Paraplegia Caused by Spontaneous Spinal Hemorrhage in a Patient Undergoing Rivaroxaban Therapy.

BACKGROUND Spinal hematomas can be post-traumatic, iatrogenic, or spontaneous. A spontaneous spinal hematoma is a rare finding, but one with very serious clinical implications. There are some risk factors linked to its occurrence, e.g. arteriovenous malformations, lumbar puncture, coagulopathy, neoplasms, or therapeutic anticoagulation. At present, only a few cases of spontaneous spinal hematoma (SSH) associated with new oral anticoagulants (NOACs) have been described, three of which were linked with rivaroxaban. CASE REPORT We report the case of an 82-year-old Caucasian woman with persistent atrial fibrillation treated with rivaroxaban, who presented to the Urology Department with acute-onset back pain which was thought to be due to urolithiasis. No kidney stones were found, but her creatinine serum level was elevated, so she was transferred to our clinic for further treatment. During hospitalization she quickly developed paraplegia with urine and stool retention. MRI was performed, and demonstrated an acute epidural hemorrhage in her thoracic and lumbar spine. The neurosurgeons disqualified this patient from surgical intervention due to the extent of the hematoma and its location. The patient was referred to the Neurology Department for treatment and rehabilitation, but, to the best of our knowledge, she did not recover her motor function. CONCLUSIONS Although rivaroxaban has been shown to be more effective than warfarin in stroke prevention in patients with atrial fibrillation, physicians must remember that its use also carries the risk of major bleeding. SSH occurrence should be taken into account in a patient taking NOACs who develops paraplegia, even if there is no history of trauma prior to admission.

A Case Report: An Acute Spinal Epidural Hematoma after Acupuncture Mimicking Stroke.

BACKGROUND: Spinal epidural hematoma (SEH) after acupuncture is rare and may present with acute or subacute onset and varied symptoms, making it difficult to diagnose. This condition can mimic acute stroke, so it is vital to establish a clear diagnosis before considering thrombolytic therapy, which could be disastrous if applied inappropriately. CASE REPORT: We describe a 52-year-old man who presented to our emergency department (ED) with acute onset of unilateral weakness of the limbs for 3.5 h immediately after receiving acupuncture at the bilateral neck and back. The acute stroke team was activated. In the ED, computer tomography angiography from the aortic arch to the head revealed spinal epidural hematoma. The patient was admitted to the ward for conservative treatment and was discharged with subtle residual symptoms of arm soreness 5 days later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute spinal epidural hematoma rarely presents with unilateral weakness of the limbs, mimicking a stroke. Because inappropriate thrombolysis can lead to devastating symptoms, spinal epidural hematoma should be excluded when evaluating an acute stroke patient with a history of acupuncture who is a possible candidate for thrombolytic therapy.

Cervical epidural hematoma following interlaminar epidural steroid injection via the contralateral oblique view in patient taking omega-3 fatty acids.

BACKGROUND AND OBJECTIVES: We sought to describe a case of an epidural hematoma after a cervical interlaminar epidural steroid injection (ILESI) performed using contralateral oblique view. We also discuss factors that could have placed this patient at increased risk, including concurrent use of omega-3 fatty acids and non-steroidal anti-inflammatory medications. CASE REPORT: A 74-year-old woman returned to the pain clinic, within 15 min of discharge, after an apparent uncomplicated cervical ILESI using the contralateral oblique technique with severe periscapular pain and muscle spasms. Cervical MRI showed a large epidural hematoma which was subsequently emergently evacuated. On postoperative examination, the patient had no neurologic deficits and full resolution of her painful symptoms. CONCLUSIONS: To our knowledge, this is the first reported case of cervical epidural hematoma in which the contralateral oblique technique was used. Also, this is the second case in which the combination of non-steroidal anti-inflammatory medications and omega-3 fatty acids has been considered as a contributor to increased hematoma risk. This case underscores the risk of epidural hematoma using a novel fluoroscopic technique and the need for potential discontinuation of supplements like omega-3 fatty acids.

Massage-induced spinal epidural hematoma presenting with delayed paraplegia.

BACKGROUND: Spinal epidural hematoma (SEH) is an uncommon but serious emergency condition rare cases of spontaneously or following a minor traumatic event without bony injury. OBJECTIVE: We report the rare case of SEH associated with traditional massage initially presenting with delayed lower paraplegia. CASE REPORT: A 20-year-old man presented with bilateral lower extremity weakness and numbness 3 h prior to presentation. 3 days prior he was given a layperson Thai massage by a friend. Magnetic resonance imaging revealed a spinal epidural lesion suspicious for hematoma extending from C6 to T2 levels. Emergent surgical intervention for cord decompression was performed. An epidural hematoma with cord compression at C6-T2 levels was identified intraoperatively. No evidence of abnormal vascular flow or AV malformations was identified. Similar to chiropractic manipulation, massage may be associated with spinal trauma. CONCLUSION: Emergency physicians must maintain a high index of suspicion for spinal epidural hematomas in patients with a history of massage or chiropractic manipulation with neurologic complaints, because delays in diagnosis may worsen clinical outcome.

Acute Spinal Epidural Hematoma as a Complication of Dry Needling: A Case Report.

Dry needling is a procedure commonly performed for the relief of myofascial pain disorders. The procedure is generally well tolerated. Adverse events often are mild, but severe complications have been reported. This case report describes an acute spinal epidural hematoma as a complication of dry needling. It is a reminder to the performing physician or therapist to take specific precautions when placing a needle near the spine. Sudden onset of neuropathic pain after needling therapy in and around the spine should prompt emergency assessment with possibly advanced spine imaging to evaluate the integrity of the spinal cord. LEVEL OF EVIDENCE: V.

Spontaneous spinal epidural hematoma of the thoracic spine after herbal medicine: a case report.

BACKGROUND: Spontaneous spinal epidural hematoma (SSEH) is an uncommon disease, but it can lead to acute cord compression with disabling consequences. Identifiable reasons for spontaneous hemorrhage are vascular malformations and bleeding disorders. However, SSEH after taking herbal medicines has not been described yet. CASE PRESENTATION: A 60-year-old female experienced sudden back pain combined with numbness and weakness in the lower limbs for several hours with no trauma, drug use, family history or any disease history. Her deep tendon reflexes were normoactive, and Babinski was negative. An emergent MRI showed a spinal epidural hematoma extending from T3 to T5. She was taken to surgery after immediate clinical and laboratory evaluations had been completed. Emergency decompression with laminectomy was performed and the patient recovered immediately after the surgery. Additional history taken from the patient at outpatient clinic after discharge revealed that she had been continuously taking herbal medicine containing black garlic for 8 weeks. CONCLUSION: To our knowledge, no report has been previously issued on SSEH after taking herbal medicines. Although contradictory evidence is present on bleeding risks with herbal uses, we believe that it's reasonable to ascertain if patients with SSEP are taking herbal medication before or during spinal surgery.

Nerve root injection cancellations because of incomplete anticoagulation management.

BACKGROUND: Computed tomography-guided steroid injection is a well-recognized, conservative treatment of localized spinal pain as a result of facet arthropathy and radiculopathy secondary to nerve root compression. An extremely rare complication is the development of an epidural haematoma with potential to cause permanent neurological damage, so anticoagulation at the time of procedure is contraindicated. Routinely injections are performed as an outpatient requiring the referring physician to implement a peri-procedural anticoagulation plan. Anecdotal experience suggested that cancellations were occurring as patients remained on anticoagulation at the time of their appointment. The authors therefore assessed the existing service against expected standards to identify the causes of cancellations and find ways to improve the service. AIMS: This audit aimed to identify the incidence of cancelled computed tomography-guided nerve root injections secondary to incorrect peri-procedural anticoagulation management, develop an intervention to help reduce the incidence of cancellations and then re-audit to assess the effect of the intervention. METHODS: The audit standard was that 100% of outpatients attending for computed tomography-guided nerve root and facet injections should have an appropriate anticoagulation plan implemented. Baseline data collection took place prospectively between 1 September and 30 November 2016. The study population was elective computed tomography-guided spinal nerve root and facet injections scheduled on the radiology information system at the authors' trust. Descriptive analysis was completed. The intervention involved a revised electronic request form being implemented with new compulsory fields concerning antiplatelets and anticoagulants. Re-audit post-intervention involved prospective data collection between 1 September and 30 November 2017 using the same methods. RESULTS: Baseline audit found that of three out of 55 (5%) patients had cancellations. On re-audit, there were 0 cancellations out of 93 patients. CONCLUSIONS: The new request form prevented 5% of patients referred for computed tomography-guided nerve root injection being cancelled because of incorrect anticoagulation management. Extrapolated over the year the potential savings through preventing lost activity are £3445.56.

Cervical Epidural Hematoma That Induced Sudden Paraparesis After Cervical Spine Massage: Case Report and Literature Review.

BACKGROUND: Most people understand spinal manipulation therapy to be a safe procedure, and in many cases treatment is provided without a diagnosis if there is musculoskeletal pain. Cervical epidural hematoma occurs in extremely rare cases after cervical manipulation therapy. This study reports a case of epidural hematoma that occurred in the anterior spinal cord after cervical massage. CASE DESCRIPTION: A 38-year-old male patient was admitted to the emergency department for sudden weakness in the lower extremity after receiving a cervical spine massage. No fracture was found using cervical radiographs, and there were no particular findings on performing brain computed tomography or diffusion magnetic resonance imaging. However, using cervical magnetic resonance imaging, an acute epidural hematoma was observed in the anterior spinal cord from the C6 and C7 vertebrae to the T1 vertebra, compressing the spinal cord. There were no fractures or ligament injury. No surgical treatment was required as the patient showed spontaneous improvements in muscle strength and was discharged after just 1 week, following observation of the improvement in his symptoms. CONCLUSION: Although cervical epidural hematoma after cervical manipulation therapy is extremely rare, if suspected, a thorough examination must be performed in order to reduce the chances of serious neurologic sequelae.

Cerebrospinal vascular diseases misdiagnosed as decompression illness: the importance of considering other neurological diagnoses.

The diagnosis of decompression illness (DCI), which is based on a history of decompression and clinical findings, can sometimes be confounded with other vascular events of the central nervous system. The authors report three cases of divers who were urgently transported to a hyperbaric facility for hyperbaric oxygen treatment of DCI which at admission turned out to be something else. The first case, a 45-year-old experienced diver with unconsciousness, was clinically diagnosed as having experienced subarachnoid hemorrhage, which was confirmed by CT scan. The second case, a 49-year-old fisherman with a hemiparesis which occurred during diving, was diagnosed as cerebral stroke, resulting in putaminal hemorrhage. The third case, a 54-year-old fisherman with sensory numbness, ataxic gait and urinary retention following sudden post-dive onset of upper back pain, was diagnosed as spinal epidural hematoma; he also showed blood collection in the spinal canal. Neurological insults following scuba diving can present clinically with confusing features of cerebral and/or spinal DCI. We emphasize the importance of considering cerebral and/or spinal vascular diseases as unusual causes of neurological deficits after or during diving.

Acute Spinal Epidural Hematoma After Acupuncture: Personal Case and Literature Review.

BACKGROUND: Spinal acupuncture is a relatively safe and common analgesic treatment, but it may be complicated by serious adverse effects, such as direct spinal cord and nerve root injury, subdural empyema, and epidural abscesses. In this report we compare our case of an extremely uncommon spinal epidural hematoma, which appeared after treatment by acupuncture, with other similar documented cases. CASE DESCRIPTION: This is the case of a 64-year-old man who presented a left hemiparesis associated with paraesthesia. This appeared several hours after acupuncture treatment for left lumbosciatic pain. The cervicothoracic spine magnetic resonance imaging (MRI) scan showed a cervicothoracic spinal epidural hematoma from C2 to T12. The rapid improvement of the patient's neurologic symptoms justified the adoption of a conservative treatment strategy. This gave excellent long-term results. CONCLUSIONS: Although a post-acupuncture spinal epidural hematoma (paSEH) is very rare, there are only 6 documented cases, it is a possible complication from acupuncture on the back. The use of very thin needles can produce bleeding, probably venous, in the epidural space. In general, this evolves more slowly than other kinds of epidural hematomas. The symptoms are also less severe, warranting less frequent surgical intervention, and in general there is a good outcome. The possibility of hematoma makes acupuncture contraindicated in patients who have coagulation disorders. The onset of severe spinal pain after spinal or paraspinal acupuncture treatment should lead to the suspicion of a paSEH, and a spinal MRI should be carried out.

The Risks of Continuing or Discontinuing Anticoagulants for Patients Undergoing Common Interventional Pain Procedures.

Background: Guidelines have been published that recommend discontinuing anticoagulants in patients undergoing interventional pain procedures. The safety and effectiveness of these guidelines have not been tested. Objectives: The present study was performed to determine if continuing or discontinuing anticoagulants for pain procedures is associated with a detectable risk of complications. Methods: An observational study was conducted in a private practice in which some partners continued anticoagulants while other partners routinely discontinued anticoagulants. Results: No complications attributable to anticoagulants were encountered in 4,766 procedures in which anticoagulants were continued. In 2,296 procedures in which anticoagulants were discontinued according to the guidelines, nine patients suffered serious morbidity, including two deaths. Conclusions: Lumbar transforaminal injections, lumbar medial branch blocks, trigger point injections, and sacroiliac joint blocks appear to be safe in patients who continue anticoagulants. In patients who discontinue anticoagulants, although low (0.2%) the risk of serious complications is not zero, and must be considered when deciding between continuing and discontinuing anticoagulants.

Regional anesthesia practice in China: a survey.

STUDY OBJECTIVE: Neuraxial anesthesia has been widely used in China. Recently, Chinese anesthesiologists have applied nerve stimulator and ultrasound guidance for peripheral nerve blocks. Nationwide surveys about regional anesthesia practices in China are lacking. We surveyed Chinese anesthesiologists about regional anesthesia techniques, preference, drug selections, complications, and treatments. DESIGN: A survey was sent to all anesthesiologist members by WeChat. The respondents can choose mobile device or desktop to complete the survey. Each IP address is allowed to complete the survey once. MAIN RESULTS: A total of 6589 members read invitations. A total of 2654 responses were received with fully completed questionnaires, which represented an overall response rate of 40%. Forty-one percent of the respondents reported that more than 50% of surgeries in their hospitals were done under regional anesthesia. Most of the participants used test dose after epidural catheter insertion. The most common drug for test dose was 3-mL 1.5% lidocaine; 2.6% of the participants reported that they had treated a patient with epidural hematoma after neuraxial anesthesia. Most anesthesiologists (68.2%) performed peripheral nerve blocks as blind procedures based on the knowledge of anatomical landmarks. A majority of hospitals (80%) did not stock Intralipid; 61% of the respondents did not receive peripheral nerve block training. CONCLUSIONS: The current survey can serve as a benchmark for future comparisons and evaluation of regional anesthesia practices in China. This survey revealed potential regional anesthesia safety issues in China.
