About this study

Official title: Normal Reference Values in Han Adults of Extremity Arterial Structure and Hemodynamics by High-frequency Ultrasound: a Multi-center Study in China

In recent years, high-frequency ultrasound, due to its higher resolution, can clearly display the superficial vascular structure and blood flow, and can detect vascular lesions early, providing a new non-invasive tool for clinical observation of the structure and blood flow of the extremity artery. The purpose of this multi-center study is to establish the normal value of high frequency ultrasound for the structure and blood flow of the extremity arteries of Chinese Han adults, and to explore the influencing factors, so as to provide a quantitative reference for the early diagnosis, degree evaluation and curative effect observation of the structure and blood flow of the extremities.

Read the detailed description

The extremity artery is the peripheral blood vessel of the whole body, and it is often involved early in the diseases that are easy to damage the small vessels, such as atherosclerosis and connective tissue diseases. Early lower limb atherosclerosis mainly occurs in the dorsal foot artery, which is commonly seen in people with diabetes and long-term smoking. Connective tissue diseases such as systemic sclerosis and systemic lupus erythematosus also mainly involve small blood vessels, and vascular lesions may appear earlier than those of other specific organs such as heart and lung. Because of its shallow location, the extremity artery can be better used as a screening site for vascular diseases, and it is the window for early reaction of vascular diseases.However, the early stage of extremity artery disease is easy to be ignored, and patients often have pain and numbness of the affected limb. When the disease is severe, it can lead to ulcer not healing, and even limb gangrene and amputation, which greatly affects the quality of life and brings huge troubles and economic pressure to the patients. Therefore, early diagnosis of extremity arterial lesions is of great significance for early diagnosis of microvascular injury diseases such as atherosclerosis and connective tissue diseases, reducing the incidence of complications, and reducing the rate of amputation and mortality.

Ultrasound is a non-invasive imaging technique widely used in clinic. In recent years, with the development of ultrasound technology, the frequency of ultrasonic probes has been increasing. Because of its higher resolution, high-frequency ultrasound can clearly display the superficial vascular structure and blood flow, detect vascular lesions early, and accurately quantify the degree of stenosis, providing a new and beneficial tool for clinical observation of the structure and blood flow of the extremity artery. The purpose of this multi-center clinical study was to establish the normal value of high frequency ultrasound for the structure and blood flow of the extremities of Chinese Han adults, and to explore its influencing factors, so as to provide a quantitative reference for the early diagnosis, degree evaluation and curative effect observation of the structure and blood flow of the extremities.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • high-frequency ultrasoundDevice

    The volunteers will be given a high-frequency ultrasound examination of the extremity arteries, which is non-invasive, and the parameters of arterial structure and blood flow will be measured.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intima thickness of dorsalis pedis artery and proper palmar digital artery

    Intima thickness reflects the changes of vascular wall structure and is used for early evaluation of arterial disease.

    Measured: 1 day

Secondary outcomes (1)
  1. Blood flow velocity of dorsalis pedis artery and proper palmar digital artery

    Blood flow velocity reflects hemodynamic changes and is used for early evaluation of arterial disease.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy Volunteer and Artery Disease, run by First Hospital of China Medical University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 1 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Chunyan Ma, PHD (13998816448, cmu1h_mcy@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intima thickness of dorsalis pedis artery and proper palmar digital artery (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Aug 2023.
