Dissociative paraplegia after epidural anesthesia: a case report

Abdominal Pain Associated With Anorexia Nervosa and Median Arcuate Ligament Syndrome: A Rare Condition Shadowed by a Postoperative Conversion Disorder

Median arcuate ligament syndrome (MALS) is an often discounted and vexing condition that may go unnoticed in a population of patients with complex comorbid conditions or those with poor psychiatric health. We report a unique case of a patient with anorexia nervosa in whom the successful operation for MALS was briefly complicated by a postoperative conversion disorder.

Surgical treatment of a broken neuroplasty catheter in the epidural space: a case report

Background

Percutaneous epidural neuroplasty with a Racz catheter is widely used to treat radicular pain caused by spinal stenosis or a herniated intervertebral disc. The breakage or shearing of an epidural catheter, particularly a percutaneous epidural neuroplasty catheter, is reported as a rare complication. There has been a controversy over whether surgical removal of a shorn epidural catheter is needed. Until now, only three cases related to sheared Racz neuroplasty catheters have been reported. We report a case of a neuroplasty catheter which completely broke when it was inserted into the epidural space, and compressed root symptoms were exacerbated by the broken catheter.

Case presentation

A 68-year-old Asian man with leg pain and lower back pain caused by lumbar vertebral body 4 to lumbar vertebral body 5 intervertebral disc herniation and stenosis underwent percutaneous epidural neuroplasty. During the procedure, the epidural neuroplasty catheter was trapped in the left foraminal portion and broke. Our patient complained of left-side leg pain and numbness. Surgery performed to remove the broken catheter led to complete resolution of his leg pain and numbness.

Conclusions

We report a rare case of catheter breakage occurring during epidural neuroplasty. We suggest surgical removal because the implanted catheter can aggravate a patient’s symptoms and lead to the development of neurologic deficits due to infection, fibrosis, or mechanical neural irritation.

A clinically oriented perspective on psychogenic nonepileptic seizure-related emergencies

Psychogenic nonepileptic seizures (PNES) can present emergently and are often mistaken for epileptic seizures. PNES emergencies have not been well studied, and yet there are associated serious morbidities, particularly when patients are seen in an emergency setting and are misdiagnosed. PNES may be prolonged, mimicking status epilepticus, a condition we refer to as nonepileptic psychogenic status (NEPS), and patients may receive aggressive and unnecessary medical treatments that can lead to serious iatrogenic complications, including death. NEPS is also associated with an increased risk of self-harm, including suicide attempts, and may indicate a serious comorbid psychiatric illness. In addition to iatrogenic complications of PNES, accidents and injuries are an underrecognized source of morbidity. PNES may also present during medical procedures, which may not only interfere with their completion, but may alarm practitioners who, fearing liability, may initiate further medical evaluations and treatments. When PNES occur during pregnancy, patients may be misdiagnosed with eclampsia and their offspring delivered prematurely. They also risk being placed on medications that are harmful to the fetus. Increased awareness of PNES is necessary to prevent iatrogenic harm and to identify underlying psychiatric illnesses that carry their own risks. As yet, data available to guide treatment are scant, and further study is needed.
