The effects of carotid artery stenting on short-term clinical outcomes and evaluation of restenosis
Journal Title: Dicle Tıp Dergisi - Year 2011, Vol 38, Issue 4
Abstract
Objectives: Data on restenosis and long-term outcomes of carotid stenting are limited. The aim of this study was to investigate cardiovascular effects of carotid stenting on clinical outcome and restenosis in patients with symptomatic severe carotid artery stenosis. Materials and methods: Twenty patients (mean age: 68±7 years, 11 male) who have been decided to perform stenting in joint Committee of Cardiology, Cardiovascular Surgery and Neurology Clinics were included.Patients were evaluated both clinically and Doppler ultrasonographically for frequency of cardiovascular events and restenosis. Restenosis is defined as the reapperance of stenosis with a diameter reduction of ≥%50 with peak systolic velocity higher than 224 cm/s. Results: Comorbidities in patients were; coronary artery disease in 14, peripheral artery disease in three, and both chronic renal failure and congestive heart failure in two. Stent diameters were ranged from 6 to 8 mm, and stent lengths were 30 and 40 mm. During the procedure 5 patients had predilatation and 19 had postdilatation. None of the patients had >%30 resudial stenosis after the procedure. All procedures were technically successful. After the procedure only one transient ischemic attack was seen. There were no restenosis, myocardial infarction, death or stroke at 30th day end of the first year of follow up. Diabetes and heart failure were found as predictors for restenosis. Conclusion: In highly selected cases, carotid artery stenting is an effective and safe method in the short term. Restenosis did not seem to be a restricting problem for the success of carotid artery stenting
