Successful Percutaneous Intervention for Ostial Stenosis of Left Internal Mammary Arterial Graft

Abstract

Left internal mammary artery (LIMA) graft is the commonly preferred graft for bypass surgery and is particularly anastomosed to the left anterior descending artery. Stenosis of this graft frequently develops in the distal anastomosis site or within the distal native vessel after surgery, whereas it rarely develops in the ostial site. The pathophysiology of stenosis in the ostial site remains unclear. Percutaneous stenting of ostial lesions has rarely been reported in literature. We believe that such percutaneous transluminal stenting is appropriate for ostial lesions of LIMA grafts.

Sol İnternal Mammarian Arter Ostial Darlığına Başarılı Perkütan Girişim

Abstract

Sol internal mammarian arter (LİMA) baypas cerrahisinde genelde tercih edilen grefttir ve özellikle sol ön inen artere anastomoz edilir. Bu greftin operasyon sonrası daralması genelde distal anatomoz bölgesinde veya distal nativ damarda meydana gelir. LİMA greftinde nadiren ostial bölgede daralma gelişir ve bu durumun patofizyolojisi halen net değildir. LİMA ostial lezyonunun perkütan stentleme ile tedavisi literatürde nadir olarak bildirilmiştir. Belirttiğimiz yöntemle LİMA greftinin ostial darlığının stent ile tedavisinin bu durum için en uygun tedavi yöntemi olduğunu düşünmekteyiz.
