Abstract

Objective. In this study, we evaluated the utility of 16-slice MDCT (multidetector computed tomography) to assess stent patency after coronary artery stenting. Materials and Methods. Retrospective ECG-gated CT-angiography using 16-slice MDCT was performed in 52 consecutive patients with coronary artery stents. Qualitative assessment of 61 coronary stent lumens by MDCT is reported, and the reasons preventing assessment were investigated.Results. All non-assessable stents were non-assessable due to partial volume effects and metal artifacts. To evaluate instent restenosis, conventional coronary angiography was performed on the 54 assessable stents in 48 patients, and the results were compared with the MDCT results. Based on the results of the conventional coronary angiography, MDCT correctly detected four in-stent restenosis.Conclusion. Despite some limitations, 16-slice MDCT provides sufficient evaluations of some coronary stents, and can detect in-stent restenosis with high accuracy.

Özet

Amaç. Bu çalışmada koroner arter stentlerinde 16 kesitli bilgisayarlı tomografinin (BT) stent içi lümeni değerlendirmedeki rolünü inceledik. Gereç ve Yöntem. Koroner arter stenti yerleştirilmiş sıralı 52 hasta (61 stent), retrospektif elektrokardiyografi (EKG) kapılı BT anjiyografi ile incelendi. Altmış bir stentin lümenlerinin çok kesitli bilgisayarlı tomografi (ÇKBT) ile değerlendirilebilirliği nitel olarak gözden geçirildi ve değerlendirilemez görüntülerin sebepleri araştırıldı. Bulgular. Değerlendirilemez görüntülere kısmi hacim etkileri ve metal artefaktları neden olmuştu. Ayrıca stent içi restenoz açısından değerlendirilebilir görüntülere sahip 48 hastadaki 54 stent, konvansiyonel koroner anjiyografi ile tetkik edilerek sonuçlar karşılaştırıldı. Konvansiyonel koroner anjiyografi ile karşılaştırıldığında ÇKBT koroner anjiyografi 4 stentte stent içi restenozu doğru bir şekilde tanıyabilmişti. Sonuç. Bazı sınırlılıklarına rağmen 16 kesitli bilgisayarlı tomografi koroner arter stentlerinin incelenmesinde yeterince yararlı bir yöntemdir. ÇKBT değerlendirilebilir görüntüler elde edildiğinde konvansiyonel koroner anjiyografi ile karşılaştırılabilir düzeyde yüksek doğruluğa sahip sonuçlar verebilmektedir.
