ABSTRACT
The formation of an aneurysm in the aorta or pulmonary artery is a dangerous potential complication of surgical and angioplasty procedures involving these vessels. Treatment using covered stents has emerged as an effective alternative to surgery and the use of conventional stents. The authors report on 2 patients who were treated successfully by the implantation of covered stents in the aorta and pulmonary artery following angioplasty and surgery, respectively. We discuss the mechanisms of aneurysm formation and the efficacy and limitations of using covered stents in such patients.

Una de las complicaciones más temidas del tratamiento quirúrgico o intervencionista de la coartación aórtica y de cualquier angioplastia sobre las ramas pulmonares esla aparición de un aneurisma. Los stents recubiertos han surgido como una efectiva alternativa terapéutica. Exponemos 2 casos de aneurismas en la coartación de la aorta y en la arteria pulmonar que fueron tratados efectivamente con stents recubiertos. Realizamos un comentario acerca de la formación de aneurismas y de la eficacia y las limitaciones del tratamiento con stents recubiertos
