후두 및 기관협착증은 선천적으로 발생하기도 하지만 대부분이 후천적으로 발생한다. 후천적인 원인으로는 외부로부터의 외상에 의하기도 하지만 대개가 기관내 삽관 후유증으로 발생하는 것으로 알려져 있다. 기관내 삽관에 의한 기도 점막의 손상은 대부분 가역적이기는 하지만 영구적으로 협착을 초래하는 경우, 그 치료에 있어서 많은 노력이 필요할 뿐만 아니라 치료 자체가 매우 까다롭고 실패 할 수도 있다. 따라서 후두 및 기관협착증의 원인을 정확히 이해하고 예방하는 것이 매우 중요하다. 이러한 관점에서 후두 및 기관협착증의 선천적, 후천적 원인들에 대해서 검토하여 보았다. 특히 기도 내 삽관에 따른 협착증이 가장 많은 빈도를 차지하는 만큼, 이의 병태생리와 발생에 관여하는 여러 인자들에 대해서 중점적으로 문헌 고찰하였다.

Tracheal stenosis induced from the various causes has still remained as a serious problem in the otolaryngologic field. There has been used the numerous methods in the treatment of the tracheal stenosis and the each case has required the therapeutic modality. Now, we report two cases of tracheal stenosis ; one case had been used the silicone T - tube in the tracheal stenosis after tracheostomy in 6 year - old child and the other one had been used the silicone tube stent with oral mucosa graft in the treatment of the tracheal narrowing due to inflammatory mass in 19 year - old male patient.

Supravalvular aortic stenosis is an uncommon, congenital narrowing of the ascending aorta which originates just distal to the level of the ostium of the coronary artery. We conducted a successful surgical treatment in a 39 year- old female patient with a congenital supravalvular aortic stenosis and aortic regurgitation who did not show signs of William's syndrome. After we performed an inverted Y-shaped aortotomy toward the noncoronary sinus and right coronary sinus, pantaloon shaped prosthetic patch(Vascutek, Ino, USA) was used to repair the narrowing sinotubular junction. The aortic valve was replaced concommittently using Sorin Bicarbon 19mm. Her postoperative course was uneventful. The patient discharged at 9th postoperative day in good health.

최근 교통사고의 증가, 심폐술의 보편화 및 보조호흡을 필요로 하는 환자의 증가에 따라 경구적 혹은 기관절개술을 통해 기관내 삽관을 장기간 유치하는 경우가 많아져서 이에 따른 합병증으로 기관협착증의 빈도가 높아지게 되었다. 기관내 삽관후 기관협착증을 초래하는데에는 관의 외경, 삽관시 외상, 삽관유치기간, 기계적 보조호흡시 관의 이동, cuff 의 압력 등의 요인이 작용한다. 이러한 요인에 의해 기관내 삽관을 장기간 유치시 기관점막에 대한 지속적인 압박으로 점막하부의 압박괴사 및 혈관의 폐쇄로 인해 기관연골의 무혈성 괴사를 초래하여 환상의 기관협착이 병발하게 된다. 기관협착증에 대한 치료방법으로서는 여러 가지가 있으나 환상의 기관협착증인 경우는 협착부위의 절제 및 단단문합술을 시행하고 절제부위가 광범위한 경우는 release technique 을 이용하여 문합부위의 장력을 줄여주는 것이 효과적인 치료방법으로 알려져 있다. 저자들은 최근 기관내 삽관후에 병발한 환상기관협착증 3례(다발성 골절 1례, 기관지 천식 1례, 약물중독 1례)에 대해 기관절제 및 단단문합술을 경험하였기에 보고하고자 한다.

A 2-year-old female mixed dog(weighing 4.3 kg) was referred to the Veterinary Teaching Hospital, Kangwon National University, with primary complaints of exercise intolerance, nocturnal coughing and heart murmur. Diagnostic studies revealed bi-lateral holosystolic murmurs on phonocardiogram, over-riding aorta, pulmonic stenosis, ventricular septal defect, atrial septal defect, biventricular hypertrophy, and subaortic stenosis in diagnostic imaging studies. Based on the diagnostic findings, pentalogy of Fallot(POF) with subaortic stenosis(SAS) was tentatively diagnosed. This is the first case report of POF complicated with SAS in a dog in Korea.

In the patient who has intradural mass associated with spinal stenosis, if the operation for spinal stenosis is performed alone, the symptom may remain. We report with literature review that we achieved the successful outcome after simultaneous decompression of spinal stenosis and space occupying mass removal in the case of intradural and extradural compression. A 71-year-old female patient suffering from low back pain and radiating pain of both lower extremities admitted. In magnetic resonance imaging, spinal stenosis on L4-5 and spondylolisthesis on L5-S1 compressed dural sac and intradural space occupying mass on L4 level compressed. By posterior approach, decompression and interbody fusion were carried out. Then mass was removed with median durotomy. Pathologic diagnosis was schwannoma and the symptom was improved remarkably.

The conventional surgical treatment of isolated critical stenosis of the left main coronary artery restores a less physiologic perfusion of the myocardium, leads to occlusion of the left coronary ostium, and consumes an appreciable length of bypass material. From June 1994 to February 1996, eleven patients, three male and eight female, underwent patch angioplasty and additional bypass graft to left anterior descending artery (10 internal mammary artery, 1 saphenous vein) in isolated critical left main coronary artery stenosis. Their ages ranged from 34 to 62 years, mean 44 years. All had 60% to 90% stenosis of the left main coronary artery and Class III angina. The angiogram showed nine osteal lesion and three main stem stenosis. The operation was performed with conventional cardiopulmonary bypass and cold blood cardioplegia. We approached anteriorly and used bovine pericardium as onlay patch in all patients. There were one leg wound dehiscence, but no operative deaths and infarctions. All patients are free of symptoms after a mean follow-up of 15.5 months. Angiographic restudy at an average 14.4 months was obtained in five patients and showed widely patent left main coronary artery with excellent runoff. But additional graft to left anterior descending coronary artery were stenosed in two patients and showed diminutive flow in others. Our preliminary results suggest that angioplasty of the left main coronary artery can be carried out with low operative risks. But additional bypass graft to left anterior descending coronary artery may be unnecessary. The technique appears to be a promising alternative to conventional coronary artery bypass grafting in isolated left main coronary artery stenosis.

The incidence of degenerative valve disease also increasing with the increasing life expectancy of the elderly population. Rheumatic valve disease is decreasing gradually and the incidence of calcified degenerative aortic stenosis (AS) is growing. Echocardiography is a very important tool for evaluating the prognosis and treatment method as well as the time of operation and diagnosis of heart valve disease. When evaluating valvular heart disease, 2-dimensional echocardiography, which observes all heart valves in detail, should take precedence. Understanding the clinical findings of degenerative valve disease and performing precise echocardiography are extremely important. In addition, an assessment of the severity of aortic stenosis is necessary to determine the surgical indications. An assessment of the severity by echocardiography was explained with three cases of degenerative aortic stenosis. To perform echocardiography accurately, it is necessary to understand degenerative valve disease and its clinical findings accurately.

Subvalvular aortic stenosis developed after patch closure of perimembranous'VSD is rarely reported. A 18-month-old, 8 kg child with this complication after VSD closure 8 months ago in other hospital has been treated medically and was admitted to this hospital because of severe cardiomegaly and sign of heart failure. Cardiac catheterization revealed 55 mmHg of pressure gradient between aorta and LV cavity. We report one successful redo case of surgically relieved subvalvular aortic stenosis in a child after patch closure of perimembranous VSD.

후두 및 기관지 협착증은 대개가 기도확보를 목적으로 후두 및 기관내에 삽관을 시행하였을 때 삽관튜브에 부착된 cuff내에 압력이 높게 되면 점막에 혈류장애가 초래되고 궤양등의 점막손상이 뒤따르며 여기에 2차감염이 초래되어 육아종과 반흔이 생기면서 결국은 협착이 초래되는 것으로 알려져 있다. 이와 같이 손상된 후두및 기관의 점막에 산도가 강하고 소화효소가 함유된 위액이 역류되어 접촉될 경우 협착이 더욱 조장되리라고 가정할 수 있다. 따라서 위액이 과연 후두 및 기관지 협착증에 관여 한 것인지를 실험적으로 규명해 보고자 하였다. 실험동물은 가토를 대상으로 하여 Urethan마취를 시행하고, 삽관한 다음 합성위액 pH 1.5, 3, 5 짜리 용액을 기관 내에 1시간정도 관류시킨 다음 후두 및 기관을 적출하여 점막상태의 변화를 현미경으로 관찰하였다. 그 결과 산도가 강하고 펩신이 첨가된 합성위액으로 관류한 군에서는 성모의 파괴점막의 궤양, 부종과 염증소견 등이 심하게 관찰되었다. 그러나 산도가 약할수록, 그리고 펩신이 첨가되지 않은 합성위액으로 관류한 군에서는 섬모 및 점막의 손상이나 염증 및 부종등의 소견이 경미하게 관찰되었다. 이러한 결과로 미루어 강한 산도의 위액이 후두 및 기관으로 역류될 경우 협착증의 발생에 깊이 관여하리라고 추측되었다.
