Acute spinal subdural hematoma with hemiplegia after acupuncture: a case report and review of the literature

Therapeutic Options for Migraines in the Microsurgical Patient: A Scoping Review

BACKGROUND

There exists an increasing array of treatments proposed to prevent, alleviate, and abort symptoms of a migraine; however, for patients who undergo reconstructive microsurgery, caution must be taken to preserve vascular integrity. This study is the first-to-date scoping review of vascular and bleeding risk of current migraine therapies, with the purpose of identifying potential therapeutic agents for postoperative migraine management appropriate for microsurgical patients.

METHODS

Currently available migraine therapeutics were compiled from the UpToDate software system and the American Academy of Family Physicians. A PubMed literature review was performed for each therapeutic's effect on bleeding or vascular involvement. Data were compiled into tables of abortive, symptom-controlling and prophylactic, and nonpharmacologic treatments. Expert microsurgeons reviewed the data to provide recommendations for optimized patient care.

RESULTS

Triptans and other ergot derivatives demonstrated strong evidence of vasoconstriction and were greatly advised against for immediate postmicrosurgical use. Novel pharmaceutical therapies such as lasmiditan and calcitonin gene-related peptide antagonists have no literature indicating potential for vasoconstriction or hematoma and remain an investigational option for abortive medical treatment. For symptom control, acetaminophen appears the safest option, with clinical judgment and further research needed for use of nonsteroidal antiinflammatory drugs. Alternative treatment techniques may include migraine prophylaxis with botulinum toxin injection or nutraceutical treatment by means of magnesium supplementation or coenzyme Q10 administration, minimizing the need for additional medication in the postoperative setting.

CONCLUSIONS

Patients undergoing reconstructive microsurgery have a unique medical profile limiting the therapeutic options available to treat migraines. This review provides preliminary evidence to be considered as a guide for prescribing therapeutics for migraine in the postoperative setting.

Publication status and reporting quality of case reports on acupuncture-related adverse events: A systematic reviews of case studies

Introduction

Case reports on acupuncture-related adverse events (AEs) have been consistently published in the literature. This review aims to assess the current publication status of case reports on acupuncture-related AEs and evaluate their reporting quality in order to identify areas for improvement.

Methods

This study is a systematic review (SR) of case reports. Studies describing cases for acupuncture-related AEs between 2010 and 2023 (until July) were searched in PubMed, Embase, and local databases (China and Korea), as well as by hand-searching references included in published relevant SRs. A bibliometric analysis was conducted to examine the publication trends of the included literature. The appropriateness of the acupuncture described in the cases, the causality assessment between AEs and acupuncture treatment, and the presence of necessary items from the CAse REport guidelines (CARE) checklist were narratively analyzed.

Results

A total of 169 case reports were included in this review. Over the past decade, an average of 12 case reports on acupuncture-related AEs were published annually. However, only 38.2% of the articles provided sufficient information to determine the appropriateness of the acupuncture treatment used in the reported cases, and considerable numbers of the included case reports did not suggest enough information for the assessment of a causal relationship. The majority of cases did not report the timeline (n = 164), patient perspectives (n = 157), and informed consent (n = 121) items from the CARE checklist.

Discussion

Acupuncture-related AEs persist in being frequently reported in the literature. Nonetheless, the information concerning acupuncture and causality assessment within these publications is still found to be insufficient. The development of reporting guidelines for future case reports on acupuncture-related AEs is anticipated to promote an academic environment conducive to more comprehensive reporting.

Bleeding risk after acupuncture in patients taking anticoagulant drugs: a case control study based on real-world data

OBJECTIVES

Patients on anticoagulant medications may be at a higher risk of bleeding after acupuncture. This study aimed to assess the association between anticoagulant drug use and bleeding after acupuncture.

DESIGN

Case control study SETTING: We analysed the diagnosis and treatment records (2000-2018) of a random sample of two million patients from the National Health Insurance Research Database in Taiwan.

INTERVENTIONS

anticoagulant and antiplatelet drugs MAIN OUTCOME MEASURES: The incidence rates of major (visceral bleeding or ruptured blood vessels requiring transfusion) and minor (skin bleeding or contusion) bleeding after acupuncture RESULTS: We included the records of 13,447,563 acupuncture sessions in 821,946 participants and followed up the patients for 14 days after each session. The incidence of minor bleeding was 8.31 per 10,000 needles, whereas that of major bleeding was 4.26 per 100,000 needles. Anticoagulants significantly increased the risk of minor bleeding (adjusted OR = 1.15 (1.03-1.28)), but the risk of major bleeding did not reach statistical significance (adjusted OR = 1.18 (0.8 0-1.75)). Anticoagulants, such as warfarin (adjusted OR = 4.95 (2.55-7.64)), direct oral anticoagulants (adjusted OR = 3.07 (1.23-5.47)), and heparin (adjusted OR = 3.72 (2.18-6.34)) significantly increased the risk of bleeding. However, antiplatelet drug was not significantly associated with post-acupuncture bleeding. Comorbidities including liver cirrhosis, diabetes, and coagulation defects, were the risk factors for bleeding after acupuncture.

CONCLUSIONS

Anticoagulant drugs may increase the risk of bleeding after acupuncture. We encourage physicians to ask patients in detail about their medical history and drug use prior to acupuncture treatment.

Neck pain and absence of cranial nerve symptom are clues of cervical myelopathy mimicking stroke: Two case reports

BACKGROUND

Cervical myelopathy is a potential stroke imitator, for which intravenous thrombolysis would be catastrophic.

CASE SUMMARY

We herein present two cases of cervical myelopathy. The first patient presented with acute onset of right hemiparesis and urinary incontinence, and the second patient presented with sudden-onset right leg monoplegia. The initial diagnoses for both of them were ischemic stroke. However, both of them lacked cranial nerve symptom and suffered neck pain at the beginning of onset. Their cervical spinal cord lesions were finally confirmed by cervical computed tomography. A literature review showed that neck pain and absence of cranial nerve symptom are clues of cervical myelopathy.

CONCLUSION

The current report and the review remind us to pay more attention to these two clues in suspected stroke patients, especially those within the thrombolytic time window.

Risk Factor Analysis and Surgical Outcomes of Acute Spontaneous Spinal Subdural Hematoma. An Institutional Experience of Four Cases and Literature Review

OBJECTIVE

Spontaneous spinal subdural hematoma (SSSDH) is exceedingly rare, with significant morbidity in most patients. Acute neurologic deficit in the context of a SSSDH is considered a neurosurgical emergency. We performed a literature review and compared the results with our institutional experience to evaluate the risk factors and neurologic outcomes of SSSDH.

METHODS

We retrospectively collected the medical, radiologic, and surgical information of 4 patients with SSSDH who were operated on in our neurosurgical unit. A literature review of surgically managed patients with SSSDH and their neurologic outcomes was performed. Ordered logistic regression statistics were used to study the risk factors influencing the postoperative Domenicucci grade.

RESULTS

A total of 112 patients were evaluated, with a female/male ratio of 1.3:1. Mean patient age was 60.25 years. Our analysis of the data showed that the cohort of patients presenting with bladder dysfunction in addition to paraparesis were found to have worse neurologic outcomes postoperatively. Adjusted analysis identified 3 clinical characteristics that influenced surgical outcome: cervical SSSDH (P = 0.029), neurologic deficit (P < 0.001), and anticoagulation medication (P < 0.001).

CONCLUSIONS

This review shows that patients aged ≥60 years and on anticoagulation are at an increased risk of sustaining a spontaneous subdural spinal hematoma without history of trauma. To our knowledge, this is also the first study to show a presenting symptom of bladder dysfunction as a significant risk factor for poor surgical outcome in SSSDH. Our study supports surgical evacuation of acute SSSDH in the presence of these risk factors.

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.

Iatrogenic Spinal Subdural Hematoma due to Apixaban: A Case Report and Review of the Literature

In the last decade, the clinical relevance for developing safer oral anticoagulants prompted the development of new classes of drugs that have shown a lower risk of life-threatening bleeding events as compared to standard warfarin. Nontraumatic spinal subdural hematoma is an uncommon urgent complication that can be associated with the use of these agents. An unusual case of spinal subdural hematoma related to apixaban treatment for nonrheumatic atrial fibrillation is reported here.

The rising root sign: the magnetic resonance appearances of post-operative spinal subdural extra-arachnoid collections

We present a case series of symptomatic post-operative spinal subdural extra-arachnoid collections that displace the cauda equina roots anteriorly. This is described as the "rising root sign".

A Multicenter Prospective Survey of Adverse Events Associated with Acupuncture and Moxibustion in Japan

Background: There have been only a few prospective surveys on adverse events (AEs) in Japanese-style acupuncture practice, and these surveys were conducted only in a single college acupuncture clinic. Objective: The goal of this research was to assess the safety of acupuncture and moxibustion performed in educational facilities in Japan. Materials and Methods: This was a multicenter prospective survey, using paper reporting forms. It was conducted in eight acupuncture clinics affiliated with educational institutions. The subjects were outpatients attending the clinics. The main outcome measure was the number of reported adverse events. The study was conducted for 5-7 months at each facility between October 2014 and June 2015. Participating acupuncture practitioners were instructed to self-report AEs observed during and after treatment; patients were interviewed upon treatment completion. For returning patients, treatment was preceded by an interview survey regarding the AEs identified after the previous treatment session. A specialized 4-sheet questionnaire was used. Results: Two hundred and thirty-two acupuncture practitioners participated, 2180 patients received treatment, and there were 14,039 sessions, overall. In total, 847 (6.03%) AEs were reported. The most common AEs included subcutaneous bleeding and hematomas (370, 2.64%), followed by discomfort (109, 0.78%) and residual pain at insertion points (94, 0.67%). No infections or serious AEs were reported. Conclusions: Acupuncture and moxibustion performed in educational facilities in Japan were safe because most of the AEs reported were mild and transient. However, the risk cannot be defined definitely because the survey sample size was too small.

An Acute Cervical Subdural Hematoma as the Complication of Acupuncture: Case Report and Literature Review

BACKGROUND

Several injuries in the cervical region as complications of acupuncture have been previously reported in the literature, including cord and medulla oblongata injuries, subdural empyema, and cervical hematoma. Spinal cord subdural hematoma is a rare condition mainly associated with coagulopathy, trauma, and iatrogenic procedures. We herein report an acute cervical subdural hematoma after cervical acupuncture for neck and shoulder pain.

CASE DESCRIPTION

A 74-year-old woman presented with progressive quadriparesis and sensory deficit after receiving acupuncture in the neck and shoulder. Magnetic resonance imaging of the cervical spine showed a subdural lesion that was a hyperintense mass in the T1-weighted and hypointense in T2-weighted images at the C4-C6 level, which proved to be an early subacute subdural hematoma. After surgical evacuation of the hematoma, the patient had significant neurologic improvement.

CONCLUSIONS

Although rare, cervical spinal cord hematomas are disastrous complications of cervical acupuncture. These procedures should be performed under direct observation of trained physicians with appropriate knowledge of cervical anatomy to avoid these complications.

Thoracic spinal subdural hematoma complicating anterior cervical discectomy and fusion: case report

A spinal subdural hematoma is a rare clinical entity with considerable consequences without prompt diagnosis and treatment. Throughout the literature, there are limited accounts of spinal subdural hematoma formation following spinal surgery. This report is the first to describe the formation of a spinal subdural hematoma in the thoracic spine following surgery at the cervical level. A 53-year-old woman developed significant paraparesis several hours after anterior cervical discectomy and fusion of C5–6. Expeditious return to operating room for anterior cervical revision decompression was performed, and the epidural hematoma was evacuated without difficulty. Postoperative imaging demonstrated a subdural hematoma confined to the thoracic level, and the patient was returned to the operating room for a third surgical procedure. Decompression of T1–3, with evacuation of the subdural hematoma was performed. Postprocedure, the patient’s sensory and motor deficits were restored, and, with rehabilitation, the patient gained functional mobility. Spinal subdural hematomas should be considered as a rare but potential complication of cervical discectomy and fusion. With early diagnosis and treatment, favorable outcomes may be achieved.

Three cases of hemiplegia after cervical paraspinal muscle needling

BACKGROUND CONTEXT

Muscle needling therapy is common for chronic pain management, but the development of unusual complications such as hemiplegia is not well understood.

PURPOSE

We report on three cases with hemiplegia after cervical paraspinal muscle needling and propose possible explanations for these unusual complications.

STUDY DESIGN

Case report.

METHODS

The authors retrospectively reviewed the medical charts from a decade (2002-2013) at Korea University Hospital. The records were systematically searched, and the cases with hemiplegia (grade<3) after needing therapy were collected. No conflict of interest reported. No funding received.

RESULTS

A 54-year-old woman, a 38-year-old woman, and a 60-year-old man with hemiplegia by cervical subdural or epidural hematoma after cervical posterior paraspinal muscle needling without direct invasion (intramuscular stimulation, acupuncture, or intramuscular lidocaine) were observed. All patients were taken for emergent decompressive laminectomy, and their postoperative motor function improved substantially.

CONCLUSION

Spinal hematoma after muscle needling is unusual but was thought to result after a rupture of the epidural or subarachnoid veins by a sharp increase in blood pressure delivered in the intraabdominal or intrathoracic areas after needling therapy.

Acute spontaneous spinal subdural hematoma with vague symptoms

Spinal subdural hematoma is a rarely reported disease and spontaneous spinal subdural hematomas (SSDH) without underlying pathological changes are even rarer. The patients usually show typical symtoms such as back pain, quadriplegia, paraplegia or sensory change. But rarely, patients may show atypical symptoms such as hemiparesis and misdiagnosed to cerebrovascular accident. We recently experienced a case of SSDH, where the patient initially showed vague symptoms, such as the sudden onset of headache which we initially misdiagnosed as subarachnoid hemorrhage. In this case, the headache of patient improved but the neck pain persisted until hospital day 5. Therefre, we conducted the MRI of cervical spine and finally confirmed SSDH. The patient was managed conservatively and improved without recurrence. In this case report, we discuss the clinical features of SSDH with emphasis on the importance of an early diagnosis.
