【摘要】Objective To evaluate the value of mulidetector-row computed tomography (MDCT) in diagnosis of persistent truncus arteriosus (PTA) . Methods
Contrast-enhanced
MDCT
scan
and
transthoracic
echocardiography(TTE) were simulaneously performed in 11 cases with suspected PTA. Among them, eight cases underwent measurement of pressure of pulmonaty artery by car-dioangiography(CAG) and operation. The results of MDCT were compared with that of TTE and surgery. Results In 11 cases with PTA diagnosed by MSCT,according to Van Praagh classification, there were type Al in 7 cases, type A2 in 2 cases, type A3 in one and type A 4 in one. Two cases accompanied with coronary anomalies with TTE,the qualitative diagnosis of PTA in night cases was made, the correct classification in five cases, but A cases not, and seven cases were showed with valvular regurgitation, 2 cases were misdiagnosis as pulmonaty atresia. 8 cases with type Al and A2 were diagnosed with serious pulmonary hypertension by CAG,and underwent surgery. Conclusion PTA can be definitively diagnosed by MDCT, TTE can show the valve dysfunction well, MDCT in combination with TTE can improve the diagnosis of PTA.%目的 探讨永存动脉干的多排螺旋CT诊断价
