Effect of a femoral arteriovenous fistula on lower extremity venous hemodynamics after femorocaval reconstruction

Abstract

AVFs increased flow through the femorocaval grafts, yet they impeded venous return. The ideal AVF-to-graft ratio used in our study was 0.375, because it increased graft flow, permitted forward flow in the femoral vein while reducing pressure, and improved venous return with exercise.

Iliofemoral Deep Vein Thrombosis: Conventional Therapy Versus Lysis and Percutaneous Transluminal Angioplasty and Stenting

“…5,6 Recent studies have shown, however, that surgical thrombectomy may provide long-term iliac venous patency rates of approximately 80% when combined with the creation of an arteriovenous fistula. [7][8][9] However, for many patients, thrombectomy is incomplete, with early occurrence of rethrombosis. As a result, venous thrombectomy has not been accepted as the standard treatment for these patients.…”

Arteriovenous fistula geometry in hybrid recanalisation of post-thrombotic venous obstruction

“…Both 5-mm and 6-mm AVFs are assumedly sufficient to reach that point, which is consistent with previous research. 17 Since placing the PTFE in a loop or a straight did not influence results, it is apparently not relevant whether flow enters the vein in an antegrade or retrograde direction. Ostensibly, outflow of the lower limb does not seem to suffer under the initial different flow direction of the blood from the AVF.…”

Use of a Superficial Femoral Artery Autograft as a Femoral Vein Replacement

“…Usage of SFA as an autologous graft to reconstruct SFV makes it unnecessary to constitute an AVF as described in the literature to improve patency of venous reconstruction. 6 Utilization of the SFA as an autograft has been reported for popliteal aneurysm repair and carotid artery reconstruction in the absence of conventional venous conduits. 7,8 Ghosh et al 9 reported successful use of an SFA autograft as a femoral vein replacement on a 46-year-old-man during en bloc sarcoma resection.…”
