Further Developments:Peripheral Stent v BypassRecognition Endovascular more attractive than bypass:• Improved patency with self expanding stents• Better than Balloon Angioplasty (PTA) alone in more severedisease• Worse than surgical bypass in more severe disease!• Does not preclude surgery later…Trend to treat with stents and if fail, bypass in less severe disease.
<strong>Spiral</strong> <strong>Flow</strong> Stent• How well do peripheral vascular stentswork?2 year patency (bare stents) range:• 80% Iliac ( Pelvis)• 65% Femoro-popliteal (Thigh)• 30-40% Infra-popliteal (Calf)• Why does the treatment fail?
