  • Background and Objectives : The aim of the this study is to determine the efficacy of an external prosthesis made of ringed Polytetrafluoroethylene to prevent Postanastomotic stenosis after surgical correction of extensive tracheal defects in rabbits. Materials and Methods : Thirty rabbits were used, divided into two groups of 15 animals each. Group A rabbits underwent resection of six-ring segments of the cervical trachea and tracheal end-to-end anastomosis. The Procedure used in group B was similar to that used in group A. but the tracheal anastomosis was supported by an external ringed polytetrafluoroethylene prosthesis. After six months, rabbits were killed and tracheas were resected and then compared the postanastomotic tracheal stenosis using morphometry. Results : Anteroposterior diameter, transverse diameter, cross sectional area and intra luminal perimeter of trachea was greater in group B than group A. Also inflammatory changes of mucosa and submucosa were greater in group A than group B. Conclusion : A ringed PTFE as a external stent was effective to prevent tracheal stenosis resulting from the extensive tracheal resection and tracheal reconstruction in rabbits.

  • A 6-month-old mature intact female Siamese cat presented with exertional dyspnea. Diagnostic studies revealed pleural effusion, grade 4/6 left basal systolic murmur, deep S-wave in electrocardiograph leads I, II, and III, cardiomegaly with pleural effusion on radiography, pulmonic systolic (~5.8 m/sec) and tricuspid (3.6 m/sec) regurgitant jets, atrial septal defect, and a hypoplastic right outflow tract. Based on these results, the case was diagnosed as pulmonic stenosis with atrial septal defect. To the best of our knowledge, this is the first case report describing pulmonic stenosis with atrial septal defect in a cat in Korea.

  • Congenital esophageal stenosis is a rare disease in childhood. By virtue of its complex embryological development, the esophagus is the site of many congenital abnormalities. Congenital Esophageal stenosis is one tenth as rare as tracheoesophageal fistula with esophageal atresia and is very rare in the cervical esophagus, which mostly occurred below mid-esophagus. Congenital esophageal web may be caused by the resorption failure of the epithelium following the vacuolization stage in embryonic development in the esophagus. Recently, we experienced 1 cases of congenital esophageal web, as the symptoms of life-long dysphagia. According to her history of dysphagia, radiologic and clinical findings, her esophageal stenosis was considered as congenital. For dilatation and relief of dysphagia, she underwent the Heineke-Mikulicz type of esophagoplasty. The results of surgical treatment were relatively good without any clinical events. So we reported it with its literature review.

  • Congenital supravalvar aortic stenosis is an obstruction caused by localized or diffuse narrowing of the aortic lumen commencing immediately above the aortic valve. We experienced a case of diffuse supravalvar aortic stenosis involving ascending aorta from just above the sinuses of Valsalva to the proximal l cm of the innominate artery. Supravalvar aortic stenosis in this patient, in contrast to the form seen in infants and children, was not associated with mental retardation, peculiar faces or the syndrome of hypercalcemia. Diagnosis was confirmed by retrograde left heart catheterization and left ventriculography. Surgical correction was performed by the replacement of oval shaped Woven Dacron patch over the narrow segment of aorta under the cardiopulmonary bypass. Blood pressure was controlled sufficiently with some adjunct of Inderal postoperatively. The patient was discharged with much improvement.

  • Takayasu`s arteritis is one of chronic inflammatory disease characteristically involving the aorta and it`s major branches. We experienced two surgical cases of Takayasu`s arteritis associated with the stenosis of the descending thoracic aorta. One case was 15 year-old girl and she was admitted because of dyspnea on exertion for 12 months. Aortogram showed the stenosis of the descending thoracic aorta from just below left subclavian artery to the 9th thoracic vetebra. The other case was 10 year-old girl and she was admitted because of URI and hypertension. Aortogram showed narrowing of right innominate artery, but developed collateral circulation, and the stenosis of the descending thoracic aorta near the 9th thoracic vertebra. In each case, bypass graft from the ascending aorta to the abdominal aorta just above the inferior mesenteric artery was performed with satisfactory result.

  • This paper reports a case of type 1 posterior glottic stenosis in a 60-year-old woman that was misdiagnosed as bronchial asthma. The patient was intubated at another hospital after ingesting herbicide and extubated seven days later. Although her voice changed, she had not received treatment at that time. She visited a local internal medicine clinic when her condition deteriorated to the point of dyspnea, but several months of treatment for bronchial asthma failed to improve her symptoms. Upon admission to the author's hospital, a laryngoscopic examination revealed a type 1 posterior glottic stenosis, which was removed surgically using a CO2 laser.

  • Here, we present the case of a 2-month-old male infant with hyponatremic hypertensive syndrome resulting from stenosis of the right proximal and mid-renal arteries. The patient exhibited nephrotic-range proteinuria, low serum albumin, increased serum creatinine, and elevated renin and aldosterone levels. Doppler ultrasonography and computed tomography angiography revealed decreased vascular flow in the small right renal artery. Following a successful percutaneous balloon angioplasty, the patient experienced a decrease in blood pressure and normalization of serum electrolyte levels within a few days. However, it took 3 months for the proteinuria to resolve completely. This case is significant as it represents the first reported instance of a neonate presenting with clinical features resembling congenital nephrotic syndrome caused by renal artery stenosis that was successfully treated with percutaneous renal angioplasty.

  • 기도에 발생하는 결핵의 후유증으로 종종 원위부 기관이나 주 기관지에 미만성 협착이 발생한다. 기관지 협착이 주 기관지에만 존재할 경우 기관지 소매 절제술로 치료할 수 있는데, 협착의 길이가 2cm 이내일 경우 기관지 소매 절제술을 시행하기에 좋은 대상이 된다. 그러나 협착의 길이가 긴 경우에는 기관지 소매 절제술을 시행하기 어렵거나 또는 불가능할 수 있어 전폐젤제술 또는 기관지내시경적 치료를 시행하기도 한다. 확대 소매 폐엽절제술은 기관지 성형술을 이용하여 한 개 이상의 폐엽을 절제하는 수술 방법으로 주로 국소적으로 진행된 폐암에서 전폐절제술을 피하기 위하여 시행되었다. 저자들은 기도 결핵의 후유증으로 우측 주 기관지, 중간 기관지, 우중엽 기관지 및 우하엽 기관지에 심한 협착이 존재하는 환자에 대해 확대 소매 폐엽절제술을 시행하여 좋은 치료 결과를 보인 증례를 문헌고찰과 함께 보고한다.

  • Objectives : This study aims to evaluate currently available clinical evidence for the use of acupuncture in patients with lumbar spinal stenosis in the context of Republic of Korea. Methods : Five Korean databases were searched for all clinical studies employing acupuncture for patients with lumbar spinal stenosis. The exceptions were case reports and series involving less than 10 patients from their inception to September 2011. Only studies reported in Korean databases were searched. Results : Five retrospective audits among 22 initially identified studies were eligible for analysis in this review. There was no randomized controlled trial for this topic. The number of patients varied between 15 and 119 in each audit, and all the patients analyzed were inpatients. In all the included studies, acupuncture was conducted in combination with other concomitant treatments, including moxibustion, cupping, herbal remedies, acupoint injection, Chuna, and various physical therapies. All the included audits reported symptomatic and/or functional improvements compared to baseline. None of the included audits indicated whether any adverse events were reported. Conclusions : Current evidence for the use of acupuncture in patients with lumbar spinal stenosis in the context of South Korea is based solely on five retrospective audits that are very likely prone to a high risk of bias. Thus, further prospective and methodologically sound clinical trials to overcome this huge gap between clinical practice and the available evidence for the use of acupuncture in patients with lumbar spinal stenosis are needed.

  • 기관지 정맥류는 기관지 정맥압이 상승하는 승모판 협착증이나 폐정맥 폐쇄증에서 이차적으로 발생할 수 있다. 기관지 정맥류는 주로 좌측 주기관지에서 관찰되며, 드물지만 기관지 정맥류의 파열로 대량 객혈이 가능하고 사망할 수도 있다. 저자들은 중증 승모판 협착증 환자에서 동반된 기관지 정맥류를 기관지내시경에서 우연히 관찰하였고 승모판치환술 후 기관지 정맥류가 호전되어 이를 문헌고찰과 함께 보고하는 바이다.
