Subdural haematoma after dural puncture headache treated by epidural blood patch

Intracranial hematoma and abscess after neuraxial analgesia and anesthesia: a review of the literature describing 297 cases

BACKGROUND

Besides spinal complications, intracranial hematoma or abscess may occur after neuraxial block. Risk factors and outcome remain unclear.

OBJECTIVE

This review evaluates characteristics, treatment and recovery of patients with intracranial complications after neuraxial block.

EVIDENCE REVIEW

We systematically searched MEDLINE, Embase and the Cochrane Library from their inception to May 2020 for case reports/series, cohort studies and reviews of intracranial hematoma or abscess associated with neuraxial block. Quality of evidence was assessed using the critical appraisal of a case study checklist by Crombie.

FINDINGS

We analyzed 232 reports, including 291 patients with hematoma and six patients with abscess/empyema. The major part of included studies comprised single case reports with a high risk of bias. Of the patients with hematoma, 48% concerned obstetric patients, the remainder received neuraxial block for various perioperative indications or pain management. Prior dural puncture was reported in 81%, either intended (eg, spinal anesthesia) or unintended (eg, complicated epidural catheter placement). Headache was described in 217 patients; in 101 patients, symptoms resembled postdural puncture headache (PDPH). After treatment, 11% had partial or no recovery and 8% died, indicating the severity of this complication. Intracranial abscess after neuraxial block is seldom reported; six reports were found.

CONCLUSION

Diagnosis of intracranial hematoma is often missed initially, as headache is assumed to be caused by cerebrospinal hypotension due to cerebrospinal fluid leakage, known as PDPH. Prolonged headache without improvement, worsening symptoms despite treatment or epidural blood patch, change of headache from postural to non-postural or new neurological signs should alert physicians to alternative diagnoses.

Postpartum Bilateral Subdural Hematomas: A Case Report

Postpartum headache is a common emergency department (ED) complaint in women following delivery. Though the majority of these headaches are due to primary headache disorders or postdural puncture headaches, life-threatening complications can occur. Both postpartum pre-eclampsia can occur as well as hypercoagulable and vascular disorders including stroke, venous sinus thrombosis (VST), and reversible cerebral vasoconstrictive syndrome. With the increasing use of epidurals for intrapartum analgesia, rare, dangerous complications can present in a similar fashion. The authors present a persistent postpartum headache secondary to bilateral subdural hematomas (SDH) from epidural induced intracranial hypotension.

Repeat Subdural Hematoma After Uncomplicated Lumbar Drain Discontinuation: A Case Report

Lumbar drains are commonly placed to monitor spinal cerebrospinal fluid (CSF) pressures and drain CSF to augment spinal cord perfusion. Excessive CSF drainage or persistent leakage through the dural puncture site can lead to cerebral hypotension and creation of an intracranial subdural hematoma. Anesthesia providers need to be aware of the risk of subdural hematoma development after major thoracoabdominal surgery where placement and subsequent removal of a lumbar drain have occurred. We present a patient who had recurrent subdural hematoma secondary to persistent undiagnosed CSF leak from the dural puncture site after uncomplicated placement and removal of a lumbar drain.

Subdural hematoma after cesarean delivery without symptoms: a case report

Background

Subdural hematoma (SDH) after accidental dural puncture (ADP) is rare but may be lethal. We experienced a patient who developed SDH after combined spinal and epidural anesthesia without a headache.

Case presentation

A 41-year-old parturient female with an unruptured cerebral aneurysm, was scheduled to undergo elective cesarean delivery. Cerebrospinal fluid leakage was identified during puncture of the epidural space, and a catheter was placed after re-puncture. The postoperative course was normal except for incisional pain. The patient complained of slight neck stiffness on the second postoperative day. Magnetic resonance imaging (MRI) was performed to ensure that there was no intracranial problem on the fourth postoperative day and showed a bilateral subdural hematoma. Increase in size of hematoma was shown on computed tomography (CT) on the ninth postoperative day. Epidural blood patch was performed. A decrease in the size of the hematoma was confirmed on the CT images on the 11th postoperative day, and the patient was discharged. The patient has not developed any additional symptoms.

Conclusions

We experienced a patient who developed a SDH without a remarkable headache. It may be better to perform brain imaging studies, even if the patient does not complain of headache.

Neurological complications of lumbar and cervical dural punctures with a focus on epidural injections

Background:

Various types of lumbar dural punctures may contribute to neurological injury. The etiologies of dural injury include; inadvertent dural punctures due to epidurals placed for labor anesthesia, epidural steroid injections (ESI/transforaminal TESI; approximately 9 million ESI performed in the US per year), deliberate placement of intradural pain devices, and spontaneous cerebrospinal fluid (CSF) fistulas. Resulting neurological complications may include; spinal headaches/intracranial hypotension, subdural hematomas, and 6^th nerve cranial palsies. Furthermore, uniquely in the cervical spine, inadvertent cervical dural punctures attributed to cervcial ESI (CESI) may lead to intramedullary spinal cord injuries (e.g. resulting in monoparesis to quadriplegia) or spinal cord strokes due to intravascular/vertebral artery injections.

Methods/Results:

In 8 studies, inadvertent lumbar dural punctures contributed to intracranial hypotension, subdural hematomas, and double vision/6^th cranial nerve palsies. In 5 of the 6 studies, inadvertent dural punctures occurring during CESI were responsible for intramedullary spinal cord injuries, or direct intravascular/vertebral injections resulting in monoplegia/quadriplegia.

Conclusions:

Inadvertent lumbar dural punctures led to multiple neurological complications including intracranial hypotension, subdural hematomas, and double vision/6^th cranial nerve palsies. Uniquely, inadvertent cervical dural punctures solely due to CESI directly resulted in intramedullary spinal cord injuries or cord stroked and monoplegia/quadriplegia attributed to intravascular/vertebral artery injections. The potential neurological risks/complications/adverse events attributed to lumbar and cervical ESI must be taken into account before spine surgeons and others order these procedures.

Subdural haematoma following infant spinal anaesthesia

INTRODUCTION

Subdural haematoma (SDH) is rare following spinal anaesthesia and has not been reported previously in an infant. Non-accidental injury is the commonest cause of subdural haematoma in infants.

METHODS

We describe two cases of SDH following spinal anaesthesia in infants.

RESULTS

In both cases, forensic investigation was commenced and no evidence of child abuse was found. Both children are well 2 years after diagnosis.

CONCLUSION

Paediatric health workers should be aware of the possibility of SDH after spinal anaesthesia and consider this as a differential diagnosis when investigating possible non-accidental injury in an infant.

Haemostasis and safety measures before lumbar puncture in the haematology ward: the Danish routines

BACKGROUND/AIMS

Thrombocytopenia and the increasing use and variety of antithrombotic drugs is a challenge prior to lumbar puncture. This study examined the Danish haematology practice regarding drug pausation, assessment of haemostasis and whether fundoscopy is a routine safety measure.

METHODS

An online survey with questions pertaining to precautions of haemostasis and application of fundoscopy was sent by e-mail to all 12 haematology wards in Denmark.

RESULTS

Eleven sites participated. Five (45%) reported no pausation of antiplatelet drugs at all. The mean platelet limit prior to lumbar puncture was 50 × 10(9)/l (range 10-50 × 10(9)/l). Seven (64%) sites had an international normalised ratio limit of 1.5, and the remaining 4 had values between 1.0 and 2.5. Two (18%) reported occasional use of thromboelastography or platelet analysis to assess the bleeding risk. Fundoscopy is routinely performed in 4 (36%) departments.

CONCLUSION

We report considerable variation in the routine handling of antithrombotics and thrombocytopenia in patients set for lumbar puncture in Danish haematology departments. The diversity may be explained by and related to different opinions in the literature. Common national guidelines are warranted and there is a need for studies to establish an evidence-based approach for the management of patients at risk of bleeding when lumbar puncture or another invasive procedure is indicated.

Simultaneous appearance of cerebral venous thrombosis and subdural hematomas as rare cause of headache in puerperium following epidural analgesia: a case report

The aim of this study is to report the first case of simultaneous appearance of cerebral venous thrombosis (CVT) and bilateral subdural hematomas (SDHs) following epidural analgesia for labor and delivery and to point out the difficulty of establishing such a diagnosis in the presence of postpartum headache. A 26-year old primigravida with a history of epilepsy received epidural analgesia for delivery. Three days after the uneventful spontaneous vaginal delivery she complained about the headache. Patient responded very well to the pain medication and oral hydration, and the headache was relieved. Ten days after the delivery, the headache reoccurred, and an epidural blood patch was performed that successfully relieved her symptom. Stronger progressive headache with nausea reappeared two days later and the parturient was readmitted to hospital. Urgent neuroimaging examinations detected CVT of right the transverse sinus, ipsilateral cortical veins, and partially occluded superior sagittal sinus, as well as bilateral subacute/chronic SDHs. The treatment of the patient with low molecular weight heparin and antiaggregation therapy was effective. In this case, the diagnosis was delayed because of atypical clinical presentation and potentially confounding events (epidural analgesia and assumption that it was a case of PDPH). It is important to carefully observe patients in such conditions and promptly conduct suitable diagnostic tests. Otherwise, unrecognized intracranial complications and delay of appropriate therapy could be life-threatening.

[Post-dural headache with seven months duration: case report]

BACKGROUND AND OBJECTIVES

Post-dural puncture headache is a possible and expected complication in a small percentage of cases after spinal anesthesia. The objective of the current report was to describe the therapeutic conduct in a case of post-dural puncture headache with seven months of evolution.

CASE REPORT

A 40-year-old healthy female who complained of headache for seven months, which began after spinal anesthesia. She reported that some analgesics and decubitus position provided partial pain relief. An epidural blood patch was performed, with complete resolution of pain. She was discharged without complaints.

CONCLUSIONS

This case demonstrated that the epidural blood patch was effective in the treatment of chronic post-dural puncture headache in a case with seven-month evolution.

Atraumatic lumbar puncture needles: after all these years, are we still missing the point?

BACKGROUND

Cutting needles remain the most commonly used needle design for lumbar puncture in the neurology community, although atraumatic (noncutting) needles have become common and popular for anesthesiologists performing spinal anesthesia.

REVIEW SUMMARY

The use of atraumatic spinal needles for lumbar puncture has been shown to significantly reduce the incidence of postdural puncture headache compared with cutting needles, without loss of efficacy or ease of use.

CONCLUSION

The use of noncutting or pencil-point spinal needles should become the standard for performing diagnostic lumbar puncture.

Anesthesia complications in the birthplace: is the neuraxial block always to blame?

This article highlights the common and some of the very serious complications that may occur following neuraxial analgesia for labor and delivery, including headache, backache, infection, hypotension, and hematoma. Total spinal and failed block also are discussed, as are complications unique to epidural anesthesia, such as the intravascular injection of large volumes of local anesthetic (causing seizure or cardiac arrest) and accidental dural puncture.

[Cranial subdural haematoma after spinal anaesthesia treated by blood patch]

The authors report a case of subdural haematoma after spinal anaesthesia. A 36-year-old woman underwent phlebectomy under spinal anaesthesia. Two days later, she complains of severe headache without neurological signs, not responding to bed rest and analgesics. Magnetic resonance imaging showed a small acute subdural haematoma in the right parieto-occipital region. On the forth day, she was given a blood-patch, which improved rapidly the patient. Recovery was complete.

Acute Intracranial Subdural Hematoma After Epidural Steroid Injection: A Case Report

OBJECTIVE

Conservative treatment of lumbar radiculopathy includes bed rest, oral medications, physical therapy, spinal manipulation, mobilization, and epidural steroid injections. Intracranial subdural hematoma after accidental dural puncture is a rare and life-threatening complication of epidural steroid injections. In this report, we present a case of subacute intracranial subdural hematoma that developed after epidural steroid injection.

CLINICAL FEATURES

A 40-year-old man was admitted to our clinic with severe persistent headache and vomiting for 2 days after epidural steroid injection for right leg pain.

INTERVENTION AND OUTCOME

The patient was hospitalized for epidural steroid injection for right leg pain in our pain clinic and was discharged the same day. Twenty-four hours later, he started having a headache. Despite the use of oral analgesics, his headache worsened, and he began to vomit particularly in the upright position. Magnetic resonance imaging of the brain displayed a right frontal subdural hematoma. The headache was relieved after strict bed rest, intravenous hydration, and analgesics. The patient was discharged with full recovery after 1 week.

CONCLUSION

Intracranial subdural hematoma after accidental dural puncture during epidural steroid injection is a rare complication. Persistent headache should be evaluated carefully for possible intracranial hematomas.

Persistent postpartum headache from a chronic subdural hematoma after peridural anesthesia

BACKGROUND

Postpartum headache after peridural anesthesia is usually attributed to accidental perforation of the dura causing postlumbar puncture headache.

CASE

In a patient with persistent headache after peridural anesthesia for labor, a chronic subdural hematoma was diagnosed 5 weeks postpartum.

CONCLUSION

Caution is warranted in patients with peridural anesthesia for labor who present with unusually persistent headache.

Inadvertent dural puncture during attempted thoracic epidural catheter placement complicated by cerebral and spinal subdural hematoma

Minor complications of inadvertent dural puncture during attempted epidural anesthesia are common, related to the size of the needle and the incidence of postdural puncture headache. Serious complications are much less common. We report a case where inadvertent dural puncture with an 18-gauge epidural needle was associated with the creation of intracranial and spinal subdural hematoma.

Does postdural puncture headache left untreated lead to subdural hematoma? Case report and review of the literature

The patient was a 39-year-old pregnant woman who was scheduled for cesarean section. Spinal anesthesia was induced using a 26-gauge needle with an atraumatic bevel. Postoperatively, the patient developed cranial subdural hematoma manifesting as severe non-postural headache, associated with right eye tearing, fifth cranial nerve palsy and left hemiparesis. The diagnosis was confirmed by computed tomography scan. The patient was managed by careful neurological follow-up associated with conservative treatment and recovered fully after 12 weeks. Our report reviews the literature on 46 patients who developed a postdural puncture headache complicated by subdural hematoma following spinal or epidural anesthesia. It is possible that postdural puncture headache left untreated may be complicated by the development of subdural hematoma. Patients developing a postdural puncture headache unrelieved by conservative measures, as well as the change from postural to non-postural, require careful follow-up for early diagnosis and management of possible subdural hematoma.

Correlation of Adverse Neurological Outcomes with Increasing Volumes and Delayed Administration of Autologous Epidural Blood Patches for Postdural Puncture Headaches

INTRODUCTION

Epidural blood patches (EBPs) usually afford rapid and successful treatment outcomes for postdural puncture headaches (PDPH) with few adverse sequelae.

PATIENTS AND METHODS

In order to identify potential risk factors for any adverse outcomes of EBP, a Medline search, 1966 to the present, of case reports and series of any adverse outcomes following EBP for PDPH was conducted. The literature search identified 26 patient cases with 21 cases defined as adverse neurological outcomes, and further stratified as compression or noncompression syndromes, and five cases defined as persistent cranial nerve (CN) palsies. Cases were also stratified by age, sex, and blood volumes of EBP or delays in administration, and compared for statistically significant differences in continuous variables by unpaired, two-tailed t-tests and for significant correlations between predictor variables, including EBP volumes and delays in administration, and adverse neurological outcomes, by simple linear regression analysis.

RESULTS

There were no statistically significant sex differences in the mean ages or weights of the study population, or in the total volumes of autologous blood injected in EBPs. When the study population was compared for adverse neurological outcomes by compression or noncompression syndromes, patients experiencing compression syndromes received significantly more EBP volumes (35.36 mL) than patients experiencing noncompression (17.46 mL) syndromes (P = 0.025). Regression analysis confirmed a significant direct linear relationship between increasing EBP volumes and worsening adverse neurological outcomes (P = 0.008). In patients with CN palsies associated with PDPH and unrelieved by EBP, regression analysis again confirmed significant direct linear relationships between increasing days waited to perform EBP and increasing duration of CN palsies in months (P = 0.001).

CONCLUSIONS

Epidural blood patches for the management of PDPH, especially PDPH associated with CN palsies, should be administered as soon as the diagnosis of PDPH is made with lower volumes of autologous blood (< or =20 mL) to assure the best treatment outcomes.

Intracranial subdural hematoma after spinal anesthesia

Intracranial subdural hematoma is an exceptionally rare but life-threatening complication of spinal anesthesia. We report a case of intracranial subdural hematoma following spinal anesthesia for cesarean section in a 27-year-old woman. She developed a diffuse headache after surgery with a blood pressure of 220/140 mm Hg which was followed by generalized seizure activity. Her blood pressure remained high after medication with diazepam, nifedipine and magnesium sulfate. She remained unconscious with a Glasgow coma scale of 5. The cranial tomography revealed a subdural hematoma with diffuse cerebral edema and cerebral tentorial herniation. When a patient complains of postdural puncture headache and then has seizure activity, one should consider alternative diagnoses, including that of a subdural hematoma, and carry out a careful examination, including magnetic resonance imaging or computerized tomography scan.

Epidural blood patch placed in the presence of an unknown cervical epidural hematoma

We discuss a case detailing a favorable outcome of an epidural blood patch performed in the presence of an unknown cervical epidural hematoma. The case highlights the use of a spinal needle for epidural space confirmation, the importance of waiting for final consultation and radiologic testing results before therapeutic intervention when possible, and the use of an epidural blood patch, even in the setting of a known epidural hematoma.
