Abstract

BACKGROUND: Liver cancer is one of the most common malignant tumors with a high incidence and mortality. Hepatitis-liver cirrhosis-liver cancer is known as the trilogy of liver cancer. At present, due to significant development of imaging interventions, they occupy an irreplaceable position in the field of liver cancer treatment, especially ultrasound-guided ablation. Because patients with liver cancer often present with liver cirrhosis, which leads to morphological deformation of the liver, it is difficult to perform a linear ablation of liver cancer in the areas near the phrenic top and within large blood vessels, among others. The present study reports on two cases of liver cancer that have been subjected to curvilinear ablation. After 1 mo, magnetic resonance imaging showed complete ablation, demonstrating that ultrasound-guided curved ablation is feasible and effective in the treatment of liver cancer.

CASE SUMMARY: Two patients were treated at the Liver Disease Department of the Xixi Hospital Affiliated to Zhejiang University of Chinese Medicine in 2019. Because the first liver cancer patient's tumor was located close to the diaphragm, it was difficult to complete a straight needle ablation procedure in one session. In order to achieve accurate and minimally invasive treatment of this tumor, a curved needle ablation procedure was designed. The second patient presented with a hepatic cyst in front of the tumor. In order not to damage the hepatic cyst, a looper needle ablation technique was used. The procedure was successfully completed in both cases.

CONCLUSION: Curved ablation is a new technique that can be used to treat tumors situated in a variety of locations, providing new ideas for interventional techniques. Its operation difficulty is higher and further animal experiments are necessary to improve the operation procedure.
