The effectiveness of endoscopic epidurolysis in treatment of degenerative chronic low back pain: a prospective analysis and follow-up at 48 months.
The aim of this prospective study was to evaluate the efficacy of endoscopic epidurolysis in the treatment of degenerative chronic low back pain. Two hundred and thirty four patients affected by chronic low back pain, with VAS ≥ 5 and Oswestry Low Back Pain Disability Index (ODI) from 0 to 60% (0-20%, group A; 20-40%, group B; 40-60%, group C) were enrolled and treated prospectively with endoscopic epidurolysis by means of a flexible fiberoptic endoscope introduced into the caudal epidural space and by the intermittent instillation of saline solution added with 150 UI hyaluronidase. Targeted application of ozone (8 ml; 38 γ/ml) and 50 mg ciprofloxacin close to the abnormal areas was also performed. ⋯ The treatment significantly reduced VAS score in all three groups of patients starting from the first week and throughout the entire follow-up period (P < 0.001). Disability Index (ODI) too showed encouraging results (P < 0.001) that was particularly evident at 3 months and maintained up to long-term follow-up intervals. Epiduroscopy by mechanical adhesiolysis and administration on targeted areas of ciprofloxacin and ozone seems to be, in this prospective study, an effective technique to provide a sensible and persisting pain relief and act of improving ODI in chronic low back pain.

Percutaneous coblation nucleoplasty in patients with contained lumbar disc prolapse: 1 year follow-up in a prospective case series.
Nucleoplasty appears a successful minimally-invasive treatment for symptomatic contained disc herniation (protrusion). The purpose of this prospective study was to assess the effectiveness of nucleoplasty for alleviating pain and dysfunction in our patients. ⋯ This disc decompression procedure was a safe and effective treatment option for carefully selected patients affected by low back and leg pain due to contained disc herniation.

Clinical TrialRole of controlled lumbar CSF drainage for ICP control in aneurysmal SAH.
a prospective study of lumbar CSF drainage in the setting of raised intra-cranial pressure refractory to medical management and ventriculostomy placement is presented. There has been increasing data that this may be a effective and safe intervention for reduction of ICP. ⋯ we have shown that controlled lumbar drainage is a safe, efficacious and minimally invasive method for treatment of elevated ICP which refractory to medical management. Ventriculostomies are always placed before utilizing lumbar drains to minimize the risk of cerebral herniation. We would advocate making controlled lumbar drainage a standard part of ICP control protocols.

The new MRI modalities "BPAS and VISTA" for the diagnosis of VA dissection.
Recently VA dissection has drawn attention as a relatively common cause of stroke because of the introduction of MRI as a diagnostic technique. Basiparallel anatomic scanning (BPAS) was designed to visualize the surface appearance of the vertebrobasilar artery within the cistern. Volumetric isotropic TSE acquisition (VISTA) is a sort of black blood imaging method to evaluate the arterial wall and lumen. In this study, we aimed to evaluate the efficacy of the new MRI modalities "BPAS and VISTA," and to present a retrospective analysis of our experience with the diagnosis. ⋯ Dilatation of the external diameter was shown highly frequently in VA dissections. In addition, a discrepancy between BPAS and MRA as well as the intramural hematoma on VISTA was found comparatively frequently. BPAS and VISTA are minimally invasive and useful methods as screening tests.

Regardless of numerous efforts there is no prophylactic treatment proven to be effective in the prevention of cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH). As systemic administration of vasoactive drugs has been associated with significant side effects and insufficient efficacy, intrathecal administration of nicardipine prolonged-release implants (NPRI) has been developed. At the time of surgical clipping of the ruptured aneurysm, NPRIs are positioned next to the large cerebral arteries. ⋯ A separate patient series demonstrated the efficacy of fewer NPRIs in the perichiasmatic cistern. Further investigations were performed in comparison to coiled patients and with intraventricular implantation of NPRIs, which had a less pronounced effect. Overall, NPRIs are a most promising option for the prevention of cerebral vasospasm after SAH and large controlled trials are needed to further confirm these results.
