Stenting Of The Superficial Femoral

Stenting of the Superficial Femoral and Popliteal arteries have become more commonplace over the last 2 decades. Performance of these stents has generally been determined by clinical patency and restenosis by external Doppler ultrasound and repeat angiography. Very little information exists regarding how these peripheral stents appear and perform immediately after deployment. Intravascular ultrasound (IVUS) has become a useful tool in the coronary anatomy to evaluate stents for adequate deployment and to evaluate the artery for hidden issues that may affect patency such as dissection Anecdotally; intravascular ultrasound has shown instances of significant external compression despite adequate initial expansion of traditional nitinol stents placed in the SFA and Popliteal arteries. This study supports the clinical observations that interwoven nitinol stents deploy consistently near their theoretical maximum with good resistance to external compression. The relative lack of deployment seen in the 6 mm cohort may be partially due to external forces but also is likely to be associated with the inability to dilate the vessel to an adequate size to allow full deployment atmospheres with the same size balloon as the stent in the predeployment inflation and using the same balloon in the post deployment saving one balloon each case. Anecdotally, the post IVUS sometimes shows vessels are not as large as the stent and are not going to dilate without substantial trauma. The sizing of the vessel is likely to be a major reason why the 6 mm stents did not perform quite as well as the 5mm stents in this study. The additional information provided by the RSSI calculation supports the observation that these stents deploy with consistent round lumens interwoven Nitinol stents perform well at implant with consistent SER across multiple stent sizes when used in the SFA and Popliteal arteries. The RSSI data showed they deployed with relatively round shapes and generally did not appear to suffer substantially from external compression. OMICS Group International is an open access online publishing group which has 700+ peer-reviewed journals, organizes 3000+ International Scientific Conferences per year, have around 50,000+ editorial board members and 1000+ Scientific associations. Medical Journals provide a platform for outstanding research around the globe in the field of medicine. These scholarly journals aim to contribute to the progress and application of scientific discoveries, by providing free access to the research information. The published work reaches the general public and the scientific community immediately after publication, thus providing higher citation rates for the author. Medical Journals are supported by 5000 internationally renowned editorial board members and a high quality review board. Medical Journals use online Editorial Manager System for quick and high quality review process. Articles of Medical journals are subjected to peer reviewing and these are included in the standard indexing databases like ISI, Scopus, EBSCO, CAS, HINARI etc. All the articles published in Medical journals are permanently archived in respective peer reviewed journals thus providing unrestricted utilization and requisition of the scientific information.
