Navigated Microwave Ablation of a Colon Metastasis in the Lung
Navigated microwave ablation of a metastasis of the colon that has settled in the lower left lobe of the lung. Planning of the procedure, ablation and verification with CAS-One IR. The CT control scan taken three months after surgery shows no signs of local tumor activity.

- CT thorax/abdomen/pelvis (02/2019): Slight increase in size of the known intrapulmonary round foci in the left upper lobe dorsobasal and lower lobe dorsobasal. Subcapsular hematoma in liver segment VI, constant in size compared to the previous examination. No evidence of newly occurring liver metastases
- Uniportal, anatomical segment VI resection and radical mediastinal lymphadenectomy left with pulmonary metastasis in the apical lower lobe on the left
- Navigated microwave ablation of a colon metastasis in the lower left lobe of the lung
- The control CT three months after treatment shows no tumor activity
