【目的】探讨房间隔缺损的X线、B超及MRI表现特征,为临床医生提供综合可靠的影像资料。【方法】搜集我院收治的184例房间隔缺损患者的X线、B超、MRI影像资料,结合文献对其影像学表现做回顾性比较分析。【结果】术前X线、B超及MRI检查对本组184例房缺患者的阳性诊断率各有不同,其中全心增大为6.52%、9.24%与7.02%,单纯右房增大为18.48%、19.57%与15.79%,右房、右室增大为59.78%、53.26%与49.12%,右房、左房增大为6.52%、4.89%与7.02%。术后随访显示,ASD中继发孔型占87.5%,静脉窦型占5.98%,冠状窦型占4.89%,原发孔型占1.63%;而合并畸形中三尖瓣关闭不全占23.91%,动脉导管未闭占6.52%,左上腔静脉占2.72%,二尖瓣关闭不全占1.63%,肺动脉狭窄占5.98%。【结论】X线平片主要用于观察ASD的心脏外形大小形态和手术前后对比观察肺血管改变;彩色超声心动图能够准确的探明缺损的部位、大小、分流,肺动脉压力及合并畸形;MRI不仅能观察ASD缺损部位大小和各房室大小,而且还可观察肺血情况。
【Objective】 To explore the X-ray, B-ultrasound and MRI features of atrial septal defects and provide clinicians comprehensive and reliable imaging data. 【Methods】 A total of 184 cases of atrial septal defects treated by X-ray, B-mode ultrasound and MRI were collected and analyzed retrospectively. 【Results】 The positive diagnostic rates of preoperative X-ray, B-ultrasound and MRI in 184 patients with atrial septal defects were all different, among them the total heart rate was 6.52%, 9.24% and 7.02%, and the right atrium was only 18.48 %, 19.57% and 15.79% respectively. The right atrium and right ventricle increased to 59.78%, 53.26% and 49.12%. The right atrium and left atrium increased to 6.52%, 4.89% and 7.02% respectively. Postoperative follow-up showed that the ASD relay hole accounted for 87.5%, sinus accounted for 5.98%, coronary sinus accounted for 4.89%, primary hole accounted for 1.63%; combined deformity in tricuspid regurgitation accounted for 23.91% Patent ductus arteriosus accounted for 6.52%, left superior vena cava accounted for 2.72%, mitral regurgitation accounted for 1.63%, pulmonary stenosis accounted for 5.98%. 【Conclusion】 The X-ray film is mainly used to observe the size and shape of the heart shape of ASD and to compare the pulmonary vascular changes before and after surgery. The color echocardiography can accurately identify the location, size, shunt, pulmonary artery pressure and combined deformity. ASD can not only observe the size of the size of the defect and the size of the atrioventricular, but also to observe the situation of pulmonary blood.
