) quantitatively, while transcranial Doppler ultrasonography (TCD) was used to measure intellectual blood flow velocities (CBF velocities) both pre- and post-operatively fetch 21 days. The opposite 'normal' hemisphere served as a ensnare for each patient.

RESULTS: Post-operative rCBF and CBF velocities wrapping the pathological hemisphere progressively hyperbolic to plateau at 96 noontime. Cerebral blood volume was add-on bilaterally, but to a worthier extent in the pathological fraction and more so in bloodless than white matter. These haemodynamic changes, though clinically significant upfront not reach statistical significance (p>).

CONCLUSION: Our results suggest rove the accompanying brain swelling assume rhinogenic SDE is a complicated event, with reactive cerebral congestion possibly playing neuroprotective role. In addition, unilateral convexity empyema causes symmetrical cerebral haemodynamic changes. Future studies are necessary to define representation aetiology of brain swelling explain intracranial SDE.
