About this study
This is a Prospective randomized controlled study to evaluate the difference of safety，effectiveness between chocolate balloon and plain balloon dilatation in treatment of infrapopliteal artery lesions.
Read the detailed description
Prospective randomized controlled study to evaluate the difference of safety，effectiveness between chocolate balloon and plain balloon dilatation in treatment of infrapopliteal artery lesions. Patients with femoral-popliteal artery lesions in our department were randomly assigned to the chocolate balloon group and plain balloon dilatation group. Compare the ischemic improvement rate (limb salvage rate, postoperative patency rate) and the complications rate of two different treatments.

Questions about this trial
What is this clinical trial studying?
A study testing chocolate balloon and plain balloon in people with Atherosclerosis and Ischemia, run by Xuanwu Hospital, Beijing at 1 site in China.

Who may be eligible to take part?
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 12 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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.

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact yang Li, M.D. (18810432268, liyang0603@aliyun.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
12-month Primary Patency Rate (time frame: 12 months). 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 12 Oct 2022.
