Purpose: Spinal epidural hematoma (EDH) is a rare condition requiring an urgent diagnosis and management. We describe here the clinical features, magnetic resonance image (MRI) findings, and outcomes of surgery in six patients with spinal EDH. Methods: We retrospectively analyzed six patients who underwent surgery for spinal EDH between April 2004 and May 2010. Preoperative MRI findings within 48 hours of symptom occurrence were analyzed for cord compression, extent of EDH, and presence of vascular abnormalities. Pre- and postoperative neurological status was also assessed comparatively. Results: Our six patients consisted of three men and three women, with a mean age of 70 years (range: 54-88 years), who presented with the back pain or motor weakness. The mean follow-up period was 34 months (range: 2-72 months). Two patients had cardiovascular disease and were taking warfarin, but the others had no history of medical comorbidity. Those two patients taking warfarin had a history of trauma, another one experienced symptoms during a strenuous effort, and the others developed spontaneously. Before surgery, motor power was grade III in three patients, grade 0 in two patients, and normal in one patient. Preoperative MRI showed no vascular abnormalities except for the EDH in any patient. At the last follow-up, all those five patients with motor weakness showed neurological improvement compared to their preoperative status. There were no complications related to surgery. All six patients were able to ambulate with or without an assistive device. Conclusion: Spinal EDH can occur in patients without trauma, bleeding diathesis, or combined vascular pathology. The surgical outcomes of spinal EDH seem to be satisfactory, even in quadriplegic patients.

국제 표준화 기구인 ITU, ISO/IEC JTC1을 비롯해 지역 표준화 기구인 ETSI, 국가 기구인 Committee T1, TTA 등은 표준의 신속한 제정 및 적기의 공급을 위해 각각의 표준화 절차에 기반한 전자적 문서처리(EDH)시스템을 구축하고, 이를 통해 표준화 진행에 관련된 각종 정보를 효율적으로 처리할 수 있는 전자적 환경을 구축하는데 많은 노력을 기울이고 있다. 본 고에서는 유럽의 ETSI, 미국의 Committee T1, 국제 기구인 JTC1, 지역 표준화 협력기구인 GSC, 그리고 지난해 7월 조직 개편을 단행한 한국정보통신기술협회(TTA)를 대상으로 최근 인터넷 관련 각종 정보처리기술을 이용하여, 이를 표준화 절차에 활용하고 있는 전자적 작업방법 및 이와 관련된 지침을 조사분석하였다.

국제 표준화 기구인 ITU, ISO/IEC/JTC1를 비롯해 ETSI, Committee T1, TTA 등 각 지역 표준화 기구들은 급속한 기술개발에 따른 적기의 표준공급 및 전자적 표준화 문서유통을 통한 신속한 표준제정을 위해 EDH(Electronic Document Handling)에 기반을 둔 정보유통시스템을 구축하고 기고서, 표준관련 문서, 표준승인을 위한 전자투표 등 표준화진행에 관련된 각종 정보를 전자적으로 검색하고 처리할 수 있는 환경을 구축하는데 많은 노력을 기울이고 있다. 본 고에서는 ITU--T와 최근 Web 기반 전자문서처리를 구축한 ISO/IEC/JTC1 그리고Committee T1 및 국내 민간표준화 단체인 한국정보통신기술협회를 대상으로 관련 표준화과제 중심의 조직체계와 현재 시행하고 있는 전자적 문서처리 현황을 고찰한다.

We report a case of an acute spontaneous epidural hematoma (EDH) due to skull base metastasis in a 46-year-old male patient with hepatocellular carcinoma (HCC). The patient presented with the acute onset of severe headache followed by unconsciousness, and computed tomography showed a large EDH in the right temporal and parietal lobes with midline shift. Emergency evacuation of the EDH was performed, and the hemorrhage was determined to be secondary to skull base metastasis of HCC.

Cephalohematoma with epidural hematoma[EDH] is a known complication of birth trauma and is usually best managed by observation only. However, this complication may jeopardize a neonatal life because of cranial compromise and hemodynamic instability. It should also be recognized that surgical intervention confers undoubted benefits on patients in some cases. We report a case of massive EDH with cephalohematoma and linear skull fracture, successfully treated with a craniotomy and evacuation of the hematoma.

A 65-year-old man who had lateral cervical disc herniation underwent cervical posterior laminoforaminotomy at C5-6 and C6-7 level right side. During the operation, there was no serious surgical bleeding event. After operation, he complained persistent right shoulder pain and neck pain. Repeated magnetic resonance image (MRI) showed diffuse cervical epidural hematoma (EDH) extending from C5 to T1 level right side and spinal cord compression at C5-6-7 level. He underwent exploration. There was active bleeding at muscular layer. Muscular active bleeding was controlled and intramuscular hematoma was removed. The patient's symptom was reduced after second operation. Symptomatic postoperative spinal EDH requiring reoperation is rare. Meticulous bleeding control is important before wound closure. In addition, if patient presents persistent or aggravated pain after operation, rapid evaluation using MRI and second look operation is needed as soon as possible.
