INTRODUCTION Percutaneous nephrolithotomy is the most complicated stone surgery technique to learn. The steep learning curve is related mainly to obtaining precise renal access by puncturing the targeted calyx. A minimally misaligned puncture may lead to torrential bleeding, failure of the surgery, and complications. Renal puncture can take a long time, and the increased fluoroscopic time is a ...
Correction Following the publication of our article [1] an error in the case presentation section was noted. In the description of the lumbar puncture procedure, we incorrectly stated the units of the opening pressure. Upon lumbar puncture, performed in the lateral decubitus position, an opening pressure of 40 mm of water was documented. Should read: Upon lumbar puncture, performed in the later...
BACKGROUND AND PURPOSE Recently, the performance of C1-2 punctures for cervical myelography was challenged in a medicolegal proceeding as being below the standard of care. We sought to examine current neuroradiologic practices and opinions on the technique. MATERIALS AND METHODS An 11-question survey was sent to 120 program directors of neuroradiology via e-mail links regarding cervical myelo...
The structure and mechanics of fish scales display unusual and attractive features which could inspire new protective materials and systems. This natural material is therefore attracting attention over the past few years, and recent work demonstrated the remarkable performance of individual fish scales. A puncture event as would occur from a predator's attack however involves more than one scal...
PURPOSE The pathophysiology of discogenic low back pain is not fully understood. Tetrodotoxin-sensitive voltage-gated sodium (NaV) channels are associated with primary sensory nerve transmission, and the NaV1.7 channel has emerged as an analgesic target. Previously, we found increased NaV1.7 expression in dorsal root ganglion (DRG) neurons innervating injured discs. This study aimed to examine ...
Rats with implanted telemetry transponders were blood sampled by jugular puncture, periorbital puncture or tail vein puncture, or sampled by jugular puncture in carbon dioxide (CO2), isoflurane or without anaesthesia in a crossover design. Heart rate, blood pressure and body temperature were registered for three days after sampling. Initially blood pressure increased, but shortly after sampling...
Hospital Physician June 2007 51 Lumbar puncture is a common procedure performed for diagnostic, anesthetic, and obstetric purposes; however, up to one third of patients may experience headache after the procedure.1,2 In 1898, Bier was the first to report on post–lumbar puncture headache (PLPH) after he and his associates underwent lumbar puncture themselves and experienced headaches first-hand....
A 29-year-old woman presented with dilated epidural veins and incapacitating headache after undergoing a lumbar puncture. Two months later, the results of follow-up MR imaging were normal. These findings suggest that temporary dilation of the epidural vein may occur in association with post-lumbar puncture intracranial hypotension syndrome. In these cases, it seems useful to confirm whether the...
