Abstract

To determine long-term patency of femoropopliteal artery percutaneous transluminal angioplasty (PTA) in a prospective trial during which prolonged balloon inflation was used for optimization of initial results. Femoropopliteal PTA was performed in 112 limbs of 97 patients. The mean total length of the treated segments was 7.2 cm (95% CI: 5.99-8.46; median: 5.5 cm). In cases of unsatisfactory primary results after standard dilation for 1-3 minutes, the procedure was continued with prolonged dilation (93 limbs; mean balloon inflation time: 31 min; 95% CI: 24.2-37.7; median: 15 min) with use of the same balloon catheter (77 limbs) or a perfusion balloon catheter (35 limbs). Thirty-four proximal infrapopliteal artery stenoses were treated to improve peripheral runoff and 12 short stents were placed because of flow-limiting dissections. Primary hemodynamic success established by Doppler ultrasound (US) criteria was achieved in 92.9% (104 of 112) of the limbs. Three major complications were encountered; none were related to prolonged balloon inflation. The primary patency rate according to Kaplan-Meier analysis was 42% (+/-5% SE) at 1 year and 39% (+/-5%) at 2 and 3 years. The corresponding secondary patency rates were 51% (+/-5%) an...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
