İntrakraniyal Arter Darlıklarının Endovasküler Tedavisinin Kısa ve Uzun Dönem Takip Sonuçları

Abstract

Intacranial artery stenosis is one of the most common causes of stroke. Intracranial artery stenosis can be treated with medical or endovascular therapy. Endovascular treatment is the only solution at the present time for the patients who are symptomatic despite medical therapy. The aim of the study was to retrospectively evaluate the safety and efficacy, the short and long-term angiographic outcomes of stent placement for intracranial artery stenosis in a single center. Sixty-one patients with 68 lesions were treated with stenting between June 2005 and February 2012. The average age of the patients was 62.9. All the patients but one were symptomatic prior to the procedures. The degree of stenosis were %50-70 in 6 lesions (%8.8), %70-90 in 25 lesions (%36.8) and greater than %90 in 37 lesions (%54.4) prior to treatment. Thirty-three lesions (%48.5) were located in the anterior and 35 lesions (%51.5) were in the posterior circulation. Stenting was performed successfully in all lesions. Of the 68 stents used in this study, 16 were balloon-expandable and 52 were self-expandable. There were 53 follow-up angiographic results of total 68 stents (%77.9) with an average follow-up time of 13.7 months (2-72 months). The restenosis rate was found to be %8.3 (1/12) for the balloon-expandable stents and %9.7 (4/41) for the self-expandable stents. Overall restenosis rate in this study was %9.4 (5/53). There were 2 asymptomatic stent occlusion and overall 5 major complication including mortality in this study. Endovascular treatment of intracranial artery stenosis with balloon-expandable or self-expandable stenting is a feasible, safe and effective method; short-and long-term results of treatment with this technique also reveal a high stability.
