问题乳腺癌可见哪些X线改变?

选项

答案

解析二尖瓣狭窄合并关闭不全与单纯二尖瓣狭窄，两者X线上均可见左房、右室增大和肺淤血。其主要区别点是前者尚可见左室增大，透视下可见心室收缩时左房出现扩张性搏动。左房和右室扩大较单纯二尖瓣狭窄为显著。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
