Neck vascular injury symptoms?

summary

Neck vascular injury is a kind of injury that is much more serious than ordinary small wounds, so of course, there are more and greater injuries than ordinary injuries, such as massive hemorrhage and hematoma, which are very serious. Let's understand the symptoms of neck vascular injury together with me!

Neck vascular injury symptoms?

Acute injury can be manifested as the outflow of fresh blood from the wound. If the ejection or pulsatile outflow of bright red blood from the wound indicates arterial injury; If dark red blood flows from the wound, it indicates venous injury. It is worth noting that the high-speed bullet or high-speed metal debris impact on the bone, although the wound on the surface is very small, but the internal damage is extensive and bleeding is serious. It should also be noted that although the wound bleeding can stop itself, but in most cases, moderate vascular injury bleeding intermittent. In blunt closed injury, the blood at the vascular injury can flow into the body cavity, such as chest and abdominal cavity. The patients with blunt closed injury show severe hemorrhagic shock, and the mortality is higher.

Trauma and pain can aggravate shock, but the most basic reason is still hemorrhagic shock caused by bleeding. Open injury can roughly estimate blood loss, but closed injury is difficult to estimate blood loss.

After vascular injury, the bleeding not only flows to the body surface or body cavity, but also flows to the tissue space to form hematoma. If the bleeding flows to the mediastinum, it is manifested as mediastinum widening, dyspnea, chest pain, etc; If it flows to the retroperitoneum, abdominal pain and distension may occur. The hematoma communicates with the vascular hiatus to form a communicating hematoma, which has expansibility and pulsatility. This is an important local sign for the diagnosis of blunt vascular trauma.
