From: Clinical Application of Artificial Ascites in assisting CT-guided Percutaneous Cryoablation of Hepatic Tumors Adjacent to the Gastrointestinal Tract

Figure 1

Artificial ascites assisting percutaneous cryoablation of a hepatic adenoma adjacent to the duodenum in a 34 year old female. (A) CT demonstrates a hepatic adenoma adjacent to the duodenum. (B) A 20-gauge introducer needle was inserted into the peritoneal cavity along the edge of the liver under CT guidance. (C) Then, a sufficient amount of 2.0% iodinated contrast was injected; we see the artificial ascites separates the tumor and adjacent duodenum. Two freeze/thaw cycles (12.0 min freeze, 3.0 min passive thaw) were applied. CT demonstrates the ice ball covering the tumor completely. (D) Contrast-enhanced CT showed tumor was complete ablation after 3 months followed up.
