Pilot Prospective Study of Two Methods of Revascularization of the Femoral Artery (SFA): Stenting in the SFA, and Stenting of the SFA, Supplemented by Fasciotomy in Hunter Channel.

Meshalkin Research Institute of Pathology of Circulation50 enrolled

Overview

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.

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.

Interventions

Angioplasty with stenting of the femoral arteryPROCEDURE

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

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. 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.
