description: 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.

Renal cell carcinoma treated with Cryoablation

2:09

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
