The Acute and Long-term Clinical Outcome of Self- Expandable Stent in Complex Proximal Superficial Femoral Artery Lesions Involving the Femoral Bifurcation

Not yet recruiting
Conditions
Common Femoral Artery Occlusive Disease
Interventions
Procedure: endovascular treatment
Registration Number
NCT04713865
Lead Sponsor
Qingdao Hiser Medical Group
Brief Summary

The stent-FP study investigates the impact of coverage of profound femoral artery (PFA) by bare metal stent deployed in proximal superficial femoral artery (SFA) lesions. 300 patients with femoral bifurcation lesions will be included and divided into 3 groups according to the location of proximal stent edge. The primary endpoint of the study is major adverse events and freedom from target lesion revascularization at 48 months. Secondary endpoints include primary patency of PFA and bare metal stent at 1,6, 12,24,36and 48 month, MAE and F -TLR at 1,6, 12,24,36 month.

  3. Patients is willing to follow-up on time
  4. Patient has a life expectancy of at least 24 months
  5. Prior to enrolment, the guidewire has crossed target lesion
  6. De novo lesions located in the femoral artery bifurcation (5mm between distal CFA and proximal SFA), need for primary bare metal stent implantation
  7. There is a patent deep femoral artery demonstrated by angiography
  8. If the first-time endovascular treatment is failure, patients undergo endovascular treatment successfully at the second time, the patients can still be enrolled (9)For patients with aortoiliac artery lesions, they can be enrolled after the successful reconstruction of aortoiliac artery .

(10) The lower extremity artery needs to have a healthy runoff of no less than 10 cm above the ankle, and at least one healthy dorsalis pedis artery, medial or lateral plantar artery connected with the digital artery below the ankle (11) Informed consent signed by patients

Exclusion Criteria

  2. In the past 3 months, they have participated in other drugs that interfere with this clinical trial or patients in clinical trials of medical devices
  3. Pregnant and lactating women
  4. Patients with other diseases that may make the trial difficult or significantly shorten the patient's life expectancy (<2 years), such as tumors, severe liver disease, cardiac insufficiency, etc or patients whose life expectancy is less than 24 months (24 months of follow-up are required)
  5. Patients with acute arterial thrombosis or embolism at the target lesion site.
  6. Patients who underwent stent implantation in common femoral artery previously

(8) Use of thrombectomy, atherectomy or laser devices during procedure (9) Previous open surgery in the same limb . (10) Patients with deep femoral artery totally occlusion
