Clinical studyThe TransAtlantic InterSociety Consensus (TASC) Classification System in Iliac Arterial Stent Placement: Long-term Patency and Clinical Limitations
Section snippets
Patient Population and Stratification
Our institutional review board approved a research subject review board exemption under secondary use of preexisting data in a retrospective method. Between October 1994 and December 2004, a retrospective review was performed of medical records at the Samsung Medical Center; 302 patients had undergone stent placement for chronic iliac arterial disease. Patients in whom no follow-up data were available (n = 79) were excluded from the study due to statistical insufficiency. Patients with
Results
The immediate technical success rate was 98% (260 of 264 limbs). Two hundred ninety-five stents were placed in 260 limbs of 215 patients; a single limb was treated in 170 patients (79%), and bilateral stent placement was performed in 45 patients (21%). The balloon-expandable stents used included the original Palmaz, Palmaz Corinthian, Palmaz Genesis stents (Cordis Europa, Roden, the Netherlands), and the Express LD stent (Boston Scientific, Boston, Mass). The self-expandable stents used
Discussion
Endovascular management of iliac arterial disease is a well-established approach for obtaining and maintaining long-term vessel patency with low mortality. An increasing number of patients with symptomatic iliac lesions and hemodynamically significant stenosis or occlusion prefer endovascular treatment. Indications for iliac arterial stent placement are composed of many guidelines and criteria associated with clinical evaluation of the patient. It has been difficult to establish morphologic
