Clinical case

A 45-year-old man was diagnosed with a right upper lobe lung tumour. The tumour invaded the chest wall and the indicated treatment was resective surgery after chemotherapy and neoadjuvant radiotherapy.

For the planning of the surgery, a customised anatomical model of the patient was used to replicate the full-scale anatomy.

3D anatomical model

◾ FDM Technology

◾ Material: PLA

◾ Resolution: 0.2 mm

◾ Finish: Multiple colours

Surgical planning and outcomes in the operating room

Dr. Nicolás had a virtual and a physical 3D model that allowed him to clarify all the doubts about the anatomy and the extent of the anomalous mass that the two-dimensional images could not resolve. This gave him the possibility to optimise the resection margins.

The mini-invasive surgical plan chosen was a right upper lobectomy by uniportal video-assisted thoracoscopic surgery (UVATS) with rib resection. The physical biomodel was useful to visualise and project how the selected procedure would be performed for the patient.

"The model allowed me to better evaluate the case and define the resection margins, narrowing them and allowing for a more economical surgery."

The 3D anatomical model was also used in the operating room, which was consulted several times to guide the approach to the tumour and was fundamental to recognise the repair points on the rib that delimited the resection, Dr Nicolás said.

In addition, the doctor used the 3D models to explain the surgery to the patient, showing him greater commitment and expertise in the case and thus transmitting security and peace of mind.

The surgery was successfully performed in 280 minutes and the patient showed a rapid and very favourable evolution.
