Abstract

The Relationship Between the patterns of in stent restenosis and stent type, stent diameter and length of the stent. The reasons for differences among locations of the neointimal proliferative • response to implanted stents are unknown. Intrinsic patient related factors and design of the stent seem to be responsible for different patterns of in-stent restenosis (ISR). The angiographic presentation of ISR may provide prognostic information on subsequent target vessel revascularization. The aim of this study was to investigate the relationship between the patterns of ISR and stent type, stent diameter and length of the stent. Seventy two ISR patients were inclu-ded in this study. ISR was angiographically defined as more than 50% narrowing in the stented segment. The patterns of ISR have been categorised as follows: focal (pattern I), diffuse proliferative (pattern II) and total occlusive (pattern III). Two different types of stent were compa-red: Coil (Cook stent) (n= 41) and tubular (NIR stent) (n= 31). Pattern I was found in 37% of patients (n=27), pattern II in 51% (n=37) and pattern III in 11% (n=8). In the coil-stent group, pattern I presented 34% of restenotic lesions, pattern II 56% and pattern III 10%. In the tubular-stent group, pattern I presented 41% of restenotic lesions, pattern II 45% and III 13%. Although coil-stent group tends to be more frequently presented with pattern II, this was not statistically significant. But there was a statistically significant correlation between the diame-ter and length of the stent and the patterns of ISR (p

Özet

İmplante edilmiş stente karşı gelişen neointimal proliferasyonun stent içi lokalizasyonundaki farklılıklara yol açan faktörler net olarak bilinmemektedir. Stent içi restenozunun (SR) farklı patternlerde ortaya çıkmasından sorumlu olan faktörler arasında stente ait özellikler de (stent dizaynı, boyu, çapı) yer alabilir. SR'nun anjiyografik presentasyon şekli sonraki girişimsel teda-vi yönteminin türü hakkında da yol gösterici olabilir. Bu çalışmanın amacı SR'nun paterni ile stent dizaynı, çapı ve uzunluğu arasındaki ilişkinin araştırılmasıdır. Bu çalışmaya SR olan 72 hasta (72 lezyon) dahil edildi. SR anjiyografik olarak, 6 ay sonra yapılmış olan kontrol anjiyografide stent içerisinde > %50 darlık olması şeklinde tanımlandı. SR paternleri şu şekilde sınıflandırıldı: tip I: "Fokal" SR: stent içi, proksimal veya distal uçta veya eklem bölgesinde ve uzunluğu 10 mm olan restenötik lezyon, tip III : "total oklüzyon": TİMİ (thrornbolysis in myocardial infarction) O derecede akımı olan lezyon. İki farklı tip stent karşılaştırıldı: Kıvrımlı stent (n=41) ve tubuler stent (n=31). Hastaların %37'sinde (n=27) tip I, %51'inde (n=37) tip II ve %11'inde (n= 8) tip III SR tespit edildi. Kıv-rımlı stent grubundaki restenötik lezyonların %34'ünde tip I, %56'smda tip II ve %10'nunda tip III SR saptandı. Tubuler stent grubunda tip I %41 sıklıkla, tip II %45 sıklıkla ve tip III SR % 13 sıklıkla tespit edildi. Kıvrımlı stentlerde daha çok diffüz tipte (tip II) SR eğilimi saptanmak ile birlikte bu farklılık istatistikl olarak anlamlı bulunmadı (p=0.07). Fakat stent .boyu ve çapı ile SR'nun tipi arasındaki ilişkiler anlamlıydı (sırasıyla, p
