INTRODUCTION Complications after lumbar anaesthesia and epidural blood patch have been described in patients with congenital small spinal canal and increased epidural fat or epidural lipomatosis. These conditions, whether occurring separately or in combination, require magnetic resonance imaging for diagnosis and grading, but their clinical significance is still unclear. CASE PRESENTATION A 3...

BACKGROUND The spinal dura is anchored within the vertebral canal by connective tissue in the epidural space as well as the spinal roots. Inadvertent disruption of these dural attachments may lead to durotomy and cerebrospinal fluid (CSF) leaks. We observed well-developed connective tissue ligaments connecting the lumbar dura to the spinal column and examined these tissues microscopically. ME...

Spinal dural arteriovenous fistulas are a rare and underdiagnosed pathology. Rapid diagnosis and treatment are, however, major determining factors for the outcome of the disease. The spontaneous course of this pathology can result in a substantial degree of morbidity that may be irreversible. Proper interpretation of the MRI imaging, and particularly the medullar angiography, allow for an appro...

Spinal reconstruction with pedicle screw-based instrumentation and rhBMP-2 in patients with neurofibromatosis and severe dural ectasia and spinal deformity: Report of two cases and a review of the literature.

Imaging in spinal dural arteriovenous fistula 2 ARC Publishing Background Spinal dural arteriovenous fistula (SDAVF) is a rare condition, but accounts for great disability in those affected. SDAVF are more common in men and typically present in the fifth and sixth decades of life [1]. The patients usually present with lower extremity spastic weakness, sensory symptoms, bowel/bladder disturbance...

PURPOSE A comparison of MRI and computed tomography-myelography (CTM) for lumbar intracanalar dimensions. To compare the capability and reproducibility of MRI and CTM in measuring the cross-sectional morphology of intracanalar lesions of the lumbar spine. MATERIALS AND METHODS MRI and CTM of lumbar disc levels from 61 subjects with various lumbar spinal diseases were studied. Dural area, dura...

BACKGROUND AND PURPOSE The craniospinal epidural spaces can be categorized into 3 different compartments related to their specific drainage role of the bone and central nervous system, the ventral epidural, dorsal epidural, and lateral epidural groups. We propose this new classification system for dural arteriovenous shunts and compare demographic, angiographic, and clinical characteristics of ...

Introduction Dural puncture is a commonly performed invasive procedure for various indications like diagnostic lumbar puncture, spinal anaesthesia, myelography and intrathecal chemotherapy. However, in anaesthesia practice apart from intentional dural puncture as in spinal anaesthesia, unintentional dural puncture can also occur while performing epidural anaesthesia or analgesia for various ind...

Cerebral venous sinus thrombosis is an uncommon but potentially lethal condition that can present with headache, focal deficits, seizures, altered mental status, and papilledema. Nontraumatic dural sinus thrombosis is associated with medical conditions such as oral contraceptive use, pregnancy, dehydration, coagulopathies, connective tissue disorders, and leukemia. Traumatic dural sinus thrombo...
