Clinical Case

3D Model of a Large Left Renal Tumour | Cella Medical Solutions

We present the case of a 45-year-old male patient with no relevant medical history, diagnosed with a large left renal tumour associated with a tumour thrombus, classified as Neves grade III and Mayo level IIIA.

Surgical Planning

 

In this case, detailed analysis of the patient-specific 3D model was essential to accurately assess the anatomical axes of the structures involved and the tumour’s relationship with them. The analysis revealed marked dilatation of the right renal vein due to the presence of a tumour thrombus extending to the heart, a critical factor to be considered during surgical planning. Given these findings, venous flow diversion using an ECMO system was required to exclude suprahepatic caval flow from the retrohepatic inferior vena cava segment involved by the tumour.

Thanks to the precise visualisation provided by the 3D model, the multidisciplinary team at Hospital Universitario de la Ribera (Valencia)—comprising Dr López and Dr Véliz (Urological Surgery), Dr Margarit (Cardiac Surgery), and Dr Sala and Dr Poves (Hepatic Surgery) was able to strategically plan the optimal surgical access and the most appropriate operative approach for this highly complex intervention.

Surgical Outcome

The procedure was completed successfully, reflecting a high level of precision, planning and intraoperative safety. The use of 3D-assisted planning made it possible to reduce operative time by half, completing the surgery in just four hours, while achieving complete tumour resection and treatment of the tumour thrombus.
