Most of the broken blood vessels are caused by trauma, in general, if the venous vessels are broken, bleeding is less; if the arterial blood vessels are broken, bleeding is more; if the large arterial vessels are broken, it is easy to cause hemorrhagic shock, or even death. The on-site treatment of broken blood vessels includes wound compression and compression blocking in the direction of incoming blood, which should be promptly examined in a regular public hospital. If it is a small arterial or venous vessel that is broken, other vessels or collateral circulation will replace the original blood circulation and will not affect the normal blood supply, and the broken vessel can be ligated. If a large arterial or venous vessel is broken, it should be treated by vascular anastomosis in time to stop the bleeding. If vascular anastomosis cannot be performed in time, vascular transplantation or bypass can also be used to ensure normal blood supply to tissues and organs.
