Embolization does occur with laser photoablation in the lower extremity, but the rate of clinically significant macrodebris is low ( approximately 20%) and similar to that found after angioplasty and stenting. Embolic filter protection appears to be very effective in capturing macrodebris, and its use is associated with good acute angiographic outcome. Problems with filter retrieval were not encountered.
JetStream atherectomy using the XC device has favorable acute results in treating femoropopliteal ISR with high procedure success, no device-stent interaction, and favorably low TLR rates. A multicenter trial is needed to confirm these results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
