Geçirilmiş baypas cerrahisinin perkütan koroner girişim sonuçları üzerine olan etkisi / geçirilmiş koroner arter baypas cerrahisi sonrasında yapılan perkütan koroner girişimleri güçleştirir mi?

Amaç: Koroner arter hastalığında modern tedavi seçeneklerine rağmen tekrarlayan revaskülarizasyon sıklıkla gerekir. Tekrarlayan revaskülarizasyon, koroner baypas cerrahisi (KABC) geçirenlerde özel dikkat gerektirir. Önceki KABC’nin perkütan koroner girişimler (PKG) üzerindeki olası yan etkilerini araştırmak için yapılmış çok az sayıda çalışma mevcuttur. Bu çalışmada, koroner baypaslı hastaların PKG sonuçları araştırıldı. Yöntem: PKG uygulanan tüm hastalar retrospektif olarak tarandı. Daha önce PKG öyküsü olan ardışık 100 hasta (1. grup) ile önceden KABC öyküsü olan 100 hasta ( 2. grup) çalışmaya dahil edildi. Tam oklüde ve ya stent içi lezyona ya da baypas grefte uygulanmış PKG ile ST elevasyonlu miyokardiyal infarktüs nedeniyle başvuran veya bifurkasyon stentleme uygulanan hastalar çalışmaya dahil edilmedi. Bulgular: Yaş ve cinsiyet açısından 1. ve 2. grup benzerdi. Diğer demografik özellikler açısından da istatistiksel olarak anlamlı fark yoktu. Lezyon ağırlığı da iki grup arasında anlamlı derecede farklı değildi. KABC grubunda sirkumfleks arter lezyonuna girişim daha sıkken, PKG grubunda sol ön inen arter lezyonuna girişim sıktı. Her iki grupta prosedürü zorlaştıran faktörler benzerdi. Her iki grup arasında 20 mm’den uzun lezyon varlığı ve diffüz koroner arter hastalığı açısından anlamlı fark yoktu. KABC grubunda balon ve stentleme daha sıkken, PKG grubunda direkt stentleme daha sıktı (p

The effect of undergone bypass surgery on the percutaneous coronary intervention results / does previous coronary artery bypass surgery complicate the subsequent percutaneous coronary intervention?

Objective: Recurrent revascularization is frequently needed in despite to the modern treatment options of coronaryartery disease. Recurrent revascularization has need special caution in the setting of previous coronary artery bypasssurgery (CABG). There are very few studies to investigate possible adverse effects of prior CABG on percutaneouscoronary interventions (PCI). This study investigated that PCI results of the patients with prior CABG.Method: Patients who underwent PCI screened retrospectively. Consecutive 100 patients had been prior PCI (group 1),and 100 patients had been prior CABG (group 2) were enrolled to the study. The patients were not enrolled in the study;index PCI underwent bypass graft or total occluded lesion or instant lesion or in the setting of ST elevation myocardialinfarction or bifurcation stenting was done.Results: Group 1 and group 2 were similar in terms of age and gender. No statistically significant difference wasobserved between other demographic features. The lesion severity was not significantly different between the groups. Inthe CABG group, the intervention was more frequent to the circumflex artery lesion; while in the PCI group,intervention to the left anterior descending artery lesion was more frequent. Factors that made the procedure difficultwere similar in both groups. There was no significant difference between the two groups regarding lesions longer than20 mm and diffuse coronary artery disease. Balloon and stenting were more frequent in the CABG group, and directstenting was more frequent in the PCI group (p
