Rupture of a bronchus is an unusual result of blunt trauma to the chest. We experienced a case of bronchial rupture caused by blunt chest trauma without external wound or rib fracture. This case was a 13 years old male who was elementary school student. He was compressed on anterior chest by basket ball goal post being failed down on the afternoon of admission day. After this accident, he was suffered from progressive dyspnea and chest pain. The bronchial rupture was confirmed by bronchogram, The operation was performed through standard posterolateral thoracotomy incision along the 5th rib course. The right upper lobe bronchus and intermediate bronchus was completely transected. The right upper lobectomy was done. The ruptured intermediate bronchus was connected direct simply. Post-operative course was uneventful. Thus we report this case of traumatic bronchial rupture with review of literature.

Domestic insurance claims were statistically investigated to analyze the elderly driver's accident patterns and injury types in side impact crashes. Medical treatment records and accident vehicle damage photos have been surveyed for 5,419 cases. The results of our statistical analysis showed that the thorax injury risk of the elderly drive group is 8.8 and 4.0 times higher than that of the young and middle age group respectively. Diagnosis showed that most thorax injuries were caused by rib fracture. The head injury risk of the elderly female driver group seemed to be higher than that of the younger female driver group, however, statistical test has not been conducted because of the lack of number of samples for elderly female accident.

Since cardiac pacemaker was first totally implanted by Chardack, Gage and Greatbatch [1966], the electrical circuity of the cardiac pacemaker has been improved, modified, and refined. The problem of transvenous electrodes, however, is still remained; this may be due to electrode displacement, exit and/or entrance block, lead fracture and insulation defects. In permanent cardiac pacing, Irreversible loss of function of the transvenous electrode catheter eventually requires insertion of new lead. Authors now report one case that disclosed easy displacement of electrode tip in early phase of implantation and then two years and five months later, malfunctioning electrode could not be withdrawn from the cardiovascular system because it has become firmly enclosed by fibrous tissue along its course from the vein tract to the right ventricle. Under such circumstances, the electrode catheter tip was left in tricuspid annulus after being sutured at its entrance and burying the loop of lead in generator pocket. New other one electrode was then reimplantation through left external jugular vein.

We report a case of leaflet embolization of central leaflet fracture a 31mm mitral Edw-ards-Duromedics prosthesis. A leaflet was fractured to two segments, a larger one embolized to right common iliac artery and a smaller one to left femoral artery, respectively. Patient was reoperated with 29mm mitral Carbomedics prosthesis and incidentally found of smaller segment in left femoral artery at cannulation site. The embolectomy was done 15 days after cardiac operation through midline abdominal incision, Leaflet escape of a mitral Edward-Duromedics prosthesis is a rare, potentially curable mode of valve failure. After mechanical valve replacement, unexplained heart failure and acute pulmonary edema, mechanical valve failure should be suspected. Correct interpretation of clinical signs, symptoms and fluroscopy should allow early diagnosis of leaflet escape and prompt surgical therapy.

The rupture of tracheobronchial tree caused by non penetrating blunt trauma is being increased in incidence though it is still rarely occurred on now Because this type of injury is uncommon, a high index of suspicion should be maintained in all crush injuries involving the chest. Early diagnosis and primary repair not only restore normal lung function but also avoid the difficulties and complications associated with delayed diagnosis and repair. We experienced a case of tracheobronchial rupture caused by non penetrating blunt chest trauma without rib fracture. The patient was a 16 year old male who was a high school student. He was compressed on anterior chest by hand ball goal post being failed down on the morning of admission day. After this accident, he was suffered from progressively developing dyspnea and subcutaneous emphysema on face, neck and anterior chest. The diagnosis, tracheal rupture, was made by chest CT and bronchoscopy. After right thoracotomy, the ruptured site was directly closed by using interrupted suture. Post-operative course was uneventful. Thus we report this case of traumatic tracheal rupture with review of literature.

세마리의 개가 골절을 주증으로 내원하였다. 증례 1(1.8 kg의 5개월령 암컷 몰티즈)과 증례 2(3.0 kg의 6개월령 암컷 푸들)는 좌측 후지의 체중부중을 하지 않는 파행을, 증례 3(3.3 kg의 나이를 알 수 없는 암컷 잡종견)은 좌측 전지의 체중부중을 하지 않는 파행을 보였다. 정형외과 검사시 손상받은 부위의 통증, 염발음, 촉진상의 불안정성과 광범위한 연부조직 부종을 보였으며 신경학적 이상소견은 관찰되지 않았다. 방사선 검사상 증례 1와 2에서 좌측 근위 경골 골간단과 비골의 골절이, 증례 3에서는 좌측 근위 요골 골간단과 척골의 골절이 관찰되었다. 모든 증례는 골절편이 짧은 관절주위 폐쇄형 골절이었다. 술 중에는 투시장치를 이용해 2개 또는 3개의 원형고정장치의 적절한 위치에 삽입하였다. 술 후 방사선 사진에서 골절부위의 적절한 배열과 위치를 확인하였다. 방사선학적으로 5주에서 14주 사이에서 골유합이 확인되었고 임플란트의 고정 실패나 핀 주변 감염은 나타나지 않았다. 기능상 결과는 모든 증례에서 매우 좋은 것으로 나타났다. 따라서, 원형외고정장치는 뼈판이나 외고정장치를 사용할 수 없는 짧은 골절편을 가진 관절주의의 골절정복에 성공적으로 이용할 수 있을 거라 사료된다.

Rib fixations for flail chest or displaced rib fractures are not a new technique. However, reports on rib fixations involving costal cartilage fractures are very few and surprisingly there are no reports of internal fixations involving only the costal cartilage in the English literature. The diagnosis is difficult and the necessity of the procedure may be quite controversial. Placing plates in screws into the costal cartilage alone may seem unstable and easily dislodged or stripped through the cartilage. We report a 31-year-old male scuba diver instructor who underwent rib fixations over his 7th and 8th costal cartilage ribs for severe pain. The procedure was done with conventional plates and screws. He had the plates and screws removed 2 months later due to lingering pain, but with them removed he is now quite happy with the results without pain. The procedure for fixation of painful overlapped costal cartilage is quite simple and can be done with the usual conventional methods, fixating plate and screws directly over the cartilage alone without fixation over the bony rib.

Background: Minimally invasive direct coronary artery bypass surgery(MIDCAB) has been increasing in interest along with the new techniques in myocardial immobilization for easier and safer procedures. Until the opening of the era of new techniques, adequate accuracy and good patency of grafts were debatable. Our experiences of MIDCAB were studied according to the stages of technical developments. Material and Methods: Since March 1996, 55 patients have undergone MIDCAB procedures. The patients of off-pump CABG(no cardiopulmonary bypass under full sternotomy) were excluded from the study. In the early experience(Stage I), a left anterior small thoracotomy through the left parasternal incision was performed(n=6); then an approach through the lower partial sternotomy was used(Stage II, n=33); and recently, a chest wall elevator for harvesting the internal thoracic artery and the foot plate for myocardial immobilization have been used(USSC, Norwalk, CT)(Stage III, n=16). Result: The surgical procedures of four patients in the Stage II group have been converted to conventional bypass because of the deeply seated left anterior descending coronary artery in two patients, fracture of the calcific lesion in the right coronary artery in one patient, and a cardiogenic shock during hypothermia in the other patient with ventricular dysfunction. Two patients in stage II experienced symptomatic recurrences after surgery and restenosis was verified on angiocardiography. They were managed by interventional procedures. All the other patients were doing well without symptoms, except one patients in Stage II who underwent PTCA procedure for a lesion in the circumflex artery during the follow up period. Conclusion: The new and specialized devices are essential to the development of MIDCAB surgery. MIDCAB and the hybrid procedures in multi-vessel disease are on the way to further development. So far, our experience is limited only to a single device among the many new devices for the purpose.
