Thoracic lipoma exeresis: virtual planning combined with 3D biomodelling

Dr. Rodrigo Pacheco Ruiz

Instituto Oncológico Nacional (CPS) - La Paz, Bolivia


Better understanding of the tumour and its relationship to adjacent structures.

Design of the surgical plan

Reduction of bleeding

Guidance in the surgical approach in the operating theatre

Improved patient-physician interaction

Improved communication within the surgical team

Clinical case

An adult male patient presented with a mass located in the left upper thorax. It generated compression causing pain and paraesthesia in the left arm.

CT scans revealed a progressively growing tumour.

Surgical plan and results in operating room

The treatment planning for this patient was performed with the physical 3D model and was complemented with the virtual anatomical model. The case was an exeresis of a chest wall lipoma located in the upper left vertex.

The clarity of the 3D model allowed a detailed analysis of the case and thus improved and optimised the approach and planning of the surgery, thinking in advance about the different surgical technique options and the possible eventualities of complications. In this way, additional material was prepared in case of intraoperative modification.

At the Fiorito Hospital, Dr. Ezequiel Muiño performed the planning with 3D models and resulted in a change of the original planning minimising the invasiveness of the intervention.

The 4 points highlighted by Dr. Pacheco after his experience with 3D planning:

1. It allows to improve the surgical planning, as it is in real size, the compression of the scope to be sectioned, and to anticipate possible vascular complications.

2. It collaborates with the preparation of progressive material to be used in cases of chest wall defects.

3. Facilitates planning and communication with the multidisciplinary surgical team.

4. Improves interaction with the patient and the patient's understanding of the true extent of their pathology.
