초록

배경: 하행 괴사성 종격동염은 문헌에 따라 25%에서 40%의 사망률을 보이는 중증 질환이다. 대개의 원인은 치원성 및 구인두의 감염의 합병증으로 발병된다. 이에 된 교실에서는 지난 4년간 하행 괴사성 종격동염으로 외과적 치료를 받은 환자를 대상으로 후향적 조사를 하여 결과를 보고하고자 한다. 대상 및 방법: 1977년부터 2000년가지 하행 괴사성 종격동염으로 진단된 7례를 대상으로 하였다. 초기 구인두 감염이 종격동염으로 진행된 경우가 47례(57%), 치원성 감염이 3례(43%)이었다. 모든 경우에 괴사조직 제거 및 배농술을 위해 응급경부절개술, 개흉술 및 흉골절개술을 시행하였다. 결과: 평균 재원일은 42일이었고, 2례가 사망하여 사망률은 28.6%이었다. 재발된 농흉 2례와 심낭 압전증 1례는 재수술을 시행하였다. 사망 원인은 재수술후 12일째 대혈관 침식, 신부전 및 호흡부전으로 사망하였다. 재수술을 받지 않은 1례에서 수술후 10일째 기관지-식도루에 의한 질식으로 사망하였다. 결론: 하행 괴사성 종격동염의 사망률을 줄이기 위해서는 조기 진단과 신속한 경흉부 컴퓨터단층촬영 및 적극적인 외자적 치료가 필요하며, 세심한 수술 후 관리가 요구된다 하겠다.

Background: Descending necrotizing mediastinitis(DNM) is a serious complication originating in odontogenic or oropharyngeal infection with previously reported mortality rates of 25% to 40%. We retrospectively reviewed the 4 years of our surgical drainage and debridement in DNM. Material and Method: We studied 7 cases diagnosed as DNM from 1997 through 2000. Primary oropharyngeal infection lead to DNM in four cases(57%) and odontogenic abscess in three cases(43%). All patients were received emergent cervicotomy and thoracotomy or sternotomy for debridement of necrotic tissue and mediastinal or pleural drainage. Result: Five cases were evolved well and were discharged after a mean of 42 days. Two patients(28.6%) died. Three patients required reoperation due to local surgical complication; empyema(two) and impending cardiac tamponade. One of these patients died on 12 post-reoperative day due to great vessel erosion, renal and respiratory insufficiency. The other patient died of broncho- esophageal fistula and asphyxia on 10 postoperative day without reoperation. Conclusion: On the basis of experience accrued in treating these patients, early diagnosis by cervicothoracic computed tomographic scan of neck and thorax aids in rapid indication of a surgical approach of DNM. We emphasize that performing early surgical drainage and debridement of necrotic tissues with intensive postoperative care can significantly reduce the mortality rate.
