In clinical practice, once a patient has a bleeding carotid artery, the bleeding site should be effectively compressed to stop the bleeding. At the same time, the patient should be treated differently for different reasons. For example, if the bleeding is caused by an invasive operation and the patient’s carotid artery is misperforated, the patient’s coagulation should be observed in addition to effective compression to stop the bleeding. If the patient’s coagulation function is normal, most of the patients will often stop bleeding at the bleeding site after a long period of effective compression to stop the bleeding, but a small number of patients will have a more obvious subcutaneous hematoma, or even suffocation due to the subcutaneous hematoma compression, resulting in the patient’s death. Another aspect of carotid artery hemorrhage is the rupture of the carotid artery due to trauma. Since the carotid artery is a large artery and is close to the heart, a rupture of the carotid artery can cause death due to hemorrhagic shock. In addition to timely compression to stop bleeding, the patient should seek medical attention in the nearest hospital for effective anti-shock treatment, blood transfusion, surgical anastomosis and other related measures.
