배경: 대동맥폐동맥창은 매우 드문 질환이며 동반 심기형을 보이는 경우가 흔하다. 좌우 단락에 의한 과다한 폐 혈류량으로 조기 교정이 필수이나, 정확한 진단과 수술적 교정으로 좋은 결과를 얻을 수 있다. 본 연구에서는 과거 20년간의 경험한 대동맥폐동맥창을 정리하였다. 대상 및 방법: 1985년 3월부터 2005년 1월까지 16명(남 10, 여 6)의 환자가 대동맥폐동맥창으로 진단되어 수술적 교정을 시행하였고,수술당시 평균연령은 $157.8{\pm}245.3$ ($15.0{\sim}994.0$)일이었고, 평균 체중은 $4.8{\pm}±2.5$ ($1.7{\sim}10.7$) kg이었다. 동반 심기형은 동맥관개존증(8예), 심방중격결손증(7예), 대동맥궁단절증(5예), 심실중격결손증(4예), 난원공(3예), 삼첨판막역류증(3예), 승모판역류증(2예), 대동맥판역류증(1예), 대동맥축착증(1예), 좌측상대정맥(1예), 우심증(1예)이었다. 수술 방법은 대동맥폐동맥창의 분리 절단 후 대동맥 부위를 일차 봉합 또는 첩포 봉합하고 폐동맥 부위를 일차 봉합 또는 첩포 봉합하거나(11예), 대동맥폐동맥창의 분리 절단 없이 동맥 내에서 첩포 봉합술을 하거나(3예), 대동맥궁단절 및 대동맥축착을 동반한 환자에서 하대동맥을 직접 대동맥 창에 봉합하였다. (2예). 결과: 사망한 경우가 1예 있었다. 환자는 기관지 분지부에서 상방 2.5 cm정도 심한 협착과 기관유래기관지가 우상엽과 연결되어 있었던 경우로, 기관성형술(sliding tracheoplasty)시행 후 과다 출혈로 술 후 5일째 사망하였다. 복잡 대동맥폐동맥창 환자의 입원 기간 및 중환자실 체류 기간이 더 길었으며, 재수술(5예)과 합병증의 빈도도 더 높았다. 재수술은 좌폐동맥 협착(4예), 우폐동맥 협착(2예), 주폐동맥 협착(1예) 등이 원인이었다. 평균 추적 기간은 $6.8{\pm}5.6$ (57.0일$\sim$16.7년)년이었고, 생존 환자의 추적 기간 동안 NYHA 기능분류는 모두 I이었다. 결론: 연구자 등은 대동맥폐동맥창으로 진단된 16명의 환자에 대한 분석을 통해 조기 수술로 술 후 양호한 결과를 확보할 수 있음을 확인하였으며, 동반 심기형의 적절한 수술적 교정이 만기 예후를 좌우하는 것을 알 수 있었다. 수술 후 재협착의 빈도를 줄이기 위한 수술 전략의 재고가 요구된다.

This is to report a case of bronchgenic cyst. While most of the bronchogenic cysts reported in the literature so far were located either in the lung parechym or in the mediastinum near the tracheal bifurcation or main bronchi. the cyst presenting in this study was originated in the wall of the esophagus and was reported to be very rare. The cystic tumor was found accidentally by X-ray fluoroscopic examination of the esophagus and stomach in the patient with gastric hemorrhage. X-ray study revealed that the cystic tumor was oval in shape and located in the left posterolateral wall of the esophagus in the thoracic lower third. Two surgical operations, gastrectomy for gastric hemorrhage and the resection of the cystic tumor, were carried out separately. Gastrectomy including the removal of prepyloric ulcer by the Billroth II type procedure was performed in regular fashion, and the cystic tumor was resected radically without any injury of the mucous membrane of the esophagus. The cyst removed appeared to be filled with mucinous material, and histological examination identified the tumor as a bronchogenic cyst with ciliated epithelial internal lining. Postperative course of the patient was uneventful.

Postoperative airway aspiration is not uncommon in patients with head and neck cancer. Airway aspiration has serious consequences, such as swallowing disorders, nutrition-related health problem, or reducing the quality of life due to maintenance of tracheal or nasogastric tubes. The postoperative oropharyngeal defect due to the surgery may interfere with normal swallowing reflex, or the laryngeal dysfunction caused by radiation therapy may cause severe airway aspiration, which may lead to complications such as dyspnea and pneumonia. Complete removal of the disease is also important in the treatment of head and neck cancer, but it is necessary to select a method to avoid and predict the occurrence of airway aspiration according to the treatment method. The most important factor to prevent airway aspiration after surgery is to preserve the proper volume of the oropharynx and to preserve at least one of the cricoarytenoid joint function. It is also the most effective way to reduce additional complications by seeking appropriate surgical treatment according to airway aspiration status. The purpose of this study is to review the operative methods that can induce airway aspiration and consider the prevention and treatment strategy through review of the literature.

Nasotracheal intubation is commonly performed under general anesthesia in oral and maxillofacial surgery. For the convenience of surgery, nasal Ring-Adair-Elwyn (RAE) tubes are mainly used. Because the nasal RAE tubes were bent in an "L" shape, the insertion depth was limited. Particularly, it is necessary to accurately determine the appropriate depth of the RAE tubes in children. Several types of nasal RAE tubes are used in the medical market, which vary in material and length. We performed endotracheal intubation using a nasal RAE tube for double-jaw surgery, but air leakage persisted even when the air pressure in the cuff was increased. When checked with a laryngoscope, it was confirmed that the tube was pushed out, and the cuff was caught on the vocal cords, causing air leakage. Since inserting the tube deeply did not solve the problem, replacing it with a nasal RAE tube (Polar^TM, Preformed Tracheal Tube, Smith Medical, Inc., USA) did not cause air leakage; thus, we reported this case.

The esophageal cyst result from a wrong cleavage of the primitive gut in the 4 weeks embryo. In embryo and after seperation of the tracheal diverticulum, the esophagus is lined with ciliated cells which are able cover a "cystic duplication". It is often difficult to distinguish between the bronchogenic and the esophageal cyst. Pathological findings showed the presence of a ciliated epithelium without cartilage which was diagnosed as an esophageal cyst. The patient was 21 year old man for evaluation of the cyst in the posterior mediastinum. The cyst was located the intramural esophagus. Microscopically, the cyst was lined with ciliated columnar epithelium and there was no evidence of cartilage. The cyst was confirmed as the intramural esophageal cyst.geal cyst.

There are a few case reports describing persistent seizure following propofol. A 45-year-old female underwent operation of mastoidectomy and tympanoplasty. She had no personal or family history of epilepsy. Anesthesia was induced with propofol and rocuronium, and maintained with sevoflurane-remifentanil after tracheal intubation. Any event was not noted during surgery. Seizure-like movement and shivering were developed after surgery in recovery room. Symptom was relieved by benzodiazepines, especially lorazepam. She was discharged in the 9th postoperative days without any sequelae.

Acquired, nonmalignant tracheoesophageal fistula is an uncommom and difficult problem to manage. The most commom cause is a complication of endotracheal or tracheostomy tubes. Most are diagnosed while patients still require mechanical ventilation. The principle of treatment is two stage operation. First, new tracheostomy tube is placed so that the baloon is below the fistula, and gastrostomy and feeding jejunostomy are made for the drainage and feeding. Finally after weaning from the mechanical ventilation, tracheal resection and reconstruction are made, and the esophageal defect is closed in two layers and a viable strap muscle interposed into the two suture site to prevent recurrence. Recently, we experienced a case of acquired nonmalignant tracheoesophageal fistula which was developed during mechanical ventilation. She was successfully treated with the above two stage operation.

Neurofibromatosis [Von Recklinghausen`s disease] is a rare Mendelian dominant disease, which shows multiple generalized symptoms and signs at various sites [Ex Skin, Bone, Nerve, Endocrine, Mediastinum rarely Lung, etc.]. We experienced one case of neurofibromatosis which has typical skin lesions [cafe-au-lait, multiple nodules, axillary freckling] with neurofibrosarcoma [malignant change from mediastinal lesion]. Patient was admitted our department because of recently developed severe dyspnea which was probably due to main tracheal compression by mediastinal neurofibrosarcoma. After successful removal of mediastinal mass dyspnea disappeared completely. Patient`s postoperative course was uneventful, and the patient was discharged 14 days after operation.
