Forearm artery injury
Introduction
Introduction to forearm arterial injury Forearm arterial injury is mostly caused by sharp weapon injury, and car accident impact injury is also a common cause. More common in young adults aged 20 to 40. The forearm arteries mainly include the radial artery, the ulnar artery and the common interosseous artery, and the palmar arch and the deep palm arch formed by the hand. The hand arterial network formed by the shallow palm and the deep palm has a good compensatory effect, and the collateral circulation is beneficial to the compensatory effect of an arterial trunk injury of the forearm. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: Raynaud's syndrome
Cause
Causes of forearm arterial injury
(1) Causes of the disease
Stab wounds of sharp objects and stab wounds.
(two) pathogenesis
The forearm arteries mainly include the radial artery, the ulnar artery and the interosseous common artery, and the palmar arch and the deep palm arch formed by the hand, and the hand arterial network formed by the shallow palm and the deep palm have a good generation. For remission, the collateral circulation is beneficial to the compensatory effect of an arterial trunk injury in the forearm. Most of the causes of injury are caused by sharp stab wounds. Except for the wounds, the sharp thorns (edges) of the fractures are also It is easy to cause damage to the adjacent vascular trunk, and the arteries and veins may also be affected at the same time to cause arteriovenous fistula. It is also easy to cause damage to the accompanying nerve trunk (ulnar nerve, phrenic nerve and its branches). In the forearm arteries, the radial artery The incidence rate is high, and the iatrogenicity accounts for a considerable proportion. The main cause is thrombosis due to blood gas analysis and arterial blood pressure observation of the brachial artery.
Prevention
Forearm arterial injury prevention
Pay attention to the protection of the forearm in daily life to prevent injury and scratching during play and fight. Generally, after treatment, the prolapse of the radial artery is better. If the radial artery is blocked or ligated, or if the distal muscles of the limbs have undergone ischemic changes, it can cause Volkmann ischemic contracture and present a permanent disability of the affected limb. When the injury is found to be treated promptly, serious complications will not occur.
Complication
Forearm arterial injury complications Complications
When the crush injury is the main, the forearm artery injury, while the soft tissue is involved at the same time, it is prone to the forearm muscle interval syndrome, should be noted.
Symptom
Forearm arterial injury symptoms Common symptoms Toe is cold and cold,...
In addition to the symptoms of local injury, it is mainly manifested as partial obstruction of blood supply to the hand, including weakening and disappearance of ulnar artery or radial artery pulsation, cold feeling of fingers, skin allergies and numbness, such as damage to the superficial arch of the palm, and Renault can appear on the finger. (Raynaud) sign, there may also be a small fish atrophy sign.
Examine
Forearm artery injury examination
X-ray examination can eliminate fractures.
Diagnosis
Forearm artery injury diagnosis and differentiation
According to the trauma and clinical manifestations, it is not difficult to make a diagnosis, because the collateral circulation compensation function is better, except for 10% to 15% of the superior anastomosis of the palm artery arch, the treatment results are mostly good, therefore, unless it is necessary, generally do not An angiography is required.
