Complex percutaeous intervention with six needles and long trajectories. Cryoablation of a renal cell carcinoma close to pancreatic tail and spleen. CT-guidance and CAS-One IR allowed a very precise placement of all six needles and in result a complete ablation of the entire tumour.
Name: Prof. Dr. Tze Wah & Dr. Jon Smith
Institution: St. James's Hospital, Leeds, United Kingdom
Patient age and sex: 67 years, male
Initial condition:
- The patient is an ex-smoker with a history of IHD, obesity, COPD, claudication
- Had a femoral stent inserted 17 years ago
- This is a co-morbid patient, not fit for surgery
- Patient presents with a 4.2cm Renal Cell Carcinoma, close to pancreatic tail and spleen
- Upon arrival, an ASA Physical Status Classification of 3 was recorded
-
6 ICE force probe needles (18cm trajectories) were planned using CAS-One IR. Additionally, a tumour biopsy was performed. Once inserted, needle validation showed that needles 1-4 had a lateral error of 2mm and needle 5-6 had a lateral error of 6mm. The 6mm lateral error was due to the difficulty in inserting needles because of needle crowding
Result:
- This was considered a complex case as the tumour was in close proximation to spleen and pancreas. However, overall needle planning and insertion was facilitated using CAS-One IR
