인공판막 재치환술 환자에서 CT를 이용한 심막유착의 평가

Abstract

PURPOSE: To evaluate the efficacy of computed tomography(CT) in detecting pericardial adhesion. MATERIALS ANDMETHODS: CT of 32 patients with 'redo-valve surgery' was retrospectively evaluated for the location and appearanceof their surgically confirmed pericardial adhesion. CT of 20 cases without cardiac or pericardial disease wasreviewed as normal control. RESULTS; Nodular increased density at the site of adhesion between the sternum and theright atrium(RA) or ascending aorta(n=10), retrosternal dirty fat(n=10), obliteration of the pericardialfat(n=28), cardiac contour change with or without nodular epicardial fat accumulation(n=10), diffuse pericardialthickening(n=14), and pericardial calcificataion(n=13) were considered to be important findings. We also noticedan additional findings of beak-like projection of RA appendage(n=13), but was considered less singnificant becausethey were also observed in 4 normal subjects. CONDLUSION: CT scan is an effective, simple, and noninvasive methodfor predicting percardial adhesion that may be occurred after redo-valve surgery.
