ABSTRACT

Describimos el caso de dos pacientes que durante la angioplastia los stents se desprendieron del balón sin expandir y quedaron atrapados en el árbol coronario. En un paciente el stent quedó enclavado en la curvatura de la arteria circunfleja y en el otro paciente en el tronco común distal. Los stents se extrajeron en el primer caso tras avanzar un balón de bajo perfil a través del stent y en el otro tras colocar otra guía exterior al stent y situar un balón distal. En ambos casos se hinchó el balón distal a los stents y se logró desenclavar al retirar el balón hacia el catéter guía y después todo el sistema.


We describe two patients in whom stents dislodged from the unexpanded balloon during angioplasty and remained trapped in the coronary tree. In one patient the stent was located in the curvature of the circumflex artery and, in the other patient, it was detected in the distal left main artery. Retrieval of the undeployed stents was accomplished in the first case after advancing a low profile balloon through the stent and, in the second case, after placing a second guidewire exterior to the stent. In both cases, the balloon was inflated distally and the stents were dislodged after pulling the balloon back towards the guiding catheter and then withdrawing the whole system.
