吻合和附带循环之间的差异|比较类似术语之间的差异

这关键区别在吻合和附带循环之间吻合是指两个结构之间的手术连接，尤其是血管之间或肠道的两个环之间，而侧支循环是围绕被阻塞的替代循环动脉or静脉穿过另一条路径。

Anastomosis refers to a connection between two tubular structures such as blood vessels, two loops of intestine, etc. It is important, and collateral circulation takes place as a result of the this. Meanwhile, collateral circulation is an alternate blood circulating pathway which works when the main blood vessel is blocked or injured. It occurs around a blocked blood vessel, and it supplies enough blood for the tissues. Hence, collateral circulation is very important for patients suffering from缺血性中风，冠状动脉动脉粥样硬化和周围动脉疾病。

什么是吻合?

吻合是两个结构之间的联系，尤其是管状结构之间。它可以是血管之间的连接，也可以是肠子的两个环之间的联系。Circulatory anastomosis是指两个血管之间的联系：两个动脉（动脉吻合术），两个静脉（静脉吻合术），或一个动脉和静脉（动脉静脉吻合）之间的联系。

肠吻合指在手术上移除一部分肠道后，将肠子的剩余两个末端缝在一起。吻合可能是正常的或异常的。此外，它可以被获取或天生。先天性或获得的异常吻合术通常称为瘘管。

What is Collateral Circulation?

侧支循环是围绕阻塞的动脉或静脉围绕的替代血液循环途径。它通过先前存在的血管冗余或相邻血管之间形成的新分支发生。因此，它是专门的内源性旁路血管网络。抵押循环在患有缺血性中风，冠状动脉粥样硬化，周围动脉疾病以及其他疾病和疾病的患者中起着重要作用。它提供了防止缺血性损伤的保护。

这effectiveness of the collateral circulation in preventing infarction depends on the size of the blood vessels. If the diameter of the collaterals is smaller it is less likely to carry enough blood to prevent infarction. Furthermore, collateral arteries provide an alternative source of blood supply to the myocardium of heart in cases of occlusive coronary artery disease. Therefore, this coronary collateral function prevents possible heart attacks. Moreover, in the human brain, there is a network of collateral arteries in the circle of Willis, which lies at the base of the brain.

此外，侧外循环在猫中很有用，以便在有系统的血栓栓塞时向后腿提供血液。即使由于附带循环而阻塞了主血管，它们也获得足够的血液来进行组织。

吻合和附带循环之间有什么相似之处？

附近血管之间存在吻合术的结果是侧支循环。
Both anastomosis and collateral circulation facilitate the supply of blood into tissues when the main vessels are blocked.
吻合术和侧支循环都可以自然发生，也可以通过外科手术产生。
