Inoperable 92 year old patient treated with Quality Ablation

MWA of three liver metastasis in segment II/III, IV and V/VIII for a patient that previously underwent acute surgery for a perforated tumor in the ascending colon and has now developed metastasis in the liver. Due to the age of the patient, a surgical solution was not an option, therefore Quality Ablation with CAS-One IR was chosen.

Name: Dr. Waldemar Czekierda

Institution: Linköping University Hospital

Patient age, sex:  92, Female

Initial condition:

  • Patient with a history of hypertonia, hyperlipidemia and hyperthyroidism
  • Underwent acute surgery for a perforated tumor in the ascending colon (T4aN1a) in October 2022
  • Recently three liver metastasis in segment II/III, IV and V/VIII were discovered
  • Due to the age of the patient, she was not eligible for another surgical treatment 
  • The multidisciplinary tumor board decided for a minimally invasive approach with MWA
  • Quality Ablation with CAS-One IR is the standardized treatment option for these patients in Linköping


  • The procedure was performed under general anesthesia with high-frequency jet-ventilation (HFJV) for optimal respiratory motion control
  • Three single-needle trajectories were planned, simulated and, navigated with the new interactive planning mode
  • The ablation of the lesions was performed with the Medtronic Emprint system (15 cm. antenna)
  • Needle placement control scans were performed for all three needles, with no manual repositioing needed
  • After treatment of all three lesions, the AI driven AblaSure confirmed that no additional ablation was needed


  • All three lesions were successfully treated with sufficient ablation margins between 5mm and 10mm as assessed by AblaSure.
  • The patient was discharged the following day and showed a swift recovery
  • A routine follow-up CT scan is planned within 3 months
