Clinical case

38-year-old female former smoker diagnosed with bronchial carcinoid tumour located in the lower lobe of the left lung.

3D anatomical model

Technology: FDM

Material: PLA

Resolución: 0.2 mm

Finish: Two colors

Surgical plan and results in operating room

The first surgical plan, based on the CT images, was a left lower lobectomy.

After having the 3D model of the patient's airways available, the surgeon was able to precisely locate the tumour and noticed that it was lower than he thought. In addition, the three-dimensional model made it easy to identify its boundaries, which allowed him to think of a new plan for the patient's treatment.

Thus, the surgical strategy was changed and a segmental bronchial resection was performed, which involved removing only the tumour while sparing the patient's lower lobe.

Reanastomosis of the bronchial tree was then performed to reconstruct the airway without loss of lung parenchyma.


Dr. Bertolloti

"What we were thinking and what our brain was projecting, based on the 2D images, was that the tumour was in a different position and really, this took us to the operating room with a totally different idea of what we could do."
