Thoracic and diaphragmatic complications of percutaneous thermal ablation of hepatic malignant tumor / 中华超声影像学杂志

ABSTRACT

Objective To explore the thoracic and diaphragmatic complications of treating hepatic malignant tumor using thermal ablation techniques.Methods The patients received thermal ablations were involved as subjects from January 2002 to December 2013.The thoracic and diaphragmatic complications of treating hepatic malignant tumor with percutaneous thermal ablation were retrospectively analyzed.Results A total of 1 520 patients with 2 789 hepatic tumors [average largest diameter of tumor (2.30 ± 1 .03)cm] underwent 2 066 thermal ablation treatments.Five hundred and six radiofrequency ablation (RFA)and 1 560 microwave ablation procedures were performed,respectively.The complete ablation rate was 96.8%(2 701/2 789)at 1 month after treatment.The major thoracic and diaphragmatic complication rates were 0.8%(1 7/2 066 ),meanwhile the minor complication rates were 6.5% (134/2 066 ).Conclusions The thoracic and diaphragmatic complication rate of percutaneous thermal ablation is low in the treatment of hepatic malignant tumors.However,the major complications may cause serious consequences.Therefore, the patients of diaphragm-abutting liver tumors are fully assessed before thermal ablation treatments,and relevant prevention measures are completed.Open or laparoscope is used to assist thermal ablation treatment when necessary.
