Vascular injury
Introduction
Introduction Vascular injuries are classified as: complete disconnection, partial rupture, contusion of the vessel wall, tearing of the vascular intima and arterial spasm, hemorrhage, tension hematoma, and acute arterial insufficiency (pale, low skin temperature, numbness, dyskinesia, severe pain and The distal arterial pulsation disappears, and the symptoms of closed vascular injury such as open blood vessel injury or insufficient blood supply, interruption and blood flow restriction at the distal end of the limb. Any open or indirect violent invasion of blood vessels may result in open or closed vascular injury.
Cause
Cause
The causes of vascular injury are complex and the classification is also inconsistent. According to the force situation, it can be divided into direct damage and indirect damage; according to the injury factor can be divided into sharp damage and blunt injury; according to the continuity of the damaged blood vessel can be divided into complete fracture, partial fracture and vascular contusion; The degree of vascular injury can be divided into light, medium and heavy injuries.

Examination and diagnosis of vascular injuries:
Complete disconnection, partial rupture, contusion of blood vessel wall, tear of endarterial membrane and arterial spasm, hemorrhage, tension hematoma and acute arterial insufficiency (pale, low skin temperature, numbness, dyskinesia, severe pain and distal arterial pulsation disappeared The symptoms of closed vascular injury such as open vessel injury or insufficient blood supply, interruption, and blood return to the distal extremity.
1. According to the state of vascular injury, it should be divided into complete disconnection, partial rupture, contusion of blood vessel wall, tear of endothelium and arterial spasm. The first two are open wounds of the blood vessels, and the latter three are closed blood vessels.
2. Check for bleeding, tension hematoma and acute arterial insufficiency (pale, low skin temperature, numbness, dyskinesia, severe pain and distal arterial pulsation) and other open blood vessels or insufficient blood supply, interruption and distal limbs Symptoms of closed vascular injury such as blood reflux disorders.
3. Individual difficult cases can be used for angiography.
4. To find out whether there is shock, fracture, dislocation and nerve injury.
Diagnosis
Differential diagnosis
Identification of symptoms that are easily confused with vascular injuries:
Vascular malformations: vascular tumors are also called tubular tumors, or hemangioma, lymphangioma, respectively; but some vascular lesions are not true tumors, so they can only be called vascular malformation. It is a tumor or deformity derived from blood vessels or lymphatic vessels. Generally speaking, vascular malformation is a group of abnormal mature blood vessels with certain occupying properties, and the damage is mainly due to rupture and bleeding, or vascular embolism.
