The placement of epidural catheter may cause complications such as epidural hematoma, epidural abscess and neural damage. Among the above complications, epidural abscess is a rare but serious complication. This report pertains to a diabetic metlitus patient who developed spinal epidural and subdural abscess after continuous epidural catheterization for management of pain caused by reflex sympathetic dystrophy. The patient experienced urinary incontinence, as a neurologic sign, 8 days after epidural catherization. In was considered that the poor prognosis was due to a combination effects of a delayed visit to the hospital for treatment, rapid progression of abscess and uncontrolled blood sugar level. We therefore recommend aseptic technique and proper control of blood sugar level to prevent infection during and after epidural catheterization for diabetic patients. Early diagnosis of epidural abscess following surgical procedure must be required to avoid sequelae.

Hypothermia is relatively a common condition and most cases involve mild hypothermia. But severe hypothermia below $30^{\circ}C$ is medical an emergency condition. We report the case of a 41-year-old man who had been left in a manhole for more than 9 hours on a freezing cold water. He was transported to our emergency room in semicomatose state with a body temperature $26.5^{\circ}C$. The patient was warmed with active rewarming. After initial stabilization, the patient was taken for a brain computed tomography and found to have large fronto-temporo-parietal[FTP] subdural hemorrhage. The patient underwent an emergent decompressive craniectomy and hematoma evacuation. After surgery, he recovered to drowsy mentation and vital signs were stable.

Objective: The detection rate of traumatic subdural hygroma(TSH) has increased after the development of computed tomography and magnetic resonance imaging. The treatment method and the mechanism of development of the TSH have been investigated, but they are still uncertain. This study is performed to evaluate the effectiveness of subduroperitoneal shunt in traumatic subdural hygroma. Methods: Five hundred thirty six patients were diagnosed as TSH from 1996 to 2002, among them, 55 patients were operated with subduroperitoneal shunt. We analyzed shunt effect on the basis of clinical indetails, including the patient's symptoms at the diagnosis, duration from diagnosis to operation, changes of GCS, hygroma types. We classified the TSH into five types (frontal, frontocoronal, coronal, parietal and cerebellar type) according to the location of the thickest portion of TSH. Results: The patients who have symptoms or signs related to frontal lobe compression (irritability, confusion) or increased intracranial pressure (headache, mental change), had symptomatic recovery rate above 80%. However, the patients who have focal neurological sign (hemiparesis, seizure and rigidity), showed recovery rate below 30%. The improvement rate was very low in the case of the slowly progressing TSH for over 6weeks. We experienced complications such as enlarged ventricle, chronic subdural hematoma, subdural empyema and acute SDH. Conclusion: Subduroperitoneal shunt appears to be effective in traumatic subdural hygroma when the patients who have symptoms or signs related to frontal lobe compression or increased ICP and progressing within 5weeks.

Objective : Magnetic resonance imaging (MRI) of chronic subdural hematoma (CSDH) detects various patterns, which can be attributed to many factors. The purpose of this study was to measure the level of interleukin-6 (IL-6), interleukin-8 (IL-8), and highly specific protein [beta-trace protein (${\beta}TP$)] for cerebrospinal fluid (CSF) in CSDHs, and correlate the levels of these markers with the MRI findings. Methods : Thirty one patients, treated surgically for CSDH, were divided on the basis of MRI findings into hyperintense and non-hyperintense groups. The concentrations of IL-6, IL-8, and ${\beta}TP$ in the subdural fluid and serum were measured. The ${\beta}TP$ was considered to indicate an admixture of CSF to the subdural fluid if ${\beta}TP$ in the subdural fluid $({\beta}TP_{SF})/{\beta}TP$ in the serum $({\beta}TP_{SER})>2$. Results : The mean concentrations of IL-6 and IL-8 of the hyperintense group (n=17) of T1-WI MRI were $3975.1{\pm}1040.8pg/mL$ and $6873.2{\pm}6365.4pg/mL$, whereas them of the non-hyperintense group (n=14) were $2173.5{\pm}1042.1pg/mL$ and $2851.2{\pm}6267.5pg/mL$ (p<0.001 and p=0.004). The mean concentrations of ${\beta}TP_{SF}$ and the ratio of ${\beta}TP_{SF}/{\beta}TP_{SER}$ of the hyperintense group (n=13) of T2-WI MRI were $7.3{\pm}2.9mg/L$ and $12.6{\pm}5.4$, whereas them of the non-hyperintense group (n=18) were $4.3{\pm}2.3mg/L$ and $7.5{\pm}3.9$ (p=0.011 and p=0.011). Conclusion : The hyperintense group on T1-WI MRI of CSDHs exhibited higher concentrations of IL-6 and IL-8 than non-hyperintense group. And, the hyperintese group on T2-WI MRI exhibited higher concentrations of ${\beta}TP_{SF}$ and the ratio of ${\beta}TP_{SF}/{\beta}TP_{SER}$ than non-hyperintense group. These findings appear to be associated with rebleeding and CSF admixture in the CSDHs.

A congenital factor VII deficiency is a rare disorder with an estimated incidence in the western contries of one in 500,000. Because factor VII is important in initiation the coagulation cascade, a factor VII deficiency can result in significant bleeding with prolongation of the prothrombin time. We present a case of a factor VII deficiency with a subdural hematoma in an 18-year-old boy whose plasma activity of factor VII was ${\leq}10%$. Previously, he did not have any symptoms, such as hemarthrosis, easy bruising or bleeding after a minor trauma. He was administered fresh frozen plasma and a trephination was performed. His sister also had 51% lower level of factor VII.

Objective: Chronic subdural hematoma (CSDH) is one of the most common types of traumatic intracranial hemorrhage, usually occurring in the older patients, with a good surgical prognosis. Burr hole craniostomy is the most frequently used neurosurgical treatment of CSDH. However, there have been only few studies to assess the role of the number of burr holes in respect to recurrence rates. The aim of this study is to compare the postoperative recurrence rates between one and two burr craniostomy with closed-system drainage for CSDH. Methods: From January 2002 to December 2006, 180 consecutive patients who were treated with burr hole craniostomy with closed-system drainage for the symptomatic CSDH were enrolled. Pre- and post-operative computed tomography (CT) scans and/or magnetic resonance imaging (MRI) were used for radiological evaluation. The number of burr hole was decided by neurosurgeon's preference and was usually made on the maximum width of hematoma. The patients were followed with clinical symptoms or signs and CT scans. All the drainage catheters were maintained below the head level and removed after CT scans showing satisfactory evacuation. All patients were followed-up for at least 1 month after discharge. Results: Out of 180 patients, 51 patients were treated with one burr hole, whereas 129 were treated with two burr holes. The overall postoperative recurrence rate was 5.6% (n = 10/180) in our study. One of 51 patients (2.0%) operated on with one burr hole recurred, whereas 9 of 129 patients (7.0%) evacuated by two burr holes recurred. Although the number of burr hole in this study is not statistically associated with postoperative recurrence rate (p> 0.05), CSDH treated with two burr holes showed somewhat higher recurrence rates. Conclusion: In agreement with previous studies, burr hole craniostomy with closed drainage achieved a good surgical prognosis as a treatment of CSDH in this study. Results of our study indicate that burr hole craniostomy with one burr hole would be sufficient to evacuate CSDH with lower recurrence rate.

Objective : To analyze the clinical data and surgical results from symptomatic chronic subdural hematoma (CSDH) patients who underwent burr-hole drainage (BHD) at the maximal thickness area and twist-drill craniostomy (TDC) at the precoronal point. Methods : We analyzed data from 65 symptomatic CSDH patients who underwent TDC at the pre-coronal point or BHD at the maximal thickness area. For TDC, we defined the pre-coronal point to be 1 cm anterior to the coronal suture at the level of the superior temporal line. TDC was performed in patients with CSDH that extended beyond the coronal suture, as confirmed by preoperative CT scans. Medical records, radiological findings, and clinical performance were reviewed and analyzed. Results : Of the 65 CSDH patients, 13/17 (76.4%) with BHD and 42/48 (87.5%) with TDC showed improved clinical performance and radiological findings after surgery. Catheter failure was seen in 1/48 (2.4%) cases of TDC. Five patients (29.4%) in the BHD group and four patients (8.33%) in the TDC group underwent reoperations due to remaining hematomas, and they improved with a second operation, BHD or TDC. Conclusion : Both BHD at the maximal thickness area and TDC at the pre-coronal point are safe and effective drainage methods for symptomatic CSDHs with reasonable indications.

The purpose of this study was to compare Tc-99m-HMPAO SPECT with MRI after acute and subacute closed-head injury. There were thirty two focal lesions in all cases of these. Fifteen lesions(47%) were seen on both MRI and SPECT. Fourteen lesions(44%) were seen only on MRI. Three lesions(9%) were seen only on SPECT. Of the 14 lesions seen only on MRI, one was epidural hematoma, two were subdural hematoma, three were subdural hygroma, one was intracerebral hematoma, four were contusion, and three were diffuse axonal injuries. SPECT detected 52% of the focal lesions found on MRI. For the detection of lesions, MRI was superior to SPECT in fourteen cases, while SPECT was superior to MRI in three cases. In conclusion, there was a tendency that detection rate of the traumatic lesions was higher on MRI, but the SPECT could delineate more wide extent of lesion.

The intracranial hemorrhage in regions remote from the site of initial operations is unusual but may present as fatal surgical complication. We report a rare case of multiple, sequential, remote intracranial hematomas after cranioplasty in a patient who did not have any prior risk factors. A 51-years-old man was transferred to the hospital after a head trauma. The brain computed tomography (CT) revealed acute subdural hemorrhage on the right hemisphere with prominent midline shifting. After performing decompressive craniectomy and hematoma removal, the patient recovered without any complications. However, the patient showed neurological deterioration immediately after cranioplasty, which was done three months after the first surgery. There was extensive hemorrhage in the posterior fossa remote from the site of the initial operation site. The brain CT taken soon after removing this hematoma evacuation displayed large epidural hematoma on the left hemisphere. This case represents posterior fossa hemorrhage after supratentorial procedure and sequential delayed hematoma on the contralateral supratentorial region thus seems very rare surgical complications. Despite several possible pathogenetic mechanisms for such remote hematomas, there are usually no clear cut relationships with each case as in our patient. However, for the successful outcome, prompt evaluation and intensive management seem mandatory.
