静脉曲张和蜘蛛静脉之间的差异

静脉曲张与蜘蛛静脉

静脉曲张和蜘蛛静脉均呈浅表veins。即使听起来相似，这里也有许多差异在这里详细讨论，强调了它们的临床特征，症状，原因，调查和诊断，预后以及所需的治疗过程。

静脉曲张

Varicose veins occur on lower limbs most commonly. However, they can occur elsewhere, as well. Ex: Vulval varicosities; these appear during pregnancy. Veins are thin walled capacitance vessels. Their walls cannot withstand excessive pressures. The amount of平滑肌静脉壁内的内部明显小于在动脉壁中。静脉向心，，，，with the help of the pressure generated by surrounding muscles. These骨骼肌帮助静脉将血液带到心脏抵抗重力。沿着静脉划分为小隔间的静脉有小阀。随着较低隔室合同周围的肌肉，压力的增加将血液通过阀门向上推入上方的隔室。当肌肉放松时，阀门关闭。因此，血液不会流下。腿上有两个静脉系统。一个深层和肤浅的系统。这两个系统之间存在通信。这些通信称为“穿孔器”。静脉曲张是由于深，浅表或穿孔器系统中静脉瓣的无能引起的。 When venous valves do not function, a continuous column of blood forms along the vein. The vein wall cannot withstand this increased hydrostatic pressure, and it coils on itself. Thus, coiled and dilated superficial veins become visible. Valve incompetence is a common sequel of superficial venous clotting. The body mechanisms that dissolve a clot do not differentiate that well between venous valves and clots. It damages and destroys both. Varicose veins and ulcers, which follow superficial clot formation, are medically known as “后肢体肢体”。静脉曲张导致皮肤下的血液显着漏出静脉溃疡。静脉溃疡发生在腿部的内侧，疼痛，流血很多并且难以治疗。硬化疗法，Spaheno-Femoral结扎，刺伤和剥离是静脉曲张的常见治疗方式。静脉溃疡只要根本原因徘徊，就无法治愈。

蜘蛛静脉

Spider veins are also known asTelangectatsia。蜘蛛静脉是扩张的小静脉。它们通常围绕几毫米。即使蜘蛛静脉发生在任何地方，最常见的地点是脸部。毛细血管扩张有很多原因。先天性的原因包括葡萄酒污染，克利普尔·特雷纳纳综合症和遗传性出血性毛细血管扩张。库欣病，类癌综合征，血管瘤，硬皮病和辐射也引起蜘蛛静脉。有必要有良好的临床病史和彻底的体格检查来检测毛细血管扩张的根本原因。尽管硬化疗法会治疗蜘蛛静脉，但除非治疗根本原因，否则它们会复发。

静脉曲张和蜘蛛静脉有什么区别？

•静脉曲张静脉扩张，而蜘蛛静脉是小静脉。

•静脉曲张通常发生在腿上，而蜘蛛静脉在脸上出现。

•蜘蛛静脉是局部局部的，而静脉曲张可能会沿着腿部出现。

•静脉无能是静脉曲张的原因，而蜘蛛静脉可能是由于静脉壁的遗传缺陷所致。

•静脉曲张并未显示出明确的遗传联系，而某些类型的毛细血管扩张是遗传性的。
