  • We have performed 14 single lung transplantation in mongrel dogs transplanting the left lung exclusively from December 1989 to January 1991, in the department of thoracic surgery of Seoul National University Hospital. In the donor dogs, the main pulmonary artery was divided proximal to its bifurcation, and the left atrium was incised freeing the left veins with a generous atrial cuff. We used cold saline in the first 7 transplantation[group I ] and a Euro Collins solution in the remaining 7 transplantations[group II ] as a lung preservatives. The bronchus was divided at two cartilage rings proximal to the upper lobe bronchus take off. In the recipient procedure, we used a Fogarty catheter as a bronchus block. Left atrial anastomosis was performed first using 5 - 0 prolene and the pulmonary artery was anastomosed using 6 - 0 prolene. The bronchus was anastomosed next with 4 - 0 Vicryl interruptly and covered with a greater omentum which had been prepared previously. In group I the three dogs died at eleven hours, 5 days, and 14 days, postoperatively and the remaining four doings were killed at 5 days, 5 days, 6 days, and 12 days, respectively. In group II the two dogs died during the operation, one dog died at 6 hours, two dogs died at 6 days postoperatively. Two dogs were killed at 5 days, and 7 days. No significant difference was noted between the two groups in survival time, lung infiltration of transplanted lungs, and perfusion defects in perfusion lung scans. Of the 8 dogs which died naturally, the causes of death were as follows: 2 cases of sepsis, 2 cases of ventricular fibrillations, 2 cases of malnutrition, and 2 cases of respiratory failures.

  • In some blepharochalasis patients, upper blepharoplasty alone is not satisfactory because of narrow distance between eyebrow and eyelash. On that occasion, eyebrow lift is advisable. There are many methods of classical eyebrow lift, such as direct excision, transblepharoplasty approach, anterior hairline technique, and so on. But they are not so effective, have a tendency to recur and also give rise to side effects; unacceptable scar, facial nerve palsy, sensory loss and hematoma, etc. Some patients who have prominent nasolabial folds, are reluctant to perform face lift procedure due to psychologic or economic burden. The authors performed the eyebrow lift procedure separately or simultaneously with face lift or forehead lift. After making 2 or 3 slit incisions, we passed absorbable suture material, 3-0 vicryl, through suborbicularis oculi fat layer. Then it was passed through subperiosteal plane and fixated to the temporalis fascia. When patients complain prominent nasolabial folds, malar fat pad was elevated also in the same manner. This methods is effective and has minimal complication such as facial nerve palsy, scar, sensory loss. Recurrent tendency was rarely observed during follow-up. Dimples were observed at slit incision sites but they disappeared within 2 or 3 weeks. Eyebrow lift and malar fat lift by absorbable suture elevation with subperiosteal dissection is a simple and less morbid. Because of its effectiveness and little side effect or complication, this procedure can be a useful method.

  • We have performed 28 single lung transplantation in mongrel dogs transplanting the left lung exclusively from November 1989 to September 1991, in the department of thoracic surgery of Seoul National University Hospital. In the donor dogs, the main pulmonary artery was divided proximal to its bifurcation, and the left atrium was incised freeing the left veins with a generous atrial cuff. We used cold saline in the first 7 transplantations and Euro-Collins or modified Euro-Collins solution in the remaining 17 transplantations as a lung preservatives. The bronchus was divided at two cartilage rings proximal to the upper lobe bronchus take off. In the recipient procedure, we used a Fogarty catheter as a bronchus block. Left atrial anastomosis was performed first using 5-O prolene and the pulmonary artery was anastomosed using 6-O prolene. The bronchus was anastomosed next with 4-O vicryl interruptedly and covered with a greater omentum which had been prepared previously. All dogs received cyclosporin A and azathioprine as immunosuppressants and were divided into two group. In the 10 Group I dogs, they survived within 6 days, mean survival time was 66.8$\pm$53.4 hours. In remainder 14 Group lI dogs, they survived above 6 days, mean survival time was 9. 5$\pm$5.6 days. The cause of death were as follows: 2 cases of sacrifice, 2 cases of respiratory insufficiency during operation, 2 cases of arrhythmia immediate postoperatively, 2 cases of bleeding, others in Group I, and 6 cases of sacrifice, 4 cases of sepsis, 3 cases of bleeding, others in Group lI. Results of bronchoscopic findings were obstruction above 50% in 12 cases of 16 performance cases within 5th day. Early chest radiologic haziness were showed, and total lung perfusion defect was frequently showed in both group within 7th day. Main autopsy findings were left atrial and pulmonary arterial thrombi and bronchial obstruction The major histologic findings of Group I were pleural exudate, hemorrhagic infarct, pulmonary congestion, and interesting histologic findings of Group II were 3 cases of perivascular or peribronchial lymphocyte infiltration, 3 cases of hemorrhage infarct, 2 cases of interstitial pneumonitis. The structual change of bronchioles, suggesting bronchiolitis obliterans was not observed due to improper preparation of proximal pulmonary tissue and short term survival times.

  • A female Green iguana (Iguana iguana) was brought to the small animal clinic in Hannover Veterinary school because of anorexia and convulsion. Two months ago, the owner bought two iguanas, one female and one male and had to take a female to the one of local small animal clinic because she, born in 19931 didn't eat well and showed the tremor of the legs. The veterinarian suspected it to have a calcium deficiency and gave an injection of calcium and vitamin D3. But still during the last two months, the female iguana did only eat some lettuce while the other male ate lettuce, fruits and commercial cat-food ($Whiskas^{\circledR}$, Effem, Verden). It was not possible to evaluate the rations of these different "food-components". They are kept in the terrarium with water container. By palpation of the abdomen, hard thing like stone was palpated in the mid-region. The blood test wasn't carried out because of the difficulties of getting blood and because of her bad condition. It was firmly diagnosed as cystic calculus through radiography. Since the animal is in shock state already, the prognosis after surgery was bad. It was assumed to be too late to expect its surviving with the surgery carried out or without it. Cystotomy was performed in the cranial ventral paramedian incision in order to preserve the large ventral abdominal vein in the linen alba region. After two stay sutures ("holding suture" ) with 5-0 polyglactin 910 ($Vicryl^{\circledR}, Ethicon$) on the bladder, cystotomy was carried out and the stone inside was removed. Then, the bladder was closed in one-layer sutures. The abdomen was closed in simple interrupted suture with same material after the instillation of 10 ml saline solution into the abdominal cavity. The cystic calculus was in a size of $5.8{\times} 5.O{\times} 3.5 cm$. The analysis of the stone was carried out in two ways which are the infrared spectroscopy of the stone and quick analysis by $Merckognost^{\circledR}$(Diagnostica Merck, Merck). In the result of the infrared spectroscopy, the stone wee composed of 10% ammonium urate and 90% dihydrated uric acid. This iguana wasn't able to survive.n't able to survive.

  • 후천성 기관식도루는 드문 질환이 지만 생명을 위협하는 병변이며 원인중에는 cuff가 있는 tube를 삽관하여 부적절한 관리하에 장기간 인공호흡기 치료를 한 환자에서 발생하는 경우가 가장 많다. 손상의 기전은 cutt에 의해 기관벽에 압력이 가해져서 허혈성 손상과 더불어 염증성 반응이 더해져 압박된 식도와 비정상적 교통이 생기는 것으로 여겨지고 있다. 환자는 25세된 임산부로 중이염의 합병증으로 세균성 뇌막염이 발생하여 장기간의 인공호흡기 치료중 갑작스런 피하기종과 종격동기종이 발생하여 기관지 경과 CT를 이용해 기관식도루가 발생 했음을 확인후 본과에서 수술적 치료를 시행하였다. 수술은 자동봉합기로 기관의 손상부위를 봉합하고 식도 부위는 vlcyl과 Prolene으로 내외층을 단순봉합하였으며 기관과 식도사이에 흉쇄유돌근 절편을 끼워 넣었다. 수술 후 10일째 식도조영술로 기관식도룬가 완전복구되고 식도기능이 정상임을 확인하였으며 퇴원 후 추적조사결과 환자는 별 문제없이 잘 지내고 있다.

  • 배경: 너스 시술은 누두흉 환자들의 전흉부 함몰을 교정하는 효과적인 수술방법으로 기존의 방법에 비하여 비침습적이다. 하지만 환자의 나이와 기형 형태에 따라 전흉부 함몰은 다양한 양상을 보이는 데, 이에 대하여 고전적인 너스 시술만을 고집할 때 기형 재발, 불충분 교정 등 다수의 합병증이 발생하였다. 따라서 저자들은 고전적인 너스 술식을 몇 가지 관점에서 보완하였다. 대상 및 방법: 1999년 11월부터 2004년 12월까지 135명의 환자와 216건의 수술경험을 후향적으로 분석하였다. 수술 전 컴퓨터 단층촬영, 수술 당시 환자의 연령, 수술방법, 재발을 포함한 합병증 여부를 분석하고, 이를 시술의 개선 전후로 나누어 비교하였다. 결과: 5년 2개월 동안 135명에서 너스 술식을 시행하였으며, 너스막대 제거술 64건, 재발 또는 합병증을 이유로 2번 이상의 너스 술식을 시행한 17건을 포함하여 너스 관련 216건의 수술을 시행하였다. 막대의 삽입위치를 절개부위에서 함몰부의 양족 경계부(늑연골의 최대 돌출부위)로 내측으로 이동시켜 흉곽 지지구조의 손상을 최소화하였고, 막대 성형 시 늑골과 접합하는 부분을 늑골모양에 맞게 성형하여 막대의 미끄러짐 현상을 줄였다. 그리고 막대와 늑골의 고정사를 바이크릴에서 강선으로 전환하고, 성인 환자의 경우, 수술 중 흉골을 견인하는 방법을 추가하였다. 1999년에서 2002년까지 17건에 달하던 재교정과 23건의 합병증이 개선 이후인 2003-2004년에는 재교정 0건, 합병증 3건으로 감소하였다. 결론: 이러한 결과로 미루어 보아, 본원에서 시행한 너스개선 술식은 효과적이었으며, 재발과 합병증을 획기적으로 줄일 수 있었다.

  • Purpose: Since spinal tuberculosis is increasing in prevalence, it appears that a repair of spinal soft tissue defect as a complication of spinal tuberculosis can be a meaningful work. We report this convenient and practical reconstructive surgery which use bilateral latissimus dorsi musculocutaneous advancement flap. Methods: Before the operation, $13{\times}9.5$ cm sized skin and soft tissue defect was located on the dorsal part of a patient from T11 to L3. And dura was exposed on L2. Under the general endotrachel anesthesia, the patient was placed in prone position. After massive saline irrigation, dissection of the bilateral latissimus dorsi musculocutaneous flaps was begun just upper to the paraspinous muscles (at T11 level) by seperating the paraspinous muscles from overlying latissimus dorsi muscles. The plane between the paraspinous muscles fascia and the posterior edge of the latissimus dorsi muscle was ill-defined in the area of deformity, but it could be identified to find attachment of thoracolumbar fascia. The seperation between latissimus dorsi and external oblique muscle was identified, and submuscular plane of dissection was developed between the two muscles. The detachment from thoracolumbar fascia was done. These dissections was facilitated to advance the flap. The posterior perforating vasculature of the latissimus dorsi muscle was divided when encountered approximately 6 cm lateral to midline. Seperating the origin of the latissimus dorsi muscle from rib was done. The dissection was continued on the deep surface of the latissimus dorsi muscle until bilateral latissimus dorsi musculocutaneous flaps were enough to advance for closure. Once this dissection was completely bilateraly, the bipedicled erector spinae muscle was advanced to the midline and was repaired 3-0 nylon to cover the exposed vertebrae. And two musculocutaneous units were advanced to the midline for closure. Three 400 cc hemovacs were inserted beneath bilateral latissimus dorsi musculocutaneous flaps and above exposed vertebra. The flap was sutured with 3-0 & 4-0 nylon & 4-0 vicryl. Results: The patient was kept in prone and lateral position. Suture site was stitched out on POD14 without wound dehiscence. According to observative findings, suture site was stable on POD55 without wound problem. Conclusion: Bilateral latissimus dorsi musculocutaneous advancement flap was one of the useful methods in repairing of large spinal soft tissue defect resulting from spinal tuberculosis.
