RESUMEN

PURPOSE: Spontaneous spinal hematoma (SSH), a rare neurological disorder, demands immediate diagnostic evaluation and intervention to prevent lasting deficits. This case series analyzes instances, particularly highlighting cases where vascular causes were identified despite inconclusive initial imaging. METHODS: In a retrospective study of 20 patients treated for SSH at a Level I spine center from 01/01/2017 to 11/15/2023, we examined demographics, clinical presentation, imaging, and treatment details. Excluding traumatic cases, we present 4 instances of SSH associated with diverse vascular pathologies. RESULTS: Patient ages ranged from 39 to 85 years, with a median age of 66 years. 45% were male, and 55% were female. Among 20 cases, 14 were epidural hematomas, 4 subdural, 1 combined epidural and subdural, and 1 subarachnoid hemorrhage. 85% presented with neurological deficits, while 3 solely had pain-related symptoms. 55% were under anticoagulant medication, and vascular anomalies were found in 25% of cases. The cause of SSH remained unclear in 20% of cases. MRI was performed for all patients, and DSA was conducted in 25% of cases. The 4 highlighted cases involved individuals with distinct vascular pathologies managed surgically. CONCLUSION: Urgent attention is crucial for SSH due to possible lasting neurological consequences. The study emphasizes comprehensive diagnostics and surgical exploration, especially in cases with unclear etiology, to identify and address vascular causes, preventing hematoma progression or recurrence. Despite their rarity, vascular malformations contributing to spinal hematomas warrant particular attention.

RESUMEN

Bleeding diathesis is an uncommon side effect of ibrutinib use and is seen in less than 5% of the population. We describe a case of an elderly woman with ibrutinib-induced spontaneous major extradural haematoma presenting as acute compressive myelopathy. She is a known case of splenic marginal zone lymphoma with multiple extramedullary relapses and presented to the emergency department with acute-onset low backache, followed by urinary retention. MRI revealed extradural haemorrhage. After possible evaluation, she was diagnosed with ibrutinib-induced extradural haematoma.

RESUMEN

BACKGROUND: Delayed spinal epidural hematoma (SEH) following central neuraxial block (CNB) is a rare but serious complication. The underlying causes of SEH associated with neuraxial anesthesia are still unclear. Furthermore, the decision between surgical intervention and conservative management for SEH remains a complex and unresolved issue. CASE PRESENTATION: We report a case of delayed SEH in a 73-year-old woman who underwent vaginal hysterectomy under combined spinal-epidural anesthesia, with the administration of postoperative anticoagulants to prevent deep vein thrombosis on the 1st postoperative day (POD). She experienced symptoms 56 h after CNB. Magnetic resonance imaging (MRI) revealed a dorsal SEH at the L1-L4 level with compression of the thecal sac. On conservative treatment, full recovery was achieved after six months. CONCLUSIONS: This case reminds anesthesiologists should be alert to the possible occurrence of a delayed SEH following CNB, particularly with the administration of anticoagulants. Immediate neurological evaluation of neurological deficit and MRI are advised. Conservative treatment combined with close and dynamic neurological function monitoring may be feasible for patients with mild or nonprogressive symptoms even spontaneous recovery.

RESUMEN

PURPOSE: Spontaneous spinal epidural hematoma (SSEH) is a rare pathology characterized by a hemorrhage in the spinal epidural space without prior surgical or interventional procedure. Recent literature reported contradictory findings regarding the clinical, radiological and surgical factors determining the outcome, hence the objective of this retrospective analysis was to re-assess these outcome-determining factors. METHODS: Patients surgically treated for SSEH at our institution from 2010 - 2022 were screened and retrospectively assessed regarding management including the time-to-treatment, the pre-and post-treatment clinical status, the radiological findings as well as other patient-specific parameters. The outcome was assessed using the modified McCormick Scale. Statistical analyses included binary logistic regression and Fisher's exact test. RESULTS: In total, 26 patients (17 men [65%], 9 women [35%], median age 70 years [interquartile range 26.5]) were included for analysis. The SSEHs were located cervically in 31%, cervicothoracically in 42% and thoracically in 27%. Twenty-four patients (92%) improved after surgery. Fifteen patients (58%) had a postoperative modified McCormick Scale grade of I (no residual symptoms) and 8 patients (31%) had a grade of II (mild symptoms). Only 3 (12%) patients remained with a modified McCormick Scale grade of IV or V (severe motor deficits / paraplegic). Neither time-to-treatment, craniocaudal hematoma expansion, axial hematoma occupation of the spinal canal, anticoagulation or antiplatelet drugs, nor the preoperative clinical status were significantly associated with the patients' outcomes. CONCLUSION: Early surgical evacuation of SSEH generally leads to favorable clinical outcomes. Surgical hematoma evacuation should be indicated in all patients with symptomatic SSEH.

RESUMEN

PURPOSE: Spinal epidural hematoma (SEH) is a rare yet significant complication associated with neuraxial anesthesia. Here, we present the case of a 74-yr-old male who underwent open repair of an abdominal aortic aneurysm. Following the removal of an epidural catheter, the patient developed anterior spinal cord syndrome due to an SEH despite having a normal coagulation profile. CLINICAL FEATURES: This patient's neurologic presentation was marked by a loss of motor function while maintaining fine touch sensation distal to the spinal cord injury. Initial truncal computed tomography (CT) angiography failed to detect vascular compromise or diagnose the SEH. Subsequently, delayed magnetic resonance imaging (MRI) revealed a multilevel thoracic epidural hematoma, spinal cord infarction, and ischemia. Immediate surgical decompression was performed, but unfortunately, the patient had a poor outcome. CONCLUSION: Anterior spinal cord syndrome (ASCS) represents an uncommon neurologic manifestation of SEH, which is typically characterized by a triad of back pain and sensory and motor deficits. Although the initial CT scan was necessary to diagnose the postvascular surgery complication, it did not immediately detect the SEH. In cases of ASCS subsequent to thoracic epidural placement and removal, MRI is the preferred imaging modality for precise diagnosis and assessment of the need for surgical intervention. Despite adherence to anticoagulation guidelines, patients undergoing neuraxial anesthesia may face an elevated risk of developing SEH. Health care professionals should remain vigilant in monitoring for neurologic abnormalities following epidural catheter insertion or removal, particularly in the context of vascular surgery.

RéSUMé: OBJECTIF: L'hématome péridural rachidien est une complication rare mais importante associée à l'anesthésie neuraxiale. Nous présentons ici le cas d'un homme de 74 ans qui a bénéficié d'une réparation ouverte d'un anévrisme de l'aorte abdominale. Après le retrait d'un cathéter péridural, le patient a développé un syndrome médullaire antérieur dû à un hématome péridural rachidien malgré un profil de coagulation normal. CARACTéRISTIQUES CLINIQUES: La présentation neurologique de ce patient était marquée par une perte de la fonction motrice tout en conservant une sensation de toucher fine distale à la lésion médullaire. L'angiographie initiale par tomodensitométrie (TDM) n'a pas permis de détecter d'atteinte vasculaire ni de diagnostiquer un hématome péridural rachidien. Par la suite, une imagerie par résonance magnétique (IRM) retardée a révélé un hématome péridural thoracique à plusieurs niveaux, un infarctus médullaire et une ischémie. Une décompression chirurgicale immédiate a été réalisée, mais malheureusement, l'issue a été mauvaise pour le patient. CONCLUSION: Le syndrome médullaire antérieur représente une manifestation neurologique peu fréquente de l'hématome péridural rachidien, qui se caractérise généralement par une triade de maux de dos et de déficits sensoriels et moteurs. Bien que la tomodensitométrie initiale ait été nécessaire pour diagnostiquer la complication chirurgicale post-vasculaire, elle n'a pas immédiatement détecté l'hématome péridural rachidien. Dans les cas de syndromes médullaires antérieurs consécutifs à la pose et au retrait d'un cathéter péridural thoracique, l'IRM est la modalité d'imagerie privilégiée pour un diagnostic précis et une évaluation de la nécessité d'une intervention chirurgicale. Malgré le respect des directives d'anticoagulation, les patient·es bénéficiant d'une anesthésie neuraxiale peuvent faire face à un risque élevé de développer un hématome péridural rachidien. Les professionnel·les de la santé doivent demeurer vigilant·es dans le monitorage des anomalies neurologiques à la suite de l'insertion ou du retrait d'un cathéter péridural, en particulier dans le contexte d'une chirurgie vasculaire.

RESUMEN

PURPOSE: Mebos, a traditional South Africa confection consisting of dried, pulped, and sugared apricots, is rich in fibre and vitamins, but also contains salicylic acid, flavonoids, and citric acid. We report a case of postoperative surgical site bleeding in a healthy patient who consumed approximately 2 kg of mebos per day prior to his elective spinal surgery. METHODS: The clinical course of a previously healthy 54-year-old male patient with cauda equina syndrome secondary to lumbar spinal stenosis who underwent surgical intervention with subsequent bleeding into the surgical site is discussed. The cause was investigated through biochemical analysis, thromboelastometry (ROTEM®) and mass and absorption spectrometry were applied to assess flavonoid, citric acid, and salicylic acid content. RESULTS: ROTEM® revealed an abnormal clotting profile with an increased clot forming time, suggesting intrinsic coagulopathy. Mass and absorption spectrometry revealed a high total flavonoid content as well as citric acid concentration in the mebos. Salicylic acid was at detection limits of the instrument. CONCLUSION: Results highlighted the effect of flavonoids and citric acid and therefore explain the abnormal clotting profile in this patient. Inhibition of coagulation prior to elective surgery is a known contraindication and may pose great risks in spinal surgery. In the present report, we demonstrated an association between inhibition of coagulation and an excess of the flavonoids content and citric acid concentration in mebos consumed in the days prior to elective spinal surgery.

RESUMEN

Spontaneous spine epidural haematoma is a rare occurrence, with an incidence of 0.1/100 000 inhabitants/year. The anterior location of the haematoma is very uncommon since the dural sac is firmly attached to the posterior longitudinal ligament. Vertebral artery dissection as its underlying cause is an exceptionally rare event, with only two documented cases.This article presents the case of young woman who arrived at the emergency room with a spinal ventral epidural haematoma extending from C2 to T10, caused by a non-traumatic dissecting aneurysm of the right vertebral artery at V2-V3 segment. Since the patient was tetraparetic, she underwent emergent laminectomy, and the vertebral artery dissection was subsequently treated endovascularly with stenting.Vertebral artery dissection with subsequent perivascular haemorrhage is a possible cause of spontaneous spine epidural haematoma, particularly when located ventrally in the cervical and/or high thoracic column. Hence the importance of a thorough investigation of the vertebral artery integrity.

RESUMEN

PURPOSE: The purpose of this study was to establish an animal model capable of simulating the development and decompression process of symptomatic spinal epidural hematoma (SSEH). METHODS: A total of 16 male Bama miniature pigs were included in this study and randomly allocated into four groups: Group A (4 h 20 mmHg hematoma compression), Group B (4 h 24 mmHg hematoma compression), Group C (4 h 28 mmHg hematoma compression), and Group Sham (control). Real-time intra-wound hematoma compression values were obtained using the principle of connectors. Electrophysiological analyses, including the latency and amplitude of somatosensory evoked potentials (SSEP) and motor evoked potentials (MEP), along with behavioral observations (Tarlov score), were performed to assess this model. RESULTS: ANOVA tests demonstrated significant differences in the latency and relative amplitude of SSEP and MEP between Groups C and Sham after 4 h of hematoma compression and one month after surgery (P < 0.01). Behavioral assessments 8 h after surgery indicated that animals subjected to 28 mmHg hematoma compression suffered the most severe spinal cord injury. Pearson correlation coefficient test suggested a negative correlation between the epidural pressure and Tarlov score (r = -0.700, p < 0.001). With the progression of compression and the escalation of epidural pressure, the latency of SSEP and MEP gradually increased, while the relative amplitude gradually decreased. CONCLUSIONS: When the epidural pressure reaches approximately 24 mmHg, the spinal cord function occurs progressive dysfunction. Monitoring epidural pressure would be an effective approach to assist to identify the occurrence of postoperative SSEH.

RESUMEN

BACKGROUND: Spontaneous spinal hematoma (SSH) is a debilitating complication in patients taking either antiplatelet (AP) or anticoagulation (AC) medications. SSH is rare and, therefore, a systematic review is warranted to re-examine and outline trends, clinical characteristics, and outcomes associated with SSH formation. METHODS: PubMed, EMBASE, Scopus, and Web-of-Science were searched. Studies reporting clinical data of patients with SSH using AC medications were included. In addition, clinical studies meeting our a priori inclusion criteria limited to SSH were further defined in quality through risk bias assessment. RESULTS: We included 10 studies with 259 patients' pooled data post-screening 3083 abstracts. Within the cohort (n = 259), the prevalence of idiopathic, nontraumatic SSH with concomitant treatment with AC medications was greater 191 (73.75%) compared with AP treatment (27%). The lumbar spine was the most common site of hematoma (41.70%), followed by the cervical (22.01%) and thoracic (8.49%) spine. Most patients had surgical intervention (70.27%), and 29.73% had conservative management. The pooled data suggest that immediate diagnosis and intervention are the best prognostic factors in clinical outcomes. American Spinal Injury Association grading at initial symptom onset and post-treatment showed the greatest efficacy in symptomatic relief (87.64%) and return of motor and sensory symptoms (39.19%). CONCLUSIONS: Our review suggested that AC medications were related to SSH in most patients (74%), followed by APs (27%) and combined ACs + APs (1.9%). We recommend prompt intervention, a high suspicion for patients with neurologic deficits and diagnostic imaging before intervention to determine a case-specific treatment plan.

RESUMEN

BACKGROUND: Spontaneous spinal epidural hematoma is an infrequent yet potentially debilitating condition characterized by blood accumulation in the epidural space, with only 300 documented cases globally. Although the exact etiology of spontaneous spinal epidural hematoma remains poorly understood, theories suggest arteriovenous malformations, rupture of epidural vessels, or epidural veins as possible causes. CASE PRESENTATION: This study presents a 58-year-old Malay woman patient from Singapore with well-controlled hypertension, hyperlipidemia, type II diabetes mellitus, and microscopic hematuria. Despite a prior cystoscopy revealing no abnormalities, she presented to the emergency department with sudden-onset back pain, weakness, and numbness in both lower limbs. Rapidly progressing symptoms prompted imaging, leading to the diagnosis of a spinal epidural hematoma from thoracic (T) 9 to lumbar (L) 1. Prompt decompressive surgery was performed, and the patient is currently undergoing postoperative rehabilitation for paralysis. CONCLUSION: This case emphasizes the severity and life-altering consequences of spontaneous spinal epidural hematomas. Despite various proposed causative factors, a definitive consensus remains elusive in current literature. Consequently, maintaining a low threshold of suspicion for patients with similar presentations is crucial. The findings underscore the urgent need for swift evaluation and surgical intervention in cases of acute paraplegia.

RESUMEN

BACKGROUND: Cervical epidural hematoma (CEH) is defined as a collection of blood in the suprameningeal space. Mechanisms of this rare pathology include spontaneous, postsurgical, and traumatic as the main subtypes. This unique case of traumatic CEH represents an even smaller subset of these cases. Management varies by symptom presentation, mechanism of injury, and other contraindications. CASE PRESENTATION: This case presents a 32 year old African American female on an oral anticoagulant sustaining traumatic cervical hematoma after a motor vehicle collision. Patient complained of neck, abdominal, and back pain. Imaging revealed a cervical spinal hematoma at the level of C3-C6. This case discusses the management of CEH for the general population and in the setting of anticoagulation. CONCLUSION: Management of each case of CEH must be carefully considered and tailored based on their symptom presentation and progression of disease. As the use of anticoagulation including factor Xa inhibitors becomes more prevalent, there is greater need to understand the detailed pathophysiological aspect of the injuries. Targeted reversal agents such as Prothrombin Concentrate can be used for conservative treatment. Adjunct testing such as thromboelastogram can be used to help guide management.

RESUMEN

CASE: A 3-year-old boy presented to the emergency department with torticollis after a fall. With normal cervical radiographs and neurologic exam, he was diagnosed with cervical strain and discharged. After 2-week progressive symptoms, he was referred to a pediatric spine surgeon. Magnetic resonance imaging (MRI) revealed a cervical epidural hematoma, which was then surgically evacuated. He recovered fully and remains symptom-free 2 years later. CONCLUSION: Pediatric spinal epidural hematoma is a rare condition with potentially serious outcomes yet often nonspecific symptoms. Timely management based on a comprehensive evaluation of symptoms and imaging findings is crucial in improving patient outcomes.

RESUMEN

CASE: A 62-year-old woman who had an unremarkable medical history presented with sudden headache and neck pain. After the presentation, complete quadriplegia and respiratory arrest developed, and the patient was urgently intubated. Magnetic resonance imaging revealed an extensive epidural hematoma (EH), and emergency hematoma evacuation was performed. At the 1-year follow-up visit, the patient had no motor deficits. CONCLUSION: We reported a case of spontaneous cervical EH presenting with respiratory failure that was successfully treated with surgical management. Literature review has shown that the surgical outcome is very poor; nevertheless, prompt surgical decompression of the spinal cord can minimize neurological sequelae.
