1/6. Foraminal injection of a painful sacral nerve root using an epidural catheter: case report.BACKGROUND AND OBJECTIVES: Nerve root pain has been treated with steroid injections since the 1970s. We will describe a novel method for nerve root injection using a directed epidural catheter. CASE REPORT: A case is described where catheter placement accurately reproduced symptoms which were then relieved with local anesthetic and steroid. CONCLUSION: This is a novel approach to treatment of painful nerve roots with a catheter.- - - - - - - - - - ranking = 1keywords = catheter (Clic here for more details about this article) |
2/6. radiation myelitis in a 5-year-old girl.Myelopathy is an uncommon complication of radiotherapy, particularly in the pediatric age group. A 5-year-old girl with acute lymphoblastic leukemia developed a severe but transient radiculopathy after intrathecal administration of methotrexate and cytarabine for an isolated central nervous system relapse. Chemotherapy was then given through an intraventricular catheter. Owing to a second central nervous system recurrence, she was treated with craniospinal radiation. The whole brain down to the level of C2 received a dose of 2400 cGy. Two months after completion of radiation, the child developed a progressive tetraparesis, and magnetic resonance imaging revealed an enhancing lesion involving the medulla and upper cervical cord. A biopsy was consistent with a treatment-related necrotizing leukoencephalopathy. This case suggests that patients who develop neurologic dysfunction when treated with methotrexate can also be particularly susceptible to radiation-related injury.- - - - - - - - - - ranking = 0.14285714285714keywords = catheter (Clic here for more details about this article) |
3/6. Diabetic thoracic radiculopathy: an unusual cause of post-thoracotomy pain.Persistent pain is common following thoracotomy. A 64-year-old retired electrician with Type 2 diabetes presented with chest wall and abdominal pain 3 months following video-assisted thoracoscopic surgery (VATS). Postoperatively the patient had suffered pain despite a functioning thoracic epidural catheter. Following investigation, his persistent pain was due to diabetic thoracic radiculopathy (DTR). The disorder is characterized by pain, sensory loss, abdominal and thoracic muscle weakness in patients with diabetes. As in this patient, the pain and sensory loss usually resolve within one year after onset. The disorder may be distinguished from intercostal neuralgia based upon clinical and electromyographic features.- - - - - - - - - - ranking = 0.14285714285714keywords = catheter (Clic here for more details about this article) |
4/6. Intradural migration of broken IDET catheter causing a radiculopathy.This case report describes the migration of a broken intradiscal electrothermal therapy catheter tip from the disc space into the thecal sac, leading to a radiculopathy that improved after removing the catheter.- - - - - - - - - - ranking = 0.85714285714286keywords = catheter (Clic here for more details about this article) |
5/6. Cervical radiculopathy due to intra-arterial infusion of cisplatin.A 55-year-old man with cervical radiculopathy (C5-C8) was referred to us following intra-arterial infusion of cisplatin (CDDP) because of a recurrent neck mass of laryngeal cancer. Three hours after the CDDP infusion, he had noticed general weakness of the left upper extremity and hypoaesthesia of the lateral side of the upper and lower arm. The next day he was diagnosed with left cervical radiculopathy of C5 to C8, which improved gradually and had resolved completely six months after the infusion. Even with proper positioning of the infusion catheter to minimize potential complications, for anatomical reasons there are always some risks of neural injury with intra-arterial infusion from branches of the subclavian artery. This procedure should be carefully indicated in the case of a large neck tumour that is perfused from the major branches of the subclavian artery.- - - - - - - - - - ranking = 0.14285714285714keywords = catheter (Clic here for more details about this article) |
6/6. Retention of urine and sacral paraesthesia in anogenital herpes simplex infection.Two definite and 2 probable cases of anogenital herpes simplex and sacral radiculitis are described. Symptoms were typical and consisted of paraesthesia and neuralgic pain in the perineum and legs, urinary retention and constipation occurring within several days to a week after an anogenital herpetic eruption. However, at presentation only 1 case had an obvious history of anogenital herpes simplex. Neurological signs were not striking and consisted of a reduced appreciation of light touch and pin prick over the sacral dermatomes and in 2 cases reduced anal sphincter tone. CSF examination in 3 patients showed a lymphocytosis. Bladder catheterisation was required for up to 2 weeks in 2 patients. The paraesthesia persisted for weeks to months. It should be more widely recognised that anogenital herpes simplex, with sacral radiculitis, is probably the commonest cause of acute retention of urine in young sexually active people.- - - - - - - - - - ranking = 0.14285714285714keywords = catheter (Clic here for more details about this article) |
