We have evaluated the influence of speed of intrathecal injection on lateral distribution of 0.5% hyperbaric bupivacaine. We studied 60 patients undergoing lower limb surgery who were placed in the lateral position with the operative side in the dependent position. After dural puncture (25-gauge Whitacre spinal needle), the needle aperture was turned towards the dependent side and 0.5% hyperbar...

We report two cases of Caesarean section in patients with Marfan's syndrome where continuous subarachnoid anaesthesia failed to provide an adequate surgical block. This was possibly because of dural ectasia, which was confirmed by a computed tomography scan in both cases.

PURPOSE OF REVIEW Regional analgesia for labor pain and general anesthesia for cesarean section in the morbidly obese parturient is associated with increased maternal and perinatal complications. The purpose of this review is to describe the anesthetic management of the morbidly obese parturient. RECENT FINDINGS Compared to the lean parturient, the morbidly obese parturient has an increased l...

BACKGROUND Epidrum® is a recently developed, air operated, loss of resistance (LOR) device for identifying the epidural space. We investigated the usefulness of Epidrum® by comparing it with the conventional LOR technique for identifying the epidural space. METHODS One hundred eight American Society of Anesthesiologists (ASA) physical status I or II patients between the ages of 17 and 68 year...

Acute cerebral sinus thrombosis caused a patient to decompensate rapidly and required immediate relief of her venous thrombosis as a life-saving procedure. The thrombus was laced with urokinase and removed from the sinuses with thrombectomy catheters. This reinstituted flow and she recovered full neurologic function within 4 hours.

Cerebral venous and dural sinus thrombosis (CVT) is a rare condition with a wide spectrum of clinical presentations. The epidemiology of the disease has evolved considerably during the recent decades with increasing oral contraceptive use in young and middle-aged women. CVT has various causes including genetic and acquired prothrombotic disorders and it usually has a favorable outcome with a lo...

Behcet disease is a rare multi-system immune related vasculitis which may involve the central nervous system, usually during the course of the illness. Magnetic resonance imaging is currently the modality of choice for the detection of the parenchymal lesions in their different phases, as well as the dural sinus venous thrombosis.

Objective To compare posterior lumbar interbody fusion (PLIF) with transforaminal lumbar interbody fusion (TLIF) for spinal fusion in patients previously treated by discectomy. Methods This retrospective study evaluated pre- and postoperative neurological status via Japan Orthopaedic Association (JOA) score. Surgical outcome was based on recovery rate percentage (RR%). Adverse event data were r...

As long ago as 1876 Key and Retzius suggested that the canal of Schlemm was like a dural venous sinus, and Rochon-Duvigneaud (1892) was insistent on this point. Also, Wegefarth (1914), in experiments on the cerebro-spinal fluid, which ran parallel with those ofWeed (1914), showed that Pacchionianlike bodies occurred in Schlemm's canal in cats, dogs, rabbits, and monkeys. Since, however, this wa...

Although MR imaging is being used increasingly to detect dural sinus thrombosis, accurate evaluation of images has often been hindered by the presence of artifacts, especially flow-related enhancement, that may simulate intraluminal clot. We tried an approach with spin-echo techniques to eliminate flow-induced artifacts and, thus, facilitate the diagnosis of dural sinus thrombosis. In this inve...
