A Prospective, Multicenter, Observational Study on the Treatment of Chronic Common Femoral Artery Bifurcation Occlusion (EAST-CFA)

October 30, 2022 updated by: Qingdao Hiser Medical Group
This study is a prospective, multicenter real-world observational study to understand the safety and efficacy of endoluminal therapy and traditional endometristomy in the real world for patients with severe stenosis and occlusion of the common femoral artery. The study will enroll 300 patients with severe stenosis and occlusion of chronic common femoral artery in nine centers across the country. According to the different intervention methods of the common femoral artery, the enrolled cases were divided into two groups: A: endometrial detachment for common femoral artery lesions and B: interventional endovascular treatment for common femoral artery lesions. As it is a real-world study, there is no separate primary endpoint indicator, which mainly observes F-TLR (immunity from vascular re-intervention), technical success rate, duration of surgery, length of hospital stay, common femoral artery patency rate, deep femoral artery patency rate, direct and indirect medical expenditure associated with the disease in 24 months, MAE (major adverse events), and perioperative complications.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

Patients with severe chronic primary stenosis or occlusion of the common femoral artery (including the femoral artery bifurcation) requiring endovascular therapy or plaque stripping were enrolled

Description

Inclusion Criteria:

  1. Patients with chronic atherosclerotic occlusion who are over 18 years old;
  2. Patients with Rutherford clinical grading range in the range of 2-5;
  3. The stenosis rate of the common femoral artery (including the bifurcation of the femoral artery) is > 60% or occlusive, and it is proposed to undergo intraluminal treatment such as balloon dilation, stent implantation, plaque rotation and excision, or endometrial decortication treatment;
  4. At least one healthy sub-knee outflow tract (or opened through reconstruction) communicates with the blood vessels of the foot;
  5. Intravascular treatment: the guide wire successfully passed through the target lesion;
  6. For patients with combined aorta iliac artery lesions, after completing the reconstruction of the main iliac artery, they can be enrolled according to the above requirements; except for the ipsilateral iliac artery, other non-target lesions of the remaining non-target blood vessels can be treated by the doctor at his own discretion;
  7. For patients with both lower limbs that meet the admission conditions, both limbs can be enrolled separately in chronological order;
  8. Written informed consent prior to the study procedure.

Exclusion Criteria:

  1. Patients who are unwilling or refuse to sign informed consent;
  2. Known or suspected allergy or contraindications to aspirin, clopidogrel bisulfate, heparin or contrast agents;
  3. Patients who have participated in clinical trials of other drugs or medical devices that interfere with this clinical trial in the past 3 onths;
  4. pregnant and lactating women;
  5. Life expectancy is less than 24 months;
  6. Patients whose common femoral artery has received endometrial detachment, plaque rotation, stent implantation and restenosis in stents;
  7. Patients with acute ischemia of grade III lower extremities who have lost the opportunity for vascular reconstruction;
  8. Any major medical condition that the researchers believe may affect the subject's optimal participation in the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
