이면적 심초음파도를 이용한 Large Pericardial Effusion의 정량적계측

Abstract

Background : The accurate information about the volume of pericardial effusion can assist in clinical decision and has important prognostic. In addition, accurate quantification of serial change in effusion volume is necessary in assessing pericardial disease and marking a decision of immediate drainage. This study was performed to evaluate the efficacy of 2-D echocardiographic quantification of pericardial effusion. Method : The study populations are 22 patients with large pericardial effusion whose volume of effusion is confirmed by paracentesis of surgical drainage. Through the echocardiographic review, the volume of pericardial sac and heart was calculated by method of D’cruz and then, the effusion volume was derived as the difference of two volumes. Each echocardiographically calculated volume of pericardial effusion was compared with the measured volume drained percutaneously of surgically. Result : The volume of pericardial effusion calculated echocafdiographically was excellently correlated with the drained volume(r=0.90, p<0.01). The echo-free space was well correlated with the volume of pericardial effusion in the anterior aspect of the heart(r=0.71, p<0.01), but not in the posterior aspect. Conclusion : 2-D echocardiographic Quantification of pericardial effusio is simple and reliable method, and its clinical efficacy may be great.
