Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Screening It is performed in patients with a verified diagnosed occlusive lesion of the femoropopliteal segment above the knee (type D by TASC II classification), with chronic limb ischemia (3-6 categories by Rutherford classification). Assessment of inclusion / exclusion criteria, assigning a patient number.
Study inclusion Collecting baseline information about the patient (anamnesis, including information about concomitant therapy, data from the initial physical examination, ultrasound data of the lower limb arteries, CT-angiography data, assessment of the quality of life using the SF-36 questionnaire). Randomization using the envelope method to one group or another.
Surgical intervention:
Group 1 (n=50): Recanalization of prolonged occlusion of the arteries of the femoral-popliteal segment above the knee with angioplasty and stenting with a biomimetic interwoven nitinol stent; Group 2 (n=50): Recanalization of prolonged occlusion of the arteries of the femoropopliteal segment above the knee with angioplasty and stenting with a biomimetic interwoven nitinol stent, supplemented by fasciotomy in Gunter's canal.
Follow up: 6, 12, 24 months.
Performed:
Triplex ultrasound of one lower limb (restenosis, thrombosis, stent breakage); Radiography of the operated limb in two projections, for patients in whom a stent breakage is suspected according to ultrasound; Consultation with a cardiovascular surgeon. For each patient participating in the study, a CRF is filled out in a form convenient for the Investigator. The creation of a folder "Investigator's file" is provided, which stores all the necessary documents provided for by the rules of "Good Clinical Practice".

Hubrid revaskularization
Patients (n=50) with recanalization of the femoral-popliteal arterial segment above the knee with angioplasty and stenting with a biomimetic interwoven nitinol stent, supplemented by fasciotomy in Hunter's canal.
recanalization of the femoral-popliteal arterial segment above the knee with angioplasty and stenting with a biomimetic interwoven nitinol stent, supplemented by fasciotomy in Hunter's canal.
Under local anesthesia, a standard endovascular approach is performed. Transluminal or subintimal recanalization of the occluded arterial segment is performed with a hydrophilic guidewire. Next, balloon angioplasty of the recanalized segment is performed. After control angiography, a biomimetic interwoven nitinol stent is placed throughout the lesion. Immediately after the stenting procedure, under local anesthesia, access to the distal part of the SFA at the outlet of Hunter's canal and 1 portion of the popliteal artery is performed. The lamina vastoadductoria is dissected. The wound is sutured in layers. An aseptic bandage is applied. Drug therapy includes pre-procedure clopidogrel (160-300 mg/day), starting at least one day before, and intra-procedure heparin (100 U / kg body weight intravenously). After the procedure, all patients have prescribed double antiplatelet therapy (aspirin+clopidogrel (75 mg per day) within 6 months and then aspirin 75 mg for a long time.
Endovascular treatment
Patients (n=50) with recanalization of the femoral-popliteal arterial segment above the knee with angioplasty and stenting with a biomimetic interwoven nitinol stent.
recanalization of the femoral-popliteal arterial segment above the knee with angioplasty and stenting with a biomimetic interwoven nitinol stent.
Under local anesthesia, a standard endovascular approach is performed and the affected arterial segment is visualized. Transluminal or subintimal recanalization of the occluded arterial segment is performed with a hydrophilic guidewire. Next, balloon angioplasty of the recanalized segment is performed. After control angiography, a biomimetic interwoven nitinol stent is placed throughout the lesion. Drug therapy includes pre-procedure clopidogrel (160-300 mg/day), starting at least one day before, and intra-procedure heparin (100 U / kg body weight intravenously). After the procedure, all patients have prescribed double antiplatelet therapy (aspirin+clopidogrel (75 mg per day) within 6 months and then aspirin 75 mg for a long time.
