The major causes of hemorrhagic pericardial effusion are malignancy and tuberculosis. However, it was unknown to the use of biochemical analysis of pericardial fluid and serum, for differentiation of malignancy from tuberculosis. To evaluate this, we investigated the biochemical analysis of pericardial fluid and serum in relation to the causes of pericardial tamponade. Subjects and Methods:46 patients who were admitted to Pusan National University Hospital from January 1, 1995, to April 30, 2002, and underwent both a pericardiocentesis and a pericardiostomy for the relif of cardiac tamponade, were included in this study. the pericardial fluid was routinely analyzed for the following:gross appearance, cell count, glucose, total protein (TP), lactate dehydrogenase (LDH), cytology, gram stain, cultures for bacteria and mycobacterium, pericardial fluid to serum ratios of total protein and lactate dehydrogenase, (p/s TP, p/s LDH, respectively). Results:Of the 46 patients who underwent both pericardiocentesis and pericardiostomy, for the relief of cardiac tamponade, 33 patients (71.7%) had hemorrhagic pericardial effusion. The common causes of hemorrhagic pericardial effusion were malignancy (51.5%) and tuberculosis (33.3%) but, those of nonhemorrhagic pericardial effusion were idiopathic (38.5%). Cell counts were higher in hemorrhagic than nonhemorrhagic group (p=0.029). Serum LDH (sldh) was higher in malignant than tuberculous group (p=0.001) but, serum total protein (stp) was higher in tuberculous group (p=0.004). Compared malignant group with tuberculosis group in patients with hemorrhagic pericardial effusion, p/s ratio of LDH and stp were higher in tuberculous group (p=0.029, p=0.017), but sldh was higher in malignant group (p=0.002). Conclusion:It is difficult to differentiate tuberculosis from malignancy only on the basis of the biochemical analysis of pericardial fluid in hemorrhagic pericardial effusion. However, the analysis of both pericardial fluid and serum may make it possible to evaluate the cause of pericardial effusion.

Meyers 등 1) 은적혈구수가 100,000/ mm 3 이상일때혈성심낭삼출물로분류하였지만혈성과비혈성심낭삼출물의원인에따른비교를하지않았다. Colombo 등 11) 과 Zayas 등 12) 은혈성심낭삼출물의가장많은원인은악성종양이라고발표했으며, Colombo 등 11) 은장액성심낭삼출물의가장많은원인은원인불명이며, 예후는양성이라고하였다. 본연구에서혈성심낭삼출물의주된원인은악성종양 (51.5%) 과결핵 (33.3%) 이었다. 비혈성심낭삼출물의주된원인은원인불명 (38.5%) 이었다. 본연구결 과에서도비혈성심낭삼출물군에비해혈성심낭삼출물군에서악성종양과결핵이많았다. 혈성심낭삼출물이비혈성심낭삼출물보다심낭삼출물내세포수 (p=0.029) 가많았다. 악성종양과결핵의두군을비교했을때 sldh 는악성종양군에서높았고 (p= 0.001), stp는결핵군에서높았다 (p=0.004). 혈성심낭삼출물군에서원인이악성종양과결핵인두군을비교했을때악성종양군이 sldh, stp 가높았고, p/s LDH 는낮았다 (p=0.029). 결론적으로혈성심낭삼출물인경우심낭삼출물의생화학적분석만으로는악성종양과결핵을감별하기힘들고심낭삼출물과혈청을같이생화학적검사를하여비교분석함으로써감별이가능할것으로사료된다. 요약 배경및목적 : 심초음파가기본적인진단수단으로발전한이후심낭삼출물은흔한임상적소견이되었다. 혈성인경우에는질환의특징과잠재적인출혈의가능성및심각성때문에임상적으로중요하다. 국외발표에서혈성심낭삼출물의주된원인은악성종양과결핵으로알려져있다. 심낭압전으로진단된환자에서혈성과비혈성심낭삼출물의원인과생화학적분석및차이, 그리고원인이악성종양과결핵인경우, 심낭삼출물과혈청의생화학적분석및차이에대해알아보고자하였다. 방법 : 1995년 1월부터 2002년 4월까지부산대학교병원에서심낭압전으로진단되어심낭절제술과심낭천자를시술받은 46명을대상으로육안소견, 세포수, 포도당수치, 총단백질수치 (TP), 유산탈수소효소 (lactate dehydrogenase, LDH), 세포학적검사 (cytology), 세균과결핵도말과배양, 그람염색, 심낭삼출물 / 혈청단백질비율 (p/s TP), 심낭삼출물 / 혈청 LDH 비율 (p/s LDH) 을시행하고분석하였다. 결과 : 심낭압전으로심낭절제술또는심낭천자를시술받은 46명의환자에서 33명 (71.7%) 이혈성심낭삼출물이었고, 그원인은악성종양 (51.5%) 과결핵 (33.3%) 이가장많았고, 비혈성심낭삼출물은원인불명 (38.5%) 이많았다. 심낭삼출물의세포수는비혈 231

6 성심낭삼출물보다혈성심낭삼출물에서많았다 (p= 0.029). 악성종양과결핵의두군을비교했을때악성종양군에서 sldh 가높았고 (p=0.001), 결핵군에서혈청단백질 (p=0.004) 이높았다. 혈성심낭삼출물군에서주된원인인악성종양과결핵인두군을비교했을때, 악성종양군에서 sldh 가높았고 (p=0.002), stp와 p/s LDH는결핵군에서높았다 (p=0.017, p= 0.029). 결론 : 혈성심낭삼출물인경우심낭삼출물의생화학적분석만으로는악성종양과결핵을감별하기힘들고심낭삼출물과혈청을같이생화학적검사를하여비교분석함으로써감별이가능할것으로사료된다. 중심단어 : 심낭삼출 ; 혈청화학분석. 감사문본논문을작성하는데있어서부족한부분에대한많은지도와도움을주신교수님께감사드립니다.
