Percutaneous Cryoablation of Metastatic Lesions from Colorectal Cancer: Efficacy and Feasibility with Survival and Cost-Effectiveness Observations
Figure 1
61-year-old male with metastatic colon cancer status after multiple RF and hepatic cryoablations as well as prior pulmonary cryoablations due to refusal to consider systemic chemotherapy presents for cryoablation of a growing satellite focus in the left lung at a previous ablation site. Axial CT images (from left to right) demonstrate the growing satellite focus (single arrow) measuring cm which was thoroughly ablated using three cryoprobes in a triple freeze cycle. The ablation zone measured cm which later resorbed to a nonenhancing ablation site measuring cm.
