复杂先天性心脏病双向 Glenn 分流术后：3T MRI 评价肺血管形态和血流
The measurement of morphous and blood flow of pulmonary vessels for patients with complex congenital heart disease underwent bidirectional Glenn shunt on 3.0 Tesla MR system
摘要
Abstract
Objective To evaluate the relationship of pulmonary blood flow and parameters of pulmonary vessels growth for patients with bidirectional Glenn shunt (BGS) by using 3.0 Tesla MR system.Methods Twenty-two patients with BGS were performed with phase-contrast MR imaging ( PC-MRI ) sequence to measure the blood flow of great vessels of pulmonary circulation and systemic circulation ,and the quantity of pulmonary and systemic circulation(Qp and Qs) per minute were calculated by using Report Card software .The parameters of pulmonary vessels growth were performed by using contrast-enhanced MR imaging ( CE-MRI ) sequence .The parameters of blood flow of left and right pulmonary artery ( LPA and RPA ) , the relationship of pulmonary volume and the parameters of pulmonary vessels growth between different groups were analyzed .Results The Qp/Qs was found to be 0.599 ±0.111 for BGS patients ,and the group of pulmonary artery stenosis ( PS) was significantly larger than the group of pulmonary artery atresia ( PA) ( t=3.422 ,P=0.003 ) .The flow volume of RPA [ ( 56.1 ±10.9 )%] was significantly higher than that of LPA [ ( 43.9 ±10.9 )%] , while the regurgitation fraction of RPA was significantly lower than that of LPA ( t =-2.689 , P =0.014 ) .A positive relationship of the flow volume and the growth parameters of pulmonary arteries was found ( r =0.456-0.698 ) .The growth parameters and flow volume of pulmonary arteries of group PS were found significantly better than that of group PA (all P>0.05).Conclusions A good correlation of the flow volume obtained by PC-MRI and the growth parameters obtained by CE-MRI for pulmonary vessels are demonstrated , and the combined parameters of the two sides may be used to evaluate the morphous and function of pulmonary vessels .The group of PS favors the development of pulmonary vessels for BGS patients.关键词
