Why can’t I feel my pulse?

"Subclavian artery steal syndrome" cannot be ruled out

This syndrome is mainly caused by the stenosis of the subclavian artery, a branch of the heart blood vessels, resulting in insufficient blood originally sent to the hands. As a result, blood from the brain is "stolen" to the upper limbs through the vertebral artery. Because the blood in the brain is "stolen", insufficient local blood flow can cause a stroke.

Subclavian artery Stenosis is mostly caused by atherosclerosis, which is the same reason as general blood vessel obstruction, that is, high blood pressure, hyperlipidemia, hyperglycemia, etc., lead to atherosclerosis, plaque formation, and then plaque formation. The detachment blocks a certain blood vessel, or even the entire blood vessel is blocked. In a small number of patients, it is caused by arterial dissection, congenital vascular sclerosis and blood vessel inflammation.

The pulse in the left hand cannot be felt because of the clavicle The lower arteries were stenotic and occluded, resulting in insufficient blood flow in the hands and weak pulses. At the same time, because the vertebral arteries "stole" part of the blood in the brain, the aunt felt weak in her hands and feet, felt dizzy, and even fainted.

Clinically, head and carotid artery angiography examination found that the proportion of subclavian artery stenosis was 16%. Since the brain has other collateral circulation to support, only 1/3 of the patients will suffer from subclavian artery stenosis. Steal syndrome causes stroke. If the patient feels dizzy when shaking his hands or lifting heavy objects, he should immediately stop hand movements and sit or lie down to rest to help blood flow back to the head and neck. If the intensity of the pulse beats in the two hands is different If the blood pressure of the two arms differs by more than 20 mmHg, you should pay attention to whether there may be subclavian artery stenosis. If you have unilateral weakness in your hands and feet and unclear speech, you should seek medical treatment immediately. For treatment, generally use Interventional balloon dilation technology dilates the stenotic subclavian artery.
