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.
