  • 설측의 연속호선과 분절호선의 3차원 유한요소 모델에서 레버암의 길이와 미니스크류의 위치를 달리하여 전치부 후방 견인 시의 변위 양상을 비교하였다. 구개 경사면 견인 시, 두 호선 공히 레버암이 짧을수록 전치부의 설측 경사 이동을, 20 mm인 경우 중절치의 치체 이동 및 견치의 치근 이동 양상을 나타냈다. 정중구개봉합부 견인 시의 변위양상은 구개 경사면의 경우와 유사하였으나, 레버암이 20 mm인 두 호선에서 절치의 치체 이동 및 연속호선에서 전치부의 함입 소견을 보였다. 호선 종류에 관계없이 레버암이 길어질수록 절치의 정출은 감소하였고, 구개 경사면에서의 견인인 경우와 함께 견치의 협측 변위가 증가하였으며, 분절호선에서 변위량이 많았다. 연속호선상의 제2소구치는 근심 경사 이동 및 함입 소견을, 대구치는 레버암이 길수록 원심 이동 및 협측 변위를 나타낸 반면, 분절호선상의 구치부도 3차원적 이동 양상을 나타냈으나 변위량은 미미하였다. 전치부 후방 견인 시 레버암 작용에 의해 절치의 경사 이동과 견치의 측방 이동 경향이 있었으며, 치체 이동을 위해서는 약 20 mm의 레버암을 추천할 수 있다. 또한 호선의 종류가 치열 변위 양상 및 변위량에 차이를 나타냈다.

  • Congenital coronary arteriovenous fistula is uncommon disease, and was first described by Krause in 1865. About 20% of the cases, it associates additional congenital heart diseases. A 5-year-old female patient was diagnosed as coronary AV fistula with VSD, and was taken surgical correction under cardiopulmonary bypass. VSD was small and subarterial in type, and the fistula was dilated as adult thumb tip size at its distal portion. VSD was closed directly through the pulmonary arteriotomy and the aneurysmal dilation was opened vertically, then it was obliterated using 5-0, 6-0 prolene continuous suture fashioning into a long slender tube. Postoperative course was uneventful.

  • A case of Annuloaortic Ectasia associated with Marfan syndrome and mitral regurgitation is treated surgically by Bentall`s method and mitral annuloplasty. The Annuloaortic Ectasia is frequently accompanied with Marfan syndrome, its definition is simply explained as the following; the marked dilatation of the sinuses of Valsalva and the aortic annulus as well as the huge aneurysm of the ascending aorta. As the operative finding, the intimal tearing was shown as circular and the both coronary ostia were changed the position into high up. The patient was taken a corrective operation replacing the ascending aorta and aortic valve with a composite graft[St. Jude medical valve 29mm, woven Dacron tubular graft 31mm]. The both coronary ostia were reimplanted on the graft with 4-0 prolene by continuous suture. Mitral annuloplasty was performed. After the operation, the patient developed both spontaneous pneumothorax, he improved state by the closed thoracostomy. He has been doing well, postoperatively.

  • 외상성 횡격막 파열은 방사선 검사로 진단하기가 어려운 경우가 빈번하다. 다발성 손상을 동반한 37세 남자 환자에서 횡격막 파열이 의심되었으나, 흉부 CT 검사에서는 횡격막 파열을 확인할 수는 없었고 진단을 위해 흉강경을 이용한 수술을 결정하였다. 횡격막 신경이 횡격막으로 들어가는 부위로부터 8 cm정도의 횡격막 파열이 있었고, 횡격막 마비를 동반하였다. 작업창을 5 cm크기로 추가하여 만든 후, 파열된 횡격막을 연속 봉합하였으며, 동시에 횡격막 주름성형술을 시행하였다. 수술 3개월후 시행한 흉부 방사선 사진에서 만족할 만한 결과를 보였다.

  • Reconstruction of the pharynx and cervical esophagus is a difficult surgical problem. A successful case of reconstruction of cervical esophagus by free jejunal graft upon a 23-year-old female who had stricture in the pharynx and cervical esophagus after ingestion of hydrochloric acid is presented. This procedure was done after the primary traditional reconstruction with right sided colon had resulted in restenosis due to necrosis of the cervical portion of the graft. A proximal jejunal segment, about 12 cm in length was isolated for free graft preserving its vascular arcade. Both superior thyroid artery and vein were anastomosed to the graft vessels in end to end by continuous suture of 8-0 monophil. Nylon. The postoperative course was uneventful. The patient has been followed for 4 months after operation and she can eat every kind of food without dysphagia. We think free jejunal graft offers an excellent and safe method of reconstructing cervical esophagus and pharynx with definitive advantages over other traditional techniques.

  • A 3-month-old, female Persian cat was presented with sclera mass. The mass was detected after cat's squeals during the playing with a dog before 2 days. On ophthalmic examination, a $2{\times}5mm$ dark purple colored raised mass was observed 1 mm behind the limbus in the right eye. Anterior chamber was filled with blood and epithelial defect was detected at 2 o'clock in the right central cornea. After general anesthesia, resection of the protruded iris was performed with iris scissors and bipolar cautery. Ruptured sclera and conjunctiva were closed with simple interrupted and simple continuous suture, respectively. Also, irrigation and aspiration (I/A) of the anterior chamber was performed to remove blood clot with bimanual I/A handpiece in the right eye. Four months after the surgery, the right eye was recovered completely and menace response was positive in spite of the retinal lesions.

  • This is one case report of successful resection of the aneurysm of the thoracic aorta, which det-ected by thoractomy unexpectedly, in the Department of Thoracic Surgery, Hanyang University Hospital. The patient was a 34 years old woman and subjective complaints was not related with the aneurysm. Chest film showed a small round hazy shadow in the left margin of the upper posterior mediastinum. A saccular aneurysm located on the descending thoracic aorta, 7cm distal to the left subclavian artery and arouse from the antero-lateral wall of the aorta. Excision of the saccular aneurysm was performed by cross clamping the descending aorta above and below the aneurysm, and then the defect of the aortic wall was closed by aortorrhaphy with continuous suture. Crossclamping time was required 15 minute. Histopathologically, the wall of the aneurysm consisted of all layers of the arterial wall, that is, intima, media and adventitia. Postoperative course was uneventful and aortogram showed good continuity of the blood flow of the entire aorta.

  • Congenital coronary arteriovenous fistula is a communication of a coronary artery with one of the atria, ventricles, the coronary sinus, the superior vena cava, or the pulmonary artery. We had a successful surgical experience with 63 year-old-female patient who complained substernal chest pain on exertion for 8 years. On auscultation, a continuous murmur was heard at the left second to third intercostal space along the left sternal border. The right cardiac catheterization was revealed to 4% oxygen step up between right ventricle to main pulmonary artery, and Qp/Qs was 1.3:1. The selective coronary arteriography showed markedly tortuous dilated vessel which originated from left coronary artery draining into the main pulmonary artery. The operation performed to mid portion of tortuous and dilated fistula by multiple ligation with 3-0 Mersilene and suture ligation with pledgetted 3-0 Prolene on distal draining site, Postoperative course were uneventful without any symptoms and complications.

  • Indications of reverse total shoulder arthroplasty (RTSA) have been consistently extended by technical advancements in reverse arthroplasty prosthesis, continuous development of the implants, accumulated experiences and its successful treatment outcomes; accordingly, its use has rapidly increased. RTSA has been performed for a variety of indications, with variable outcomes depending on the initial diagnosis. However, controversial opinions still exist regarding the design of reverse arthroplasty prosthesis (medialized or lateralized design and the neck-shaft angle of the humeral prosthesis), suture of the subscapularis tendon, use of cement during placement of the humeral prosthesis, and surgical procedures; therefore, these should be investigated so that they can be better understood.
