font-size: 17px; white-space: normal; text-align: center;"> <p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　静脉淤血影响下肢血液循环，下肢静脉曲张可能会导致以下危害:<p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　一、静脉曲张发生后，由于静脉淤血影响下肢血液循环，皮肤营养供应会受到影响，下肢会出现色素沉着，严重时会出现皮肤溃疡。<p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　第二:下肢静脉曲张发生后，通常会导致患者出现临床症状，如下肢肿胀、疼痛等。如果并发血栓性静脉炎，局部肿痛会很严重。确诊为下肢静脉曲张后，一定要及时治疗，防止病情恶化。我们可以保守治疗，比如穿弹力袜，比如抬高患肢。如果病情比较严重，建议积极进行手术治疗，如高位结扎、曲张静脉剥脱术等。<p style="margin-top: 0px;

font-size: 17px; white-space: normal; text-align: center;"><p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　下肢静脉曲张的原因:<p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　下肢静脉曲张的原因可以总结为一个，就是静脉压增高导致浅静脉曲张，这是最基本的原因。所有可能导致下肢静脉压升高的情况都可以称为病因。<p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　肥胖、长期从事重体力劳动、长时间站立的人，如教师、外科医生、工人或厨师等，容易患下肢静脉曲张。下肢静脉瓣膜功能不全包括股总静脉、股浅静脉、腘静脉瓣膜功能不全，或股静脉与大隐静脉交界处的股大隐静脉瓣膜功能不全，交通支瓣膜功能不全可导致浅静脉曲张。<p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　另一个原因是髂静脉受压。这种典型的疾病称为髂总静脉压迫综合征，因为压迫髂总静脉会导致局部管腔狭窄，然后远端静脉压升高，导致下肢静脉曲张。<p style="margin-top: 0px; margin-bottom: 0em; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; white-space: normal; text-align: center;"><img data-s="300,640" data-galleryid="" data-type="png" class="rich_pages wxw-img" src="https://mmbiz.qpic.cn/mmbiz_png/wPICchzd6lYHpsibfCFichPibmWbErubKd4sGpZChGnzSbH0pWeYYkZicwVUQ4xV6ibJTfCYMSCZ2l56CaokKnKDhicg/0?wx_fmt=png" data-ratio="0.3261608154020385" data-w="883" data-imgqrcoded="1" style="margin: 0px; padding: 0px; max-width: 100%; height: auto !important; vertical-align: bottom;"/><p style="margin-top: 0px; margin-bottom: 0em; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; white-space: normal; text-align: center;"> <p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　另一个常见的原因是深静脉血栓形成后，由于深静脉瓣膜破坏和管腔狭窄，肾静脉压力增加，压力传导至浅静脉，造成浅静脉曲张。另一种是动静脉畸形，即动静脉之间存在连通，动脉压力传递到静脉系统，导致静脉系统静脉曲张。还有一种静脉畸形叫先天性畸形，是大量的静脉肿块，可在皮肤和外观上表现为静脉曲张。这些因素都会导致下肢浅静脉曲张。<p style="margin-top: 0px; margin-bottom: 24px; padding: 0px; min-height: 1em; color: rgb(51, 51, 51); font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; text-align: justify; white-space: normal;">　　下肢静脉曲张患者平时可以多吃些海带、紫菜、海蜇、贝类等富含碘的食物。此外，黑芝麻、葵花籽、乳制品、叶菜等富含氨基酸的食物也有助于提高人体的抗寒能力。尽量避免肥肉、油炸、烧烤等食物。这样，只有配合手术和药物治疗，才能达到根本康复的目的。
