1/22. Nontraumatic acute spinal subdural hematoma: report of five cases and review of the literature.Acute subdural spinal hematoma occurs rarely; however, when it does occur, it may have disastrous consequences. The authors assessed the outcome of surgery for this lesion in relation to causative factors and diagnostic imaging (computerized tomography [CT], CT myelography), as well as eventual preservation of the subarachnoid space. The authors reviewed 106 cases of nontraumatic acute subdural spinal hematoma (101 published cases and five of their own) in terms of cause, diagnosis, treatment, and long-term outcome. Fifty-one patients (49%) were men and 55 (51%) were women. In 70% of patients the spinal segment involved was in the lumbar or thoracolumbar spine. In 57 cases (54%) there was a defect in the hemostatic mechanism. spinal puncture was performed in 50 patients (47%). Late surgical treatment was performed in 59 cases (56%): outcome was good in 25 cases (42%) (in 20 of these patients preoperative neurological evaluation had shown mild deficits or paraparesis, and three patients had presented with subarachnoid hemorrhage [SAH]). The outcome was poor in 34 cases (58%; 23 patients with paraplegia and 11 with SAH). The formation of nontraumatic acute spinal subdural hematomas may result from coagulation abnormalities and iatrogenic causes such as spinal puncture. Their effect on the spinal cord and/or nerve roots may be limited to a mere compressive mechanism when the subarachnoid space is preserved and the hematoma is confined between the dura and the arachnoid. It seems likely that the theory regarding the opening of the dural compartment, verified at the cerebral level, is applicable to the spinal level too. Early surgical treatment is always indicated when the patient's neurological status progressively deteriorates. The best results can be obtained in patients who do not experience SAH. In a few selected patients in whom neurological impairment is minimal, conservative treatment is possible.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
2/22. spinal cord injury following an attempted thoracic epidural.Unsuccessful attempts were made to insert a thoracic epidural in an anaesthetised patient. Signs of spinal cord damage were observed the following day. magnetic resonance imaging demonstrated a haematoma anterior to the spinal cord. Surgical exploration revealed an intradural haematoma and a needle puncture of the cord. The patient suffered a permanent paraparesis.- - - - - - - - - - ranking = 0.5keywords = puncture (Clic here for more details about this article) |
3/22. Spontaneous spinal epidural abscess in a neonate. With a review of the literature.Spinal epidural abscess is uncommon in neonates and infants, and is usually related to previous lumbar puncture or epidural anaesthesia. diagnosis is often delayed because of the non-specific presentation. We present a 7-week-old girl who developed paraplegia 3 weeks after transient fever and a self-limiting skin rash. MR imaging revealed an epidural contrast-enhancing lesion compressing the spinal cord. At operation, an organised granulated abscess was identified with staphylococcus aureus the causative organism. laminectomy and removal of the organised abscess and systemic intravenous antibiotics resulted in complete neurological recovery. The patient did not develop late spinal deformity following the decompressive laminectomy. The rapid onset of paraplegia can often be missed in such a young child but should be promptly investigated, as surgical treatment of cord compression carries an excellent prognosis for neurological recovery. We review the literature on the initial presentation, usual investigations, causative organisms and surgical management of paediatric spinal epidural abscesses.- - - - - - - - - - ranking = 0.5keywords = puncture (Clic here for more details about this article) |
4/22. Persistent paraplegia after an aqueous 7.5% phenol solution to the anterior motor root for intercostal neurolysis: a case report.A 55-year-old white man with severe scoliosis and chest deformity was scheduled for an intercostal neurolysis for pain relief with 7.5% aqueous phenol solution. A 20 G needle was inserted 3 to 4cm lateral to the midline of the spine under the 10th right rib. After negative aspiration for blood and alcohol, 6mL of a 7.5% aqueous phenol solution was injected. Within a minute after the injection, the patient felt a warm sensation in his right leg, followed by loss of leg motor and sensory function on both sides. A lumbar puncture done 3.5 hours after the block showed a phenol concentration of 87.5 microg/mL. The most likely explanation is a diffusion of the phenol through the intervertebral foraminae reaching the spinal space and therefore damaging the motor and sensory roots. This case highlights the danger associated with phenol application in the vicinity of the spinal cord.- - - - - - - - - - ranking = 0.5keywords = puncture (Clic here for more details about this article) |
5/22. Post lumbar puncture spinal subarachnoid hematoma causing paraplegia: a short report.A 53 year old male underwent total excision of a large sphenoidal wing meningioma. Patient was treated with cephalosporins and phenytoin for postoperative meningitis. Three weeks after surgery, a follow up lumbar puncture was done. The patient became paraplegic over a few hours. Imaging of the dorsolumbar spine and other investigations demonstrated a large intraspinal hematoma caused by thrombocytopenia which was probably drug induced. After normalising the platelet count surgical evacuation of the spinal subarachnoid hematoma was done. Relevant literature is reviewed.- - - - - - - - - - ranking = 2.5keywords = puncture (Clic here for more details about this article) |
6/22. A case of anterior interosseous nerve syndrome after peripherally inserted central catheter (PICC) line insertion.Palsies involving the anterior interosseous nerve comprise less than 1% of all upper extremity nerve palsies. patients often present initially with acute pain in the proximal forearm, lasting several hours to days. The pain subsides, to be followed by paresis or total paralysis of the pronator quadratus, flexor pollicis longus and the radial half of the flexor profundus, either individually or together. patients with a complete lesion will have a characteristic pinch deformity. We report a case of anterior interosseous syndrome in a 42-year-old male. The patient was admitted initially for chronic osteomyelitis of the left calcaneum. He had a peripherally inserted central catheter (PICC) line inserted into a brachial vein for the administration of intravenous antibiotics, and developed anterior interosseous nerve palsy as a complication of this procedure. The catheter was subsequently removed and a new line was placed on the other side, and his neurological deficit has been improving since. This case highlights the potential hazards of venupuncture or arterial puncture of the brachial vein or artery respectively, even under controlled conditions with the benefit of ultrasound guidance. It also serves as a reminder to look out for the complications of these common procedures, and to be able to react appropriately when they arise.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
7/22. Intramedullary hemorrhage in a neonate after lumbar puncture resulting in paraplegia: a case report.We present the case of a premature infant with decreased spontaneous movement of the lower extremities. Imaging was demonstrative of a lesion of the conus medullaris. Operatively and with histologic confirmation, the mass was determined to be a blood clot originating from the conus. Retrospectively, the patient had a known lumbar puncture. There were no clotting abnormalities in this patient. At long-term follow-up, the child continues to have lower extremity paresis and incontinence of bowel and bladder. Clinicians should consider the lower termination of the conus medullaris in the infant, especially in the preterm infant.- - - - - - - - - - ranking = 2.5keywords = puncture (Clic here for more details about this article) |
8/22. Paraneoplastic myelopathy at diagnosis in a patient with pathologic stage 1A hodgkin disease.The case of a patient with pathologic Stage 1A hodgkin disease is reported in whom subacute paraneoplastic myelopathy developed before treatment. myelography, computed tomography, magnetic resonance imaging, and lumbar puncture examination showed no evidence of central nervous system involvement. The patient was treated with combination chemotherapy (to avoid spinal cord exposure to radiation) without neurologic improvement. The patient's neurologic condition responded well to intrathecal dexamethasone.- - - - - - - - - - ranking = 0.5keywords = puncture (Clic here for more details about this article) |
9/22. Spontaneous spinal hematomas and low-molecular-weight heparin. Report of four cases and review of the literature.The purpose of this article is to raise awareness of spontaneous spinal hematomas that develop after administration of low-molecular-weight heparin therapy. The authors describe four patients in whom these hematomas developed without precipitating events while receiving a treatment dose of enoxaparin (Clexane) (approximately 1 mg/kg). Spontaneous spinal hematomas (not related to trauma, surgery, or lumbar puncture) are a rare clinical entity. Several causes have been identified, including acquired and congenital clotting abnormalities and underlying vascular lesions. aspirin, warfarin, tissue plasminogen activator, and heparin have all been implicated in causing spinal hematomas. Concerns regarding the use of low-molecular-weight heparin agents in neuraxis anesthesia have been well documented. Their possible contribution to nontraumatic spinal hematomas has been less well described. The authors believe that low-molecular-weight heparin agents present a small but significant risk of spinal hematoma. This should be considered when prescribing therapy because such a complication may be catastrophic.- - - - - - - - - - ranking = 0.5keywords = puncture (Clic here for more details about this article) |
10/22. Occult epidural chloroma complicated by acute paraplegia following lumbar puncture.Acute paraplegia complicating lumbar puncture in a leukemic patient with an unsuspected epidural chloroma is described, including the postmortem findings. Lumbar puncture can precipitate irreversible injury to the spinal cord in the patient with an occult lesion causing subarachnoid block. This account, in addition to documenting this phenomenon, suggests a potential advantage to magnetic resonance imaging over myelography.- - - - - - - - - - ranking = 3keywords = puncture (Clic here for more details about this article) |
