CT-Guided Liver Hepatocellular Carcinoma Ablation with Cascination CAS-One IR

Liver cancer CT-guided ablation for 2 superior hepatocellular carcinomas (HCC) within the liver dome. With a history of chronic liver disease, this patient was found to have a two arterially hyperenhancing lesions exhibiting washout, in keeping with HCC. Instead of traditional surgery, which can be difficult for patients with underlying chronic liver disease, the multidisciplinary team opted for liver ablation using the AI-assisted segmentation system provided by Cascination. Arterial phase CT is done with the patient under general anaesthetic and a breath hold is coordinated by the anaesthetist before scanning. The pre-procedural CT is then segmented by AI and a metallic arm assists insertion of the ablation needle by the interventional radiologist with millimetre precision, far beyond what is possible with typical CT guided manual needle placement.  A second scan is performed to check needle positioning correctly within the tumour, which is especially difficult for high-up lesions near the diaphragm. The probe then delivers thermal energy, microwave or radiofrequency, directly to the cancerous cells, effectively destroying the abnormal cells and those within a 5-10 mm margin. Real-time confirmation of satisfactory ablation and margin is done with a final check CT, ensuring the entire tumour was completely destroyed while sparing healthy liver tissue.
