Exceptions There is a catch, however. There are some extremely rare exceptions involving rare heart defects where holes in the walls of the heart allow for blood (and blood clots arising in the veins) flowing from the right side of the heart to bypass the lungs and enter the left side of the heart directly. In such cases, part of a blood clot arising in the venous system can travel to the brain to cause a stroke. This condition is called 'paradoxical embolism'.
我老妈在中国，马上93周岁了，血压正常，血脂血糖有点高，除了说腿没劲 平时没啥大毛病。前天晚上在沙发那烫脚 然后就慢慢晕过去，我姐马上打120，120人让把她放平了，当我姐慢慢拖她时候 她就慢慢地醒了。120来了 查一下血压160，说没啥事不建议送医院，现在医院人满为患。请问像我妈这是啥情况？危险吗？如果现在没法住院做全面检查的话，最需要检查什么？谢谢
昏迷（小中风）。但如果血栓很小，平躺，血压升高后，可以再度冲走。如果是我，做脑部CT，查静脉血栓。
120的医生把她放平身体，就是要让血液回流到脑部。

TBz 说的情况，可能性大得多。认同。

都是血往四肢跑， 大脑供血不足， 就眼前一黑
2. 你说：” 扯啥呢，间隔缺损能活到九十多岁？“ 请不要这么武断，腿部血栓进入脑部，有多种可能途径，不一定必须有间隔缺损。你凭什么马上判断是间隔缺损呢？
