Posterior ‘Motion Preserving’ Procedures (Frykholm)

2019

Cervical radiculopathy from degenerative disease is a common problem with an incidence of 0.83–1.79 per 1000 person years. It can be caused by a cervical disc herniation, bony foraminal stenosis or spinal canal stenosis. Upon failure of conservative therapy or a significant motor deficit surgical treatment is indicated. A posterior cervical foraminotomy is one surgical option for the treatment of selected patients with lateral cervical disc herniations.

Endothelin-1 concentrations in the internal jugular and azygous veins in multiple sclerosis patients: the results of a pilot study

2014

Objectives: In this pilot study we examined the potent vasoconstrictor, endothelin-1, in the blood of multiple sclerosis patients in the context of chronic cerebrospinal venous insufficiency hypothesis. For this purpose we measured endothelin-1 concentrations in blood samples that were obtained during selective catheterisation of the main veins draining the central nervous system: the internal jugular veins and the azygous vein. Material and methods: We measured endothelin-1 concentrations in peripheral blood in nine multiple sclerosis patients and five healthy controls. In multiple sclerosis patients this peptide was also evaluated in blood samples obtained from the internal jugular veins …

Intraoperative Sonographie bei lumbalen Bandscheibenvorfällen

2008

UNLABELLED Intraoperative ultrasound of the spine has been used in neurosurgery (tumours) and traumatology (reposition of fractured vertebral bodies fragments). AIM To describe initial experiences with this method and to document the opportunities and problems. METHOD 24 nucleotomies were documented and evaluated. Sonography was performed using a 7.5 MHz sector probe and a typical surgical approach. RESULTS In 21 of 24 cases, imaging of intraspinal structures was possible. The complete extraction of the herniated disk could be documented. In 3 cases the examination failed because the probe was too large to be pushed down between the spinous processes and the wound retractor to the operative…

Diagnosis, treatment, and analysis of long-term outcomes in idiopathic normal-pressure hydrocephalus

2007

To the Editor:We read with interest the article by McGirt et al. (9) entitled“Diagnosis, Treatment, and Analysis of Long-term Outcomes inIdiopathic Normal Pressure Hydrocephalus.” The authors con-clude that gait impairment is the primary symptom that inde-pendently predicted improvement after shunting. The studyincluded 132 patients, 129 (98%) of whom had gait impairmentas a feature. We would like to comment on this particular selec-tion criterion, as well as improvements in the Mini Mental StateExamination (MMSE) as the sole measure of postoperative cog-nitive improvement.One of the inclusion criteria for this study was presentationwith two or more features of the classic triad. Thus, the …

Chronic cerebrospinal venous insufficiency: current perspectives

2014

This review summarizes the research to date on chronic cerebrospinal venous insufficiency (CCSVI). CCSVI was initially defined as a clinical syndrome comprising stenoses of the internal jugular and/or azygos veins, characterized by collateral venous outflows and reduced cerebral blood flow, and was found primarily in patients with multiple sclerosis. However, the published evidence on CCSVI is very discordant. Catheter venography studies gave a regular picture, with the majority of patients with multiple sclerosis presenting with demonstrable outflow abnormalities in the veins draining the central nervous system. The prevalence of these lesions was over 50%, and even higher (about 90%) when…

An overview of randomized controlled trials on endovascular treatment for chronic cerebrospinal venous insufficiency in multiple sclerosis patients

2020

AbstractAbout ten years ago it was hoped that venous angioplasty for abnormal veins, primarily the internal jugular veins, will be a much awaited treatment for multiple sclerosis. Yet, a majority of randomized clinical trials on endovascular treatment for chronic cerebrospinal venous insufficiency did not reveal clinical efficacy of these procedures in multiple sclerosis patients. Still, a detailed analysis of these trials suggests that they were poorly designed, underpowered and endovascular techniques used were often far from being optimal. Nonetheless, even considering weak points of these trials, it can be concluded that venous angioplasty should not be used as a routine treatment modal…

Die Sonoanatomie des Spinalkanales der LWS

2008

UNLABELLED Results of an Experimental Study and Report of Intraoperative Application: AIM Intraoperative sonography has been used in neurosurgery (especially in tumors) and in traumatology (assess reduction of dorsal vertebral body fragments). This study was performed to determine the value of sonography in detecting vertebral disc tissue. RESULTS We examined 6 specimens of the Lumbar spine using the extended flavectomy approach. We found that sono-anatomy was reproducible and that the assessable area was large enough to make sonography useful for detection of sequesters. Dislocated vertebral disc tissue could be differentiated clearly from original disc tissue and from other intraspinal st…

Aulogous fibrin sealant (Vivostat(®)) in the neurosurgical practice: Part II: Vertebro-spinal procedures.

2015

Background Epidural hematomas, cerebrospinal fluid fistula, and spinal infections are challenging postoperative complications following vertebro-spinal procedures. We report our preliminary results using autologous fibrin sealant as both fibrin glue and a hemostatic during these operations. Methods Prospectively, between January 2013 and March 2015, 68 patients received an autologous fibrin sealant prepared with the Vivostat(®) system applied epidurally to provide hemostasis and to seal the dura. The surgical technique, time to bleeding control, and associated complications were recorded. Results Spinal procedures were performed in 68 patients utilizing autologous fibrin glue/Vivostat(®) to…
