흉벽에 발생한 악성 말초신경초종은 미국에서 Mark등a(1991)이 17례를 보고하였으나 한국에서는 아직까 지 발표된 예가 없다. 악성 말초신경초종은 악성 연부 육종의 10%에서 발생되며 대개 20세에서 50세 사이에 발생한다. 악성 말 초신경초종은 주로 좌골신경, 상완신경총, 천추총과 연관되어 발생하며, 가장 흔한 발생위치는 상지와 하지 의 근위부, 체간 등이며 드물게는 두경부에도 발생한다. 악성 연부조직 육종의 치료는 저급육종(low grade sarcoma)의 경우는 종양의 절제만으로 치유 가능하나 고급육종(high grade sarcoma)의 경우는 광범위 절제가 요구된다. 저자의 경우에는 50세 남자에서 다발성 거대종괴가 좌측 흉벽에 광범위하게 있었으며 병리소견상 저급 악 성 말초신경초종으로 판명되었다. 종괴들을 절제한후 발생한 흉벽결손은 15$\times$8 cm정도 였으며 Teflon을 이용하여 재건하였다. 수술후 환자 는 큰 문제 얼이 회복되었다.

A 7-year-old, intact female Yorkshire terrier dog was presented for coughing, anorexia, chest pain and dyspnea. Right lateral thoracic radiograph demonstrated a large mass shape on the heart base with decreased cardiac silhouette and severe right deviation of the trachea with the heart shifted to the left thoracic wall was observed on the ventrodorsal thoracic projection. Echocardiographic examination revealed a large rounded mass compressing left atrium around the heart base without signs of pericardial effusion. On computed tomographic (CT) findings, sagittal CT images depicted the possibility of cranial vena caval invasion and heart base involvement of the mass associated with biatrial compression. Dorsal CT image revealed the right deviation of trachea due to the heart base mass and markedly shrunk lung space was detected on the transverse CT image. Because the dog suddenly had died during the recovery from anesthesia after finishing CT scan, necropsy was performed. On gross findings, a large and lobulated mass was located at the base of the heart. A poorly-demarcated, infiltrative, multilobulated tumor composed of polyhedral cells in solid cellular sheets was confirmed based on histopathologic examination. This dog was diagnosed as a chemodectoma. This case report describes the clinical findings, diagnostic consistency of thoracic radiography, echocardiography and CT, and histopathologic confirmation in a spontaneously occurring chemodectoma with a Yorkshire terrier dog.

Background: Pectus excavatum (PE) is the most common chest wall deformity. The Nuss Questionnaire modified for Adults (NQmA) is a disease-specific health-related quality of life assessment tool for patients with pectus deformities. The aim of this study is to adapt the NQmA into Turkish. Methods: Two hundred and sixty-five patients with PE were participated, with an age range of 14 to 29 years. All patients underwent a physical examination and had not undergone corrective surgery. The Turkish version of the NQmA was completed by patients and their parents. Results: The content validity index based on expert opinions was 91% for the patient questionnaire and 96% for the parent questionnaire. The Cronbach's alpha value for the NQmA was found to be 0.805 for the patient questionnaire and 0.800 for the parent questionnaire. Exploratory factor analysis was used to assess construct validity. Two factors explained 51.1% of the total variance in the patient questionnaire (psychosocial: 31.145%, Cronbach's alpha=0.818; physical: 19.955%, Cronbach's alpha=0.862). In the parent questionnaire, two factors explained 51.422% of the total variance (psychosocial: 26.097%, Cronbach's alpha=0.743; physical: 25.325%, Cronbach's alpha=0.827). Construct validity was confirmed by confirmatory factor analysis. Conclusion: The Turkish version of the NQmA was found to be valid and reliable for the assessment of quality of life in patients with PE.

흉부 대동맥의 외상성 파열은 두부 손상 다음으로 흔한 교통사고의 사망원인으로 약 85%의 환자가 병원 도착 전에 사망한다. 가장 흔한 기전은 고속의 차량이 충돌 등으로 인한 급작스런 감속에 의해 발생되며 대동맥 협부가 전체 대동맥 손상의 95%에 해당된다. 또 다른 기전으로는 흉부 압박 손상에 의해 골절되어 전위된 흉골병과 흉부 척추 사이에 대동맥이 끼이면서 나타날 수 있는데 이로 인해 흔하지 않은 위치의 대동맥벽의 내막이 파열된다. 저자들은 감속사고가 아닌 흉부 압박에 의해 대동맥궁이 파열되어 박리된 증례에 대해 집중적인 내과 치료 후에 지연 수술로 완전 순환정지 하에 뇌보호를 시행하면서 상행 대동맥의 일부와 대동맥궁을 인조혈관으로 치환하였기에 보고하는 바이다.

대동맥 벽내 혈종은 대동맥 내벽의 열상 등 손상이 없으면서 대동맥의 혈관벽내의 출혈로 정의되며 고전적인 대동맥 박리로 진행할 수 있는 질환으로 대동맥 박리의 변형된 형태로 여겨지기도 한다. 대동맥 벽내 혈종은 높은 이환율과 사망률을 보이나 궁극적 치료는 아직 확실하지 않다. 하지만 상행 대동맥에 발생한 대동맥 벽내 혈종은 대동맥 파열과 심낭 압전의 위험성으로 인해 보통 수술적인 치료가 고려되고 있다. 저자들은 실신을 주소로 내원한 71세 남환에서 대동맥 벽내 혈종 1예를 수술 치험 하였다. 잘못된 진단으로 인해 응급실 내원 5시간 뒤 시행된 대동맥 단층 컴퓨터 촬영 검사 결과 상행대동맥 벽내 혈종과 심낭 압전 소견이 동반되어 있었으며 이로 인해 급성 신부전, 허혈성 장기손상의 합병증이 발생하였다. 응급 수술로 상행대동맥 및 대동맥궁 치환술을 진행하였고 환자는 수술 14일 뒤 합병증 없이 퇴원하였다.

Purpose: Sternal fractures after blunt thoracic trauma can cause significant pain and disability. They are relatively uncommon as a result of direct trauma to the sternum and open reduction is reserved for those with debilitating pain and fracture displacement. We reviewed consecutive 11 cases of open reduction and fixation of sternum and tried to find standard approach to the traumatic sternal fractures with severe displacement. Methods: From December 2008 to August 2010, the medical records of 11 patients who underwent surgical reduction and fixation of sternum for sternal fractures with severe displacement were reviewed. We investigated patients' characteristics, chest trauma, associated other injuries, type of open reduction and fixation, combined operations, preoerative ventilator support and postoperative complications. Results: The mean patient age was 59.3years (range, 41~79). The group comprised 6 male and 5 female subjects. Among 11 patients who underwent open reduction and fixation for sternal fracture with severe displacement, 6 cases had isolated sternal fractures and the other 5 patients had associated other injuries. Sternal fractures were caused by car accidents (9/11, 81.8%), falling down (1/11, 9.1%) and direct blunt trauma to the sternum (1/11, 9.1%), respectively. 3 of the 7 patients (42.9%) who underwent sternal plating with longitudinal plates showed loosening of fixation. Otherwise, none of the 4 patients who underwent surgical fixation using T-shaped plate had stable alignment of the fracture. Conclusion: Sternal fractures with severe displacement need to be repaired to prevent chronic pain, instability of the anterior chest wall, deformity of the sternum, and even kyphosis. In the present study, a T-shaped plate with a compression-tension mechanism constitutes the treatment of choice for displaced sternal fractures.

Objective : To evaluate the anatomical parameters that must be considered when performing thoracic transpedicular or extrapedicular screw fixation. Methods : We selected 958 vertebrae (1,916 pedicles) from 98 patients for analysis. Eight parameters were measured from CT scans : the transverse outer pedicular diameter, transverse inner pedicular diameter, length, angle, chord length of the pedicles and the transverse width, angle, and chord length of the pedicle-rib units. Results : The age of the patients ranged from 21 to 82 years (mean: 48.2 years) and there were 57 men and 41 women. The narrowest transverse outer pedicular diameter was at T5 (4.4 mm). The narrowest pedicle length was at T1 (15.9 mm). For pedicle angle, T1 was 31.6 degrees, which was the most convergent angle, and it showed the tendency of the lower the level, the lesser the convergent angle. The chord length showed a horizontal pattern with similar values at all levels. For the PRU width, T5 showed a similar pattern to the pedicle width at 13.4 mm. For the PRU angle, T1 was the largest angle at 46.2 degrees and the tendency was the lower the level. the narrower the angle. For chord length, T1 was the shortest at 46.9 mm and T8 was the longest at 60.1 mm. Conclusion : When transpedicular screw fixations carried out at the mid-thoracic level, special care must be taken because there is a high chance of danger of medial wall violation. In these circumstances, extrapedicular screw fixation may be considered as an alternative treatment.

The cellular change of the pulmonary tuberculous lesions may be divided into two groups,exudative and proliferative form by their course and fate. In the most cases, the patients usually have very much complex type of cellular changes. Therefore, the shadows of the chest films in pulmonary tuberculosis are also much variable in nature. And Daniel said that knowledge of the pathology of tuberculosis and an appreciation of the method of progression and healing are essential to proper interpretation of the films. Author, having reviewed 33 cases of resected tuberculous lung obtained in N.M.T.H. for one year from Oct. '75 to Sep. '76 by surgical managements, classified the Pathological findings such as: 1) caseation only, 2) tuberculoma, 3) atelectatic lung 4) cavitary lesion and 5) atelectasis with cavity, and examined the relationship between the roentgenological characteristics of the chest films and the pathological process of tuberculous lesions of the resected lungs, The result were obtained as follows. (1) Tuberculoma was commonly appeared in $S_2$ segment in right and $S_6$ segment in left. (2) Atelectasis and destroyed lung were more commonly appeared in left lung than right, and their containing rate of cavity was 82%. (3) Cavities were mostly appeared in $S_1$ and $S_2$ segments of both lung and the appearance-rate of cavity on $S_6$ segment was higher in left than right. And among the cavitary lesions of the resected lung, cavity was not seen in the preoperative chest films in 22%. (4) The configuration, thickness and sharpness of the walls of cavities, which revealed the cavitary shadows in the preoperative chest films, were mostly depended on the degree of increased collagenous fiber of the wall, existence of perifocalitis, and more or less of the caseous masses on the inner surface of the cavity wall.
