Female patient with a history of breast cancer had a 39mm renal cell carcioma. Due to ongoing chemotherapy, cryoablation with the assistance of CAS-One IR was decided as opposed to a partial nephrectomy. Three cryoablation probes were planned, simulated and navigated to successfully cover and ablate the lesion. No complications were observed and the patient awaits a 3-month follow-up.

Name: Dr. Gerhard Gruber
Institution: Barmherzige Brüder, Vienna
Patient age and sex: Female, 68y
Initial condition:
- Patient initially diagnosed with breast cancer in December 2023
- A CT scan discovered a renal cell carcinoma T1a of 39mm
- Different approaches to treat the kidney lesion was discussed at the MDT meeting
- Due to her breast neoplasia currently being treated with chemotherapy, cryoablation was preferred over a partial nephrectomy
Treatment:
- Procedure was performed under general anesthesia
- The lesion was visible on CT and a three needle cryoablation treatment was planned and simulated to cover the tumor
- Cryoablation was performed with three IceRod probes (Boston Scientific)
- Due to the patients anatomy finding a safe trajectory was challenging, but with the help of MPR view and 3D models a safe trajectory was planned and executed
- All three needles were placed with a accuracy of less than 3mm lateral error
Result:
- The lesion was successfully treated and iceballs were evaluated on post-ablation scans
- The patient stayed as an in-patient after the procedure, upon own request, although no complications occurred
- A 3-month follow up CT and renal function tests are planned
