Aims and objectives
To explore the safety of differentimage guidances ofradiofrequency ablation(RFA) for hepatocellular carcinoma(HCC) and assess appropriate image guidanceto reduce complications.
Methods and materials
A retrospective study was made on clinical data of 729 treatments of RFA to 653 HCC nodules in 531 patients during a 10-year-period between January 2002 and June 2012.
Results
The number of treatments by CT-guided RFA,DSA(Digital Subtraction Angiography)-guided RFA and DSA combined with Dyna-CT guided RFA was 165,351 and 213,respectively.
The mortality was due to gastrointestinal hemorrhage and liver failure in 1 patient each,which accounted of 0.3%(2/729).Complications occurred in 4.1%(30/729): intra-abdominal hemorrhage in 0.5%(4/729),bile duct injury in 0.1%(1/729),liver failure in 0.1%(1/729),pulmonary complications(hemothorax and pulmonary infection) in 0.3%(2/729),pneumothorax in 1.8%(13/729),skin burn in 0.4%(3/729),portal vein injury in 0.4%(3/729),liver abscess in 0.1%(1/729)and gastrointestinal hemorrhage in 0.3%(2/729).
The rate of complications with CT-guided RFA(group I) was 10.9% (18/165),...
Conclusion
RFA using DSA-guided and DSA combined with Dyna-CT guided approach appeared to be safer for the treatment of HCC.
Complications after RFA could be reduced by cautious choice of suitable image guidance according to the sedimentation of lipiodol and the relationship between the lesions and important organs or tissues.
