About this study

Official title: Pilot Prospective Study of Two Methods of Revascularization of the Superficial Femoral Artery: Stenting in the Superficial Femoral Artery, and Stenting of the Superficial Femoral Artery, Supplemented by Fasciotomy in Hunter Channel in Patients With Steno-occlusive Lesions of Femoral-popliteal Segment TASC C, D

Comparison of two methods for revascularization of the superficial femoral artery: stenting of the superficial femoral artery vs. stenting of the superficial femoral artery supplemented with fasciotomy in Hunter canal in patients with steno-occlusive lesion of the femoro-popliteal segment of TASC C, D.

Read the detailed description

Physiological flexions and extensions in hip and knee joints cause dramatic deformity in stented femoral and superficial femoral arteries, both axially and angularly. As a result, stents get broken, restenosed or thrombosed. Some researchers report a 20 to 46% two-year incidence of broke stents in the superficial femoral artery, while restenosis and occlusion incidence vary from 21.8% to 53.3% . In addition to axial and angular stress, contributing to this untoward effect is musculofascial sheath which houses the artery in distal thigh.

Investigators suggest that standard stenting of an artery be augmented by incision of the anterior musculofascial sheath (septum intermuscular vastoadductoria) that will increase the mobility of distal part of the femoral artery, which will decrease frequency breakage of stents. Review of the world literature yielded no peer instances of such improvement of stenting outcomes in the said arteries.

What participants receive

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

  • Angioplasty with stenting of the femoral arteryProcedure or surgery

    A standard endovascular exposure is carried out under local anesthesia and a lesioned arterial segment is visualized. Stenosis or artery occlusion is passed by the hydrophilic guide. During the occlusion transluminal or subintimal artery recanalization (most frequently mixed) is conduced. Then balloon angioplasty of stenosis or occlusion are carried out. After the angiographic control if necessary stent (balloon extpandable or self-expanding) of all the extension is mounted.

    Medical therapy includes aspirin (acid acetylsalicylic) prescription before the procedure (160 - 300 mg/d), beginning from minimum per day and heparin (heparin sodium) injection during the procedure (5000 U iv). After the procedure aspirin (acid acetylsalicylic) in dose 100 mg/d within long period should be prescribed in all the patients, and plavix (clopidogrel) in dose 75/d should be prescribed within 3 months.

  • Angioplasty with stenting of the femoral artery, supplemented by fasciotomy in Hunter's channelProcedure or surgery

    Standard endovascular stenting of femoral artery. The exposure is carried out to the distal part of superficial femoral artery when it lives Hunter's canal and the first portion of popliteal artery. Intermuscular vastoadductoria sept is dissected and the following arteries are ligated and dissected: а. superior medialis genus, а. superior lateralis genus.

What is being measured

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

  1. Ankle-brachial index

    Change in ankle-brachial index.

    Measured: Baseline, 3 days after the operation, 6 month, 12 month, 2 years

  2. Ultrasound scan of the operated segment

    The degree of stenosis in the operated segment.

    Measured: Baseline, 3 days after the operation, 6 month, 12 month, 2 years

  3. CT-angiography of lower limb arteries

    The degree of stenosis in the operated segment. CT-angiography of lower limb arteries at the control points will be done only if the detection of steno-occlusive lesions of the operated segment during the observation period, confirmed by ultrasound.

    Measured: Baseline, 3 days after the operation, 6 month, 12 month, 2 years

Secondary outcomes (3)
  1. Number of participants with a successful procedure of revascularization.

    Number of participants with a successful procedure of revascularization.

    Measured: During the operation.

  2. Number of participants with complications during the operation.

    Number of participants with complications during the operation.

    Measured: During the operation.

  3. Number of participants with limb salvage

    Number of participants with limb salvage.

    Measured: 3 days after the operation, 6 month, 12 month, 2 years

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ankle-brachial index (time frame: Baseline, 3 days after the operation, 6 month, 12 month, 2 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02590471, which also lists 1 linked publication.

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.
