hand vascular injury
Introduction
Introduction to hand vascular injury Vascular trauma is more common in wartime or in peacetime. Among them, vascular injuries in the extremities are the most common, followed by vascular injuries in the neck, pelvis, chest and abdomen. Recently, with the development and popularization of endovascular treatment, medical sources Sexual vascular injury is also increasing. In vascular injury, arterial injury is more common than veins, and combined injury with action veins and individual venous injuries also occur. The blood supply to the hand is extremely rich, the main source is the radial artery and the ulnar artery; there are still the interosseous anterior artery and the posterior interosseous artery; in addition, 3.7% of the individuals have the median artery. These blood vessels are in the form of an arterial network or an arterial arch, which constitutes a channel for comfortable transportation. It ensures that the hand is pinching, holding, grasping and holding a variety of functional positions, and the blood supply has a strong adaptability. The compensatory ability is good, so the survival rate of the hand can still reach about 1/3 among the injured patients with complete rupture of the ulnar artery and the radial artery. basic knowledge The proportion of illness: 0.003% Susceptible people: no special people Mode of infection: non-infectious Complications: ischemic necrosis
Cause
Cause of hand vascular injury
Cutting, sharps or bullets can cause injury.
Prevention
Hand vascular injury prevention
There is no effective preventive measure for this disease, and timely detection of timely treatment is the key to the prevention and treatment of this disease.
Complication
Hand vascular injury complications Complications ischemic necrosis
Severe hand vascular injury can be complicated by all ischemic necrosis.
Symptom
Symptoms of vascular injury in the hand Common symptoms Loss of hand function
The blood circulation in the hand is very rich. Under normal circumstances, the ulnar artery or the radial artery is broken, which will not affect the blood circulation of the hand. However, due to the ruler, the shallow arch of the radial artery may be mutated, sometimes the ulnar artery or the radial artery is damaged. It may jeopardize the blood supply of some fingers, and should still be taken seriously, and should be carefully examined. Sometimes the ulnar artery and the radial artery are completely broken at the same time, as long as the soft tissue on the dorsal side of the wrist is intact, such as the dorsal artery of the bone and its collateral circulation. Compensation does not affect the blood supply to the hand. In this case, even if the injured tendon is not repaired, the ulnar artery does not generally cause ischemic necrosis. However, the injury of the main artery of the hand may be possible. Will not cause ischemic necrosis of the hand, but after all, it will lead to insufficient blood supply to the hand, and the function of the opponent will have a certain impact.
Examine
Examination of hand vascular injury
X-ray examination, no positive findings.
Diagnosis
Diagnosis and diagnosis of hand vascular injury
According to the history of trauma, the location of the injury and the clinical bleeding, the diagnosis is not difficult.
