RIVERO RAPALINO, Oscar; BARRAGAN LEAL, Camilo; SALCEDO MIRANDA, Diego  y  QUINTERO ROJAS, Laura. Transcatheter venous coil embolization of gastric varices. Rev Col Gastroenterol [online]. 2019, vol.34, n.3, pp.307-313. ISSN 0120-9957.  https://doi.org/10.22516/25007440.251.

Coils and microcoils, the most commonly used embolization agents, have reported technical success rates ranging from 81% to 100% of cases. The spirals or coils are available in a wide variety of configurations and sizes which fit into vessels of different calibers. They have good radiopacity allowing for accurate release. Coils are the analogue of a surgical arterial ligation, because they produce mechanical occlusion due to their positioning in the vascular lumen. This decreases blood flow while their synthetic fibers have an additional thrombogenic effect.

Palabras clave : Digestive bleeding; gastric varices; embolization; coils.
