Diagnostic lumbar puncture was performed on 76 neurological inpatients. They were randomly allocated to one of four bed rest positions for four hours following the procedure (supine and horizontal, prone and horizontal, supine with head-down tilt and prone with head-down tilt) after which they were allowed to get up. There was no substantial or significant difference in the incidence of headach...

Intradural epidermoid tumors occur more often in patients with a history of one or more lumbar punctures (1-4). It is hypothesized that they result from skin fragments introduced into the thecal sac during lumbar puncture and that they differ from the congenital heterotopic lesions. This report details the characteristic patient history , the water-soluble myelographic findings, and the MR appe...

Background. Complications of spinal anaesthesia (SpA) range between 1 and 17%. Habitus and operator experience may play a pivotal role, but only sparse data is available to substantiate this claim. Methods. 161 patients were prospectively enrolled. Data such as spread of block, duration of puncture, number of trials, any complication, operator experience, haemodynamic parameters, was recorded a...

A hundred years ago, Guillain, Barré and Strohl described a syndrome with a predominant motor acute or subacute polyneuritis, albumin-cytologic dissociation in the cerebrospinal fluid, and a benign course. Before them, many other authors, such as Landry, Duménil, Osler, and Grainger Stewart had described similar cases although they had not performed lumbar punctures. In this work, we outline ce...

STUDY DESIGN An in vitro biomechanical study using aged human and adolescent porcine discs. OBJECTIVES To find the leakage pathway and effect of needle gauge on the degree of disc injury post anular puncture. SUMMARY OF BACKGROUND DATA Spinal needles are widely used for minimal invasive disc surgeries and disc degeneration/regeneration research. Applications of anular puncture require diffe...

Background: We are the first to report one-staged resection of a spinal metastasis from malignant cranial hemangiopericytoma after preoperative OnyxTM-20 embolization by direct percutaneous puncture. Spinal metastases from cranial hemangiopericytoma are extremely rare. Surgical morbidity of these highly vascularized tumours results mainly from excessive blood loss. Preoperative embolization of ...

Congenital lumbar spinal stenosis is an uncommon condition that is often asymptomatic in young adults. Herein, we document the first reported occurrence of acute radicular back pain and associated congenital lumbar spinal stenosis in a healthy 24-year-old woman undergoing an epidural blood patch for treatment of a post-dural puncture headache related to an accidental dural puncture sustained du...

OBJECTIVE To report our experience of minimally invasive percutaneous nephrolithotomy(MPCNL) in managing upper urinary tract calculi complicated with severe spinal deformity. MATERIALS AND METHODS Between August 2001 to December 2012, 16 upper urinary calculi in 13 patients with severe spinal deformity were treated by MPCNL. Preoperative investigation of the respiratory function, evaluation o...

INTRODUCTION Spinal anesthesia produces a profound and uniformly distributed sensory block with rapid onset and muscle relaxation, and results in complete control of cardiovascular and stress responses. Ketamine is an anesthetic agent that is widely used for pediatric sedations in settings where safety and efficacy of the agents are mandatory because of limited healthcare resources. The authors...

We read with great interest study conducted by Mosaffa et al. (1), designed to compare the rate of post-dural puncture headache (PDPH) in median and paramedian approaches in spinal anesthesia in the September issue of Anesthesiology and Pain Medicine. Spinal anaesthesia has been used in patients from preterm neonates to aged over a hundred years. At present it is a gold standard for many differ...
