Abstract:
Objective To analyze the causes,treatment and prevention of operation-related complications in liver malignancy patients after CT-guided percutaneous microwave coagulation therapy (PMCT).Methods A total of 68 patients with liver malignancy underwent CT-guided PMCT and their complications were analyzed retrospectively.Results The tumor diameter was 2.0-13.8 cm,mean 6.2 cm.Transcatheter arterial chemoembolization (TACE) was performed before PMCT in 64 patients,and 68 patients received 120 times of PMCT (1-8 times per patient).The main untoward reaction of PMCT was vagus nerve accentuation.Seven patients (7/120,5.83%) had complications including needle-tract implantation (n=2),liver abscess (n=2),pneumatothorax (n=1),cardiovascular accident (n=l) and enormous biloma with infection (n=l),6 were treated finally,and implanted tumor advanced in 1 patient.Conclusion CT-guided PMCT in liver malignancies is a safe therapeutic option with low rate of operation-related complications,which can be prevented and treated.Complications of PMCT are associated with the needle tract,frequency,coagulation range and perioperative management.
