The clinical significance of different sequence in radiofrequency ablation of liver caner guided by ultrasound
Objective To evaluate the clinical significance of different sequences in Radiofrequency ablation of Liver caner guided by ultrasound. Methods Ultrasound guided percutaneous RFA was performed randomly by the same doctor in 62 tumors (clinically definited or pathology definited) of 62 patients with two defferent sequences. Group A was from center parts of a tumor to peripheries. Group B was opposite. The ablation effectiveness was evaluated by enhanced CT or ultrasound three months later. Results There were not significant differences of improved patients between Group A and Group B (P>0. 05), but sequence A and sequence B were statistically significant in better parts(the quantity: Group A > Group B)of improved patients. Conclusions The two strategies of RFA for treating hepatocellular carcinoma are utility, but A is better.
