About

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.

Full 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.

Stenting of the femoral artery.

Active Comparator group

Description:

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 of all the extension is mounted.

Treatment:

Procedure: Angioplasty with stenting of the femoral artery

Stenting of the femoral artery and fasciotomy.

Experimental group

Description:

Under local anesthesia standard endovascular exposure is made and 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 of all the extension is mounted. 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.

Treatment:

Procedure: Angioplasty with stenting of the femoral artery, supplemented by fasciotomy in Hunter's channel
