Decreased or absent carotid pulse

Introduction Decreased or disappeared carotid pulsation is one of the symptoms of polyarteritis. Multiple arteritis is 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 etiology of this disease is not clear. In recent years, it has been considered to be an autoimmune disease associated with immune complex deposition, and most of them may be associated with certain infections. At present, most people think that this disease may be an autoimmune disease related to infections such as streptococci, tuberculosis, and viruses.

Cause

The etiology of this disease is not clear. In recent years, it has been considered to be an autoimmune disease associated with immune complex deposition, and most of them may be associated with certain infections. At present, most people think that this disease may be an autoimmune disease related to infections such as streptococci, tuberculosis, and viruses. Some patients have detected anti-aortic antibodies, but the cause of the disease is not certain. The incidence is higher in Asia and Africa. More common in young women, the ratio of women to men is about 1:8.

Clinical diagnosis of typical clinical manifestations is not difficult to diagnose. Women under the age of 40 who have the following performances or more should be suspected of the disease.

(1) Ischemic symptoms appear in unilateral or bilateral limbs, indicating that the arterial pulsation is weakened or disappeared, and blood pressure is lowered or undetectable.

(2) Cerebral ischemia symptoms, manifested as weakened or disappeared unilateral or bilateral carotid pulsations, and vascular murmurs in the neck.

(3) Recent high blood pressure or refractory hypertension, accompanied by high-level vascular murmurs above the upper abdomen.

(4) Unexplained low fever, smelling vascular murmurs on both sides of the back spine, or on the sides of the sternum, the umbilicus, or the kidney, and the pulse changes abnormally.

(5) Patients without pulse and fundus lesions.

Differential diagnosis

Arterial stealing blood: Carotid steal syndrome refers to the internal carotid artery occlusion, the blood flow of the internal carotid artery flows through the anterior communicating artery into the affected side, and the blood flow of the internal carotid artery flows through the anterior communicating artery into the affected side. The onset of the internal carotid artery ischemic manifestation, or the vertebral-basal artery blood flow can flow back into the affected internal carotid artery through the posterior communicating artery, resulting in vertebral-basal artery ischemic manifestations, such as bilateral internal carotid artery occlusion. The blood supply by the vertebrobasilar artery and the external carotid artery can be accompanied by damage to the brain and cerebellum.
