[Transcatheter embolization device as a promising option in the treatment of pulmonary sequestration. Case reports]

Pulmonary sequestration (PS) has been treated for many years with conventional surgical removal of the ectopic lung tissue and ligation of aberrant vessels that arise from the aorta. There is evidence, especially in English-language literature that supports the use of transcatheter arterial embolization through a device for occlusion of the anomalous vessel, as a safe option and definitive treatment for intralobar PS.

To show our experience pioneering the technique of PS treatment through transcatheter embolization.

The case reports of two teenagers aged 13 and 14 and a 26-day-old newborn that developed intralobar PS are described. The diagnosis was made through computerized axial tomography (CT scan) and successfully and without complication, during early and long term follow-up, treated by arterial embolization transcatheter.

The use of transcatheter arterial embolization is a less invasive and definitive treatment for patients with PS.
