Brachial artery injury
Introduction
Introduction to radial artery injury Brachial artery injury occurs in children, mainly causing ischemic contracture of the forearm and hand muscles. Once the radial artery is completely blocked, due to insufficient blood supply to the elbow joint vascular network, it is unable to escape the ischemic necrosis of the distal forearm. Doom, in order to avoid the sequela of this permanent disability, should use a variety of inspection methods, including surgical incision, etc., in order to avoid this serious consequence. basic knowledge The proportion of illness: 0.001% Susceptible people: good for children Mode of infection: non-infectious complication:
Cause
Cause of radial artery injury
(1) Causes of the disease
In addition to guns, bullets can cause injuries, and local fractures are more common.
(two) pathogenesis
The radial artery is connected to the radial artery (the lower edge of the great round muscle), and the lower end is 2.5 cm below the elbow fossa. The lower part is divided into two ulnar artery and the radial artery. The incidence of injury is high, except for gunshot wounds and shrapnel injuries. The humeral shaft and the supracondylar fracture of the humerus are common causes of damage. The middle part of the humerus is easily associated with sacral nerve and median nerve injury. In the upper part of the iliac crest, the median nerve involvement is more common, and the total companion rate is up to 60% to 70%.
Prevention
Radial artery injury prevention
The disease is caused by trauma directly affecting the tibia, such as kicking, falling or violent fighting. Therefore, pay attention to living habits, high-risk workers, such as construction workers, mining workers are prone to damage, should pay attention to protect themselves in the course of work. Pay attention to calmness and avoid emotional conflicts leading to the disease. Secondly, early detection, early diagnosis and early treatment are also important for the prevention of this disease.
Complication
Radial artery injury complications Complication
Volkmann ischemic contracture can often be complicated.
Symptom
Symptoms of radial artery injury Common symptoms Forearm and hand muscles...
With the basic symptoms of vascular injury, the following characteristics should be noted for each artery segment:
1. The lower part of the radial artery is the most common in clinical practice. It occurs in children, especially in the supracondylar fracture of the humerus. It mainly causes ischemic contracture of the forearm and hand muscles. It is called Volkmann ischemic contracture. Causing disability consequences (Figure 1).
2. In addition to the humeral shaft fracture, the middle iliac artery injury can also cause secondary thrombosis through the radial artery through the catheter and percutaneous puncture, resulting in the same consequences for the forearm and hand; in this case, the median nerve is also It is prone to dysfunction.
3. The upper part of the radial artery is less common than the former two. Because the lateral branch of the vascular network of the shoulder joint is rich, once it is blocked, its effect on limb blood supply is lighter than the former two.
According to the above diagnosis points, the diagnosis of radial artery injury is generally more difficult. The key is to require early diagnosis, especially the supracondylar fracture of the humerus combined with vascular injury, or the suspicious injury in the middle of the radial artery. Once the radial artery is completely blocked, due to the elbow joint Insufficient blood supply to the vascular network can not escape the fate of ischemic necrosis of the distal forearm. In order to avoid the sequela of this permanent disability, various examination methods, including surgical incision, should be used to avoid this. Serious consequences.
Examine
Brachial artery injury examination
No relevant laboratory tests.
X-ray examination can exclude bone damage.
Diagnosis
Diagnosis and diagnosis of radial artery injury
diagnosis
The disease is a surgical disease, and the disease can be clearly diagnosed according to the injury and clinical manifestations.
Differential diagnosis
Need to distinguish from rupture of iliac aneurysm, the former is usually caused by violent direct action on the radial artery and its tissue to cause vascular damage, sharp injury is common. The latter is caused by a fall or other cause of blood pressure to break through the normal vascular mucosa caused by radial artery rupture, according to the onset of the disease can be distinguished.
