Above and below knee femoropopliteal VIABAHN^®

Abstract

VIABAHN® stent grafts have a significantly lower clinical patency and higher rates of amputation when they extend across the knee joint.

Jetstream XC Device for Treatment of Long Viabahn Stents Occlusions in the Superficial Femoral Artery: A Report of Two Cases

“…More recently however, there are growing concerns over the high rates of thrombosis (16–34%), which can often lead to acute limb ischemia and require urgent revascularization. 5 ) Several trials have demonstrated that catheter-directed thrombolysis techniques are non-inferior to open surgical strategies with respect to acute limb salvage, and that catheter-directed thrombolysis in graft cases can be more effective than in native vessels. 6 ) However, the use of catheter-directed thrombolysis has also been associated with higher rates of distal embolization and bleeding.…”

Long-term results of the heparin-bonded Viabahn stent graft in femoropopliteal TASC C and D lesions with a covered stent length of minimum 25 cm

“…Small stent diameter and stent placement below the femoral condyles are factors of a decreased patency. 4,13 The Viabahn 25-cm trial showed a satisfactory one year primary patency. 5 However, long-term results regarding a covered stent length with 25 cm and more are missing so far.…”

“…Multiple studies and randomized trials have been published in the last years regarding the heparin-bonded Viabahn (W.L.Gore & Associates, Flagstaff, Ariz) stent graft. [4][5][6][7][8][9][10][11][12] Most of these reports present one or two years results. Small stent diameter and stent placement below the femoral condyles are factors of a decreased patency.…”

“…Los nuevos dispositivos diseñados específi camente para este sector como el stent mimético, se presentan además como una herramienta útil frente al fracaso del balón 162 . 165 . La misma considera una combinación de juicio clínico con la interpretación cuidadosa de evaluaciones objetivas de la perfusión, las características morfológicas de la herida y la infección (Figura 4), la cual es necesaria para seleccionar adecuadamente a los pacientes para revascularización o con mayor posibilidad de amputación.…”
