Decreased and absent ulnar or radial pulse

Introduction The forearm artery mainly consists of the radial artery, the ulnar artery and the common interosseous artery, and the palmar arch and the deep palm of the hand that are subdivided into the hand. Forearm arterial injury mainly manifests as partial obstruction of blood supply to the hand, including weakening and disappearance of ulnar artery or radial artery pulsation, cold finger sensation, skin irritation and numbness.

Cause

Stab wounds of sharp objects and stab wounds.

an examination

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. If the injury affects the superficial arch of the palm, the Raynaud sign may appear on the finger, and there may be a sign of atrophy in the small fish. 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 anastomotic arch anastomosis, the treatment results are mostly better. Therefore, angiography is generally not required unless it is necessary.

Differential diagnosis

Carotid pulsation weakened or disappeared: one of the symptoms of multiple arteritis, multiple arteritis, also known as primary arteritis syndrome, aortic arch syndrome, avascular disease or Takayasu`s disease. The incidence rate in the eastern countries is higher, more common in young women.

The dorsal artery pulsation disappears: lower extremity atherosclerosis is often accompanied by numbness of the extremities, and the pulsation of the dorsal artery of the foot disappears. The disease is more common in middle-aged and elderly people, often accompanied by a history of hypertension. The early symptoms are mainly intermittent claudication, and the pain at rest is the manifestation of severe ischemia of the lower extremities, often accompanied by numbness of the extremities. Acromegaly ulcers and gangrene can also occur in the advanced stage. Physical examination revealed a decrease in extremity skin temperature, a stenosis, or a weakening or disappearance of the distal arterial pulsation of the occlusion artery. Doppler ultrasound and angiography can be used to determine the location, extent and extent of the disease and contribute to the choice of surgical approach.

Arterial pulsation weakened or disappeared: the arterial position was deep, adjacent to the femoral surface and the posterior portion of the knee joint capsule. The outer edge of the semitendinosus muscle is obliquely outward, and the femoral condyle is horizontally located in the posterior middle part of the knee, and then vertically down to the lower edge of the muscle, and is divided into the anterior iliac artery and the posterior tibial artery. The former enters the anterior region of the calf through the upper edge of the interosseous membrane, and the latter passes through the deeper part of the soleus tendon to the posterior region of the calf. In addition to the distribution of muscle branches in the adjacent muscles, there are five joint branches, namely the internal and external laparoscopic arteries, the middle knee artery and the inferior and lateral arteries of the knee, all of which are involved in the formation of the knee arterial network.
