Abstract
Introduction Postoperative spinal epidural hematoma (PSEH) is a severe complication of spinal surgery that necessitates accurate and timely diagnosis. This study aimed to assess the accuracy of ultrasonography as an alternative diagnostic tool for PSEH after microendoscopic laminotomy (MEL) for lumbar spinal stenosis, comparing it with magnetic resonance imaging (MRI). Methods A total of 65 patients who underwent MEL were evaluated using both ultrasound- and MRI-based classifications for PSEH. Intra- and interrater reliabilities were analyzed. Furthermore, ethical standards were strictly followed, with spine surgeons certified by the Japanese Orthopaedic Association performing evaluations. Results Among the 65 patients, 91 vertebral segments were assessed. The intra- and interrater agreements for PSEH classification were almost perfect for both ultrasound (κ=0.824 [95% confidence interval (CI) 0.729-0.918] and κ=0.810 [95% CI 0.712-0.909], respectively) and MRI (κ=0.839 [95% CI 0.748-0.931] and κ=0.853 [95% CI 0.764-0.942], respectively). The results showed high concordance between ultrasound- and MRI-based classifications, validating the reliability of ultrasound in postoperative PSEH evaluation. Conclusions This study presents a significant advancement by introducing ultrasound as a precise and practical alternative to MRI for PSEH evaluation. The comparable accuracy of ultrasound to MRI, rapid bedside assessments, and radiation-free nature make it valuable for routine postoperative evaluations. Despite the limitations related to specific surgical contexts and clinical outcome assessment, the clinical potential of ultrasound is evident. It offers clinicians a faster, cost-effective, and repeatable diagnostic option, potentially enhancing patient care. This study establishes the utility of ultrasound in evaluating postoperative spinal epidural hematomas after MEL. With high concordance to MRI, ultrasound emerges as a reliable, practical, and innovative tool, promising improved diagnostic efficiency and patient outcomes. Further studies should explore its clinical impact across diverse surgical scenarios.

Abstract
Symptomatic spinal epidural hematoma (SEH) is a rare but well-documented complication in spine surgery, often associated with risk factors such as abnormal coagulation parameters, low platelets, excessive epidural bleeding, and inadequate hemostasis. While bilateral SEH is frequently described in the literature, unilateral SEH following spine surgery is seldom reported. We present a unique case of a unilateral neurological deficit resulting from an SEH following midline-sparing spine surgery due to unilateral drain placement in an 80-year-old male patient without comorbidities and normal coagulation parameters. Subsequent evacuation of the hematoma was done leading to gradual recovery of neurology. This emphasizes the importance of bilateral drain placement in such midline-sparing spine surgeries. This report underscores the significance of early SEH diagnosis and intervention, providing valuable insights into preventive measures and the need for a high index of suspicion in managing this potentially debilitating complication.

Abstract
OBJECTIVE Studies discussed few risk factors for specific patients, such as duration of disease; or surgical factors, such as duration and time of surgery; or C3 or C7 involvement, which could have led to the formation of hematomas (HTs). To investigate the incidence, risk factors especially the factors mentioned above, and management of postoperative HTs following anterior cervical decompression and fusion (ACF) for degenerative cervical diseases. METHODS Medical records of 1,150 patients who underwent ACF for degenerative cervical diseases at our hospital between 2013 and 2019 were identified and reviewed. Patients were categorized into the HT group (HT group) or normal group (no-HT group). Demographic, surgical and radiographic data were recorded prospectively to identify risk factors for HT. RESULTS Postoperative HT was identified in 11 patients, with an incidence rate of 1.0% (11 of 1,150). HT occurred within 24 hours postoperatively in 5 patients (45.5%), while it occurred at an average of 4 days postoperatively in 6 patients (54.5%). Eight patients (72.7%) underwent HT evacuation; all patients were successfully treated and discharged. Smoking history (odds ratio [OR], 5.193; 95% confidence interval [CI], 1.058-25.493; p = 0.042), preoperative thrombin time (TT) value (OR, 1.643; 95% CI, 1.104-2.446; p = 0.014) and antiplatelet therapy (OR, 15.070; 95% CI, 2.663-85.274; p = 0.002) were independent risk factors for HT. Patients with postoperative HT had longer days of first-degree/intensive nursing (p < 0.001) and greater hospitalization costs (p = 0.038). CONCLUSION Smoking history, preoperative TT value and antiplatelet therapy were independent risk factors for postoperative HT following ACF. High-risk patients should be closely monitored through the perioperative period. Postoperative HT in ACF was associated with longer days of first-degree/intensive nursing and more hospitalization costs.

Delayed Onset Postoperative Spinal Epidural Hematoma after Lumbar Spinal Surgery: Incidence, Risk Factors, and Clinical Outcomes. BIOMED RESEARCH INTERNATIONAL 2020; 2020:8827962. [PMID: 33426075 PMCID: PMC7775149 DOI: 10.1155/2020/8827962] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 12/12/2020] [Accepted: 12/20/2020] [Indexed: 02/06/2023]
Abstract
Background Posterior spinal epidural haematoma (PSEH) often develops within 24 hours after surgery. On rare occasions, PSEH occurs after 3 days and up to two weeks and is classified as delayed-onset PSEH. Due to its rarity, previous studies have only described the clinical features, whereas risk factors have not been assessed. Methods Patients who developed PSEH requiring haematoma evacuation between December 2013 and January 2020 were included and divided into the early-onset (group A) and delayed-onset (group B) groups based on the time of symptom onset (>72 hours). For each PSEH patient, 3 controls (group C) who did not develop PSEH in the same period were randomly selected. Clinical features were compared among the three groups, and multiple logistic regression analysis was performed to identify the risk factors for groups A and B. Results Thirty-two patients (0.35%) were identified as having early-onset PSEH (occurring at 10.68 ± 11.5 h), and 15 (0.16%) patients had delayed-onset PSEH (occurring at 130.60 ± 61.78 h). When comparing groups A and B, group A showed a higher rate of multilevel procedures, lower drainage, lower APTT, and higher JOA score at discharge. Multiple logistic regression analysis identified multilevel procedures (OR: 5.62, 95% CI: 1.84-17.25), postoperative systolic blood pressure (SBP) (OR: 1.10, 95% CI: 1.06-1.15), and abnormal coagulation (OR: 5.68, 95% CI: 1.74-18.52) as independent risk factors for group A, whereas postoperative SBP (OR: 1.10, 95% CI: 1.04-1.16) and previous spinal surgery (OR: 4.74, 95% CI: 1.09-20.70) at the same level were risk factors for group B. Conclusions Our study revealed that the overall incidence of delayed-onset PSEH was 0.16% in posterior lumbar spinal surgery and that its risk was different from that of early-onset PSEH. If patients with such risk factors develop neurological deficits 3 days after initial surgery, surgeons should be aware of the possibility of delayed-onset PSEH.

Abstract
BACKGROUND Symptomatic post-operative lumbar epidural hematoma (PLEH) is a complication of lumbar spine surgery that can cause permanent neurologic consequences through compression of the cauda equina and nerve roots. QUESTIONS/PURPOSES We sought to investigate the incidence, timing, and risk factors for symptomatic epidural hematomas following posterior lumbar decompression, as well as to identify additional post-operative complications associated with symptomatic lumbar epidural hematomas. METHODS Elective lumbar spine procedures were identified in the National Surgical Quality Improvement Program (NSQIP) database between 2012 and 2016. Analyzed predictors of reoperation or readmission within 30 days for symptomatic PLEH included demographics, comorbidities, pre-operative laboratory values, peri-operative characteristics, and post-operative complications. RESULTS There were 75,878 cases included in the analysis. The incidence rate of symptomatic PLEH was 0.27% (n = 206), 54.4% (n = 112) of which occurred within 5 days of the procedure. Increased age, obesity (body mass index of 35 or higher), peri-operative transfusion, multilevel surgery (two or more levels), dural tear repair, and microscope use were independently associated with PLEH. Post-operative complications associated with PLEH included surgical site infection and urinary tract infection. CONCLUSIONS Readmission or reoperation for symptomatic PLEH following elective lumbar spine surgery is rare and can occur many days or weeks after a procedure. There are modifiable risk factors for PLEH and associated additional post-operative complications that physicians should be suspicious of following posterior lumbar decompression.

Abstract
Delayed post-operative spinal epidural haematoma (DPSEH) is diagnosed when the onset of symptoms is more than three days from the index surgery. DPSEH is a rare but serious complication of spinal surgery. Missed diagnosis will result in irreversible neurological deficit which may lead to permanent disabilities. We report two cases of DPSEH who presented with worsening neurological deficit four days after the index surgery. Magnetic resonance imaging (MRI) showed the presence of an epidural haematoma compressing the spinal cord. Surgical evacuation of haematoma were performed for both patients. Both patients experienced neurological improvement. Surgeons should have high index of suspicion to identify delayed onset of spinal epidural haematoma (SEH) and timely intervention should be taken to avoid irreversible neurological damage.

Abstract
OBJECTIVE The aim of this study was to develop a new radiological classification system for postoperative spinal epidural hematoma (SEH) using magnetic resonance imaging (MRI) and to determine the correlation of this classification system with clinical and radiological outcomes. METHODS This prospective study included a total of 245 consecutive patients (126 females, 119 males; mean age=72 years; age range=39-91 years) with single level spinal stenosis who were treated by microendoscopic decompressive laminotomy (MEDL). MRI was performed for all patients 24 hours postoperatively and at 12 months. SHEs were categorized into four grades using our new MRI-based classification system based on the measurement of dural sac area: Grade A, small hematoma with a round shape; grade B, small hematoma that show no round shape; grade C, moderate hematoma; grade D: severe hematoma. Patients were then divided into four groups according to their hematoma grades, Group A, 107 patients with grade A hematomas; group B, 47 with grade B; group C, 67 with grade C; group D, 24 with grade D. Also, patients who had neurological deterioration or who pain resistant to medical treatment were treated surgically, and those were assigned to group H+(14 patients). The study, therefore, contained five groups. Clinical evaluation was done using Japanese Orthopaedic Association (JOA) score preoperatively and at 12 months postoperatively. RESULTS No significant difference existed among groups in the preoperative median measurement of the dural sac area, which were 0.90 cm2 in group A, 0.80 cm2 in group B, 0.70 cm2 in group C, 1.1 cm2 in group D, and 0.80 cm2 in group H+ (p=0.076). At the postoperative 12-month measurement, no significant difference was noted among groups A (2.05 cm2), B (1.80 cm2 ), and H+ (1.90cm2) (A vs B: p=0.891, A vs H+: p=0.089, B vs H +: p=0.933). The measurements were greater in groups A and B than in groups C and D (p<0.05). Also, larger dural sac areas were determined in group H+ (1.90cm2) compared to Groups C (1.80 cm2) and D (1.60 cm2) but the difference reached no statistical significance (p=0.078). In preoperative JOA scores, there were no significant differences among groups (p>0.05). At 12-month JOA scores, no significant difference was observed between groups A and B (p=0.061) and between groups C and D (p=0.511). The scores were higher in groups A and B than in groups C and D (p<0.05). CONCLUSION It seems that the narrower the preoperative dural sac area, the better the clinical symptoms of the patients with SEHs based on our new MRI-based classification system. This classification may be useful to predict the clinical status of these patients at one-year follow-up. LEVEL OF EVIDENCE Level IV, Diagnostic study.

Abstract
OBJECTIVE Postoperative epidural hematoma (PEDH) after minimally invasive lumbar laminectomy (MILL) can lead to significant morbidity and healthcare cost. The incidence is not well characterized in the literature as compared with traditional open techniques. Our aim was to define the incidence of PEDH after MIS lumbar decompression procedures and evaluate strategies for reduction of PEDH. PATIENTS AND METHODS A retrospective review of a prospectively collected database was queried from January 2013 to September 2018 for all patients that underwent a minimally invasive lumbar laminectomy or laminotomy, with or without discectomy, for which the goal was decompression alone. Charts were reviewed to see the operation type and whether the patient developed a postoperative epidural hematoma. RESULTS 1004 cases were identified and reviewed. The overall PEDH rate was 1.4 % (14/1004). 78.5 % (11/14) of cases involved at least a single level laminectomy. 21.4 % (3/14) involved a laminotomy alone or with discectomy. 64.3 % (9/14) of patients presented with a neurological deficit. CONCLUSIONS The rate of PEDH after MIS lumbar decompression procedures is 1.4 %. A majority of patients presented with a neurological deficit.

Orthop Surg 2019; 12:67-73. [PMID: 31849183 PMCID: PMC7031588 DOI: 10.1111/os.12583] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2019] [Revised: 11/03/2019] [Accepted: 11/04/2019] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVE The aim of the present study was to investigate whether an innovative way of administering tranexamic acid (TXA), that is, injecting it retrogradely through the drain and clamping it for 1 h, can reduce postoperative bleeding after degenerative lumbar scoliosis surgery. METHODS Sixty degenerative lumbar scoliosis patients who underwent posterior lumbar decompression with fusion of three or more levels were retrospectively enrolled and categorized into three groups (TXA, Gelfoam, and control groups). The demographic distribution, operative parameters, length and amount of Hemovac drainage, blood transfusion rate, length of stay, laboratory results (complete blood count and coagulogram), and the postoperative complications were collected and analyzed. RESULTS The age of patients in the Gelfoam group was significantly younger than in the TXA and control groups (59.75 ± 6.95 vs 66.10 ± 8.80, P = 0.016 and 59.75 ± 6.95 vs 67.90 ± 5.33, P = 0.000, respectively). There were no significant differences in sex, body mass index, comorbid medical status, and operation level between each of the two groups. The three groups did not differ significantly in estimated blood loss during surgery, the mean red blood cell transfusion requirement during hospitalization, and the entire perioperative allogenic blood transfusion rate. The postoperative total blood loss and total drainage were lower in the TXA group than in the control group (1027.14 ± 466.56 vs 1390.07 ± 314.85 mL, P = 0.006; 322.20 ± 187.32 vs 605.50 ± 184.70 mL, P = 0.000, respectively). The length of drainage retention in the TXA group was significantly shorter than in the Gelfoam and control groups (46.10 ± 9.00 vs 68.00 ± 12.31 h, P = 0.000 and 46.10 ± 9.00 vs 76.40 ± 10.97 h, P = 0.000, respectively). The TXA and Gelfoam groups also had significantly shorter hospital stays than the control group (7.50 ± 0.95 vs 9.80 ± 2.44 days, P = 0.000, and 7.90 ± 1.16 vs 9.80 ± 2.44 days, P = 0.003, respectively). At discharge, the mean hemoglobin and hematocrit level were significantly higher in the TXA group compared with the control group (11.77 ± 1.78 g/dL vs 10.67 ± 0.94 g/dL, P = 0.002; 34.82 ± 3.57% vs 31.79 ± 3.85%, P = 0.014). No significant difference was identified with respect to prothrombin time, activated partial thromboplastin time, and D-dimmer among groups (P > 0.05). The three groups were comparable in wound problem incidences. Symptomatic deep vein thrombosis and pulmonary embolism were not observed in this study. CONCLUSION Topical injection of TXA retrogradely via a drain at the end of a degenerative lumbar scoliosis operation and clamping the drain for an hour can effectively decrease the postoperative blood loss and the length of hospitalization without increasing the complication rate.

Abstract
Introduction Symptomatic postoperative hematoma after spine surgery is a rare but serious complication. The objective of this study was to investigate the incidence and clinical features of symptomatic postoperative hematoma after spine surgery. Methods We retrospectively identified 10,680 patients who underwent spine surgery between 2002 and 2012 in nine hospitals. We reviewed the incidence of postoperative hematoma and its clinical features, including time before onset, main symptoms, and neurological outcomes. Results The overall incidence of symptomatic postoperative hematoma after spine surgery was 0.4% (45/10,680). Postoperative hematoma was more frequent after thoracic spine surgery than after cervical or lumbar surgery. The onset of postoperative hematoma occurred at an average of 2.6 days (range 0-14 days) postoperatively. The chief symptoms caused by postoperative hematoma after spine surgery were tetra/paraplegia in 30 patients, hemiplegia in eight patients, intractable pain in five patients, and airway dysfunction in two patients. Surgical evacuation of the spinal epidural hematoma resulted in improvement of at least one grade in 35 patients, while four patients had complete motor paralysis even after evacuation surgery. Conclusions We report the clinical details of 45 patients with postoperative hematoma after spine surgery. This information could assist surgeons to make a prompt diagnosis and perform early evacuation surgery for postoperative hematoma following spine surgery.

Abstract
STUDY DESIGN A retrospective observational study. OBJECTIVE To investigate the incidence and clinical features of symptomatic postoperative spinal epidural hematoma (PSEH) with regard to spinal level and to compare early and delayed onset cases. SUMMARY OF BACKGROUND DATA PSEH is a serious complication of spinal surgeries. The difference in clinical manifestations between early and delayed PSEH remains unclear. METHODS Patients who underwent spinal surgeries between 1999 and 2013 at our institution, were reviewed through their medical records. For patients with PSEH, the incidence, duration to onset, duration from onset to evacuation, symptoms, recovery rate (American Spinal Injury Association grade), neurological outcomes, comorbidities, and preoperative use of anticoagulant drugs were examined. We next compared patients with early onset PSEH (onset until day 3) versus delayed onset (onset day 4 or later) regarding these clinical factors. RESULTS Fourteen patients (0.42%, 14/3371) developed symptomatic PSEH. Initial symptoms were observed between 0 and 7 days (mean 2.6 ± 2.4 d) and almost half (43%, 6/14) occurred during the delayed phase (mean 5.0 ± 1.1 d postsurgery). Paralysis was the predominant symptom in patients with cervical and thoracic surgeries (100%, 6/6), whereas severe pain was most frequent in patients with lumbar procedures (63%, 5/8) (P = 0.019). No significant differences were identified between early and delayed groups. Neurological outcome was good in 10 cases, partial in two cases, and poor in two cases. CONCLUSION The frequency was consistent in every spinal region, and the symptoms due to PSEH were correlated with spinal level. Almost half the cases were diagnosed after a delay (day 4 or later), which supports the necessity to follow up patients with spinal surgeries more carefully for a week or so and to educate patients and comedical staff about the possibility of delayed hematoma disorders in order not to defer timely intervention. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVE Postoperative hematoma is a rare and dangerous complication of cervical spine surgery. The aim of this study was to investigate the incidence and related factors of postoperative hematoma, and to report on 15 cases at our institution over a 6-year period. METHODS Fifteen cases of postoperative hematoma were retrospectively identified. We investigated their neurological outcomes, characteristics, and surgical data, and identified risk factors associated with postoperative (PO) hematoma. Patients with hematoma were compared to those with no hematoma, in order to identify risk factors. RESULTS Retropharyngeal hematomas developed in seven cases and epidural hematomas in eight. The total incidence of postoperative hematoma was 1.2%: 0.5% retropharyngeal hematomas and 0.6% spinal epidural hematomas. At time of onset, the severity of paralysis was assessed as grade B in one case, grade C in six cases, and grade D in eight cases. Risk factors for PO hematoma were: (1) presence of ossification of the posterior longitudinal ligament (OPLL) (P<0.001); (2) longer operative duration (P=0.048); (3) greater number of surgical levels (P=0.02); and (4) higher body mass index (BMI; P=0.035). There was no significant difference in modified Japan Orthopedic Association scores between the hematoma group and non-hematoma group (P>0.05). CONCLUSION Precise preoperative preparation and systematic evaluation are central to successful management of PO hematoma after anterior cervical surgery. Risk factors for PO hematoma include multilevel decompression, OPLL, higher BMI, and longer operation time.

Abstract
There is a paucity of literature describing the management of recurrent symptomatic postoperative epidural hematoma or uncontrollable intraoperative hemorrhage in posterior spine surgery. Traditional management with hematoma evacuation and wound closure over suction drains may not be effective in certain cases, and it can lead to recurrence and neurological injury. The authors report 3 cases of recurrent symptomatic postoperative epidural hematoma successfully managed with novel open-wound negative-pressure dressing therapy (NPDT), as well as 1 case of uncontrollable intraoperative hemorrhage that was primarily managed with the same technique. The 3 patients who developed a postoperative epidural hematoma became symptomatic 2-17 days after the initial operation. All 3 patients underwent at least 1 hematoma evacuation and wound closure over suction drains prior to recurrence with severe neurological deficit and definitive management with NPDT. One patient was managed primarily with NPDT for uncontrollable intraoperative hemorrhage during posterior cervical laminectomy. All 4 patients had significant risk factors for postoperative epidural hematoma. NPDT for 3-9 days with delayed wound closure was successful in all patients. The 3 patients with recurrent symptomatic postoperative epidural hematoma had significant improvement in their severe neurological deficit. None of the patients developed a postoperative wound infection, and none of the patients required transfusion due to NPDT. NPDT with delayed wound closure may be an option in certain patients, when wound closure over suction drains is unlikely to prevent further neurological injury.

Abstract
A 56-year-old man underwent cervical laminoplasty for cervical spondylosis. On the 7th postoperative day, he suddenly felt severe neck pain, and tetraplegia developed rapidly over 1.5 hrs. Computed tomography demonstrated a huge hematoma compressing the cervical spinal cord. Clot was evacuated 3 hrs after the onset of symptoms. The patient’s postoperative course was uneventful. His blood pressure could not be properly controlled in the perioperative period. Surgeons should keep in mind that delayed postoperative spinal epidural hematoma (DPSEH) can occur more than a week after surgery, and meticulous blood pressure control is important for more than a week after a spinal operation.

Abstract
OBJECTIVE We aimed to characterize the occurrence of postoperative hematoma (POH) after neurosurgery overall and according to procedure type and describe the prevalence of possible confounders. METHODS Patient data between 2010 and 2012 at the Department of Neurosurgery in Helsinki University Hospital were retrospectively analyzed. A data search was performed according to the type of surgery including craniotomies; shunt procedures, spine surgery, and spinal cord stimulator implantation. We analyzed basic preoperative characteristics, as well as data about the initial intervention, perioperative period, revision operation and neurologic recovery (after craniotomy only). RESULTS The overall incidence of POH requiring reoperation was 0.6% (n = 56/8783) to 0.6% (n = 26/4726) after craniotomy, 0% (n = 0/928) after shunting procedure, 1.1% (n = 30/2870) after spine surgery, and 0% (n = 0/259) after implantation of a spinal cord stimulator. Craniotomy types with higher POH incidence were decompressive craniectomy (7.9%, n = 7/89), cranioplasty (3.6%, n = 4/112), bypass surgery (1.7%, n = 1/60), and epidural hematoma evacuation (1.6%, n = 1/64). After spinal surgery, POH was observed in 1.1% of cervical and 2.1% of thoracolumbar operations, whereas 46.7% were multilevel procedures. 64.3% of patients with POH and 84.6% of patients undergoing craniotomy had postoperative hypertension (systolic blood pressure >160 mm Hg or lower if indicated). Poor outcome (Glasgow Outcome Scale score 1-3), whereas death at 6 months after craniotomy was detected in 40.9% and 21.7%. respectively, of patients with POH who underwent craniotomy. CONCLUSIONS POH after neurosurgery was rare in this series but was associated with poor outcome. Identification of risk factors of bleeding, and avoiding them, if possible, might decrease the incidence of POH.

Abstract
OBJECTIVES This paper aims to determine whether the use of Tranexemic Acid (TXA) - soaked absorbable gelatin sponge could more effectively reduce post-operative blood loss and blood transfusion requirements among low-risk adult patients undergoing lumbar spine surgery. METHODS A total of 90 consecutive patients undergoing surgery for multilevel posterior lumbar degenerative procedures were prospectively randomized into one of three groups: - TXA Soaked Gelfoam group, absorbable gelatin sponge group or control group. Demographic distribution, total drain output, blood transfusion requirement, length of hospital stay, the number of readmissions, and postoperative complications were analyzed. RESULTS In the TXA Soaked Gelfoam, Gelfoam, and control groups, the respective hemovac drainage at the first 8h postoperatively was 81.06±61.21, 166.73±76.76, and 155.67±92.94ml respectively. The second 8h period drainage for the same groups postoperatively was 46.67±40.09, 55.10±43.43, and 82.50±56.67ml and 23.73±25.56, 32.43±25.81 and 44.20±32.44ml for the third 8h period postoperatively. The duration of the post-operative drain left in the TXA Soaked Gelfoam group was significantly shorter than the Gelfoam and control groups (p=0.019 and 0.000, respectively). The TXA Soaked Gelfoam and Gelfoam also had a significantly shorter hospital stay than the control group (p=0.014, and 0.036, respectively). No patient developed adverse reactions attributable to the tranexamic acid soaked absorbable gelatin sponge. CONCLUSIONS TXA-soaked absorbable gelatin sponge is a safe, effective treatment for reduction of post-operative blood loss and blood transfusions among low-risk adult patients undergoing lumbar spine surgery.

Abstract
Study Design Case report and literature review. Objective Multiregional spinal stenosis (MRSS) has not been described in the English literature, although a few studies report the concept of tandem spinal stenosis. Due to the concurrent spinal stenosis occurring in three separate regions of the spine, clinical presentation of MRSS may be less distinct, and its surgical treatment priorities and challenges differ from single-region spinal stenosis. The purpose of this article is to describe a new concept and a rare case of MRSS as separated segments of spinal stenosis in the cervical, thoracic, and lumbar spine. Methods A retrospective case description of MRSS and surgical strategies used in managing such extensive multiregional stenosis and its potential complications. Results A novel surgical strategy using a combination of laminectomies with fusion and laminoplasty without fusion to treat this patient with such extensive cervical to thoracic myelopathic cord compression is described. Initial good recovery after cervical cord decompression was followed by a delayed recurrence of symptoms from thoracic cord compression. The subsequent thoracic surgical decompression, its complications and management, and patient recovery are discussed with a literature review highlighting the possible mechanisms for postoperative loss of neurologic function after thoracic decompression. Conclusion MRSS is a rare cause of extensive compression of multiple regions of the spinal cord. To the best of the authors' knowledge, this report is the first to use the term multiregional spinal stenosis to describe this new emergent clinical entity, surgical management strategies, and potential complications.

Abstract
OBJECT Patients who develop a lower-extremity neurological deficit after lumbar laminectomy present a diagnostic dilemma. In the setting of a neurological deficit, some surgeons use MRI to evaluate for symptomatic compression of the thecal sac. The authors conducted a prospective observational cohort study in patients undergoing open lumbar laminectomy for neurogenic claudication to document the MRI appearance of the postlaminectomy spine and to determine changes in thecal sac diameter caused by the accumulation of epidural fluid. METHODS Eligible patients who were candidates for open lumbar laminectomy for neurogenic claudication at a single neurosurgical center between August 2007 and June 2009 were enrolled. Preoperative and postoperative MRI of the lumbar spine was performed on the same MRI scanner. Postoperative MRI studies were completed within 36 hours of surgery. Routine clinical and surgical data were collected at the preoperative visit, during surgery, and postoperatively. Images were interpreted for the signal characteristics of the epidural fluid and for thecal diameter (region of interest [ROI]) by 2 blinded neuroradiologists. RESULTS Twenty-four patients (mean age 69.7 years, range 30-83 years) were enrolled, and 20 completed the study. Single-level laminectomy was performed in 6 patients, 2-level in 12, and 3-level in 2. Preoperative canal measurements (ROI) at the most stenotic level averaged 0.26 cm(2) (range 0.0-0.46 cm(2)), and postoperative ROI at that same level averaged 0.95 cm(2) (range 0.46-2.05 cm(2)). The increase in ROI averaged 0.69 cm(2) (range 0.07-1.81 cm(2)). Seven patients (35%) had immediate postoperative weakness in at least 1 muscle group graded at 4+/5. The decline in examination was believed to be effort dependent and secondary to discomfort in the acute postoperative period. Those with weakness had smaller increases in ROI (0.51 cm(2)) than those with full strength (0.78 cm(2), p = 0.1599), but none had evidence of worsened thecal compression. On the 1st postoperative day, 19 patients were at full strength and all patients were at full strength at their 15-day follow-up. The T1-weighted epidural fluid signal was isointense in 19 of the 20 patients. The T2-weighted epidural fluid signal was hyperintense in 9, isointense in 4, and hypointense in 7 patients. CONCLUSIONS Immediately after lumbar laminectomy, the appearance of the thecal sac on MRI can vary widely. In most patients the thecal sac diameter increases after laminectomy despite the presence of epidural blood. In this observational cohort, a reduction in thecal diameter caused by epidural fluid did not correlate with motor function. Results in the small subset of patients where the canal diameter decreased due to epidural fluid compression of the thecal sac raises the question of the utility of immediate postoperative MRI.

Abstract
We present a rare case of delayed onset of epidural hematoma after lumbar surgery whose only presenting symptom was vesicorectal disturbance. A 68-year-old man with degenerative spinal stenosis underwent lumbar decompression and instrumented posterolateral spine fusion. The day after his discharge following an unremarkable postoperative course, he presented to the emergency room complaining of difficulty in urination. An MRI revealed an epidural fluid collection causing compression of the thecal sac. The fluid was evacuated, revealing a postoperative hematoma. After removal of the hematoma, his symptoms disappeared immediately, and his urinary function completely recovered. Most reports have characterized postoperative epidural hematoma as occurring early after operation and accompanied with neurological deficits. But it can happen even two weeks after spinal surgery with no pain. Surgeons thus may need to follow up patients for at least a few weeks because some complications, such as epidural hematomas, could take that long to manifest themselves.

Abstract
BACKGROUND Despite meticulous hemostasis, persistent postoperative drain output following posterior cervical spine procedures often necessitates a prolonged length of hospital stay. We sought to determine if thrombin-soaked absorbable gelatin compressed sponge can decrease postoperative drain output and the length of hospital stay after multilevel posterior cervical spine surgery. METHODS We performed a retrospective analysis of forty-three pairs of patients who had undergone either posterior cervical decompression and/or fusion of three or more levels by the same surgeon. The patients were matched according to intraoperative blood loss, age, sex, and number of involved levels. Control patients were managed between 2004 and 2007, whereas study patients were managed between 2008 and 2011. The only variable between the study and control groups was that, in the study group, absorbable gelatin compressed sponge was soaked in thrombin and applied over the exposed spine before wound closure. A subfascial drain was used in all patients. Total drain output, time for the drainage to decrease to <30 mL per eight-hour shift (at which point the drain was discontinued), the length of stay, the number of readmissions, and postoperative complications were analyzed. RESULTS Total drain output averaged 93 mL in the study group and 204 mL in the control group (p < 0.0001). The average time for the drainage to decrease to <30 mL per eight-hour shift was 2.5 shifts in the study group and 4.4 shifts in the control group (p < 0.0001). Length of stay averaged 1.3 days (cumulative total, fifty-seven days) in the study group and 2.2 days (cumulative total, ninety-five days) in the control group (p < 0.0001). Persistent drain output was the primary reason preventing discharge on the first postoperative day. There were no infections, epidural hematomas, or readmissions within thirty days of discharge in either group. No patient developed adverse reactions attributable to the thrombin-soaked absorbable gelatin compressed sponge. CONCLUSIONS Application of thrombin-soaked absorbable gelatin compressed sponge at the end of multilevel posterior cervical spinal surgery significantly decreased postoperative drain output and consequent hospital stay. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Object
Neurological deterioration due to spinal epidural hematoma (SEH) is a rare but significant complication of spinal surgery. The frequency of hematoma evacuation after spinal surgery is reportedly 0.1%–3%. The objective of this study was to investigate the symptomatology of SEH and the frequency of evacuation for each surgical procedure after spinal decompression surgery.
Methods
This is a retrospective study of 26 patients who underwent SEH evacuation after spinal decompression surgery between 1986 and 2005. During this period, 6356 spinal decompression surgeries were performed. The factors studied were the frequency of SEH evacuation for each surgical procedure, symptoms, time to SEH evacuation, comorbidities, and neurological recovery.
Results
The frequency of SEH evacuation was 0.41% (26 of 6356) for all operations. The frequency for each surgical procedure was 0% (0 of 1568) in standard lumbar discectomy, 0.50% (8 of 1614) in lumbar laminectomy, 0.67% (8 of 1191) in posterior lumbar interbody fusion, 4.46% (5 of 112) in thoracic laminectomy, 0.44% (4 of 910) in cervical laminoplasty, and 0.21% (1 of 466) in cervical anterior spinal fusion. Nine patients had comorbidities involving hemorrhage. Spinal epidural hematoma evacuation was performed between 4 hours and 8 days after the initial operation. Whereas severe paralysis was observed within 24 hours in most patients undergoing cervical and/or thoracic surgery, half of the patients undergoing lumbar surgery had symptoms of SEH such as leg pain or bladder dysfunction after suction drain removal. The shorter the period to evacuation, the better were the results of neurological recovery.
Conclusions
Postoperative SEH was most frequent after thoracic laminectomy. In cervical and thoracic surgeries, symptoms of SEH were noted within 24 hours, mostly severe paralysis, and almost half of the lumbar surgery patients had symptoms after suction drain removal.

Jang JW, Lee JK, Seo BR, Kim SH. Spontaneous resolution of tetraparesis because of postoperative cervical epidural hematoma. Spine J 2010; 10:e1-5. [PMID: 21094465 DOI: 10.1016/j.spinee.2010.09.021] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2010] [Revised: 08/19/2010] [Accepted: 09/30/2010] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Symptomatic postoperative spinal epidural hematoma (PSEH) is a rare but potentially devastating postoperative complication, accounting for 0.1% to 0.2% of cases. PURPOSE To describe a patient with a PSEH that completely resolved, clinically and radiographically, without surgical treatment. STUDY DESIGN Case report and review of the literature. METHODS A 47-year-old man with no history of a bleeding disorder underwent anterior cervical interbody fusion for C5-C6 disc herniation. The dura was exposed through removal of the posterior longitudinal ligament, and extensive decompression of posterior osteophytes of C5 and C6 vertebral bodies was performed. The patient developed tetraparesis and respiratory distress rapidly in the postanesthesia care unit and was reintubated for assisted ventilation. The computed tomography (CT) scan revealed a very large ventral epidural hematoma compressing the dural sac from C1 to C6. RESULTS The patient was prepared for hematoma evacuation. However, the neurological symptoms and respiration problems began to resolve spontaneously before the surgery was started. The hematoma was markedly improved on the follow-up CT scan, and the patient was discharged 2 weeks after surgery without neurological deficit. CONCLUSIONS This case illustrates that an unpredictable extensive hematoma can occur after uneventful surgery of the cervical spine in low-risk patients. In case of the dural exposure with a creation of hidden and large epidural space, the spine surgeon must pay particular attention to the possibility of a PSEH during the early postoperative period.

Delayed Spinal Epidural Hematoma after En Block Spondylectomy for Vertebral Ewing's Sarcoma. Asian Spine J 2010; 4:118-22. [PMID: 21165315 PMCID: PMC2996623 DOI: 10.4184/asj.2010.4.2.118] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2010] [Revised: 03/15/2010] [Accepted: 03/18/2010] [Indexed: 01/30/2023] Open
Abstract
We report here on a case of a 23-year-old male who received en block spondylectomy for a vertebral Ewing's sarcoma at our hospital. Nine days after surgery, he presented with severe back pain and motor weakness of the lower extremities. Based on the physical examination and the computed tomography scan, he was diagnosed with acute cauda equina syndrome that was caused by compression from an epidural hematoma. His neurological functions recovered after emergency evacuation of the hematoma. This case showed that extensive surgery for a malignant vertebral tumor has a potential risk of delayed epidural hematoma and acute cauda equina syndrome and this should be treated with emergency evacuation.

Abstract
Spinal epidural hematoma is a rare condition that usually presents with acute, severe pain at the location of the hemorrhage, with radiation to the extremities. It can rapidly develop to include progressive and severe neurologic deficit. The pathophysiology often remains unclear. However, epidural hematoma in the lumbar spine is best described as the result of internal rupture of the Batson vertebral venous plexus. Clinical evaluation of pain control and neurologic deficit is the most important tool in early diagnosis. Currently, MRI is the diagnostic method of choice. Regardless of the setting, symptomatic spinal epidural hematoma is typically managed with urgent surgical decompression of the spinal canal.

Abstract
STUDY DESIGN Case report and literature review. OBJECTIVE Spinal epidural arteriovenous fistulas with secondary reflux into the perimedullary veins are rare. We report a patient who presented with delayed progressive congestive myelopathy after lumbar surgery. The pathophysiology and the anatomic basis for the responsible arteriovenous fistula are discussed. SUMMARY OF BACKGROUND DATA Delayed neurological deterioration after spinal surgery is uncommon. Epidural fistulae uncommonly may become symptomatic from an epidural hematoma, mass effect from distended veins, and rarely from a spinal dural arteriovenous fistula. We report on a patient with delayed progressive congestive myelopathy after lumbar surgery, and discuss the pathophysiology and the anatomical basis for the causative fistula. METHODS A 68-year-old man presented with progressive lower extremity weakness and sensory decrease, and loss of sphincter control 2 years after unilateral lumbar laminectomy and fusion for a disc herniation. MRI showed diffuse new cord edema and intradural perimedullary dilated vessels. Spinal angiography revealed an epidural arteriovenous fistula at the site of the previous laminectomy, with intradural perimedullary venous drainage. The fistula was successfully treated surgically and the patient experienced rapid and gradual neurologic improvement, being able to walk without a cane within 6 weeks of repair. RESULTS There are few causes of delayed neurologic deterioration after lumbar spinal surgery. Epidural fistulas are uncommon and rarely symptomatic, and when they are, it is usually from an epidural hematoma or mass effect from distended epidural veins. Epidural may rarely result in spinal dural arteriovenous fistulas, the most common spontaneous spinal arteriovenous condition, causing a congestive myelopathy characterized by lower extremity spasticity, sensory changes, and loss of sphincter control. CONCLUSION Delayed neurologic deterioration after spinal surgery is uncommon. Epidural arteriovenous fistulas with secondary intradural drainage, which are rare, should be considered.

Abstract
STUDY DESIGN Prospective clinical series with comparison to retrospectively collected data. OBJECTIVE To compare direct measures of postoperative hematoma volume against a new measure of hematoma effect on the thecal sac: the critical ratio. SUMMARY OF BACKGROUND DATA Asymptomatic epidural hematoma is common after lumbar surgery. Symptomatic patients demonstrate a typical progression from sharp peri-incisional pain to bilateral neurologic deficits. Little is known about what differentiates symptomatic and asymptomatic patients. Magnetic resonance imaging (MRI) measures of hematoma size or mass effect may correlate with postoperative symptoms. METHODS The study population consisted of 3 patient groups evaluated by MRI 2 to 5 days after lumbar decompression with or without fusion. Fifty-seven consecutive prospectively enrolled patients comprised the asymptomatic group. No patient developed severe postoperative pain or neurologic deficit. Search of our institutional database identified 4978 surgical patients within the last 24 months. Seventeen developed new postoperative symptoms. The painful group included 12 patients with severe peri-incisional pain without neurologic deficit. The cauda equina (CE) group included 5 patients with postoperative CE syndrome. Digital imaging software was used to calculate thecal sac cross sectional area on pre- and postoperative MRI at each level, hematoma volume, volume per level decompressed, and critical ratio for each patient. Critical ratio was defined as the smallest ratio of postoperative to preoperative cross sectional area within the lumbar spine. RESULTS.: The critical ratio was the only measure found to differ significantly (P < 0.05) among all 3 groups. Mean critical ratios were asymptomatic (0.8), painful (0.5), and CE (0.2). CONCLUSION The critical ratio correlates more closely with the presence or absence of postoperative symptoms than measures of hematoma volume, and is consistent with the clinical expectation that greater thecal sac compression may result in more severe symptoms. Few guidelines exist for postoperative lumbar MRI interpretation. The critical ratio is an important contribution.

Abstract
✓There are many potential risks associated with spinal deformity correction procedures including transient and/or permanent neurological deficits. Typically, neurological deficits caused by the surgical correction of spinal kyphosis occur acutely during surgery or immediately after surgery. Delayed postoperative neurological deficits are extremely rare.
The authors report a case of delayed neurological deficit that occurred 48 hours after surgical correction of thoracic hyperkyphosis. An 18-year-old man with myotonic dystrophy presented with a 110° T7–L1 kyphosis. The patient underwent an uneventful two-stage correction procedure of the hyperkyphotic deformity. First, anterior discectomies and fusion were performed from T-7 to L-1 using rib autograft, and all segmental vessels were preserved. Subsequently, on the same day, the patient underwent posterior Smith–Petersen osteotomies and T7–L2 pedicle screw fixation. Intact somatosensory and motor evoked potentials were maintained throughout both operations. Postoperatively, he remained neurologically intact without sequelae for nearly 48 hours. On postoperative Day 2, the patient developed delayed monoplegia of the left leg and sensory level loss below T-10.
Medical management enabled complete reversal of the patient's monoplegia and sensory loss. At 2-year follow-up, the patient had no adverse neurological sequelae.
In this case, a delayed postoperative neurological deficit occurred following spinal hyperkyphosis correction. The authors discuss the possible etiological mechanisms behind this complication and suggest strategies for its management.

Abstract
STUDY DESIGN Prospective clinical series. OBJECTIVE To determine the incidence, volume, and extent of postoperative epidural hematoma resulting in thecal sac compression, and to identify risk factors correlated with measured hematoma volumes. SUMMARY OF BACKGROUND DATA Risk factors for postoperative hematoma development have been retrospectively determined in small populations of symptomatic patients. A prospective study of hematoma characteristics and associated risk factors in a consecutive series of patients could significantly enhance our understanding of postoperative hematoma. METHODS Preoperative magnetic resonance imaging and clinical data on 13 pre- and intraoperative risk factors were prospectively collected on 50 consecutive patients undergoing lumbar decompression surgery with or without fusion. Postoperative magnetic resonance imagings were performed within 2 to 5 days of surgery. Thecal sac cross-sectional area was calculated at each disc space. Relative thecal sac compression due to hematoma was calculated at all levels where postoperative cross-sectional area was smaller than preoperative. Hematoma volumes were calculated. Multivariate analysis identified risk factors associated with postoperative hematoma volume. RESULTS After decompression, 58% of patients developed epidural hematoma of sufficient magnitude to compress the thecal sac beyond its preoperative state at one or more levels. None developed new postoperative neurologic deficits. A mean of 1.4 levels were decompressed. Hematoma extended over a mean of 1.9 levels. Maximal thecal sac compression due to hematoma occurred at an adjacent, nondecompressed level in 28% of patients. Multivariate analysis found age greater than 60, multilevel procedures, and preoperative international normalized ratio to be associated with larger hematoma volumes. CONCLUSION Lumbar decompression surgery results in a 58% incidence of asymptomatic compressive postoperative epidural hematoma. Adjacent level compression by hematoma occurs in 28% of patients. Advanced age, multilevel procedures, and international normalized ratio are independently associated with postoperative hematoma volume.
