As technology improves , MDCT may be considered as a valuable alternative method to conventional angiography to evaluate stent patency and in-stent restenosis.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Purpose: Comparison of multidedector computed tomography (MDCT) and color Doppler ultrasound (USG) findings for evaluating the stent patency in the patients that have aorta iliac stents.Materials and Method: Thirty patients (two female(6.6 %) and 28 male (93.4 %) ) who had stent implantation due to aorta iliac lesions were enrouted . 3-43 months after stent implantation stent patency was evalueted with color Doppler USG and MDCT.Result: Total fourty stent that implanted to thirty patients were enrouted.
📊
Key Findings & Data:Seventeen stents located in the right iliac arteries , twelve stents located in the left iliac arteries and six stents located in right external iliac arteries, five stents located in left external iliac arteries. 38 stents in 28 patients were evaluated by color Doppler USG..

Abstract

Purpose: Comparison of multidedector computed tomography (MDCT) and color Doppler ultrasound (USG) findings for evaluating the stent patency in the patients that have aorta iliac stents.Materials and Method: Thirty patients (two female(6.6 %) and 28 male (93.4 %) ) who had stent implantation due to aorta iliac lesions were enrouted . 3-43 months after stent implantation stent patency was evalueted with color Doppler USG and MDCT.Result: Total fourty stent that implanted to thirty patients were enrouted. Seventeen stents located in the right iliac arteries , twelve stents located in the left iliac arteries and six stents located in right external iliac arteries, five stents located in left external iliac arteries. 38 stents in 28 patients were evaluated by color Doppler USG.. Sensitivity and spesifity was detected %95 and %100. Stent patency in all patients evaluated by MDCT; in 9 patients initimal hyperplasia that is not caused significant stenosisestablished by reconstruction images. Conclusion: Use of noninvazive methods like MDCT and color Doppler USG allows very accurate evaluation of stent patency to be compared with an invazive method conventional angiography. As technology improves , MDCT may be considered as a valuable alternative method to conventional angiography to evaluate stent patency and in-stent restenosis.

Özet

Amaç: Aorta ilyak stent uygulanan hastalarda stent patensisinin değerlendirilmesinde çok kesitli bilgisayarlı tomografi ve renkli Doppler ultrasonografi bulgularının karşılaştırılması. Materyal ve Metod: Aorta ilyak lezyon nedeni ile stent uygulanan, 2’si kadın (%6.6), 28’i erkek (%93.4), yaşları 34-78 (ortalama 56.4±21.2 yıl) arasında değişen 30 olgu çalışmaya alındı. Stent tedavisini takiben 3-43 ay (ortalama 18±0.25 ay) sonra renkli Doppler ultrasonografi (RDUS) ve çok kesitli bilgisayarlı tomografi (ÇKBT) ile stent patensisi değerlendirildi. ÇKBT değerlendirmede aksiyel, koronal, multiplanar reformat (MPR), curved planar reformat (CPR) görüntüler oluşturularak patensi değerlendirildi. Bulgular karşılaştırıldı. Bulgular: Toplam 30 olguya uygulanmış 40 stent değerlendirmeye alındı. Stentlerin 17’si (%42.5) sağ ana ilyak arter, 12’si (%30) sol ana ilyak arter, 6’sı (%15) sağ eksternal ilyak arter, 5’i (%12.5) sol eksternal ilyak arterde lokalizeydi. RDUS ile 28 olguda 38 stent patensisi gösterilebildi. Sensivite %95, spesifisite %100 olarak saptandı. ÇKBT ile tüm olgularda stent patensisi gösterildi. Rekonstrüksiyon görüntülerde 9 (%22.5) olguda anlamlı stenoza neden olmayan intimal hiperplazi saptandı.Sonuç: Stent patensisinin takibinde görece invaziv bir metod olan konvansiyonel anjiografiye göre, ÇKBT ve RDUS gibi noninvaziv görüntüleme metodları etkin ve güvenilir biçimde kullanılabilir. Gelişenteknoloji ile ÇKBT, çözümlenmemiş bir sorun olan intimal hiperplazinin görüntülenmesinde alternatif bir tanı metodu olabilir.
