BACKGROUND The level of sensory block in postoperative epidural analgesia has been correlated with conventional contrast epidurography in only one study, while low-dose CT scan epidurography with multiplanar reconstruction may be a better tool for this purpose. OBJECTIVES The primary objective of this study was to evaluate, by CT imaging and digital multiplanar reconstruction, the spread and ...

conclusions ct epidurography is not closely correlated with a clinical assessment of epidural block; thus, a clinical assessment of the sensory block is mandatory. the use of opioid analgesia in combination with local anesthetics may compensate for the lack of efficacy of local anesthetics alone. objectives the primary objective of this study was to evaluate, by ct imaging and digital multiplan...

The medical records of 156 dogs with degenerative lumbosacral stenosis (DLS) that underwent decompressive surgery were reviewed for signalment, history, clinical signs, imaging and surgical findings. The German Shepherd Dog (GSD) was most commonly affected (40/156, 25.6%). Pelvic limb lameness, caudal lumbar pain and pain evoked by lumbosacral pressure were the most frequent clinical findings. ...

Adjunct cervical CT epidurography (CCTE) can be used to image impingement in patients with cervical brachalgia undergoing fluoroscopic-guided cervical transforaminal injection (TFI) of steroid/local anaesthetic where magnetic resonance imaging (MRI) is contraindicated. CCTE images of the 9 patients on whom the authors performed CCTE post TFI over 6 years from 1998 to 2003 were retrospectively r...

BACKGROUND Anecdotal evidence suggests that a vertical small-needle injection method enters the caudal epidural space with comparable efficacy to cephalad-directed methods, with less intravascular injection. OBJECTIVES Assess the success rate of vertical caudal epidural injection using epidurography and the frequency of intravascular injection using a vertical small-needle approach. PATIENT...

In this issue of the AJNR, Johnson (no relation) et al (page 697) describe their experience with the use of fluoroscopy and epidurography in the placement of epidural steroids. The authors assert that the subarachnoid injection of corticosteroids is a serious complication that can be avoided with the use of epidurography. A series of 5334 outpatient epidural steroid injections were performed af...

BACKGROUND Thoracic epidural anesthesia is frequently used to maintain intraoperative and postoperative analgesia. Frequently, 3 ml of local anesthetic is used as a test dose, or for intermittent epidural injection. We assessed the extent of the spread of 3 ml of contrast medium in the thoracic epidural space and attempted to identify any correlating factors affecting the epidurography. METHO...
