Article information

Los aneurismas de la arteria pulmonar son poco frecuentes en niños. Entre sus principales causas se encuentran procesos infecciosos como la endocarditis, que favorece el desarrollo de aneurismas micóticos, en especial en pacientes con defectos cardíacos congénitos y en aquellos con adicción a drogas de uso endovenoso (sobre todo en adultos), y lleva al desarrollo de aneurismas micóticos. Las opciones de tratamiento dependen de las características de la lesión y de la condición clínica del paciente.

Se presenta el caso de una paciente de siete años, quien fue referida para evaluación por endocarditis infecciosa de la válvula tricúspide debida a Staphylococcus aureus. Desarrolló aneurismas bilaterales en ramas lobulares de la arteria pulmonar secundarios a la infección valvular. El aneurisma del lado derecho era de gran tamaño y con alto riesgo de ruptura, razón de peso para que se le efectuara embolización con coils. El procedimiento fue exitoso y no se documentaron complicaciones. La lesión del lado izquierdo se trató de forma expectante teniendo en cuenta que era de menor tamaño. En la actualidad la paciente está en seguimiento ambulatorio con el fin de vigilar la evolución del aneurisma del lado izquierdo.

Pulmonary artery aneurysms are infrequent in children. Among its main causes are infectious processes such as endocarditis which favors the development of mycotic aneurysms especially in patients with congenital heart defects and in those with endovenous drug addiction (mainly in adults) that develop mycotic aneurysms. Treatment options depend on the characteristics of the lesion and the clinical condition of the patient.

We present the case of a seven year old female patient who was referred for evaluation of infectious endocarditis of the tricuspid valve due to Staphylococcus aureus. She developed bilateral aneurysms in lobular branches of the pulmonary artery secondary to the valve infection. The right aneurysm was large and had a high risk of rupture, and for this reason an embolization with coils was performed. The procedure was successful and no complications were documented. Given that the left side lesion was smaller, it received an expectant management. At present, the patient has ambulatory follow-up in order to monitor the evolution of the left side aneurysm.
