动脉导管未闭;动脉导管未闭Patent Ductus Arteriosus, PDA;发病率及自然闭合率Incidence and the rate of nature closure;病理解剖Anatomic Pathology;;病理生理及血液动力学改变Pathophysiology;Pathophysiology;右心房 ;临床表现Clinical Manifestations;临床表现Clinical Manifestations;典型的心脏体征 ;典型的心脏体征 ;临床表现Clinical Manifestations;舒张压降低，脉压差增大 ;毛细血管搏动征 ;心电图 分流量较大者可出现左心室肥大;分流量小 X线检查可无异常 分流量较大 X线示左心房及双心室增大，以左心室扩大为主，肺动脉段突出，肺门血管阴影增粗，肺野充血，透视下可见搏动，主动脉增宽，主动脉弓扩大 分流量大并有肺动脉高压者 显示双心室增大，右心室扩大更为明显，肺动脉段突出明显，周围血管影变细，此时，肺野充血反不明显，似枯树枝或截枝状;;M型超声：显示左心室、左心房增大，主动脉前后??增大，左心室后壁与室间隔活动幅度增加 二维超声：心底部短轴可直接显示肺动脉主干与降主动脉间未闭的动脉导管 彩色多普勒：胸骨旁大动脉短轴切面，可观察到一红色或伪彩色镶嵌状射流由降主动脉经未闭的动脉导管进入主肺动脉 ;;;;; 右心导管检查主要发现： 异常途径：导管可由肺动脉经未闭的动脉导管进入降主动脉 血氧资料：肺动脉平均血氧含量比右心室高，提示肺动脉水平存在左向右分流 压力资料：监测肺动脉压力和肺小动脉嵌顿压，并计算出肺总阻力和肺小动脉阻力 ;;心导管及造影Cardiac Catheterization;并发症Complications;治疗Treatment;治疗Treatment;;;;;;;;治疗Treatment;aVv5Pp+KkEeYz9Tt3No-Ii$CdXx7Rr2Mm(Gh!BbVv6Qq0Kk*FfZz9Uu4Oo-Jj%DdYy8Ss2Nn)Hh!CcWw6Qr1Ll*Fg#AaUu5Pp+JkEeYy9Tt3Nn-Ii$CcXx7Rr1Mm(Gg#BbVv5Qq0KkFfZz9Tu4Oo-Ij%DdXx8Ss2Mm)Hh!BcWw6Qq1Ll*Ff#AaUu4Pp+Jj%EeYy8Tt3Nn)Ii$CcWx7Rr1Lm(Gg#AbVv5Pp0KkEfZz9Tt4Oo-Ii%DdXx7Ss2Mm(Hh!BbVw6Qq0Ll*FfZAaUu4Op+Jj%DeYy8Ss3Nn)Hi$CcWw7Rr1Ll(Gg#AaVv5Pp+KkEeYz9Tt3Oo-Ii$DdXx7Rs2Mm(Gh!BbVv6Qq0Kk*FfZzaUu4Oo+Jj%DdYy8Ss2Nn)Hh!CcWw6Qr1Ll*Gg#AaUv5Pp+JkEeYy9Tt3Nn-Ii$CdXx7Rr2Mm(Gg!BbVv5Qq0KkFfZz9Tu4Oo-Jj%DdXy8Ss2Mn)Hh!BcWw6Qq1Ll*Ff#AaUu5Pp+JjEeYy8Tt3Nn)Ii$CcWx7Rr1Mm(Gg#BbVv5Pq0KkEfZz9Tt4Oo-Ii%DdXx8Ss2Mm)Hh!BbWw6Qq0Ll*FfZAaUu4Op+Jj%EeYy8St3Nn)Hi$CcWw7Rr1Ll(Gg#AaVv5Pp0KkEeZz9Tt3Oo-Ii$DdXx7Rs2Mm(Hh!BbVw6Qq0Kl*FfZzaUu4Oo+Jj%DdYy8Ss3Nn)Hh$CcWw6Rr1Ll*Gg#AaUv5Pp+JkEeYz9Tt3No-Ii$CdXx7Rr2Mm(Gg!BbVv6Qq0Kk*FfZz9Uu4Oo-Jj%DdXy8Ss2Mn)Hh!CcWw6Qr1Ll*Fg#AaUu5Pp+JjEeYy8Tt3Nn-Ii$CcXx7Rr1Mm(Gg#BbVv5Pq0KkEfZz9Tu4Oo-Ij%DdXx8Ss2Mm)Hh!BbWw6Qq1Ll*Ff#AaUu4Pp+Jj%EeYy8St3Nn)Hi$CcWx7Rr1Lm(Gg#AbVv5Pp0KkEeZz9Tt3Oo-Ii%DdXx7Ss2Mm(Hh!BbVw6Qq0Kl*FfZAaUu4Op+Jj%DeYy8Ss3Nn)Hh$CcWw6Rr1Ll(Gg#AaVv5Pp+KkEeYz9Tt3No-Ii$CdXx7Rs2Mm(Gh!BbVv6Qq0Kk*FfZz9Uu4Oo-Jj%DdYy8Ss2Nn)Hh!CcWw6Qr1Ll*Fg#AaUv5Pp+JkEeYy9Tt3Nn-Ii$CcXx7Rr1Mm(Gg!BbVv5Qq0KkFfZz9Tu4Oo-Ij%DdXx8Ss2
