Abstract

To explore the value of ultrasound-guided percutaneous radiofrequency ablation (RFA) in designing the indication, treatment protocol and operational skills for patients with primary hepatocellular carcinoma (HCC) near the liver surface. Sixty-one HCC patients with 69 lesions, confirmed by clinical examination and pathology, underwent percutaneous radiofrequency ablation. The study included 40 cases of liver function Child-Pugh grade A and 21 cases of grade B. The average size of tumors was (3.8 ± 1.2) cm, tumor diameter ≥ 4 cm accounted for 39.1% (27/69 lesions), and the average age was 58.2 years (range, 35-76 years). Taking comprehensive measures, such as intraperitoneal injection of saline adjacent to the tumor before RFA, increasing the puncture sites on the surface of tumor to avoid overlapping of the central portion of tumor, repeated ablation of the needle track to reduce needle tract metastasis, avoid vertical puncture, and other additional measures, to improve the inactivation of tumors adjacent to the liver surface. Enhanced CT/MRI was performed to evaluate the curative effect at 1, 3, 6 and 24 months after the treatment. The inactivation rate of tumor was 98.6% (68/69 lesions) and local recurrence rate was 5.8%(4/69)...Continue Reading
