Acute Lower Gastrointestinal Bleeding

Abstract: The annual incidence of lower gastrointestinal bleeding (LGIB) is ∼20.5 in 100,000 in the general Western population and results in 1 to 2% of hospital emergencies. When medical management and endoscopic therapy are inadequate in cases of acute LGIB, endovascular intervention can be lifesaving. In these emergent situations it is important for the interventional radiologist to be well versed in the multidisciplinary preangiographic work-up, the angiographic presentations of LGIB, and the endovascular therapeuti… Show more

“…Koil embolizasyonu mümkün olmayan tortüöz seyirli vasküler yapılarda glue gibi sıvı embolizan ajanlar kullanılabilir. Bu ajanlar koillerin verilemediği 0.010 inch'ten küçük mikrokateterlerden rahatlıkla uygulanabilir (2). Glue ile yapılan embolizasyonda işlem süresi daha kısadır.…”

“…Cerrahi müdahale ile karşılaştırıldığında arteriyel embolizasyonun hastanın hızlı iyileşmesi, erken taburcu olması ve fiziksel aktivitelerine erken başlaması gibi avantajları bulunmaktadır (1). Üst gastrointestinal sistem (GİS), alt GİS, pulmoner ve travmatik nedenli hayatı tehdit eden arteriyel kanamalarda selektif endovasküler arteriyel embolizasyon yapılabilmektedir (2)(3)(4)(5)(6)(7). Embolizasyon sırasında embolizan ajanların seçimi vasküler anatomiye, anjiografik bulgulara, kateterin pozisyonuna ve kullanıcı tercihine bağlı değişebilmektedir (8).…”

“…Los espirales o coils se encuentran disponibles en una amplia variedad de configuraciones y tamaños, lo que permite acomodarse a vasos de distintos calibres, y por su buena radiopacidad, tienen la ventaja de ser liberados con precisión. Los espirales o coils son el análogo de una ligadura arterial quirúrgica, debido a que producen una oclusión mecánica por su posicionamiento en el lumen vascular, lo que disminuye el flujo sanguíneo, y sus fibras sintéticas tienen un efecto trombogénico adicional (1,5,6).…”
