폐 국균종은 폐결핵 등 만성 폐질환으로 인하여 파괴된 폐조직에 국균이 2차적으로 기생하여 발생하는데, 치명적 각혈 등의 증상이 발생할 수 있기 때문에 상당수 증례에서 수술적 치료를 필요로 한다. 이에 최근 10년 간의 수술적 경험을 고찰하고자 한다. 대상 및 방법: 1992년 8월부터 2002년 7월까지 폐절제술 후 병리학적으로 폐 국균종으로 확진된 31명의 환자를 대상으로 호발연령 및 성비율, 주소, 술전검사, 술식의 종류, 지저질환, 술 후 합병증 등을 분석 검토하였다. 결과: 호발연령은 30대와 40대(64.5%)이었으며, 술 전 주요증상은 객혈이었다(27명, 87.1%). 31명 모두에서 술 전 항결핵제 투여경력이 있었으며 19명(61.3%)에서 단순 흉부 방사선 사진상 연부조직 음영이 있는 큰 공동이 관찰되었고 흉부 전산화 단층촬영에서는 31명 모두에서 관찰되었다. 국균객담검사상 37.9%, 혈청 면역 확산 검사상 83.3%의 양성률을 보였다. 폐상엽이 19예(61.3%)로 호발부위였으며 대부분에서 폐엽절제술을 시행하였다. 술 후 병리조직검사상 전 예에서 결핵과 동반되어 있었다. 주요 합병증으로는 농흉 3예(9.7%), 지속적인 공기 누출 2예(6.45%), 사강 2예(6.45%), 술 후 출혈 1예(3.23%) 등이었다. 술 후 사망은 1예(3.23%)로 양측성 폐 국균종에서 수술한 반대쪽의 대량출혈로 사망하였다. 결론: 성비, 나이, 임상증상, 폐결핵과의 연관성, 병변부위 및 수술방법, 합병증 등에 대해서 과거 1963년부터 1992년까지 수술받은 80예와 비교하여 볼 때 큰 차이는 없었다. 진단 기법상 혈청검사는 술 전 아주 높은 양성률을 나타내었고 흉부전산화단층촬영의 높은 진단율은 폐 국균종의 진단과 수술에 매우 중요하다고 사료된다. 복합형 폐 국균종의 경우 흉막유착과 폐문의 경화, 잔존폐의 불완전한 확장 때문에 수술에 어려움이 있어 많은 시간 약물요법과 기관지 동맥 색전술 등의 내과적 치료를 선호하게 되는 데 이와 더불어 공동절개술 등의 비교적 비침습적인 수술방법도 추천되며 최근 합병증의 감소와 더불어 단순형 폐 국균종은 조기에 수술을 적극적으로 고려함이 요구된다.

The orbit has a very special anatomical structure. The complex anatomical structure should be restored when we encounter the patient with orbital wall fracture. Unless these specific anatomy were reconstructed well, the patient should suffer from various complications such enophthalmos, diplopia or orbital deformity. In addition, because the patient has a his own specific orbital shape, individualized approach will be necessary. The aim of this trial is to try to restore the original orbit anatomy as possible based on the mirrored three dimensional CT images based on the computer simulation. Preoperative computed tomography (CT) data were processed for the patient and a rapid prototyping (RP) model was produced. At the same time, the uninjured side was mirrored and superimposed onto the traumatized side, to create a mirror-image of the RP model. In order to restore the missing skipped images between the cuts of CT data because of the thinness of the orbital walls, we manipulated the DICOM data for imaging the original orbital contour using the preoperatively manufactured mirror-image of the RP model. And we fabricated Titanium-Medpor to reconstruct three-dimensional orbital structure intraoperatively. This prefabricated Titanium-Medpor was then inserted onto the defected orbital wall and fixed. Three dimensional approach based on the computer simulation turned out to be very successful in this patient. Individualized approach for each patient could be an ideal way to manage the traumatic patients in near future.

Osteopathia striata with cranial sclerosis (OS-CS) is characterized by linear bone dysplasia at the long bone radiographically and sclerotic change at the cranium. The purpose of this case report is to study the symptoms and treatments of osteomyelitis in a patient with OS-CS. A 41-year-old patient had pus discharge from a fistula at the mental region and increase in radiolucencies with sequestra in panoramic radiograph images. Computed tomography (CT) as well as radiograph images for the whole skeleton were taken. The patient was diagnosed with OS-CS. Sequestrectomy and fistulectomy were performed. The patient recovered and no relapse occurred within six months after surgery. For diagnosis of OS-CS, CT and additional radiograph images for the whole skeleton are required. Because of the increased bone density, this patient is prone to relapse after sequestrectomy. Therefore, the surgeon must minimize trauma with the least incision and exfoliation, and preoperative antibiotics.

Objective : The goal of this study is to evaluate the clinical results in six patients who underwent surgical decompression for the acute subdural hematomas[ASDH] of posterior cranial fossa. Methods : Six patients [five males and one female] who had undergone surgery for ASDH of posterior cranial fossa between 2000 and 2005, were evaluated retrospectively with regard to clinicoradiological findings and surgical outcomes. The mean age was 45.8 years [range $9{\sim}67\;years$]. Results : Preoperative computed tomography showed ASDH on cerebellar hemisphere in four patients and on midline in two. All patients had the associated lesions such as subarachnoid hemorrhage, epidural or subdural hematoma, intraventricular hemorrhage, contusion or pneumocephalus in supratentorial area. Fracture of occipital bone was noted in two patients. Of the four patients who had 13 to 15 of Glasgow coma scale score at the time of admission, three were deteriorated within 24 hours after trauma. Of these three patients, delayed subdural hematoma developed 1 hour after initial normal CT finding in one patient and increased in thickness in another one. Postoperative outcome showed good recovery in three patients and moderate disability in one. Two patients were expired. Conclusion : This study supports that early diagnosis based on strict observation and prompt surgery in the patients with ASDH in posterior fossa will lead to the best results.

Accessory middle cerebral artery (MCA) is an infrequent vascular anomaly of the brain. Cerebral aneurysms associated with this anomalous artery are also very rare. To our knowledge, there have only been ten previous reports of an aneurysm associated with accessory MCA. The authors present two patients with accessory MCA-related aneurysms. A 38-year-old male and a 59-year-old female both presented with sudden-onset severe headache. In both patients, computed tomography (CT) scan revealed subarachnoid hemorrhage. A subsequent angiogram demonstrated an accessory MCA arising from the anterior cerebral artery (ACA) and a saccular aneurysm at the anterior communicating artery (ACoA) complex associated with an accessory MCA. Surgical clipping allowed for complete exclusion of the aneurysm from the arterial circulation. Based on our review of the ten cases of aneurysms associated with accessory MCA documented in the literature, we suggest that accessory MCA-related aneurysms can be classified according to whether the accessory MCA originates from the proximal A1 segment or from the ACoA complex. We also emphasize the importance of precise interpretation of preoperative angiograms and intraoperative precaution in determining the presence of this anomalous artery prior to temporary clip placement.

A 51-year-old woman presented with sudden severe headache, vomiting, and right hemiparesis at first admission. Computed tomography(CT) scans revealed an hemorrhagic density at left basal ganglia. Preoperative cerebral angiography showed no vascular lesion. Under the diagnosis of hypertensive intracerebral hemorrhage(ICH), total extirpation of hematoma was done. The postoperative neurological condition improved gradually and discharged without any neurological sequelae. Two months later, she revisited with headache, vomiting and progressive right hemiparesis. CT scans at second admission showed an irregular rim enhanced mass with central low density with surrounding edema at the initial bleeding area. Repeated craniotomy was performed and the mass was partially removed. The histopathological diagnosis of the specimen was confirmed as glioblastoma. The authors report a glioblastoma, which occurred at initial ICH site and regarded as a brain abscess with literature review.

Neurofibroma is a neurogenic tumor arising from schwann cells or peripheral tissues of nerve sheaths. Neurofibroma rarely occurs as a solitary lesion but mostly occurs as part of neurofibromatosis and reports of neurofibromas developed in the nasal cavity or paranasal sinus are very rare. We report on a case of neurofibroma of the nasal cavity treated by endoscopic surgery. Preoperative computed tomography(CT), and punch biopsy suggested that the tumor was benign neurogenic tumor cofined to right nasal cavity. The tumor was removed with endoscopic surgery completely, and confirmed as neurofibroma by histological and immunohistochemical examination. We discuss the clinical and pathological characters of neurofibroma arising in the nasal septum.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is considered an emerging adjunct therapy for profound hemorrhagic shock, as it can maintain temporary stability until definitive repair of the injury. However, there is limited information about the use of this procedure in children. Herein, we report a case of REBOA in a pediatric patient with blunt trauma, wherein the preoperative deployment of REBOA played a pivotal role in damage control resuscitation. A 7-year-old male patient experienced cardiac arrest after a motor vehicle accident. After 30 minutes of cardiopulmonary resuscitation, spontaneous circulation was achieved. The patient was diagnosed with massive hemoperitoneum. REBOA was then performed under ongoing resuscitative measures. An intra-aortic balloon catheter was deployed above the supraceliac aorta, which helped achieved permissive hypotension while the patient was undergoing surgery. After successful bleeding control with small bowel resection for mesenteric avulsion, thorough radiologic evaluations revealed hypoxic brain injury. The patient died from deterioration of disseminated intravascular coagulation. Although the patient did not survive, a postoperative computed tomography scan revealed neither remaining intraperitoneal injury nor peripheral ischemia correlated with the insertion of a 7-Fr sheath. Hence, REBOA can be a successful bridge therapy, and this result may facilitate the further usage of REBOA to save pediatric patients with non-compressible torso hemorrhage.

Purpose: Closed reduction is most common treatment method for nasal bone fracture but it requires secondary correction operation commonly. For preventing secondary revision, we applied ultrasonography during closed reduction of nasal bone fracture and examined the result of operation. Methods: 80 patients were sorted into 2 groups, ultrasound-guided closed reduction group(n=40) and manual closed reduction group(n=40). We classified the unilateral fracture involving lower 1/2 of nasal bone into type I, the bilateral fracture involving lower 1/2 of nasal bone into type III and the fracture of upper 1/2 of nasal bone into type III. The occurrence rate of overcorrection and undercorrection were evaluated by comparing preoperative and postoperative MDCT(Multi Direction Computed Tomography). Results: In manual closed reduction group, overcorrection were found in 4 patients and undercorrection were found in 3 patients. In ultrasound-guided closed reduction group, overcorrection was not observed and undercorrection was observed in 2 patients. Conclusion: Intraoperative ultrasound evaluation of nasal bone fracture resulted in reduced occurrence rate of secondary nasal deformities, showed easier detection of the fractured site and have superiority upon simple physical examination or simple x-ray.
