Paper Abstract

We used an excimer laser system (xenon-chloride at the wavelength of 308 nm) to treat totally occluded peripheral vessels in 71 patients. Energy was delivered through a multifiber catheter, which combines 12 (7F) or 18 (9F) fibers (260 (mu) diameter each), concentrically arranged. Balloon dilatation was associated to complete the procedure in 84% of the cases. The immediate success rate was 97%. The cumulative patency rate was 49% at one year. The major problems with this system were that the stiff multifiber tips caused dissections, and spasm; dead space/active space ratio of the catheter was unfavorable, allowing mechanical `dottering;' the maximum lumen obtained was considered inadequate. After this three year period, the goal of our clinical laser program is to develop a stand alone laser technique by employing a multifiber catheter which combines 130 - 150 fibers 100 (mu) diameter each, and features a quartz coated distal tip.
