Corticosteroid Therapy in Acute and Subacute Arachnoiditis - A Case Series.

Arachnoiditis is difficult to treat. Patients are often left frustrated after many failed trials of conservative therapies without symptom resolution. Surgery may provide symptom relief for a short period of time, but their pain often returned. Herein, we present three cases of acute arachnoiditis following three different pain procedures: epidural blood patch, IDDS implant, and epidural steroid injection. The patients were diagnosed and treated with corticosteroids within 10 days of the procedure. Two patients were treated with the same oral steroid regiment, while the third patient was treated with both oral and IV steroid. All three patients had good outcomes at the completion of their steroid therapy. This case series may provide insight into treating acute and subacute arachnoiditis from pain interventions.

Presumed post-traumatic subdural hygroma in a 2.5-year-old spayed female Chihuahua.

A 2.5-year-old spayed female Chihuahua dog was presented with chronic cervical pain and exhibited a "prayer-like position" following a history of a 4-meter fall. CT and MRI revealed a moderate right-sided enlargement of the subdural space with cerebrospinal fluid, consistent with a subdural hygroma, appearing connected to a quadrigeminal cistern dilation. Percutaneous transfontanellar external drainage of the subdural fluid accumulation did not prevent its re-accumulation, and the dog was managed medically, leading to the complete resolution of clinical signs. The subdural hygroma was suspected to be secondary to the previous trauma.

Anesthesia experience in an adult Silver-Russell syndrome: a case report.

BACKGROUND: There are no reports of anesthesia use in adult patients with Silver-Russell syndrome (SRS). Here, we report our experience with anesthesia in an adult patient with SRS complicated by chronic respiratory failure. CASE PRESENTATION: A 33-year-old woman was clinically diagnosed with SRS. She had severe chronic respiratory failure, complicated by superior mesenteric artery syndrome. Percutaneous gastrostomy was scheduled for nutritional management under epidural anesthesia; however, soon after esophagogastroduodenoscopy was started, she lost consciousness and spontaneous respiration. The patient was urgently intubated and converted to general anesthesia. The end-tidal carbon dioxide tension was > 90 mmHg at intubation. CONCLUSIONS: Adult SRS patients with chronic respiratory failure have a risk of CO2 narcosis. SRS also requires preparation for difficult airway management during the perioperative period.

Comparing Functional Efficacy of Transforaminal vs Interlaminar Epidural Steroid Injection for Lumbar Disc Disease!! Do We Really Need Transforaminal Epidural Route Injections?

This study compared the functional efficacy of therapeutic transforaminal versus interlaminar epidural steroid injection. Adult patients were selected and randomized using an online research randomizer website and assigned into two groups and were given epidural injection either via transforaminal route or interlaminar route. The outcome was measured based on the Modified Japanese Orthopedic Association back index score (mJOA), Oswestry disability index (ODI), and visual analog scale (VAS) over a follow-up on 1st, 3rd, and 6th month postinjection period. It was found that there was no significant difference seen in m JOA, ODI, and VAS score at 1 month, 3 months, and 6 months between transforaminal and interlaminar epidural steroid injection. Pain management in the epidural route was comparable to the interlaminar route. Even though the transforaminal epidural route has the advantage of being a selective nerve route block, it has similar results as the interlaminar route at 6 months follow-up.

A Case Report of Caudal Migration of a Lumbar Epidural Catheter Confirmed by Doppler Ultrasound: Ultrasound to the Rescue!

Combined spinal-epidural anaesthesia is an excellent technique for providing intraoperative and postoperative analgesia in patients undergoing total knee arthroplasty. Epidural catheters threaded through a Tuohy needle with a cephalad needle bevel orientation follow a winding pattern within the epidural space. Caudal or downward migration of an epidural catheter may lead to unsatisfactory anaesthesia and epidural failure. Colour flow Doppler sonography is emerging as an effective technique to determine the epidural catheter tip position. We report an interesting case of caudal migration of a lumbar epidural catheter confirmed by colour flow Doppler ultrasound.

Optimum programmed intermittent epidural bolus interval time of ropivacaine 0.0625% with dexmedetomidine 0.4 µg/ml at a fixed volume of 10 mL: a randomized controlled trial.

Background: The aim of our study was to administer adequate local anesthetic in programmed intermittent epidural bolus (PIEB) to avoid breakthrough pain and decrease the use of manual and PCEA boluses. We, therefore, conducted this study to determine the effective PIEB interval time between boluses of ropivacaine 0.0625% with dexmedetomidine 0.4 µg/ml at a fixed volume of 10 mL in 90% of subjects (EI90), without the use of patient-controlled epidural analgesia (PCEA). Methods: A total of 80 subjects were included in the final statistical analysis from 23 August 2022 to 22 November 2022. The subjects were randomly assigned to one of four different PIEB time intervals: 40, 50, 60, and 70 min (groups 40, 50, 60, and 70), respectively. The primary outcome was the effective epidural labor analgesia, defined as no use of PCEA bolus or a manual bolus until the end of the first stage of labor or within 6 hours after loading dose administration. The PIEB EI90 (95% CI) between boluses of ropivacaine 0.0625% with dexmedetomidine 0.4 µg/ml at a fixed volume of 10 mL was estimated using probit regression. Results: The effective PIEB interval time between boluses of ropivacaine 0.0625% with dexmedetomidine 0.4 µg/ml at a fixed volume of 10 mL in 90% of subjects without the use of PCEA was 45.4 (35.5-50.5) minutes using probit regression. No statistical differences were found in the proportion of subjects with Bromage score > 0, hypotension, pruritus, nausea, and vomiting between groups. However, the highest sensory block (pinprick) in the 40-min group was significantly higher than that in the other groups. Conclusion: The estimated value for EI90 for PIEB between boluses of ropivacaine 0.0625% with dexmedetomidine 0.4 µg/ml at a fixed volume of 10 mL using probit regression was 45.4 (35.5-50.5) minutes. Furthermore, future studies are warranted to be established to determine the optimal parameters for different regimens in clinical practice.

Acute Paraplegia Caused by Spinal Epidural Empyema Following Infectious Cellulitis of the Hand: Case Report and Literature Review.

Background Spinal epidural abscess is a rare but serious condition that can cause spinal cord compression and neurological deficits. Case Description and Methods The article reports a case of a 31-year-old patient who presented with an infectious cellulitis in the left hand, which progressed to a spinal epidural abscess. The diagnosis was confirmed by clinical examination and magnetic resonance imaging. Treatment involved laminectomy, after which the patient had complete recovery of neurological deficits. This article is a case report with a literature review. Patient data and images were collected by the researchers who participated in the patient's care. The literature was reviewed by one of the researchers based on the search for articles in the PubMed database. For the research, the following keywords were inserted: "Spinal epidural empyema," "Spinal epidural abscess." Conclusion Spinal epidural abscess is often underdiagnosed, which can lead to delays in treatment and serious complications. The relationship between cellulitis and spinal epidural abscess may be related to the spread of infection through the lymphatic or blood system.

Evaluation of neuraxial analgesia on outcomes for patients undergoing robot assisted abdominal surgery.

STUDY OBJECTIVE: Following robot assisted abdominal surgery, the pain can be moderate in severity. Neuraxial analgesia may decrease the activity of the detrusor muscle, reduce the incidence of bladder spasm and provide effective somatic and visceral analgesia. In this systematic review, we assessed the role of neuraxial analgesia in robot assisted abdominal surgery. DESIGN: Systematic review. SETTINGS: Robot assisted abdominal surgery. PATIENTS: Adults. INTERVENTIONS: Subsequent to a search of the electronic databases, observational studies and randomized controlled trials that assessed the effect of neuraxial analgesia instituted at induction of anesthesia or intraoperatively in adult and robot assisted abdominal surgery were considered for inclusion. The outcomes of observational studies as well as randomized controlled trials which were not subjected to meta-analysis were presented in descriptive terms. Meta-analysis was conducted if an outcome of interest was reported by two or more randomized controlled trials. MAIN RESULTS: We included 19 and 11 studies that investigated spinal and epidural analgesia in adults, respectively. The coprimary outcomes were the pain score at rest at 24 h and the cumulative intravenous morphine consumption at 24 h. Spinal analgesia with long acting neuraxial opioid did not decrease the pain score at rest at 24 h although it reduced the cumulative intravenous morphine consumption at 24 h by a mean difference (95%CI) of 14.88 mg (-22.13--7.63; p < 0.0001, I2 = 50%) with a low and moderate quality of evidence, respectively, on meta-analysis of randomized controlled trials. Spinal analgesia with long acting neuraxial opioid had a beneficial effect on analgesic indices till the second postoperative day and a positive influence on opioid consumption up to and including the 72 h time point. The majority of studies demonstrated the use of spinal analgesia with long acting neuraxial opioid to lead to no difference in the incidence of postoperative nausea and vomiting, and the occurrence of pruritus was found to be increased with spinal analgesia with long acting neuraxial opioid in recovery but not at later time points. No difference was revealed in the incidence of urinary retention. The evidence in regard to the quality of recovery-15 score at 24 h and hospital length of stay was not fully consistent, although most studies indicated no difference between spinal analgesia and control for these outcomes. Epidural analgesia in robot assisted abdominal surgery was shown to decrease the pain on movement at 12 h but it had not been studied with respect to its influence on the pain score at rest at 24 h or the cumulative intravenous morphine consumption at 24 h. It did not reduce the pain on movement at later time points and the evidence related to the hospital length of stay was inconsistent. CONCLUSIONS: Spinal analgesia with long acting neuraxial opioid had a favourable effect on analgesic indices and opioid consumption, and is recommended by the authors, but the evidence for spinal analgesia with short acting neuraxial opioid and epidural analgesia was limited.

Reirradiation of metastases of the central nervous system: part 2-metastatic epidural spinal cord compression.

An increasing number of patients irradiated for metastatic epidural spinal cord compression (MESCC) experience an in-field recurrence and require a second course of radiotherapy. Reirradiation can be performed with conventional radiotherapy or highly-conformal techniques such as intensity-modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT), and stereotactic body radiation therapy (SBRT). When using conventional radiotherapy, a cumulative biologically effective dose (BED) ≤120 calculated with an α/ß value of 2 Gy (Gy2) was not associated with radiation myelopathy in a retrospective study of 124 patients and is considered safe. In that study, conventional reirradiation led to improvements of motor deficits in 36% of patients and stopped further symptomatic progression in another 50% (overall response 86%). In four other studies, overall response rates were 82-89%. In addition to the cumulative BED or equivalent dose in 2 Gy fractions (EQD2), the interval between both radiotherapy courses <6 months and a BED per course ≥102 Gy2 (corresponding to an EQD2 ≥51 Gy2) were identified as risk factors for radiation myelopathy. Without these risk factors, a BED >120 Gy2 may be possible. Scoring tools have been developed that can assist physicians in estimating the risk of radiation myelopathy and selecting the appropriate dose-fractionation regimen of re-treatment. Reirradiation of MESCC may also be performed with highly-conformal radiotherapy. With IMRT or VMAT, rates of pain relief and improvement of neurologic symptoms of 60-93.5% and 42-73%, respectively, were achieved. One-year local control rates ranged between 55% and 88%. Rates of myelopathy or radiculopathy and vertebral compression fractures were 0% and 0-9.3%, respectively. With SBRT, rates of pain relief were 65-86%. Two studies reported improvements in neurologic symptoms of 0% and 82%, respectively. One-year local control rates were 74-83%. Rates of myelopathy or radiculopathy and vertebral compression fractures were 0-4.5% and 4.5-13.8%, respectively. For SBRT, a cumulative maximum EQD2 to thecal sac ≤70 Gy2, a maximum EQD2 of SBRT ≤25 Gy2, a ratio ≤0.5 of thecal sac maximum EQD2 of SBRT to maximum cumulative EQD2, and an interval between both courses ≥5 months were associated with a lower risk of myelopathy. Additional prospective trials are required to better define the options of reirradiation of MESCC.

[Middle meningeal artery embolization to treat acute epidural haematoma, case report and literature review]. / Akut epiduralis haematoma kezelése arteria meningea media embolisatióval, esetismertetés és irodalmi áttekintés.

The treatment of acute epidural haematoma is surgery as soon as possible, elimination of the source of bleeding and evacuation of the haematoma. In case of small epidural haematoma, strict neurological and radiological follow-up is necessary. In a significant percentage of cases, open surgery must also be performed within a few days. In case of small epidural haematomas, embolization of the middle meningeal artery is considered as an alternative solution. We review the literature on middle meningeal artery embolization and present our first treatment. Our case report is the first European report about an acute epidural haematoma which was treated by embolization of middle meningeal artery. Our case study is the first report in which a patient was treated with both open surgery and endovascular treatment for acute epidural haematoma within a year.

Using part of the initial analgesic dose as the epidural test dose did not delay the onset of labor analgesia: a randomized controlled clinical trial.

BACKGROUND: Epidural test dose for labor analgesia is controversial and varies widely in clinical practice. It is currently unclear whether using a portion of the initial dose for analgesia as the test dose delays the onset time of analgesia, compared to the traditional test dose. METHODS: One hundred and twenty-six parturients who chose epidural analgesia during labor were randomly assigned to two groups. The first dose in group L was 3 ml 1.5% lidocaine, and in the RF group was 10 ml 0.1% ropivacaine combined with 2 µg/ml fentanyl. After 3 min of observation, both groups received 8 ml 0.1% ropivacaine combined with 2 µg/ml fentanyl. The onset time of analgesia, motor and sensory blockade level, numerical pain rating scale, patient satisfaction score, and side effects were recorded. RESULTS: The onset time of analgesia in group RF was similar to that in group L (group RF vs group L, 7.0 [5.0-9.0] minutes vs 8.0 [5.0-11.0] minutes, p = 0.197). The incidence of foot numbness (group RF vs group L, 34.9% vs 57.1%, p = 0.020) and foot warming (group RF vs group L, 15.9% vs 47.6%, p < 0.001) in group RF was significantly lower than that in group L. There was no difference between the two groups on other outcomes. CONCLUSIONS: Compared with 1.5% lidocaine 3 ml, 0.1% ropivacaine 10 ml combined with 2 µg/ml fentanyl as an epidural test dose did not delay the onset of labor analgesia, and the side effects were slightly reduced.

Noninferiority trials in acute pain research: a valid approach or a slippery slope?

The conduct and reporting of studies with a noninferiority hypothesis is challenging because of the complexity involved in their design and interpretation. However, studies with a noninferiority design have increased in popularity. A recently published trial reported on the noninferiority of lidocaine infusion to epidural analgesia in major abdominal surgeries. Apart from needing a critical appraisal, this draws attention to improve our understanding of noninferiority study framework and its unique features. Given the increasing focus on using various analgesic adjuncts and multiple approaches to fascial plane blocks to avoid more definitive and standard approaches, it is imperative that particular attention is paid to appropriate execution and reporting of noninferiority studies.

Cost-effectiveness of Transforaminal epidural steroid injections for patients with ACUTE sciatica: a randomized controlled trial.

BACKGROUND: Transforaminal epidural injections with steroids (TESI) are increasingly being used in patients sciatica. The STAR (steroids against radiculopathy)-trial aimed to evaluate the (cost-) effectiveness of TESI in patients with acute sciatica (< 8 weeks). This article contains the economic evaluation of the STAR-trial. METHODS: Participants were randomized to one of three study arms: Usual Care (UC), that is oral pain medication with or without physiotherapy, n = 45); intervention group 1: UC and transforaminal epidural steroid injection (TESI) 1 ml of 0.5% Levobupivacaine and 1 ml of 40 mg/ml Methylprednisolone and intervention group 2: UC and transforaminal epidural injection (TEI) with 1 ml of 0,5% Levobupivacaine and 1 ml of 0.9% NaCl (n = 50). The primary effect measure was health-related quality of life. Secondary outcomes were pain, functioning, and recovery. Costs were measured from a societal perspective, meaning that all costs were included, irrespective of who paid or benefited. Missing data were imputed using multiple imputation, and bootstrapping was used to estimate statistical uncertainty. RESULTS: None of the between-group differences in effects were statistically significant for any of the outcomes (QALY, back pain, leg pain, functioning, and global perceived effect) at the 26-weeks follow-up. The adjusted mean difference in total societal costs was €1718 (95% confidence interval [CI]: - 3020 to 6052) for comparison 1 (intervention group 1 versus usual care), €1640 (95%CI: - 3354 to 6106) for comparison 2 (intervention group 1 versus intervention group 2), and €770 (95%CI: - 3758 to 5702) for comparison 3 (intervention group 2 versus usual care). Except for the intervention costs, none of the aggregate and disaggregate cost differences were statistically significant. The maximum probability of all interventions being cost-effective compared to the control was low (< 0.7) for all effect measures. CONCLUSION: These results suggest that adding TESI (or TEI) to usual care is not cost-effective compared to usual care in patients with acute sciatica (< 8 weeks) from a societal perspective in a Dutch healthcare setting. TRIAL REGISTRATION: Dutch National trial register: NTR4457 (March, 6th, 2014).

Revolutionizing Back Pain Management: Is Epidural Platelet-Rich Plasma the Superior Choice Over Steroids?

Background and objective Low back discomfort is one of the main factors that restrict physical activity, and it is becoming more and more common. Surgery is the best option when all other conservative treatment methods have failed, but it is not a panacea. While local anesthetic-free and combined epidural steroid injections have been used for many years, their usefulness is limited to shorter periods. In the field of orthopedics, platelet-rich plasma (PRP) has gained widespread recognition as an adjuvant component. PRP has been applied to improve tissue repair, both soft and hard. This comparative study aimed to evaluate the potential of PRP as a therapy for low back pain (LBP). Methods We included 64 adult individuals with complaints of LBP. They were classified into two groups: group A underwent a single injection in the afflicted lumbar intervertebral disc (IVD) level with 1.5 ml of methylprednisolone, 1.5 ml 2% lidocaine, and 0.5 ml of saline under rigorous aseptic precautions; in contrast, group B was administered a single injection of 3 milliliters of autologous PRP. Patients' scores on the visual analog scale (VAS), the Modified Oswestry Disability Questionnaire (MODQ), and the Straight Leg Raising Test (SLRT) were assessed before and during therapy. Results The data gathered were subjected to statistical analysis. Statistically significant differences were found in the VAS scores between group A (methylprednisolone group) and group B (PRP group) post-one hour (6.0 ±0.74 vs. 6.92 ±0.57) and after three months (5.2 ±0.65 vs. 3.26 ±0.79). Conclusions Our study revealed gradual progressive improvement in the symptoms of patients in the PRP group as indicated by scores on SLRT, VAS, and MODQ. The results were comparable to those who received methylprednisolone injections. There was a statistically significant difference in VAS scores between the two groups, with the PRP group reporting a higher degree of pain reduction, showing that PRP is an effective alternative to epidural steroid infiltration in managing chronic LBP.

Effect of blind versus fluoroscopic guidance epidural blood patch in patients with intracranial hypotension.

Epidural blood patch (EBP)-the most effective treatment for intracranial hypotension (IH)-can be performed using the blind technique in the lateral position or under fluoroscopic guidance in the prone position. This study aimed to compare the effectiveness of EBP in patients with spontaneous intracranial hypotension (sIH) and iatrogenic intracranial hypotension (iIH) when performed with the blind technique in the lateral decubitus position or fluoroscopic guidance in the prone position. We reviewed IH patients who underwent EBP between January 2015 and September 2019 in a single hospital and divided them into two groups according to the type of IH. Of the 84 included patients, 36 had sIH and 48 had iIH. We compared the effectiveness of EBP using the two methods in each group. There was no significant difference in the effect of EBP between the patients with iIH (p > 0.05). For patients with sIH, fluoroscopic guidance in the prone position technique showed better improvement than the blind technique in the lateral decubitus position (p < 0.05). We observed similar outcomes after blind EBP versus fluoroscopic guidance EBP in patients with iIH. However, procedure-dependent differences were observed in patients with sIH. For patients with sIH, it would be effective to consider fluoroscopic EBP first. Further study is needed to investigate interactions between method of EBP and other factors that affect the effectiveness of EBP.

Clinical presentation and treatment of 26 spinal epidural arteriovenous fistulas: a single-center experience.

BACKGROUND: Spinal epidural arteriovenous fistulas (SEDAVFs) are rarely diagnosed vascular malformations that can cause spinal cord compression and congestive myelopathy. METHODS: This is a single-center, retrospective case series of patients with SEDAVFs who underwent observation or treatment at UCLA medical center between 1993 and 2023. RESULTS: Between 1993 and 2023 a total of 26 patients at UCLA were found to have a SEDAVF. The median age at treatment was 59 years (range 4 months to 91 years). Compared with sacral, lumbar, and thoracic SEDAVFs, patients with cervical SEDAVF were younger (41 years vs 63 years, P=0.016) and more likely to be female (66.7% vs 14.3%, P=0.006). Possible triggers for development of SEDAVFs may be prior spinal surgery or trauma (n=4), turning the neck (n=1), lifting a heavy box (n=1), a prolonged period of bending over (n=1), and neurofibromatosis type 1 (n=1). Of the 22 patients treated endovascularly, 18 (82%) were angiographically cured on the first attempt without complications. One patient underwent surgical treatment alone and had a failed surgery on the first attempt, and developed a surgical site infection after the second successful attempt at treatment. Of the 16 patients with adequate clinical follow-up, 11 (69%) demonstrated early improved clinical outcome (eg, improved strength on examination, absent bruit). CONCLUSIONS: SEDAVFs are a rarely diagnosed disease that can be treated effectively and safely with endovascular embolization in most cases. Patients with sacral, lumbar, and thoracic SEDAVFs were older and more often male compared to patients with cervical SEDAVFs.

Case report: Simultaneous measurement of intracranial pressure and lumbar intrathecal pressure during epidural patch therapy for treating spontaneous intracranial hypotension syndrome. Spontaneous intracranial hypotension or spontaneous intraspinal hypovolume?

Objectives: Spontaneous intracranial hypotension (SIH) is frequently complicated by subacute subdural hematoma (SDH) and more rarely by bilateral thalamic ischemia. Here, we report a case of SIH-related SDH treated with three epidural patches (EPs), with follow-up of the intracranial pressure and lumbar intrathecal pressure. Methods: A 46-year-old man presented bilateral thalamic ischemia, then a growing SDH. After failure of urgent surgical evacuation, he underwent three saline EPs, two dynamic myelography examinations and one digital subtraction angiography-phlebography examination. However, because of no dural tear and no obstacle to the venous drainage of the vein of Galen, no therapeutic procedure was available, and the patient died. Results: The case exhibited a progressive increase in the transmission of lumbar intrathecal pressure to intracranial pressure during the three EPs. The EPs may have successfully treated the SIH, but the patient did not recover consciousness because of irreversible damage to both thalami. Conclusion: Clinicians should be aware of the bilateral thalamic ischemia picture that may be the presenting sign of SIH. Moreover, the key problem in the pathophysiology of SIH seems to be intraspinal and intracranial volumes rather than pressures. Therefore, intracranial hypotension syndrome might actually be an intraspinal hypovolume syndrome.

Safety and effectiveness of butorphanol in epidural labor analgesia: A protocol for a systematic review and meta-analysis.

BACKGROUND: Epidural analgesia is the most effective analgesic method during labor. Butorphanol administered epidurally has been shown to be a successful analgesic method during labor. However, no comprehensive study has examined the safety and efficacy of using butorphanol as an epidural analgesic during labor. AIM: To assess butorphanol's safety and efficacy for epidural labor analgesia. METHODS: The PubMed, Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure, and Google Scholar databases will be searched from inception. Other types of literature, such as conference abstracts and references to pertinent reviews, will also be reviewed. We will include randomized controlled trials comparing butorphanol with other opioids combined with local anesthetics for epidural analgesia during labor. There will be no language restrictions. The primary outcomes will include the visual analog scale score for the first stage of labor, fetal effects, and Apgar score. Two independent reviewers will evaluate the full texts, extract data, and assess the risk of bias. Publication bias will be evaluated using Egger's or Begg's tests as well as visual analysis of a funnel plot, and heterogeneity will be evaluated using the Cochran Q test, P values, and I2 values. Meta-analysis, subgroup analysis, and sensitivity analysis will be performed using RevMan software version 5.4. This protocol was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Protocols statement, and the PRISMA statement will be used for the systematic review. RESULTS: This study provides reliable information regarding the safety and efficacy of using butorphanol as an epidural analgesic during labor. CONCLUSION: To support clinical practice and development, this study provides evidence-based findings regarding the safety and efficacy of using butorphanol as an epidural analgesic during labor.

Medical malpractice and epidural hematomas: a retrospective analysis of 101 cases in the United States.

Background: Neurosurgeons face particularly high rates of litigation compared to physicians in other fields. Malpractice claims are commonly seen after mismanagement of life-threatening medical emergencies, such as epidural haematomas. Due to the lack of legal analysis pertaining to this condition, the aim of this study is to identify risk factors associated with litigation in cases relating to the diagnosis and treatment of epidural haematomas. Materials and methods: Westlaw Edge, an online database, was used to analyze malpractice cases related to epidural haematomas between 1986 and 2022. Information regarding plaintiff demographics, defendant specialty, reason for litigation, trial outcomes, and payouts for verdicts and settlements were recorded. Comparative analysis between cases that returned a jury verdict in favour of the plaintiff versus defendant was completed. Results: A total of 101 cases were included in the analysis. Failure to diagnose was the most common reason for litigation (n = 64, 63.4%), followed by negligent care resulting in an epidural haematoma (n = 44, 43.6%). Spine surgery (n = 29, 28.7%), trauma (n = 28, 27.7%), and epidural injection/catheter/electrode placement (n = 21, 20.8%) were the primary causes of haematomas. Neurosurgeons (n = 18, 17.8%) and anesthesiologists (n = 17, 16.8%) were the two most common physician specialties cited as defendants. Most cases resulted in a jury verdict in favour of the defense (n = 54, 53.5%). For cases ending in plaintiff verdicts, the average payout was $3 621 590.45, while the average payment for settlements was $2 432 272.73. Conclusion: Failure to diagnose epidural haematomas is the most common reason for malpractice litigation, with neurosurgeons and anesthesiologists being the most common physician specialties to be named as defendants. More than half of all cases returned a jury verdict in favour of the defense and, on average, settlements proved to be more cost-effective than plaintiff verdicts.

Spontaneous Intracranial Hypotension: Clinical Presentation, Diagnosis, and Treatment Strategies.

Spontaneous intracranial hypotension (SIH) typically presents as an acute orthostatic headache during an upright position, secondary to spinal cerebrospinal fluid leaks. New evidence indicates that a lumbar puncture may not be essential for diagnosing every patient with SIH. Spinal neuroimaging protocols used for diagnosing and localizing spinal cerebrospinal fluid leaks include brain/spinal MRI, computed tomography myelography, digital subtraction myelography, and radionuclide cisternography. Complications of SIH include subdural hematoma, cerebral venous thrombosis, and superficial siderosis. Treatment options encompass conservative management, epidural blood patches, and surgical interventions. The early application of epidural blood patches in all patients with SIH is suggested.
