font-size: 17px; text-align: justify; white-space: normal;">　　先说下肢深静脉血栓。<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;">　　下肢静脉又被称为人体的“第二心脏”。解剖学上分为深静脉和浅静脉。其向心反流主要依靠下肢肌肉的收缩。当然，瓣膜功能正常也是血液回流的必要条件。血流缓慢、静脉壁损伤、血液高凝状态都是下肢深静脉血栓形成的高危因素。<p style="margin-top: 0px; margin-bottom: 24px;

font-size: 17px; text-align: justify; white-space: normal;">　　下肢深静脉血栓的主要危害是肺栓塞和血栓后综合征。<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;">　　肺栓塞是由于栓子脱落随着回心血流进入肺动脉，引起肺栓塞，轻度肺栓塞可无明显症状，或只有咳嗽、胸闷、不适等轻微症状。如果脱落血栓体积较大或数量很多，就会出现胸闷、胸痛、咯血、呼吸衰竭等症状，甚至导致猝死。<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;">　　血栓后综合征是指深静脉血栓形成后出现慢性静脉功能不全的症状和体征，如不同程度下肢水肿和色素沉着。<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;">　　下肢静脉超声检查是一种无创、简便易行的影像检查方法，诊断准确性高，可在短时间内重复检查，是诊断下肢静脉血栓的首选检查方法，并可持续追踪观察后续治疗效果。<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;">　　正常的下肢静脉管腔的血流信号充盈良好，管腔可被完全压闭，管腔内部呈无回声，可见彩色血流。<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;">　　当出现下肢深静脉血栓时，管腔内呈低回声或等回声，管腔不能被压闭，内血流信号充盈缺损。<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; text-align: justify; white-space: normal;">　　下肢深静脉血栓形成按病程可分为急性期、亚急性期和慢性期，不同阶段其临床表现和治疗方法不同。<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;">　　急性期是指1-2周内的血栓，静脉内径增宽，管腔内可见低回声或极低回声，探头加压管腔无法关闭。甚至可以看到一些新鲜的血栓漂浮在管腔中。这种血栓极其危险，容易脱落。随着静脉血最终流入肺动脉，引起肺栓塞。<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;">　　一般在血栓形成后6-8小时内腔内溶栓有效。<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;">　　亚急性期是指数周以后的血栓。管腔内血栓回声增强，血栓变窄并附壁，血流部分恢复，可恢复静脉直径。<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;">　　慢性期为指数月至数年的血栓，血栓壁不规则增厚，呈等回声或强回声。血栓机化时，可与静脉壁难以区分，血流可再通或闭塞，形成侧支循环。<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;">　　事实上，下肢深静脉血栓形成是临床上的常见病、多发病。随着下肢深静脉血栓的发生，患者开始时可出现局部肢体肿胀。随着血栓形成的加剧，患者开始有疼痛感，尤其是行走时，站立时症状明显。主要原因是血液在深静脉内凝固，最后血栓形成造成一系列不良损害，会对患者下肢健康造成极大威胁。所以一定要及时给予针对性的治疗。
