Objective : Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluatedthe effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH). Methods : Between July 2008 and July 2013, 234 patients were included in this study. The LD group consisted of 126 patients, 108 patients in the non LD group. We investigated outcomes as follow : 1) clinical vasospasm, 2) angioplasty,

Spinal subdural hematoma (SSDH) is an extremely uncommon condition. Causative factors include trauma, anticoagulant drug administration, hemostatic disorders, and vascular disorders such as arteriovenous malformations and lumbar punctures. Of SSDH cases, those that do not have any traumatic event can be considered cases of nontraumatic acute spinal subdural hematoma, which is known to have diverse clinical progress. Treatment typically consists of surgical decompression and cases in which the co

Objective : Since posterior circulation vascular lesions are adjacent to important structures such as the brain stem and lower cranial nerves, the acquisition of anatomical information and the careful selection of approaches are essential for the surgical treatment of these lesions. We examined the characteristics and the indications of the far lateral suboccipital approach which exposes lesions without retraction of the brain stem for the treatment of either a vertebral artery (VA) or posterior

Background: Fever is a very common complication that has been related to poor outcomes after aneurysmal subarachnoid hemorrhage (aSAH). The incidence of acalculous cholecystitis is reportedly 0.5%–5% in critically ill patients, and cerebrovascular disease is a risk factor for acute cholecystitis (AC). However, abdominal evaluations are not typically performed for febrile patients who have recently undergone aSAH surgeries. In this study, we discuss our experiences with febrile aSAH patients who

We report the case of a 44-year-old woman who presented with a headache and right sixth cranial nerve palsy. The lesion mimicked a tentorial meningioma in the brain and was investigated using computed tomography and magnetic resonance imaging. Gross total resection was achieved using a subtemporal approach. Histologic examination of the mass revealed the typical tuberculoma such as granulomas with caseous necrosis. Postoperative antituberculous medication led to complete resolution of neurologic

우리나라는 매체별 분산 관리 체계의 한계를 개선하기 위해 2017년 통합환경관리제도를 도입하였으며, 펄프･제지 산업은 2020년 대상 업종으로 지정되어 2024년 통합허가가 완료되었다. 최근 탄소국경조정제도 등 글로벌 환경 규제 강화로 온실가스 감축의 중요성이 커지고 있으나, 오염물질과 온실가스를 분리 관리하는 규제 구조는 사업장에 부담으로 작용하고 있다. 이에 본 연구는 한국과 유럽연합(EU)의 최적가용기법 기준서(BREF)를 비교 분석하여, 국내 펄프･제지 산업에 적합한 기준서 및 제도 개선 방향을 도출하고자 하였다. 공정 분류 체계, 에너지 관리 방식, 최적가용기법 및 최적가용기법 연계배출수준을 중심으로 분석한 결과, EU는 공정 기반 구조와 에너지를 열과 전력으로 구분하여 각각 관리하는 반면, 국내는 제품 중심의 통합 서술로 인해 공정별 에너지 관리에 한계가 있는 것으로 나타났다. 또한 에너지 및 온실가스 항목이 관리 대상에서 제외되어 관련 BAT의 정량적 기준이 부재한 것으

Traumatic intracranial pseudoaneurysm (TIPA) is a very rare disease that is difficult to diagnose and treat and has high mortality and morbidity. Various treatment methods, such as microsurgery and endovascular treatment, have been proposed because TIPA accompanies traumatic brain injury. It is necessary to consider the location and characteristics of the TIPA and the patient's condition. According to previous reports regarding the endovascular treatment of TIPA, most cases were treated with ste

Ventricular aneurysms are very rare. Most ventricular aneurysms are developed at the choroidal artery or a major branch of the circle of Willis. However, in the present study, we will introduce a special case of an intraventricular aneurysm that does not have the parent artery. Previously, a healthy 55 year-old man was admitted to our outpatient clinic with the complaints of headache of 3-month duration and gait disturbance of 2-month duration. On Brain computed tomography and magnetic resonance

Spindle cell lipoma is a subtype of lipoma first defined by Enzinger and Harvey; it accounts for <1.5% of all lipomatous tumors. We present an unusual case of a huge spindle cell lipoma. A 49-year-old man with diabetes mellitus experienced neck pain during sleep because of a huge occipital and upper posterior neck mass that had slowly grown during 4 years. We performed local excision of the tumor, and pathological findings confirmed the diagnosis of spindle cell lipoma measuring 10×9.5×5 cm. The
