问题 风湿性二尖瓣狭窄有哪些手术适应证?
选项
答案
解析 无症状或心功能属于Ⅰ级者,不主张施行手术。心功能Ⅱ级以上者均应手术治疗。重度狭窄伴有功能性三尖瓣关闭不全的病例,施行闭式二尖瓣交界分离术后仍可获得较好疗效。二尖瓣狭窄伴有关闭不全,以及二尖瓣狭窄伴有明显主动脉瓣病变,则不宜作闭式二尖瓣交界分离术。妊娠病人如心功能属于Ⅱ级、Ⅲ级,宜在妊娠早期施行手术,以防妊娠后期症状加重。

错误信息

  • 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.
