室间隔缺损伴有大的左向右分流的婴儿的特征是快而浅的呼吸和肋间隙下陷。这些体征通常是由于肺血管床充血致使肺的顺应性降低而产生的。有些患儿在临床上首先出现气道阻力增加的现象,如喘息、肺过度膨胀和大叶性肺气肿。本文总结了5年内作者遇到的10例以阻塞性肺部病变为主要临床表现的室间隔缺损患儿的诊治经验。肺的改变与血流动力学异常的严
Ventricular septal defects associated with large left-to-right shunting are characterized by fast and shallow breathing and intercostal space sag. These signs are usually due to reduced lung compliance due to pulmonary vascular bed congestion. Some children first clinical manifestations of airway resistance increased phenomenon, such as wheezing, excessive lung expansion and lobar emphysema. This article summarizes the diagnosis and treatment experience of 10 cases of ventricular septal defect with obstructive pulmonary lesion as the main clinical manifestation in 5 years.
