Abstract:
Objective:To explore value of 256-slice spiral CT pulmonary artery angiography (CTPA)evaluating right heart function in patients with acute pulmonary embolism (APE).Methods:According to death risk assessment of APE patients, a total of 67 APE patients were divided into high risk APE group (n=41)and non-high risk APE group (n=35).CTPA was used to analyze and compare CTPA obstructive index and right heart function indexes between two groups.Correlations among CTPA obstructive index and right heart function indexes were also analyzed.Results:Compared with non-high risk APE group,there were significant rise in CTPA constructive index [8.58% vs.24.69%],percentages of straight or left protruded ventricular septum (31.46% vs.73.17%)and bronchial artery dilation (5.71% vs.24.69%);Except the supe- rior vena cava diameter,the rest right heart function parameters had difference significance in two groups,P<0.05 or<0.01. Spearman correlation analysis indicated that CTPA obstructive index was significant positively correlated with right ventricular maximal short axis (RVMSA),RV:LV,diameters of main pulmonary artery,superior vena cava and azygos (r=0.684~0.954),and significant inversely correlated with LVMSA (r=-0.786),P<0.01 all.ROC curve analysis indicated that AUCs of CTPA RV:LV (0.949)was the biggest diagnosing APE severity.Conclusion:Right heart func- tion indexes measured by multi-detector CT are accurate and practical indexes evaluating APE severity,and it possesses im- portant significance.
