论述几种常见的先天性心脏病X线平片的主要征象。临床上下列几种为常见的先天性心脏病。兹将其主要X线征象分述如下: 一、房间隔缺损房间隔缺损多较大,好发于卵圆窝部,也可发生在上、下腔静脉开口附近,因左房排血阻力大于右房,一般在心房水平形成由左向右的分流。因此,右房、右室及肺动脉的血流量增多,负荷加重。上述心腔及肺动脉增大扩张,如肺循环阻力升高,则可引起肺动脉高压,但较少见。
Discusses several common primary signs of X-ray of congenital heart disease. Several clinically common congenital heart disease. It will be the main X-ray signs are as follows: First, atrial septal defect Atrial septal defect larger, occurs in the oval fossa Department, can also occur in the superior vena cava near the opening due to left atrial blood flow resistance greater than The right atrium generally forms a left-to-right shunt at the atrial level. Therefore, the right atrium, right ventricle and pulmonary artery blood flow increased, the load increased. The heart chamber and pulmonary artery enlargement and expansion, such as pulmonary vascular resistance, can cause pulmonary hypertension, but less common.
