Double lumen ( true and false lumen) of the aorta and intimal flap are direct signs for diagnostic significance in AD studied with SE-MRI. SE-MRI诊断AD的直接征象是内膜片和主动脉双腔(真、假腔),42例AD中除1例外均显示,诊断率为97.6%,横轴位最适于上述征象的观察。
Methods SE sequence and cine MRI were performed in 21 cases of congenital heart disease, including 14 cases of tetralogy of Fallot, 2 of atrial septal defect, 2 of double outlet of right ventricle, 1 of single ventricle, and 2 of coarctation aorta. 方法先天性心脏病患者21例,其中Fallot四联症14例,房间隔缺损2例,右室双出口2例,单心室1例,主动脉缩窄2例。
Results Of 17 cases, type ⅰ was seen in 8, type ⅱ in 6 and type ⅲ in 3. Both SE sequence and cine MRI clearly displayed the double lumen of aorta and the intimal flap. 结果17例中,Ⅰ型8例,Ⅱ型6例,Ⅲ型3例。SE序列和电影MRI均清楚地显示了主动脉双腔、内膜片。
Conclusion Double irrigation digestive method via abdominal aorta and umbilical vein should first be selected in isolating HFH. 结论人胎肝细胞的分离应首选经腹主动脉及脐静脉双灌流消化法。
Modified Rastelli procedure for double outlet right ventricle with left-malposition of the aorta 改良Rastelli手术治疗右心室双出口合并左前位主动脉
Double purse-string suture was done to cannulate the ascending aorta and specially designed membrane oxygenation was used to set up bloodless, small priming volume CPB. 缝主动脉双荷包建立升主动脉插管,利用特制膜肺,建立无血预充的小预充量体外循环。
