Although TACE is relatively safe, acute respiratory distress syndrome associated with pulmonary lipiodol embolism is a rare and potentially fatal complication. We report a rare case of acute respiratory distress syndrome after TACE for inoperable HCC. A 75-year-old man, with huge HCC in right lobe, was treated by TACE for the first time. Seven hours after uneventful TACE procedure, he felt dyspneic and his oxygen saturation recorded by pulse oximetry (SpO 2) fell to 80% despite of applying non-rebreathing mask. He underwent mechanical ventilation with a protective ventilatory strategy. We experienced a case of acute respiratory distress syndrome after TACE for HCC.

이에저자등은 75세남자환자에서간세포암치료를위해시행한간동맥화학색전술후약 7시간후에발생한급성호흡곤란증후군 1 예를경험하였기에문헌과함께보고하는바이다. 증례 75세남자가내원 3주전부터피로감이있어타병원에서혈액검사시행후간기능이상소견을보여본원으로전원되었다. 과거력상한센병외특이질환은없었으며사회력상한번에소주 1병씩한달에 2 3번마시는음주력및 15갑년의흡연력이있었다.

2 Jo YW, et al: ARDS after Transcatheter Arterial Chemoembolization 경우간동맥화학색전술도중리피오돌 (lipiodol) 투여로인한지질폐렴이원인인것으로알려져있다 [7]. 리피오돌로인한폐색전증은 1990년 Samejima 등 [8] 에의해처음보고되었으며, 국내에서는 1995년 Cho 등 [9] 에의해처음보고되었다. 이러한리피오돌폐색전증은대부분보존적치료로치유되는것으로알려져있고, 간동맥화학색전술후리피오돌로인한폐색전증과관련된급성호흡곤란증후군은매우드물게발생하는것으로알려져있다. 이에저자등은 75세남자환자에서간세포암치료를위해시행한간동맥화학색전술후약 7시간후에발생한급성호흡곤란증후군 1 예를경험하였기에문헌과함께보고하는바이다. 증례 75세남자가내원 3주전부터피로감이있어타병원에서혈액검사시행후간기능이상소견을보여본원으로전원되었다. 과거력상한센병외특이질환은없었으며사회력상한번에소주 1병씩한달에 2 3번마시는음주력및 15갑년의흡연력이있었다. 활력징후는안정적이었으며이학적검사에서공막의황달소견이나결막의빈혈소견등은없었으며복부진찰에서간비대소견이관찰되었다. 말초혈액검사에서혈색소 12.2 g/dl, 헤마토크리트 36%, 백혈구 7,240/mm 3, 혈소판 237,000/mm 3 였고, 혈청학적검사에서는총단백 6.8 g/dl, 알부민 3.9 g/dl, 총콜레스테롤 192 mg/dl, AST 47 IU/L, ALT 69 IU/L, Alkaline phospatase 103 IU/L, 총빌리루빈 0.85 mg/dl, 직접빌리루빈 0.12 mg/dl이었다. B형간염표지인자는 HBsAg( ), HBsAb( ) 이었으며 C형간염항체는음성이었다. 알파태아단백은 ng/ml, 프로트롬빈시간은 13.2초 (98%) 였다. 흉부X-선촬영에서양폐야에망상형음영 (reticular opacity) 과벌집모양 (honeycombing) 변화소견을보여특발성폐섬유증이의심되었다. 복부전산화단층촬영에서간우엽에 cm 크기의경계가명확한저음영의종괴가관찰되었다 (Fig. 1). 임상적소견및영상의학적검사에서간세포암이진단되었으나수술이불가능하여간동맥화학색전술을시행하였다. 간동맥혈관조영술에서간우엽에우측간동맥과위십이지장동맥에서공급받고있는거대종양병변이관찰되었다. 선별된종양간동맥으로 adriamycin 50 mg과리피오돌 30 ml를섞어서서히주입하였으며이어젤폼입자를주입하여간동맥화학색전술을시행하였다 (Fig. 2). 간동맥화학색전술 7시간경과후환자는갑작스런호흡곤란을호소하였다. 활력징후는혈압 130/80 mmhg, 맥박 116회 / 분, 호흡수 36회 / 분, 산소포화도는 71% 까지감소하여산소마스크를통해산소 10 L/ 분적용하였다. 동맥혈가스검사에서 PaO 2 58%, 산소포화도 91.6% 였으며흉부 X-선촬영에서양측폐에전반적인간유리음영 (ground glass opacity) 이증가하였다 (Fig. 3). 이학적검사에서양측폐에심한수포음이청진되었다. 심초음파및 D-dimer는정상소견이었다. 간동맥 Fig. 1.

Chest computed tomography shows multifocal crazy paving pattern and interlobular septal thickening in both lung, and honeycombing in both lower lobes. 화학색전술시행 1일경과후환자의호흡부전이진행하여기관내삽관및기계호흡을적용하였다. 환자의동맥혈가스검사에서 PaO 2/FiO 2 가 200 이하였으며, 흉부전산화단층촬영에서소엽간중격이두꺼워져있고소엽중심에는간유리음영이보이는불규칙한돌조각보도모양 (crazy paving pattern) 을보여급성호흡부전증후군으로진단할수있었으며, 리이오돌이나지방이관찰되지는않았다 (Fig. 4). Methylprednisolone 60 mg을 4시간간격으로정맥주사하면서경험적항생제와이뇨제투여및호기말양압 (positiveend-expiratory pressure) 을이용한기계호흡치료를시행하였다. 기계호흡치료 2일째부터 PaO 2/FiO 2 가 250 이상으로호전되었으며흉부 X-선 간동맥화학색전술은종양의크기가크고, 상당히진행된간세포암에서시행할수있는치료법으로간동맥의폐색을유발하여간종양의허헐성괴사를초래한다. 이러한간동맥화학색전술과관련하여증상을동반하는폐합병증이발생하는경우는매우드문것으로알려져있다 [10]. 연구에따르면간동맥화학색전술을시행받은 23% 의환자에서호흡기증상을동반하지않는관류폐스캔이상소견이관찰되었고 % 의환자에서는폐색전증의증상을동반하였다 [7,11]. 간세포암환자에서발생한폐색전증은종양자체에의한폐색전증도보고되어있으나 [12,13] 대부분은간동맥화학색전술도중과량의리피오돌투여로인한폐색전증이주된원인으로알려져있다. 간동맥화학색전술후발생한폐지질색전증은 1990년 Samejima 등 [8] 에의해처음보고되었다. 75세의남자환자가간세포암으로리피오돌 8 ml과 adriamycin 40 mg 혼합물로간동맥화학색전술시행후 30분후에폐부종이나타났으며저자들은동-정맥루 64 THE EWHA MEDICAL JOURNAL

4 Jo YW, et al: ARDS after Transcatheter Arterial Chemoembolization 를통한과량의 adriamycin이폐동맥으로의유입이원인이라고생각했다 [8]. 이후 1995년 Chung 등 [7] 에의해간동맥화학색전술이후생기는폐합병증에대한연구가이루어졌는데, 간동맥화학색전술을받은 336명의환자중 6명에게서폐동맥지질색전증이보고되었고, 모두적어도 20 ml 이상의리피오돌이주입된경우였다. 이들의증상은주로기침, 객혈, 호흡곤란이었으며주로시술이후 2 5일사이에나타났다. 단순흉부 X선촬영에서는양폐의미만성침윤소견을보였다. 이연구에따르면저자들은폐동맥지질색전증의원인을 20 ml 이상의리피오돌주입으로결론지었다. 간동맥화학색전술이후생기는폐동맥지질색전증의기전은아직불명확하나간동맥으로의리피오돌의주입후동-정맥루를통하거나정상적인간혈류를통해서리피오돌이폐로들어가서미세색전의분해과정에서생기는고농도의 unbound free fatty acids가폐모세혈관의누출과폐부종을초래한다는것이라는가설이널리알려져있다 [7]. 간동맥화학색전술이후생기는폐동맥지질색전증의위험인자는리피오돌양이외에도리피오돌주입방법 [7,14], 리피오돌의간종양내의잔류정도 [7], 동-정맥루여부 [7,14], 하부가로막동맥 (inferior phrenic artery) 색전술 [14] 등이다. 이중가장중요한요소가투여한리피오돌의양이다 [7]. 간동맥화학색전술후생기는폐동맥지질색전증의예방법은리피오돌의양을 ml 이상투여하지않도록하며, 초선택색전술 (superselection embolization) 을시행하고 [7], 동정맥루가관찰될경우동-정맥루를가진간정맥분지를풍선을통해일시적으로막아동정맥루의정도를줄이는것이다 [15]. 그밖에 polyvinylalcohol, gelatine sponges, coils 등을통한동정맥루색전술이대안으로제시되고있다 [16,17]. 폐동맥지질색전증의명확한치료법은아직없다 [18]. 산소치료, 고용량 methylprednisolone, 헤파린, 호기말양압등의치료가효과가있다는보고가있으나입증되지는않았다 [19]. 본증례에서는 30 ml의리피오돌이투여되었고, 특발성간질성폐렴이동반되어폐동맥지질색전증에더취약했을것으로생각된다. 결론적으로폐동맥지질색전증은간동맥화학색전술의심각한합병증이며위험인자로는리피오돌의투입량, 동-정맥루의유무, 하부가로막동맥색전술등이다. 리피오돌투여양을줄이고동-정맥루의정도를줄여주는것이예방방법이며산소치료, 고용량스테로이드, 헤파린, 호기말양 압등이치료법이될수있다. 참고문헌 1.
