흉강입구를 침범한 종양을 근골보존 경흉골병 접근술을 이용하여 수술한 증례를 보고하고자 한다. 우측 상지의 근력 약화를 주소로 69세의 남자 환자가 내원하였다. 단순 흉부 방사선 사진에서 우측 폐 상엽에 기관지 확장증, 만성 결핵과 진균덩이가 관찰되었다. 전산화단층촬영에서 종양이 제 6, 7번 경추와 제 1번 흉추의 척추강내 경막외에 위치하며 우측 흉곽 첨부에까지 연장되어 있었다 신경외과에서 먼저 후궁절제술을 시행하여 척추강 안의 종양을 절제한 후, 흉부외과에서 근골보존 경흉골병 접근술을 통하여 흉강입구를 침범한 종양을 제거하였다. 종양은 혈관외피세포종으로 진단되었으며, 환자는 수술 후 합병증 없이 회복되었다.

Superior sulcus or pancoase tumor refers to any primarty lung cancer locating in thoracic inlet and causing pain in the periscapular region or aim. These originate inperipheral, and involve th extrapulmonary structures more than parenchyma of the lung. We experienced l case of superior sulcus tumor radically resected via anterior transcervical approach, which provide more safe exposure of cervical structures of thoracic inlet than classis posterolateral thoracotomy. Therefore were report this case with review of literature.

Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.

Patients with double-inlet left ventricle usually have a small ascending aorta. In the Norwood procedure, which involves a staged operation, a neoaorta is constructed with a homograft, and the pulmonary artery plays a role in the systemic circulation. Dilatation or aneurysmal changes can occur over time due to the exposure of the neoaorta to systemic pressure, which may induce adverse effects on adj acent structures. We report a rare case of surgical repair for neoaortic root dilataiton with aortic regurgitation, compressing the left pulmohary artery, in a patient who underwent the Norwood procedure.

An 8-year-old intact male Pekingese (weighing 13 kg) was presented for evaluation of chronic coughing. Thoracic radiography found a redundant tissue swelling (protruded on expiration and collapsed on inspiration) on the ventral neck just cranial to the thoracic inlet. Fluoroscopy also identified that the cranial portion of the right/left cranial lung lobe was seen to protrude through the thoracic inlet into the ventral neck on expiration. On the echocardiogram, there were no abnormal jets in all cardiac valves and no dilation in all cardiac chambers. Based on diagnostic imaging studies, the case was diagnosed as cervical lung lobe herniation.

Particulate matter smaller than $10{\mu}textrm{m}$ in aerodynamic diameter (PM10) is known as thoracic particles that are capable of reaching the thoracic region of humans. PM10 is further divided into two size ranges, which are fine particles (nuclei mode plus accumulation mode) and coarse particles, based on different sources and chemical composition. Fine particles can penetrate deep into the alveolar region of the human lungs, while coarse particles be deposited in the upper respiratory system. (omitted)

Background: Although considerable efforts have been made to improve the graft patency in coronary artery bypass surgery, the role of biomechanical factors remains underrecognized. The aim of this study is to investigate the influences of geometric configurations of the bypass graft on hemodynamic characteristics in relation to anastomosis. Materials and Methods: The Numerical analysis focuses on understanding the flow patterns for different values of inlet and distal diameters and graft angles. The Blood flow field is treated as a two-dimensional incompressible laminar flow. A finite volume method is adopted for discretization of the governing equations. The Carreau model is employed as a constitutive equation for blood. In an attempt to obtain the optimal aorto-coronary bypass conditions, the blood flow characteristics are analyzed using in vitro models of the end-to-side anastomotic angles of $45^{\circ}$, $60^{\circ}$ and $90^{\circ}$. To find the optimal graft configurations, the mass flow rates at the outlets of the four models are compared quantitatively. Results: This study finds that Model 3, whose bypass diameter is the same as the inlet diameter of the stenosed coronary artery, delivers the largest amount of blood and the least pressure drop along the arteries. Conclusion: Biomechanical factors are speculated to contribute to the graft patency in coronary artery bypass grafting.

Criss-cross heart which is a cardiac malformation caused by abnormal rotation of the ventricles early in embryonic development, is rare but a double outlet of right ventricle in priss-cross heart is very rare. We experienced a case of criss-cross heart which is situs solidus, concordant atrioventricular connection and double outlet of rig t ventricle with remote ventricular septal defect of perimembranous inlet type. A 4-years old female was diagnosed as a double outlet of right ventricle in criss-cross heart after echocardiography, cardiac catheterization and cardiac angiography. The surgical correction was a intraventricular reconstruction of left ventricular outflow with 314 circle of 20 mm Hemashield vascular graft from the ventricular septal defect to the aorta. The patient had a temporary atrioventricular block but was recovered uneventfully, and a postoperative echocardiogram showed no left ventricular outflow obstruction, no intracardiac shunt.

심실 중격 결손과 폐동맥 협착을 동반한 완전 대혈관 전위를 갖는 환자에서 기존의 Rastelli수술법의 만족스럽지 않은 장기 결과가 보고되는 반면, 최근 들어 대동맥 전위술은 이 질환에서 유용한 수술방법으로 보고되고 있다. 본 증례는 우심실 유입부로 연장된 막성주위형 심실중격결손과 폐동맥 협착을 동반한 완전 대혈관 전위로 진단되어 과거에 체폐단락술을 받았던 2세 남자 환아(체중 9.6 kg)에서 우심실에서 분리한 대동맥 근부를 후방의 좌심실쪽으로 전위시켜 좌심실 유출로 재건술을 시행하고, 판막 도관을 이용하여 우심실 유출로 재건술을 시행하였다. 수술 후 시행한 심초음파 검사에서 양호한 혈역학적 소견을 보여 문헌 고찰과 함께 증례 보고를 한다.

17세 여자 고등학교 학생이 전흉부 동통을 주소로 입원하였다. 약물 치료와 대동맥내 풍선 펌프에도 불구하고 폐부종과 순환 허탈이 악화되었다. 급성 전격성 심근염 추정 진단 하에 좌심실 보조장치를 설치하였다. 유입구 도관은 유방하 좌전개흉술로 좌심이를 통하여 좌심방에 삽입하였고, 좌심이의 일부를 조직검사를 위해 떼어냈다. 유출구 도관은 좌측 대퇴 동맥에 PTFE도관을 간치시켜 삽입하였다. 체외순환 158시간 후 심초음파에서 좌심실의 운동성이 거의 정상으로 회복되었고, 좌심실 보조장치를 성공적으로 이탈할 수 있었다. 면역화학 검사와 중화 항체 검사에서 콕사키바이러스가 확인되었다. 환자는 입원 23일 째 아무런 심부전 증상없이 퇴원하였다.
