Successful Reablation Hemostasis for Needle Tract Bleeding Following Colorectal Liver Metastasis Percutaneous Microwave Ablation: A Case Report

Percutaneous ablation is a well-established alternative treatment for colorectal liver metastasis. Major complications after percutaneous ablation are less common but can occur. Few intervention options for immediate hemostasis after percutaneous ablation have been described, with most involving embolization or surgery. Recently, a few reports have shown good results of percutaneous heat ablation for hemostasis in needle tract bleeding. We report a case involving a 78-year-old woman who developed needle tract bleeding immediately after percutaneous microwave ablation for colorectal liver metastasis. The bleeding was successfully controlled using a reablation technique.
