Objective : The purpose of the present study was to determine the incidence of dural tears and predictable factors suggesting dural tears in patients who had lumbar burst fractures with vertical laminar fractures. Methods : A retrospective review was done on thirty-one patients who underwent operative treatment for lumbar burst fractures with vertical laminar fractures between January 2003 and December 2008. All patients were divided into two groups according to existence of dural tears, which were surgically confirmed; 21 patients with dural tears and 10 patients without dural tears. Clinical and radiographic findings were analyzed for their association with dural tears. Results : Among a total of 31 patients, dural tears were detected in 21 (67%) patients. A preoperative neurological deficits and mean separation distances of the edges in laminar fractures were found to be the reliable factors of dural tears (p=0.001 and 0.002, respectively). Decreased ratio of the central canal diameter and interpedicular distance were also the reliable factors suggesting dural tears (p=0.006 and 0.015, respectively). However, dural tears showed no significant association with age, sex, level of injury, absence of a posterior fat pad signal, the angle of retropulsed segment, or site of laminar fracture. Conclusion : Our study of lumbar burst fracture combined laminar fracture revealed that dural tears should be ruled out in cases of a preoperative neurological deficits, wide separation of the laminar fracture, severe canal encroachment, and wider interpedicular distance.

Traumatic carotid-cavernous fistula is a rare complication of moderate to severe head injury. For the treatment of carotid-cavernous fistula, detachable balloon occlusion is the best method of choice. A 26 year old male patient was hurt with a left periorbital penetrating injury 20 years ago, and then left side exophthalmos, bruit and right hemiparesis developed 10 years later. We experienced the very rare case of direct carotidcavernous fistula with cavernous dural arteriovenous fistula. Brain MRIs and cerebral angiograms revealed that direct carotid-cavernous fistula was accompanied by cavernous dural arteriovenous fistula due to longstanding venous hypertension and development of collateral circulation. Detachable balloon occlusion and surgical internal carotid artery ligation were not enough to occlude fistular flow, so cavernous dural arteriovenous fistula embolization was necessary. The authors present a case of long-standing traumatic carotid-cavernous fistula with cavernous dural arteriovenous fistula, with review of the literature.

Authors report a rare case of acute intracranial subdural and intraventricular hemorrhage that were caused by intracranial hypotension resulted from cerebrospinal fluid leakage through an unidentified dural tear site during spinal surgery. The initial brain computed tomography image showed acute hemorrhages combined with preexisting asymptomatic chronic subdural hemorrhage. One burr hole was made over the right parietal skull to drain intracranial hemorrhages and subsequent drainage of cerebrospinal fluid induced by closure of the durotomy site. Among various methods to treat cerebrospinal fluid leakage through unidentified dural injury site, primary repair and spinal subarachnoid drainage are well known treatment options. The brain imaging study to diagnose intracranial hemorrhage should be taken before selecting the treatment method, especially for spinal subarachnoid drainage. Similar mechanism to its spinal counterpart, cranial cerebrospinal fluid drainage has not been mentioned in previous article and could be another treatment option to seal off an unidentified dural tear in particular case of drainage of intracranial hemorrhage is needed.

A 38-year-old Korean man without any other history was diagnosed with myelopathy due to a spinal dural arteriovenous fistula. Following embolization and high-dose steroid therapy, the patient was treated with complex Korean medical therapies including acupuncture, pharmacopuncture, electro-acupuncture, Chuna manual therapy, herbal medicine, and cupping therapy in addition to conventional treatment. To assess the patient's improvement, international standard for neurological classification of spinal cord injury, Korean version of modified Barthel index, functional independence measure, spinal cord independence measure III, walking index for spinal cord injury II, modified Ashworth scale were used. After treatment, the muscle strength and sensory function of the lower extremities were improved, and the spasticity was reduced, resulting in a rapid improvement in performance of daily activities. These results suggest that complex Korean medical therapies may be effective for myelopathy, and further clinical studies are needed to clarify their effects.

Purpose: Traumatic cervical SCI is frequently accompanied by dural tear and the resulting cerebrospinal fluid (CSF) leak after surgery can be troublesome and delay rehabilitation with increasing morbidity. This study evaluated the incidence of intraoperative CSF leaks in patients with traumatic cervical spinal cord injury (SCI) who underwent anterior cervical surgery and described the reliable management of CSF leaks during the perioperative period. Methods: A retrospective study of medical records and radiological images was done on patients with CSF leaks after cervical spine trauma. Results: Seven patients(13.2%) were identified with CSF leaks during the intraoperative period. All patients were severely injured and showed structural abnormalities on the initial magnetic resonance image (MRI) of the cervical spine. Intraoperatively, no primary repair of dural tear was attempted because of a wide, rough defect size. Therefore, fibrin glue was applied to the operated site in all cases. Although a wound drainage was inserted, it was stopped within the first 24 hours after the operation. No lumbar drainage was performed. Postoperatively, the patients should kept their heads in an elevated position and early ambulation and rehabilitation were encouraged. None of the patients developed complications related to CSF leaks during admission. Conclusion: The incidence of CSF leaks after surgery for cervical spinal trauma is relatively higher than that of cervical spinal stenosis. Therefore, one should expect the possibility of a dural tear and have a simple and effective management protocol for CSF leaks in trauma cases established.

We report a rare case of remote cerebellar hemorrhage after intradural disc surgery at the L1-2 level. Two days after the spine surgery, patient complained unexpected headache, dizziness, nausea and vomiting. From the urgently conducted brain CT, it was reported that the patient had cerebellar hemorrhage. Occipital craniotomy and hematoma evacuation was performed, and hemorrhagic lesion on the right cerebellum was effectively removed. After occipital craniotomy, the patient showed signs of improvement on headache, dizziness, nausea and vomiting. He was able to leave the hospital after two weeks of initial operation without any neurological deficit. Remote cerebellar hemorrhage following spinal surgery is extremely rare, but may occur from dural damage of spinal surgery, accompanied with cerebrospinal fluid leakage. Early diagnosis is particularly important for the optimal treatment of remote cerebellar hemorrhage.

Purpose: This study was conducted to investigate the usefulness of a polyester urethane dural substitute (Neuro-Patch^®, B. Braun, Boulogne, France) as an anti-adhesion agent in subsequent cranioplasty by analyzing the use of Neuro-Patch^® during decompressive craniectomy in traumatic brain injury patients. Methods: We retrospectively analyzed patients with traumatic brain injury who underwent decompressive craniectomy followed by cranioplasty from January 2015 to December 2018. Patients were analyzed according to whether they received treatment with Neuro-Patch^® or not (Neuro-Patch^® group, n=71; control group, n=55). Patients' baseline characteristics were analyzed to identify factors that could affect cranioplasty results, including age, sex, hypertension, diabetes mellitus, use of antiplatelet agents or anticoagulant medication, the interval between craniectomy and cranioplasty, and the type of bone used in cranioplasty. The cranioplasty results were analyzed according to the following factors: operation time, blood loss, postoperative hospitalization period, surgical site infection, and revision surgery due to extra-axial hematoma. Results: No significant difference was found between the two groups regarding patients' baseline characteristics. For the cranioplasty procedures, the operation time (155 vs. 190 minutes, p=0.003), intraoperative blood loss (350 vs. 450 mL, p=0.012), and number of surgical site infections (4 vs. 11 cases, p=0.024) were significantly lower in the Neuro-Patch^® group than in the control group. Conclusions: The use of Neuro-Patch^® was associated with a shorter operation time, less blood loss, and a lower number of surgical site infections in subsequent cranioplasties. These results may provide a rationale for prospective studies investigating the efficacy of Neuro-Patch^®.

Dural injury during spinal surgery can subsequently give rise to a remote cerebellar hemorrhage (RCH). Although the incidence of such injury is low, the resulting hemorrhage can be life threatening. The mechanism underlying the formation of the hemorrhage is not known, but it is mostly thought to develop after venous infarction. Cerebellar mutism (CM) is a frequent complication of posterior fossa operations in children, but it is rarely seen in adults. The development of CM after an RCH has not been described. We describe the case of a 65-year old female who lost cerebrospinal fluid after inadvertent opening of the dura during surgery. Computerized tomography performed when the patient became unable to speak revealed a bilateral cerebellar hemorrhage.
