본 연구는 개에서 건삭파열로 유발한 급성 이첨판 폐쇄부전 모델의 혈류역학적 변화를 관찰하는 것이다. 이 연구는 10마리의 정상 심장기능을 가진 비글견에서 실시되었다. 직접혈압측정법과 Swan-Ganz 카테터를 통해 건삭을 실험적으로 파열시키는 기간동안 혈류역학적 지표 변화를 진행하였다. 이첨판 폐쇄부전 모델을 만들기 위해 5번 늑간으로 접근하여 관절경에 사용하는 작은 훅나이프를 사용하여 건삭을 파열하였다. 수술 중 칼라 도플러 영상 검사를 통해 이첨판 역류를 확인하였다. 혈류역학적 지표를 측정한 결과 폐모세혈관쇄기압은 유의적으로 증가하였지만, 평균동맥압, 정맥압, 폐동맥압, 심박출량, 심박출 지수는 건삭 파열 후에 유의적으로 감소한다는 것을 발견하였다. 이것은 건산파열로 인해 좌심실로 부터 역류된 혈액이 좌심방에 과부하를 일으킨다는 것을 나타내는 것이다. 본 연구를 통해 개에서 급성 이첨판 폐쇄부전 모델을 만드는데 있어 건삭파열방법이 효과적인 것을 알 수 있었고, 이첨판 역류 유발 후 시간이 지나면 만성 이첨판 부전증으로 진행할 수 있을 것으로 생각되며, 차후 판막의 만성적 변화 양상을 연구하는데 도움을 줄 수 있을 것으로 생각됩니다.

Traumatic rupture of the main bronchus is comparatively very rare. With the advent of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. Rupture of the bronchus is an unusual result of nonpenetrating trauma to the chest. Early recognition of bronchial rupture and emergency thoracotomy and management is essential for reducing of morbidity, mortality and late complications. We experienced 3 cases of bronchial rupture caused by nonpenetrating chest trauma with or without rib fracture. Patients were suffered from dyspnea and chest pain. After closed thoracostomy, corrective surgery was performed. Postoperative courses were uneventful and discharged without any complication.

Bilateral traumatic rupture of diaphragm is very rare. One case due to car accident is reported. Preoperative chest X-ray revealed the diaphragm rupture in the left side and the hemothorax in the right side. During the completion of left diaphragm repair through left thoracoabdominal incision, right diaphragm rupture was found incidentally. Left diaphragm was repaired using pledgets which were anchored at the thoracic wall. Right diaphragm was also repaired by interrupted Halsted sutures through seperated right thoracotomy. Postoperative course was uneventful.

The injuries to the bronchi have been reported with increasing frequencies. The most common cause of such injuries is compression or crushing chest trauma. Early diagnosis and emergent repair should be done for the good prognosis. We report 3 cases who had bronchial injuries after traffic accident. Our operative procedures were a primary bronchial repair for 17 months old boy, a pneumonectomy for delayed recognition and a bronchoplasty procedure 63 days after trauma. All these bronchial ruptures were successfully treated and discharged.

A case is presented of a steering wheel Injury to the chest which developed right atrial free wall rupture and cardiac tamponade without rib fractures or hemo-pneumothorax. A 30 year old man who sustained, blunt chest trauma by steering wheel injury to his chest developed right atrial rupture and cardiac tamponade. Pericardiocentesis was performed and cardiac tamponade was confirmed. After a median sternotomy, large right atrial free wall laceration [about 8cm] was noted. He was placed on cardiopulmonary bypass. The laceration wound of right atrium was closed with a 2 rows of continuous suture. Recovery was uneventful. The patient has returned to his previous level of activity.

The tracheobronchial rupture from blunt trauma is an uncommon injury with a variety of clinical presentations. Most of traumatic tracheobronchial tears occur within 2.5cm of the tracheal carina; lobar or segmental bronchi are rarely affected. Recently we experienced one case of traumatic rupture of right middle lobar bronchus in a patient who had fallen from a bicycle. Bronchoscopy showed linear disruption of the right middle lobe bronchus at its bifurcation site. Emergency right middle lobectomy was performed. The patient was recovered without any sequelae.

Over the past 3.5 years, 5 cases with ruptured sinus of Valsalva were operated upon at Asan Medical Center. Four patients were congenital and 1 traumatic. Coexistent lesions included 2 subarterial VSD, 3 AR requiring procedures [2 AVR, 1 valvoplasty], 2 subaortic membranes, 1 PDA,and 1 bicuspid AV. The communication is noncoronary sinus to RA in I and fight Coronary sinus to RV in the other 4 patients. The ~rstula was repaired through the aorta whenever possible and reinforced through the right sided chamber. There are no surgical mortality and, no recurrence of rupture yet.

Bichamber cardiac rupture is less frequent compared to unichamber cardiac rupture. We report a patient who was successfully treated after the diagnosis of penetrating stab wound of both ventricles. The key to improved outcome of management of cardiac trauma lies in the rapid transportation to a general hospital where cardiac surgery is available. Aggressive primary intervention and immediate operation are also major factors.

Although blunt traumatic cardiac rupture is an uncommon injury, it can be associated with a high mortality rate. Two cases of cardiac rupture in blunt trauma patients are described herein. In those cases, applications of mechanical support devices such as ECMO (extracorporeal membrane oxygenation) and early surgery for exploration under cardiopulmonary bypass may be helpful for treating blunt chest trauma patients.

We have experienced two cases of traumatic subclavian artery rupture at the department of thoracic and cardiovascular surgery, Youngdong Severance hospital, Yonsei University college of medicine. One was combined with brachial plexus injury and the other was combined with brachial plexus injury and subclavian vein rupture. They were treated with graft interposition after segmental resection of ruptured subclavian artery and neurorrhaphy for brachial plexus injury. Post operative courses were not eventful.
