Comparison of treatment results between microvascular decompression and gamma knife radiosurgery in primary trigeminal neuralgia.

This study aims to analyze and evaluate the comparative clinical outcomes associated with microvascular decompression (MVD) and gamma knife radiosurgery (GKRS), focusing on pain relief, pain recurrence, and complications encountered in the treatment of trigeminal neuralgia (TN). Among 155 surgical procedures performed for TN (90 GKRS, and 65 MVD) between March 1997 and December 2020, the exclusion criteria encompassed prior surgical interventions, the presence of other pathological conditions such as tumors, vascular diseases, and multiple sclerosis, as well as patients who were lost to follow-up. Ultimately, 101 patients received their initial treatment for primary TN (47 GKRS, and 54 MVD) and were followed up for more than 1 year. The MVD procedures utilized the suboccipital retrosigmoid sinus approach, whereas GKRS was conducted with MR imaging guidance, employing a single 4mm isocenter, with median GKRS doses of 80 Gy. We retrospectively analyzed patient characteristics, including sites of divisions, distributions of pain, and clinical outcomes. The assessment of outcomes was performed utilizing the Barrow Neurological Institute Pain Intensity Score and the Visual Analog Scale (VAS), with evaluations taking place preoperatively and after 1, 3, 6 and 12 months. Postoperative VAS scores for patients undergoing either MVD or GKRS demonstrated a significant improvement when compared with their preoperative counterparts. The reduction in postoperative VAS scores within the MVD group was significantly more substantial than that observed in patients who underwent GKRS at the initial postoperative evaluations (P = .037). The maintenance of pain relief after MVD proved significantly superior to that following GKRS (P < .01). Both MVD and GKRS present as safe and efficacious therapeutic options for individuals diagnosed with primary TN, though MVD displayed superior initial outcomes in terms of pain relief and its maintenance. However, for older patients or those with medical contraindications to invasive procedures, GKRS emerges as a viable and less invasive alternative for initial treatment in cases of primary TN.

Surgical outcome of minimal invasive oblique lateral interbody fusion with percutaneous pedicle screw fixation in the treatment of adult degenerative scoliosis.

Oblique lateral interbody fusion is performed for lumbar spinal restoration and stabilization, without extensive paraspinal muscle damage or massive bleeding. This study aimed to confirm the radiological and clinical outcomes of minimally invasive oblique lateral interbody fusion (OLIF) with percutaneous pedicle screw fixation (PPSF) as treatment for adult degenerative lumbar scoliosis. Medical records of 40 patients with degenerative lumbar spinal deformities who underwent selective OLIF and PPSF at our hospital between April 2018 and February 2021 were retrospectively reviewed. The study population comprised 7 male and 33 female patients aged 55-79 years. Standing radiography was performed, and the coronal cobb angle, distance between the C7 plumb line and central sacral vertical line, sagittal vertical axis, pelvic tilt, lumbar lordosis (LL), pelvic incidence (PI), and difference between PI and LL (PI-LL) were measured. Coronal scoliosis was defined as a lumbar coronal plane curve of > 15°. All patients achieved statistically significant improvements in coronal and sagittal alignment. The coronal cobb angle was corrected from 18.82° to 11.52°, and the central sacral vertical line was reduced from 18.30 mm to 15.47 mm. The sagittal vertical axis was significantly reduced from 45.95 mm to 32.72 mm. In contrast, the pelvic tilt and LL were minimally changed. For subgroup analyses, patients were divided into the convex and concave groups according to the direction of coronal curve correction. Vertebral body rotation was superior in the convex group than in the concave group. Furthermore, we checked for asymmetric facet degeneration at the upper instrumented vertebra (UIV) level at 1 year postoperatively. Of the 22 patients who underwent more than 3 level fusion surgery, 8 patients were confirmed the postoperative asymmetric facet degeneration in above UIV. Minor complications occurred in 16 patients, who recovered without any problems. Revision surgery was not performed in all cases. Minimally invasive OLIF with PPSF has a lower risk of complications and favorable surgical outcomes in patients with adult degenerative lumbar scoliosis. Access from the convex side is advantageous for the correction of the rotated vertebra. Extending the UIV level to the neutral vertebra can reduce the occurrence of postoperative asymmetric facet degeneration.

Personal experience with microvascular decompression and partial sensory rhizotomy for trigeminal neuralgia.

BACKGRUOUND: Trigeminal neuralgia (TN) is a severe, paroxysmal pain in the distribution of the fifth cranial nerve. Microvascular decompression (MVD) is the most widely used surgical treatment for TN. We undertook this study to analyze the effects of and complications of MVD and to refine the surgical procedure for treating TN. METHODS: A total of 88 patients underwent for TN underwent surgery at our hospital. Among them, 77 patients underwent MVD alone, and 11 underwent partial sensory rhizotomy (PSR) with or without MVD. The medical records of these patients were retrospectively analyzed for patient characteristics, clinical results, offending vessels, and complications if any. RESULTS: The mean follow-up duration was 43.2 months (range, 3-216 months). The most common site of pain was V2+V3 territory (n=27), followed by V2 (n=25) and V3 (n=23). The most common offending vessels were the superior cerebellar artery and anterior inferior cerebellar artery in that order. The overall rate of postoperative complications was 46.1%; however, most complications were transient. There were two cases of permanent partial hearing disturbance. In the MVD alone group, the cure rate was 67.5%, and the improvement rate was 26.0%. Among 11 patients who underwent PSR with or without MVD, the cure rate was 50.0%, and the improvement rate was 30.0%. CONCLUSION: The clinical results of MVD were satisfactory. Although the outcomes of PSR were not as favorable as those of pure MVD in this study, PSR can be considered in cases where there is no significant vascular compressive lesion or uncertainty of the causative vessel at the surgery.

Endovascular treatment of the vertebral artery origin stenosis by using the closed-cell, self-expandable Carotid Wallstent.

BACKGROUND: Endovascular treatment has been considered a good alternative to surgery for symptomatic vertebral artery origin stenosis (VAOS) due to the high risk of morbidity associated with surgery. The purpose of this study was to evaluate the feasibility and efficacy of insertion of the closed-cell, self-expandable Carotid Wallstent for the treatment of VAOS. METHODS: The records of 72 patients with VAOS refractory to adequate medication who were treated by endovascular treatment with the Carotid Wallstent from December 2006 to November 2018 were retrospectively evaluated. RESULTS: Of the 72 patients, 43 presented with transient ischemic attacks. Forty-seven patients (65.3%) manifested other brachiocephalic stenoses; of these, 40 patients had occlusion, hypoplasia, or stenosis of the contralateral vertebral artery. Overall technical success (defined as 20% or less residual stenosis) was 100%. Procedure-related complications (n = 8, 11.1%) included sudden asystole (n = 1), acute in-stent thrombosis (n = 3), minor stroke (n = 3), and stent shortening (n = 1). All complications were resolved without permanent neurological deficit. Angiographic follow-up (mean, 13.0 months) was achieved in 49 patients and revealed in-stent restenosis in 1 patient (2.0%) and stent malposition by shortening in 2 patients (4.1%). Follow-up records were available in 57 patients (mean 15.6 months). Three of the 57 patients (n = 3, 5.3%) had recurrent symptoms of vertebrobasilar ischemia and none was retreated. CONCLUSIONS: Endovascular treatment of symptomatic VAOS using the closed-cell, self-expandable Carotid Wallstent is technically feasible and effective in alleviating patient symptoms and for improving vertebrobasilar blood flow.

The Effect of Pain Reduction during Headframe Fixation for Stereotactic Radiosurgery by the Preceded Local Anesthesia under the Needle Cap Guidance.

BACKGROUND: Gamma knife radiosurgery (GKRS) has become a major alternative in the neurosurgical field. However, many patients complained of considerable discomfort during the fixation of rigid headframe. This study investigated whether our modified procedure could reduce fixation-related pain. METHODS: Sixty-six patients who underwent GKRS were enrolled in this study. Thirty-one patients (Group A) underwent the conventional subcutaneous infiltration technique, and 35 patients (Group B) did the modified procedure. In group A, the headframe was held in position by an assistant, and local anesthetics were injected subcutaneously using a 23-gauge spinal needle at pinning sites. Subsequently, pins were applied according to measurements based on spinal needle depth. In group B, with the frame held in position by an assistant, pin sites were marked with a surgical pen under the guidance of needle cap placed on the pin holes. The head frame was then removed, and local anesthetics were injected subcutaneously and periosteally at each marked pin site using a 26-gauge needle. The headframe was then repositioned 5 minutes after local infiltration, and pins were applied according to measurements based on spinal needle depth. To evaluate pain severity during procedures, visual analogue scale (VAS) scores were recorded during local infiltration and frame placement with pins. The pain scores of the two groups were analyzed statistically. RESULTS: Group B had a significantly lower VAS score during frame placement than group A (7.26 vs. 3.61; p<0.001), and mean VAS score at local infiltration was also significantly lower in group B (4.74 vs. 3.74; p=0.008). CONCLUSION: Patients in group B experienced significantly less pain than those in group A during pin placement. Pre-fixation time advanced local anesthesia might reduce pain during stereotactic procedures, and the use of a 26-gauge needle appeared in less pain during local infiltration.

Obtaining Informed Consent Using Patient Specific 3D Printing Cerebral Aneurysm Model.

OBJECTIVE: Recently, three-dimensional (3D) printed models of the intracranial vascular have served as useful tools in simulation and training for cerebral aneurysm clipping surgery. Precise and realistic 3D printed aneurysm models may improve patients' understanding of the 3D cerebral aneurysm structure. Therefore, we created patient-specific 3D printed aneurysm models as an educational and clinical tool for patients undergoing aneurysm clipping surgery. Herein, we describe how these 3D models can be created and the effects of applying them for patient education purpose. METHODS: Twenty patients with unruptured intracranial aneurysm were randomly divided into two groups. We explained and received informed consent from patients in whom 3D printed models-(group I) or computed tomography angiography-(group II) was used to explain aneurysm clipping surgery. The 3D printed intracranial aneurysm models were created based on time-offlight magnetic resonance angiography using a 3D printer with acrylonitrile-butadiene-styrene resin as the model material. After describing the model to the patients, they completed a questionnaire about their understanding and satisfaction with aneurysm clipping surgery. RESULTS: The 3D printed models were successfully made, and they precisely replicated the actual intracranial aneurysm structure of the corresponding patients. The use of the 3D model was associated with a higher understanding and satisfaction of preoperative patient education and consultation. On a 5-point Likert scale, the average level of understanding was scored as 4.7 (range, 3.0-5.0) in group I. In group II, the average response was 2.5 (range, 2.0-3.0). CONCLUSION: The 3D printed models were accurate and useful for understanding the intracranial aneurysm structure. In this study, 3D printed intracranial aneurysm models were proven to be helpful in preoperative patient consultation.

Supratentorial Pilocytic Astrocytoma Mimicking Convexity Meningioma with Early Anaplastic Transformation: A Case Report.

Meningiomas and pilocytic astrocytomas are benign intracranial tumors. Pilocytic astrocytomas arises frequently at the posterior fossa in childhood. Meningiomas have several image findings, such as a dural tail sign, bony erosion, and sunburst appearance on angiography. However, pilocytic astrocytomas with these findings have been rarely reported. In this report, we describe a mass with typical image findings of a meningioma, but diagnosed as a supratentorial pilocytic astrocytoma with early anaplastic transformation.

Subfrontal Schwannoma Extended Broadly to Nasal Cavity Treated by Gamma Knife Radiosurgery Following Surgical Excision: A Case Report.

Subfrontal schwannomas are rarely reported. They are usually found only in the subfrontal area, but some extend to the nasal cavity. In these cases, prevention of postoperative cerebrospinal fluid (CSF) leakage through thinned or eroded anterior skull base is important. A 51-year-old female with anosmia and mild nausea was diagnosed as subfrontal extraaxial mass with nasal cavity extension. This mass was initially thought to be an olfactory groove meningioma. We performed a bifrontal craniotomy for surgical excision. We did not totally remove the tumor, as we wanted to prevent a skull base defect. The histopathological diagnosis was a schwannoma. There was no postoperative complication such as CSF leakage. The residual tumor was treated with gamma knife radiosurgery. The nasal cavity mass has not grown as of five years after radiosurgery.

The Efficacy of Single Barrel Superficial Temporal Artery-middle Cerebral Artery Bypass in Treatment of Adult Patients with Ischemic-type Moyamoya Disease.

OBJECTIVE: So far, there is no study answering the question of which type of surgical technique is practically the most useful in the treatment of adult patients with ischemic type moyamoya disease (MMD). We evaluated the efficacy of single barrel superficial temporal artery (STA)-middle cerebral artery (MCA) bypass in the treatment of adult patients with ischemic type MMD by retrospectively collecting clinical and radiological data. MATERIALS AND METHODS: A retrospective review identified 31 adult patients who underwent 43 single barrel STA-MCA bypass procedures performed for treatment of ischemic-type MMD between 2006 and 2014. The male to female ratio was 17:14 and the mean age was 41 years (range, 21-65 years). Peri-operative complications, angiographic and clinical outcomes were analyzed retrospectively. RESULTS: The permanent neurological morbidity and mortality rates were 2.3% and 0%, respectively. During the observation period of a mean of 35 months (range, 12-73 months), 29 patients (93.5%) had no further cerebrovascular events and transient ischemic attack occurred in two patients (6.5%), resulting in an annual stroke risk of 2.2%. Follow-up computed tomography perfusion (CTP) (mean, 18.4 months after surgery) documented improved cerebral hemodynamics in the revascularized hemispheres (p < 0.001). Post-operative patency was clearly verified in 38 bypasses (88.4%) of 43 bypasses on follow-up imaging (mean, 16.5 months). CONCLUSION: Our results suggest that single barrel STA-MCA bypass with wide dural opening is safe and durable method of cerebral revascularization in adult patients with ischemic type MMD and can be considered as a potential treatment option for adult patients with ischemic type MMD.

Emergency placement of stent-graft for symptomatic acute carotid artery occlusion after endarterectomy.

A patient underwent a left-sided carotid endarterectomy (CEA) for an asymptomatic 80% carotid artery (CA) stenosis. There were no signs of intolerance during the carotid cross-clamping and an initially uneventful awakening was observed. However, in the third postoperative hour he experienced left amaurosis and dysarthria. An urgent MRI showed an occluded internal CA on the operated site without evidence of acute infarction. To recanalize the occluded internal CA and minimize leakage from the arteriotomy site, a self-expandable stent-graft was placed, covering the dissection and the distal atherosclerotic lesions. Complete recanalization of the left internal CA was achieved and the patient showed a dramatic improvement of his preoperative deficits. To our knowledge, this is the first case of stent-graft implantation for a symptomatic acute CA occlusion following CEA. Stent-graft placement should be considered as an alternative method of treatment for acute CA occlusion or dissection following CEA.

Paradoxical exacerbation of symptoms with obstruction of the venous outflow after gamma knife radiosurgery for treatment of a dural arteriovenous fistula of the cavernous sinus.

A 59-year-old female presented with progressive right proptosis, chemosis and ocular pain. An imaging work-up including conventional catheter angiography showed a right-sided dural arteriovenous fistula of the cavernous sinus, which drained into the right superior petrosal sinus, right superior ophthalmic vein, and right inferior ophthalmic vein, and cortical venous reflux was seen via the right petrosal vein in the right posterior fossa. After failure of transvenous embolization, the patient underwent Gamma Knife radiosurgery (GKRS). At one month after GKRS, she developed increasing ocular pain and occipital headache. Repeat angiography showed partial obliteration of the fistula and loss of drainage via the superior and inferior ophthalmic veins with severe congestion, resulting in slow flow around the right cerebellar hemisphere. Prompt transarterial embolization relieved the patient's ocular symptoms and headache. We report on a case of paradoxical exacerbation of symptoms resulting from obstruction of the venous outflow after GKRS for treatment of a dural arteriovenous fistula of the cavernous sinus.

Endovascular treatment of acute intracranial vertebral artery dissection: long-term follow-up results of internal trapping and reconstructive treatment using coils and stents.

BACKGROUND: Endovascular internal trapping is an effective procedure for the treatment of acute vertebral artery dissection (VAD). However, the outcomes of reconstructive treatment have not been well established. The aim of our study is to evaluate the long-term clinical and angiographic results of endovascular internal trapping or reconstructive treatment of acute VAD. METHODS: Between 2005 and 2013, 26 patients with acute VAD were managed with internal coil trapping (n=10), stent-assisted coiling (n=14), stent only (n=1), and proximal occlusion (n=1). Stent-assisted coiling included the modified stent-assisted semi-jailing technique (n=10), balloon-in-stent technique (n=2), and coiling followed by balloon mounted stent (n=2). Digital subtraction angiography (DSA) was performed in all patients except for three who died during the acute stage. RESULTS: Of 26 patients with VAD, 14 and 12 presented with hemorrhagic and non-hemorrhagic types, respectively. The dominancy of the relevant artery was defined as dominant (n=9), even (n=12), and non-dominant (n=5). Reconstructive treatment was performed in six patients with ruptured VADs which failed balloon test occlusion and nine with non-hemorrhagic VADs. Clinical outcomes were favorable in 22 (84.6%), severe disability occurred in one, and there were three deaths (11.5%). All patients except the three who died had angiographic follow-up at 6-32 months (mean 10.4 months). The angiographic results of nine cases of internal trapping and one of proximal occlusion all showed a stable occlusion state. Among the 15 cases of reconstructive treatment, follow-up DSAs were available for the 13 surviving patients, 10 of which demonstrated stable occlusion of aneurysmal dilation and patent parent artery. CONCLUSIONS: This study suggests that internal trapping is a stable and effective treatment for acute VAD. Reconstructive treatment using stent and coils could also be a feasible alternative modality for hemorrhagic type VAD. However, serial DSA follow-up is essential.

Regrowth of Cervical Intradural Lipoma without Spinal Dysraphism.

A 49 years old male patient who suffered from deterioration of posterior neck pain, left hand numbness, left lower limb pain and gait disturbance for 3 years visited our outpatient department. He had been diagnosed as non-dysraphic cervical intradural lipoma and operated in August 1990. On the radiologic images, we found the regrowth of non-dysraphic cervical intradural lipoma from C2 to C7 level, which surrounds and compresses the cervical spinal cord. Previous subtotal laminectomy from C2 to C7 and severe cervical lordosis were also found. Appropriate debulking of lipoma mass without duroplasty was successfully done with intraoperative neurophysiological monitoring (IONM). We are following up the patient for 24 months via outpatient department, his neurologic symptoms such as hand numbness, gait disturbance, left lower limb pain and posterior neck pain have improved. We describe a rare case of regrowth of non-dysraphic cervical intradural lipoma.

Sphenoid ridge meningioma presenting as acute cerebral infarction.

A previously healthy 52-year-old man presented to the emergency room with acute onset left hemiparesis and dysarthria. Brain computed tomography and magnetic resonance examinations revealed acute cerebral infarction in the right middle cerebral artery territory and a sphenoid ridge meningioma encasing the right carotid artery terminus. Cerebral angiography demonstrated complete occlusion of the right proximal M1 portion. A computed tomography perfusion study showed a wide area of perfusion-diffusion mismatch. Over the ensuing 48 hours, left sided weakness deteriorated despite medical treatment. Emergency extracranial-intracranial bypass was performed using a double-barrel technique, leaving the tumor as it was, and subsequently his neurological function was improved dramatically. We present a rare case of sphenoid ridge meningioma causing acute cerebral infarction as a result of middle cerebral artery compression.

Allicin inhibits cell growth and induces apoptosis in U87MG human glioblastoma cells through an ERK-dependent pathway.

Allicin, the main flavor compound in garlic, has anti-carcinogenic activities in a range of cancer cells, however, the underlying molecular mechanisms are not completely understood. This study examined the effect of allicin on the cell viability of U87MG human glioma cells along with its molecular mechanisms of induction of cell death. Apoptosis was determined by TUNEL and Hoechst 33258 staining as well as by western blot analysis. Allicin inhibited the cell viability of U87MG human glioma cells in a dose- and time-dependent manner. Allicin-induced inhibition of cell viability was due to apoptosis of cells. The mechanisms of apoptosis were found to involve the mitochondrial pathway of Bcl-2/Bax, the MAPK/ERK signaling pathway and antioxidant enzyme systems. These results suggest that allicin can serve as a novel chemotherapeutic candidate for the treatment of glioblastoma multiforme.

Intramedullary spinal cord metastasis of choriocarcinoma.

The authors describe a case of choriocarcinoma that metastasized to the cerebral cortex, vertebral body, and intramedullary spinal cord. A 21-year-old woman presented with sudden headache, vomiting and a visual field defect. Brain computed tomography and magnetic resonance examinations revealed an intracranial hemorrhage in the left temporo-parietal lobe and two enhancing nodules in the left temporal and right frontal lobe. After several days, the size of the hemorrhage increased, and a new hemorrhage was identified in the right frontal lobe. The hematoma and enhancing mass in the left temporo-parietal lobe were surgically removed. Choriocarcinoma was diagnosed after histological examination. At 6 days after the operation, her consciousness had worsened and she was in a state of stupor. The size of the hematoma in the right frontal lobe was enlarged. We performed an emergency operation to remove the hematoma and enhancing mass. Her mental status recovered slowly. Two months thereafter, she complained of paraplegia with sensory loss below the nipples. Whole spine magnetic resonance imaging revealed a well-enhancing mass in the thoracic intramedullary spinal cord and L2 vertebral body. Despite chemotherapy and radiotherapy, the patient died 13 months after the diagnosis.

Massive intracerebral hemorrhage caused by a cavernous malformation.

We present a rare case of massive intracerebral hemorrhage resulting from a small, superficially-located supratentorial cavernous malformation, or cavernoma. These lesions rarely lead to massive, life-threatening intracerebral hemorrhages. A 17-year-old female presented with a 3-week history of declining mental status. Brain computed tomography and magnetic resonance imaging revealed a sizable intracranial hemorrhage, within the right occipital region, associated with a small nodule at the hematoma's posterior margin. An emergency operation removed the entire hematoma and nodule. Histological examination of the nodule was compatible with a diagnosis of cavernous malformation. The patient's post-operative course was uneventful.

Non-dura based intaspinal clear cell meningioma.

A 34-year-old female patient was presented with leg and hip pain for 6 months as well as voiding difficulty for 1 year. Magnetic resonance imaging revealed a well-demarcated mass lesion at L2-3. The mass was hypo-intense on T1- and T2-weighted images with homogeneous gadolinium enhancement. Surgery was performed with the presumptive diagnosis of intradural extramedullary meningioma. Complete tumor removal was possible due to lack of dural adhesion of the tumor. Histologic diagnosis was clear cell meningioma, a rare and newly included World Health Organization classification of meningioma usually affecting younger patients. During postoperative 2 years, the patient has shown no evidence of recurrence. We report a rare case of cauda equina clear cell meningioma without any dural attachment.

The proteasome inhibitor MG-132 induces AIF nuclear translocation through down-regulation of ERK and Akt/mTOR pathway.

Anticancer activity of proteasome inhibitors has been demonstrated in various cancer cell types. However, mechanisms by which they exert anticancer action were not fully understood. The present study was undertaken to examine the effect of the proteasome inhibitor MG-132 and the underlying mechanism in glioma cells. MG-132 caused alterations in mitochondrial membrane potential and apoptosis-inducing factor (AIF) nuclear translocation. MG-132 induced reduction in ERK and Akt activation. The transient transfection of constitutively active forms of MEK, an upstream of ERK, and Akt blocked the MG-132-induced cell death. Similarly to down-regulation of Akt, expression levels of mTOR were inhibited by MG-132. Addition of rapamycin, an inhibitor of mTOR, caused stimulation of the MG-132-induced cell death. There were no significant changes in levels of XIAP, survivin, and Bax. Overexpression of constitutively active forms of MEK and Akt blocked the MG-132-induced AIF nuclear translocation. These findings indicate that MG-132 induces AIF nuclear translocation through down-regulation of ERK and Akt/mTOR pathways. These data suggest that proteasome inhibitors may serve as potential therapeutic agents for malignant human gliomas.

Spinal epidural hematoma after pain control procedure.

Spinal epidural hematoma is a rare complication associated with pain control procedures such as facet block, acupuncture, epidural injection, etc. Although it is an uncommon cause of acute myelopathy, and it may require surgical evacuation. We report four patients with epidural hematoma developed after pain control procedures. Two procedures were facet joint blocks and the others were epidural blocks. Pain was the predominant initial symptom in these patients while two patients presented with post-procedural neurological deficits. Surgical evacuation of the hematoma was performed in two patients while in remaining two patients, surgery was initially recommended but not performed since symptoms were progressively improved. Three patients showed near complete recovery except for one patient who recovered with residual deficits. Although, spinal epidural hematoma is a rare condition, it can lead to serious complications like spinal cord compression. Therefore, it is important to be cautious while performing spinal pain control procedure to avoid such complications. Surgical treatment is an effective option to resolve the spinal epidural hematoma.
